WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 PYRIDINE AND PYRAZINE DERIVATIVES AS PROTEIN KINASE MODULATORS BACKGROUND This application claims priority to U.S. provisional application Serial No. 61/273,154, filed July 30, 2009, and U.S. provisional application Serial No. 61/357,720, filed June 23, 2010, the contents of which are incorporated herein by reference in their entirety. [0021 The search for new therapeutic agents has been greatly aided in recent years by a better understanding of the structure of enzymes and other biomolecules associated with diseases. One important class of enzymes that has been the subject of extensive study is protein kinases. Protein kinases constitute a large family of structurally related enzymes that are responsible for the control of a variety of signal transduction processes within the cell. (Hardie, G. and Hanks, S. The Protein Kinase Facts Book, I and II, Academic Press, San Diego, Calif.: 1995). Protein kinases are thought to have evolved from a common ancestral gene due to the conservation of their structure and catalytic function. Almost ail kinases contain a similar 250-300 amino acid catalytic domain. The kinases may be categorized into families by the substrates they phosphorylate (e.g., protein-tyrosine, protein-serine/threonine, lipids, etc.). Sequence motifs have been identified that generally correspond to each of these kinase families (See, for example, Hanks, S. K., Hunter, T., FASEB J. 1995, 9, 576-596; Knighton et al., Science 1991, 253,407-414; Hiles et al., Cell 1992, 70, 419-429; Kunz et al., Cell 1993, 73, 585-596; Garcia-Bustos et al., EMBO J. 1994, 13, 2352-2361). 10041 Many diseases are associated with abnormal cellular responses triggered by the protein kinase-mediated events described above. These diseases include, but are not limited to, autoimmune diseases, inflammatory diseases, bone diseases, metabolic diseases, neurological and neurodegenerative diseases, cancer, cardiovascular diseases, allergies and asthma, Alzheimer's disease, viral diseases, and hormone-related diseases. Accordingly, there has been a substantial effort in medicinal chemistry to find protein kinase inhibitors that are effective as therapeutic agents. [0051 The cyclin-dependent kinase (CDK) complexes are a class of kinases that are targets of interest. These complexes comprise at least a catalytic (the CDK itself) and a regulatory (cyclin) subunit. Some of the more important complexes for cell cycle regulation WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 include cyclin A (CDK 1-also known as cdc2, and CDK2), cyclin B l-B3 (CDK1) and cyclin DlD3 (CDK2, CDK4, CDK5, CDK6), cyclin E (CDK2). Each of these complexes is involved in a particular phase of the cell cycle. Additionally, CDKs 7, 8, and 9 are implicated in the regulation of transcription. The activity of CDKs is regulated post4ranslationally, by transitory associations with other proteins, and by alterations of their intracellular localization. Tumor development is closely associated with genetic alteration and deregulation of CDKs and their regulators, suggesting that inhibitors of CDKs may be useful anti-cancer therapeutics. Indeed, early results suggest that transformed and normal cells differ in their requirement for, e.g., cyctin A/CDK2 and that it may be possible to develop novel antineoplastic agents devoid of the general host toxicity observed with conventional cytotoxic and cytostatic drugs. While inhibition of cell cycle-related CDKs is clearly relevant in, e.g., oncology applications, inhibition of RNA polymerase-regulating CDKs may also be highly relevant in cancer indications. The CDKs have been shown to participate in cell cycle progression and cellular transcription, and loss of growth control is linked to abnormal cell proliferation in disease (see e.g., Malumbres and Barbacid, Nat. Rev. Cancer 200 l, 1:222). Increased activity or temporally abnormal activation ofcyclin-dependent kinases has been shown to result in the development of human tumors (Sherr C. J., Science 1996, 274 : 1672-1677). Indeed, human tumor development is commonly associated with alterations in either the CDK proteins themselves or their regulators (Cordon-Cardo C., Am. J. Pari/701. 1995; 147: 545-560; Karp J. E. and Broder S., Nat. Med. 1995; l: 309-320; Hall M. et al., Adv. Cancer Res. 1996; 68: 671o8). 10081 Naturally occurring protein inhibitors of CDKs such as p16 and p27 cause growth inhibition in vitro in lung cancer cell lines (Kamb A., Curr. Top. MicrobioI. Immunol. 1998; 227: 139-148). 