The mycelium is separated from the culture broth by centrifugation or filtration and extracted with hot water. The aqueous extract may be treated with a proteolytic enzyme to digest the proteinaceous matter present and extracted with a water immiscible organic solvent, e.g. butyl alcohol, isobutyl alcohol and amyl alcohol and the solvent extract concentrated by evaporation.

The production of a selectively protected N-acylated derivative of an aminoglycosidic antibiotic

Принадлежит:

Aminoglycosidic antibiotic comprising a 6-0-(3''-aminoglycosyl)-2-deoxystreptamine optionally having a 4-0-(aminogycosyl) group, such as kanamycins, gentamicins, sisomicin, forms reversible complex with zinc cations by association of the zinc cations with some pairs of aminohydroxyl groups in the aminoglycoside, and the zinc-complexed amino groups are blocked from acylation. Reaction of this zinc complex with an acylation reagent having an amino-blocking acyl group brings about acylation of the non-complexed amino groups to give an N-acylated zinc complex, namely a complex of zinc cation with an N-acylated aminoglycosidic antibiotic derivative. Removal of zinc cations from N-acylated zinc complex yields a partially N-acylated aminoglycosidic antibiotic where 1- and 3''-amino groups are unprotected but all other amino groups protected with acyl group. Further reaction of this partially N-acylated product with a certain alkanoic acid or N-formyl-imidazole results in preferential acylation ...

More specifically, the present invention relates to a uridine-based MRI contrast agent that has high relaxivity, high binding affinity for and stability in human serum albumin, pH response, and high liver specificity.Magnetic resonance imaging (MRI) is a powerful noninvasive technique that provides high quality three dimensional images of tissues, including information on anatomy, function, and metabolism of tissue in vivo.The chelated Gd metal ion improves image contrast by decreasing the longitudinal relaxation time (T1) of proximal water protons, which appear brighter in the T1-weighted MR image. Current advanced medical diagnosis techniques stipulate high-resolution images with a high magnetic field scanner.However, current Gd-based contrast agents are incapable of meeting requirements as they do not have optimal relaxivity profiles at high magnetic fields. This requirement drives the research for smart contrast agents with high relaxivities (r1) for better tissue contrast at high magnetic fields and non-covalent binding affinity for human serum albumin (HSA) to enhance in ...

When the compounds are exposed to low energy X-ray (e.g., kilo electron volts KeV) Auger electrons are produced by the high Z elements present in the compound. Because lower energy is required when compared to typical radiotherapy, which uses therapeutic X-ray energy in the million electron volt range (MeV), the subject experiences lower collateral damage when compared to radiation therapy. Additionally, the presence of the anti-cancer agent provides a second mechanism for killing cancer cells. Methods for making and using the anti-cancer compounds are also described herein. 1.

A compound of the structure: This application claims priority to U.S. Ser. No. 62/129,319 filed on Mar. 6, 2015, U.S. Ser. No. 62/253,958 filed on Nov. 11, 2015, and U.S. Ser. No. 62/276,597 filed on Jan. 8, 2016, each of which is incorporated herewith in their entirety.The present invention is directed to nucleotide compounds and compositions and uses thereof to treat the Hepatitis C virus (“HCV”).Hepatitis C (HCV) is an RNA single stranded virus and member of the Hepacivirus genus. It is estimated that 75% of all cases of liver disease are caused by HCV. HCV infection can lead to cirrhosis and liver cancer, and if left to progress, liver failure which may require a liver transplant. Approximately 170-200 million people worldwide are infected, with an estimated 3-4 million infections in the United States.RNA polymerase is a key component in the targeting of RNA single stranded viruses. The HCV non-structural protein NS5B RNA-dependent RNA polymerase is a key enzyme responsible for initiating and catalyzing viral RNA synthesis. As a result, HCV NS5B is an attractive target for the current drug discovery and development of anti-HCV agents. There are two major subclasses of NS5B inhibitors: nucleoside analogs, which are anabolized to their active triphosphates—which act as alternative substrates for the polymerase—and non-nucleoside inhibitors (NNIs), which bind to allosteric regions on the protein. Nucleoside or nucleotide inhibitors mimic natural polymerase substrate and act as chain terminators. They inhibit the initiation of RNA transcription and elongation of a nascent RNA chain.In addition to targeting RNA polymerase, other RNA viral proteins may also be targeted in combination therapies. For example, HCV proteins that are additional targets for therapeutic approaches are NS3/4A (a serine protease) and NS5A (a non-structural protein that is an essential component of HCV replicase and exerts a range of effects on cellular pathways).In December 2013, the first ...
