Chemoproteomic approach for discovering covalent ligands for diverse protein targets

Despite its power in identifying highly potent ligands for select protein targets, conventional medicinal chemistry is limited by its low throughput and lack of proteomic selectivity information. We seek to develop a chemoproteomic approach for discovering covalent ligands for protein targets in an unbiased, high-throughput manner. Tripartite probe compounds composed of a heterocyclic core, an electrophilic ‘warhead’ and an alkyne tag have been designed and synthesized for covalently labeling and identifying targets in cells. We have developed a novel condensation reaction to prepare 2-chloromethylquinoline (2-CMQ), a novel electrophilic heterocycle. These chloromethylquinolines potently and covalently bind to a number of cellular protein targets including Prostaglandin E Synthase 2 (PTGES2), a critical regulator of cell proliferation, apoptosis, angiogenesis, inflammation, and immune surveillance.

Thrombine inhibitors based on the amino acid sequence of hirudine

Locally-active anticoagulants and anti-inflammatory agents

A locally-activatable bivalent thrombin binding agent is provided having two thrombin binding moieties for non-overlapping sites on a surface of thrombin linked together by a linker. The linker is a polypeptide having 5 to 30 amino acid residues existing in a folded state under an environmental condition where the binding agent is inactive. The linker changes conformation from the folded state to an unfolded state in response to a change in bulk temperature and/or to the presence of hyper-mobile water thereby activating the binding agent. Such locally-activatable thrombin binding agents can be administered systemically while only targeting specific sites of coagulation or inflammation since the thrombin binding agent will only activate at the site where the existence of atherosclerotic plaques has changed the local bulk temperature and/or created hyper-mobile water sufficiently to unfold the linker and activate the binding agent. Such binding agents are useful as site-specific anti-coagulant, anti-thrombotic and/or anti¬ inflammatory agents.

Staphylococcal nuclease fusion proteins for the produciton of recombinant peptides

Peptides are produced as fusions with a suitable carrier protein. The carrier protein disclosed herein are adapted from the N-terminal domain of staphylococcus nuclease. This novel carrier protein acts to promote the over-expression of the peptide-protein fusion in the form of inclusion bodies, which minimizes in-cell proteolysis of desired peptides. The fusion protein is readily purified by conventional procedures or His-tag affinity chromatography when His-tag is inserted into the fusion protein. The target peptide is released from the purified fusion protein by a simple cleavage step and separated from the librated carrier protein by use of a reverse-phase HPLC process or by repeating the same affinity purification method. A particular advantage of the disclosed method, in addition to the obvious advantage of high yields, is its use for producing isotopically labeled peptides for NMR characterization of bioactive peptides and their interactions with target proteins.

Peptide inhibitors of thrombin as potent anticoagulants

The tetrapeptide Phe-Asn-Pro-Arg is a structurally-optimized sequence for binding to the active site of thrombin. By conjugating this tetrapeptide or variants thereof to a C-terminal fragment of hirudin, we were able to generate a series of new multivalent inhibitors of thrombin containing only genetically encodable natural amino acids. We found that synergistic binding to both the active site and an exosite of thrombin can be enhanced through substitutions of amino acid residues at the P 4 , P 3 and P 3′ sites of the active-site directed sequence, Xaa(P 4 )-Yaa(P 3 )-Pro(P 2 )-Arg(P 1 )-Pro(P 1′ )-Gln(P 2′ )-Zaa(P 3′ ). Complementary to rational design, a phage library was constructed to explore further the residue requirements at the P 4 , P 3 and P 3′ sites for multivalent and optimized bridge-binding. Panning of the phage library has led to thrombin-inhibitory peptides possessing strong anti-clotting activities in the low nanomolar range and yet interfering only partially with the catalytic active site of thrombin. In all, the availability of potent and genetically-encodable polypeptide inhibitors of thrombin opens the door for much wider applications of this clinically-successful class of anticoagulants, e.g. through more cost-effective recombinant peptide production, in areas such as gene therapy as well as to improve clinical efficacy/safety through the incorporation of homing peptides for targeted delivery.

Quantitative ranking of transient ligand binding to target biomolecules

There is provided a method of quantitatively ranking transient ligand binding to target biomolecules by means of NMR relaxation dispersion profiles. The present invention also relates to a method to identify ligand site obeying two-state and more complex binding behavior in a transient complex of a ligand with a target molecule, still with the use of NMR. There is also provided an efficient method to quantitate fast dissociation rates of ligands containing at least one magnetic nuclei by performing NMR relaxation dispersion experiments at different protein concentrations, enabling the evaluation of populations and exchange rates, and extending the practical applicability of the NMR relaxation dispersion experiments.

A chemoproteomic approach for discovering covalent ligands for diverse protein targets

Despite its power in identifying highly potent ligands for select protein targets, conventional medicinal chemistry is limited by its low throughput and lack of proteomic selectivity information. We seek to develop a chemoproteomic approach for discovering covalent ligands for protein targets in an unbiased, high-throughput manner. Tripartite probe compounds composed of a heterocyclic core, an electrophilic 'warhead' and an alkyne tag have been designed and synthesized for covalently labeling and identifying targets in cells. We have developed a novel condensation reaction to prepare 2-chloromethylquinoline (2-CMQ), a novel electrophilic heterocycle. These chloromethylquinolines potently and covalently bind to a number of cellular protein targets including Prostaglandin E Synthase 2 (PTGES2), a critical regulator of cell proliferation, apoptosis, angiogenesis, inflammation, and immune surveillance. The 2-CMQs that we have developed here are novel PTGES2 inhibitors that have the potential to serve as novel therapies for the treatment of human diseases such as inflammation. Beyond this case study, our methodology can be extended to additional electrophiles and scaffolds for discovering covalent ligands for diverse targets in the human proteome.