1009] CDKs 7 and 9 seem to play key roles in transcription initiation and elongation, respectively (see, e.g., Peterlin and Price. Cell 23: 297-305, 2006, Shapiro. J. Clin. Oncot. 24: 1770-83, 2006;). Inhibition of CDK9 has been linked to direct induction ofapoptosis in tumor cells of hematopoetic lineages through down-regulation of transcription of antiapoptotic proteins such as Moll (Chao, S.-H. et al. J. Biol. Chem. 2000;275:28345-28348; Chao, S.-H. et al. J. Biol. Chem. 200t;276:31793-31799; Lam et. al. Genome Biology 2: 0041.1-11, 2001; WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 Chen et al. Blood 2005;106:2513; MacCallurn et al. Cancer Res. 2005;65:5399; and Alvi et al. Blood 2005;105:4484). In solid tumor cells, transcriptional inhibition by downregulation of CDK9 activity synergizes with inhibition of cell cycle CDKs, for example CDK1 and 2, to induce apoptosis (Cal, D.-P., Cancer Res 2006, 66:9270. Inhibition of transcription through CDK9 or CDK7 may have selective non-proliferative effect on the tumor cell types that are dependent on the transcription of mRNAs with short hall lives, for example Cyclin D l in Mantle Cell Lymphoma. Some transcription factors such as Myc and NF-kB selectively recruit CDK9 to their promoters, and tumors dependent on activation of these signaling pathways may be sensitive to CDK9 inhibition. [00101 Small molecule CDK inhibitors may also be used in the treatment of cardiovascular disorders such as restenosis and atherosclerosis and other vascular disorders that are due to aberrant cell proliferation. Vascular smooth muscle proliferation and intimal hyperplasia following balloon angioplasty are inhibited by over-expression of the cyclindependent kinase inhibitor protein. Moreover, the puñne CDK2 inhibitor CVT-313 (Ki = nM) resulted in greater than 80% inhibition of neointima formation in rats. CDK inhibitors can be used to treat diseases caused by a variety of infectious agents, including fungi, protozoan parasites such as Plasmodium falciparum, and DNA and RNA viruses. For example, cyclin-dependent kinases are required for viral replication following infection by herpes simplex virus (HSV) (Schang L. M. et al., J. Virol. 1998; 72: 5626) and CDK homologs are known to play essential roles in yeast. [00121 Inhibition of CDK9/cyclin T function was recently linked to prevention of H1V replication and the discovery of new CDK biology thus continues to open up new therapeutic indications for CDK inhibitors (Sausville, E. A. Trends Mole. Med. 2002, 8, $32- $37). 10013] CDKs are important in neutrophil-mediated inflammation and CDK ìnhibitors promote the resolution of inflammation in animal models. (Rossi, A.G. et al, Nature Med. 2006, 12:1056). Thus CDK inhibitors, including CDK9 inhibitors, may act as anti-inflammatory agents. [00141 Selective CDK inhibitors can be used to ameliorate the effects of various autoimmune disorders. The chronic inflammatory disease rheumatoid arthritis is characterized by synovial tissue hyperplasia; inhibition of synovial tissue proliferation should minimize WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 inflammation and prevent joint destruction. In a rat model of arthritis, joint swelling was substantially inhibited by treatment with an adenovirus expressing a CDK inhibitor protein p 16. CDK inhibitors are effective against other disorders of cell proliferation including psoriasis (characterized by keratinocyte hyperproliferation), glomerulonephritis, chronic inflammation, and lupus. Certain CDK inhibitors are useful as chemoprotective agents through their ability to inhibit cell cycle progression of normal untransformed cells (Chen, et al. J. Natl. Cancer Institute, 2000; 92: 1999-2008). Pro-treatment of a cancer patient with a CDK inhibitor prior to the use of cytotoxic agents can reduce the side effects commonly associated with chemotherapy. Normal proliferating tissues are protected from the cytotoxic effects by the action of the selective CDK inhibitor. Accordingly, there is a great need to develop inhibitors of protein kinases, such as CDKI, CDK2, CDK3, CDK4, CDK5, CDK6, CDK7, CDK8 and CDK9, as well as combinations thereof. Summary of the Invention There remains a need for new treatments and therapies for protein kinaseassociated disorders. There is also a need for compounds useful in the treatment or prevention or amelioration of one or more symptoms of cancer, inflammation, cardiac hypertrophy, and HIV. Furthermore, there is a need for methods for modulating the activity of protein kinases, such as CDK1, CDK2, CDK3, CDK4, CDK5, CDK6, CDK7, CDK8 and CDK9, and combinations thereof, using the compounds provided herein.

As used herein, the term "protein kinase-associated disorder" includes disorders and states (e.g., a disease state) that are associated with the activity of a protein kinase, e.g., the CDKs, e.g., CDKI, CDK2 and/or CDK9. Nonlimiting examples of protein kinase-associated disorders include abnormal cell proliferation (including protein kinase-associated cancers), viral infections, fungal infections, autoimmune diseases and neurodegenerative disorders. 100155] Non-limiting examples ofprotein-kinase associated disorders include proliferative diseases, such as viral infections, auto-immune diseases, fungat disease, cancer, psoriasis, vascular smooth cell proliferation associated with atherosclerosis, pulmonary fibrosis, arthritis glomerulonephritis, chronic inflammation, neurodegenerative disorders, such as Alzheimer's disease, and post-surgical stenosis and restenosis. Protein kinase-associated diseases also include diseases related to abnormal cell proliferation, including, but not limited to, cancers of the breast, ovary, cervix, prostate, testis, esophagus, stomach, skin, lung, bone, colon, pancreas, thyroid, biliary passages, buccal cavity and pharynx (oral), lip, tongue, mouth, pharynx, small intestine, colon-rectum, large intestine, rectum, brain and central nervous system, glioblastoma, neuroblastoma, keratoacanthoma, epidermoid carcinoma, large cell carcinoma, adenocarcinoma, adenocarcinoma, adenoma, adenocarcinoma, follicular carcinoma, undifferentiated carcinoma, papillary carcinoma, seminoma, melanoma, sarcoma, bladder carcinoma, liver carcinoma, kidney carcinoma, myeloid disorders, lymphoid disorders, Hodgkin's, hairy cells, and leukemia. Additional non-limiting examples of protein kinase-associated cancers include carcinomas, hematopoietic tumors of lymphoid lineage, hematopoietic tumors ofmyeloid lineage, tumors of mesenchymal origin, tumors of the central and peripheral nervous system, melanoma, seminoma, teratocarcinoma, osteosarcoma, xenoderoma pigmentosum, keratoctanthoma, thyroid follicular cancer and Kaposi's sarcoma. WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 Protein kinase-associated disorders include diseases associated with apoptosis, including, but not limited to, cancer, viral infections, autoimmune diseases and neurodegenerative disorders. Non-limiting examples ofprotein-kinase associated disorders include viral infections in a patient in need thereof, wherein the viral infections include, but are not limited to, HIV, human papilloma virus, herpes virus, poxyirus, Epstein-Barr virus, Sindbis virus and adenovirus. 100159] Non-limiting examples of protein-kinase associated disorders include tumor angiogenesis and metastasis.

Further non-limiting examples of protein-kinase associated disorders include those associated with infectious agents, including yeast, fungi, protozoan parasites such as Plasitiodium falciparum, and DNA and RNA viruses. 100161] In another embodiment, the compound of the present invention is further characterized as a modulator of a combination of protein kìnases, e.g., the CDKs, e.g., CDK 1, CDK2 and/or CDK9. In certain embodiments, a compound of the present invention is used for protein kinase-associated diseases, and/or as an inhibitor of any one or more protein kinases. It is envisioned that a use can be a treatment of inhibiting one or more isoforms of protein kinases. The compounds of the invention are inhibitors of cyclin-dependent kinase enzymes. Without being bound by theory, inhibition of the CDK4/cyclin D1 complex blocks phosphorylation of the Rb/inactive E2F complex, thereby preventing release of activated E2F and ultimately blocking E2F-dependent DNA transcription. This has the effect of inducing GI cell cycle arrest. In particular, the CDK4 pathway has been shown to have tumor-specific deregulation and cytotoxic effects. Accordingly, the ability to inhibit the activity of combinations of CDKs will be of beneficial therapeutic use. 100163] Furthermore, the cell's ability to respond and survive chemotherapeutic assault may depend on rapid changes in transcñption or on activation of pathways which are highly sensitive to CDK9/cyclinTl (PTEF-b) activity. CDK9 inhibition may sensitize cells to TNFalpha or TRAIL stimulation by inhibition of NF-kB, or may block growth of cells by WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 reducing myc-dependent gene expression. CDK9 inhibition may also sensitize cells to genotoxic chemotherapies, HDAC inhibition, or other signal transduction based therapies. As such, the compounds of the invention can lead to depletion of antiapoptotic proteins, which can directly induce apoptosis or sensitize to other apoptotic stimuli, such as cell cycle inhibition, DNA or microtubule damage or signal transduction inhibition. Depletion of anti-apoptotic proteins by the compounds of the invention may directly induce apoptosis or sensitize to other apoptotic stimuli, such as cell cycle inhibition, DNA or microtubule damage or signal transduction inhibition.

Examples of organic salts of acid compounds include, but are not limited to, procaine, dibenzylamine, N-ethylpiperidine, N,N'- dibenzylethylenediamine, and tñethylamine salts. Pharmaceutically acceptable metabolites and prodrugs of the compounds referred to in the formulas herein are also embraced by the invention. The term "pharmaceutically WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 acceptable prodrugs" as used herein refers to those prodrugs of the compounds of the present invention which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response, and the like, commensurate with a reasonable benefit/risk ratio, and effective for their intended use, as well as the zwitterionic forms, where possible, of the compounds of the invention. The term "prodrug" refers to compounds that are rapidly transformed in vivo to yield the parent compound of the above formula, for example by hydrolysis in blood. A thorough discussion is provided in T. Higuchi and V. Stella, PRO-DRUGS AS NOVEL DELIVERY SYSTEMS, Vol. 14 of the A.C.S. Symposium Series, and in Edward B. Roche, ed., BIOREVERSIBLE CARRIERS IN DRUG DESIGN, American Pharmaceutical Association and Pergamon Press, 1987. Pharmaceutically acceptable esters of the compounds referred to in the formulas herein are also embraced by the invention. As used herein, the term "pharmaceutically acceptable ester" refers to esters, which hydrolyze in vivo and include those that break down readily in the human body to leave the parent compound or a salt thereof. Suitable ester groups include, for example, those derived from pharmaceutically acceptable aliphatic carboxylic acids, particularly alkanoic, alkenoic, cycloalkanoic and alkanedioic acids, in which each alkyl or alkenyl moiety advantageously has not more than 6 carbon atoms. Examples of particular esters include formates, acetates, propionates, butyrates, acrylates and ethylsuccinates. The invention further provides deuterated versions of the above-described compounds. As used herein, "deuterated version" refers to a compound in which at least one hydrogen atom is enriched in the isotope deuterium beyond the natural rate of deuterium occurrence. Typically, the hydrogen atom is enriched to be at least 50% deuterium, frequently at least 75% deuterium, and preferably at least about 90% deuterium. Optionally, more than one hydrogen atom can be replaced by deuterium. For example, a methyl group can be deuterated by replacement of one hydrogen with deuterium (i.e., it can be --CH2 D), or it can have ail three hydrogen atoms replaced with deuterium (i.e., it can be -CD3 ). In each case, D signifies that at least 50% of the corresponding H is present as deuterium. [002191 A substantially pure compound means that the compound is present with no more than 15% or no more than 10% or no more than 5% or no more than 3% or no more than 1% of the total amount of compound as impurity and!or in a different form. For instance, substantially pure S,S compound means that no more than 15% or no more than 10% or no more WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 than 5% or no more than 3% or no more than 1% of the total R,R; S,R; and R,S forms are present. As used herein, "therapeutically effective amount" indicates an amount that results in a desired pharmacological and/or physiological effect for the condition. The effect may be prophylactic in terms of completely or partially preventing a condition or symptom thereof and/or may be therapeutic in terms of a partial or complete cure for the condition and/or adverse effect attributable to the condition. Therapeutically effective amounts of the compounds of the invention generally include any amount sufficient to detectably inhibit Raf activity by any of the assays described herein, by other Rafkinase activity assays known to those having ordinary skill in the art or by detecting an inhibition or alleviation of symptoms of cancer. [002211 As used herein, the term "pharmaceutically acceptable carrier," and cognates thereof, refers to adjuvants, binders, diluents, etc. known to the skilled artisan that are suitable for administration to an individual (e.g., a mammal or non-mammal). Combinations of two or more carders are also contemplated in the present invention. The pharmaceutically acceptable cartier(s) and any additional components, as described herein, should be eompatiblë for use in the intended route of administration (e.g., oral, parenteral) for a particular dosage form. Such suitability will be easily recognized by the skilled artisan, particularly in view of the teaching provided herein. Pharmaceutical compositions described herein include at least one pharmaceutically acceptable cartier or excipient; preferably, such compositions include at least one carrier or excipient other than or in addition to water. [002221 As used herein, the term "pharmaceutical agent" or "additional pharmaceutical agent," and cognates of these terms, are intended to refer to active agents other than the claimed compounds of the invention, for example, drugs, which are administered to elicit a therapeutic effect. The pharmaceutical agent(s) may be directed to a therapeutic effect related to the condition that a claimed compound is intended to treat or prevent (e.g., conditions mediated by Raf kinase, including, but not limited to those conditions described herein (e.g., cancer)) or, the pharmaceutical agent may be intended to treat or prevent a symptom of the underlying condition (e.g., tumor growth, hemorrhage, ulceration, pain, enlarged lymph nodes, cough, jaundice, swelling, weight loss, cachexia, sweating, anemia, paraneoplastie phenomena, thrombosis, etc.) or to further reduce the appearance or severity of side effects of administering a claimed compound. WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 When used with respect to methods of treatment/prevention and the use of the compounds and formulations thereof described herein, an individual "in need thereof" may be an individual who has been diagnosed with or previously treated for the condition to be treated. With respect to prevention, the individual in need thereof may also be an individual who is at risk for a condition (e.g., a family history of the condition, life-style factors indicative of risk for the condition, etc.).

The analytical columns were reversed phase Phenomenex Luna C18 5 4.6 x 50 mm, from Alltech (Deerfield, IL). A gradient elution was used (flow 2.5 mL/min), typically starting with 5 % acetonitrile/95 % water and progressing to % acetonitrile over a period of 10 minutes. Ail solvents contained 0.1% trifluoroacetic acid (TFA). Compounds were detected by ultraviolet light (UV) absorption at either 220 or 254 nm. HPLC solvents were from Burdick and Jackson (Muskegan, MI), or Fisher Scientific (Pittsburgh, PA). In some instances, purity was assessed by thin layer chromatography (TLC) using glass or plastic backed silica gel plates, such as, for example, Baker-Flex Silica Gel I B2-F flexible sheets. TLC results were readily detected visually under ultraviolet light, or by employing well known iodine vapor and other various staining techniques. Mass spectrometric analysis was performed on LCMS instruments: Waters System (Acuity UPLC and a Micromass ZQ mass spectrometer; Column: Acuity HSS C 18 1.8micron, 2.1 x 50 mm; gradient: 5-95 % acetonitrile in water with 0.05 % TFA over a 1.8 min period ; flow rate 1.2 mL/min; molecular weight range 200-1500; cone Voltage 20 V; column temperature 50 °C). Ail masses were reported as those of the protonated parent ions. GCMS analysis is performed on a Hewlett Packard instrument (HP6890 Series gas chromatograph with a Mass Selective Detector 5973; injector volume: 1 IL; initial column temperature: 50 °C; final column temperature: 250 oC; ramp time: 20 minutes; gas flow rate: 1 mL/min; column: 5 % phenyl methyl siloxane, Model No. HP 190915-443, dimensions: 30.0 m x 25 m x 0.25 m). Nuclear magnetic resonance (NMR) analysis was performed on some of the compounds with a Varian 300 MHz NMR (Palo Alto, CA) or Varian 400 MHz MR NMR (Pato Alto, CA). The spectral reference was either TMS or the known chemical shitt of the WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 solvent. Some compound samples were run at elevated temperatures (e.g., 75 oC) to promote increased sample solubility. The purity of some of the compounds is assessed by elemental analysis (Desert Analytics, Tucson, AZ). |00242] Melting points are determined on a Laboratory Devices Mel-Temp apparatus (Holliston, MA). 100243] Preparative separations are carried out using a Combiflash Rf system (Teledyne lsco, Lincoln, NE) with RediSep silica gel cartridges (Teledyne lsco, Lincoln, NE) or SiliaSep silica gel cartridges (Siticycle Inc., Quebec City, Canada) or by flash column chromatography using silica gel (230-400 mesh) packing material, or by HPLC using a Waters 2767 Sample Manager, C-18 reversed phase column, 30X50 mm, flow 75 mL/min. Typical solvents employed for the Combiflash Rf system and flash column chromatography are dichloromethane, methanol, ethyl acetate, hexane, heptane, acetone, aqueous ammonia (or ammonium hydroxide), and triethyl amine. Typical solvents employed for the reverse phase HPLC are varying concentrations of acetonitrile and water with 0.1% trifluoroacetic acid.

X can be a functional group like CI, Br, I or OTf. Compound I can be converted into boronic acid or boronic ester II by: 1002701 1) PdCl2 (dppf) DCM adduct, potassium acetate, bis(pinacolato)diboron heating from 30 - 120 °C in solvents such as THF, DMF, DME, DMA, toluene and dioxane; and 2) In a solvent such as THF or diethylether, anion halogen exchange by addition of nBuLi or LDA followed by quenching the anion with triisopropyl borate. Upon hydrolysis a moronic acid can be obtained. Suzuki cross-coupling reaction between compound II and pyridine or pyrazine III then gives bi-heteroaryl intermediate IV. The SNAR reaction between IV and a functionalized amine NH2 RI' under basic condition (DIEA, TEA, lutidine, pyridine) in a solvent such as DMF, THF, DMSO, NMP, dioxane with heating (30-130 °C) can give compound V. When Ri' is not identical to R1 , further functional munipulation is needed to obtain VI. When RI' is identical to R1, compound V will be the same as compound VI.

The Phospho-5TAMRA-cdk7tide peptide substrate is bound to the IMAP Progressive Binding Reagent. The binding of the IMAP Progressive Binding Reagent changes the fluorescence polarization of the 5TAMRA-cdk7tide peptide which is measured at an excitation of 53 lnm and FP emission of 595nm. Assays are carded out in 100mM Tñs, pli=7.2, 10mM MgCI2, 0.05% NAN3, 0.01% Tween-20, I mM dithíothreitol and 2.5% dimethyl sulfoxide. IMAP Progressive Binding Reagent is diluted 1:800 in 100% IX Solution A from Molecular Devices, cat#R7285. 1006841 General protocol is as follows: To 10ul of cdk9/cyclinT 1, 0.5ul of test compound in dimethyl sulfoxide is added. 5TAMRA-cdk7tide and ATP are mixed. 10ul of the 5TAMRA-cdk7tide/ATP mix is added to start the reaction. The reaction is allowed to proceed for 4.5hrs. 60uL of IMAP Progressive Binding Reagent is added. After > lhr of incubation, plates are read on the Envision 2101 from Perkin-Elmer. The assay is run in a 384-well format using black Coming plates, cat#3573. Cdk9/c¥clinT 1 Alpha Screen Protocol 100685] Full length wild type Cdk9/cyclin T I is purchased from Invitogen, cat#PV4131.

The Alpha Screen Protein A detection kit containing donor and acceptor beads is purchased from PerkinElmer Life Sciences. The final concentration of both donor and acceptor beads is 15ug/ml. Alpha Screen is used for detection. The biotinylated-cdk7tide peptide is WO 2011/012661 CA 02767066 2011-12-30 PCT/EP2010/060984 phosphorylated by cdk9/cyclinT1 using the ATP substrate. The biotinylated-cdk7tide peptide substrate is bound to the streptavidin coated donor bead. The antibody is bound to the protein A coated acceptor bead. The antibody will bind to the phosphorylated form of the biotinylatedcdk7tide peptide substrate, bringing the donor and acceptor beads into close proximity. Laser irradiation of the donor bead at 680nm generates a flow of short-lived singlet oxygen molecules. When the donor and acceptor beads are in close proximity, the reactive oxygen generated by the irradiation of the donor beads initiates a luminescence/fluorescence cascade in the acceptor beads. This process leads to a highly amplified signal with output in the 530-620nm range.
