Cytosine glycosides from Streptomyces griseochromogenes
摘要:
On supplementation of fermentations of Streptomyces griseochromogenes, an organism that produces the anti-fungal antibiotic blasticidin S (BS), with L-arginine hydroxamate in order to block the de novo biosynthesis of L-arginine, an essential precursor for BS, the accumulation of five new metabolites resulted. These new metabolites were purified by ion exchange chromatography and HPLC, and were characterized by NMR and mass spectroscopy and by chemical degradation. Two are normally very minor metabolites of S. griseochromogenes, while the other three are derived in part from the inhibitor that had been added to the fermentation.

The present invention provides compounds useful for inhibiting the ADAM-10 protein. Such compounds are useful in the in vitro study of the role of ADAM-10 (and its inhibition) in biological processes. The present invention also comprises pharmaceutical compositions comprising one or more ADAM-10 inhibitors according to the invention in combination with a pharmaceutically acceptable carrier. Such compositions are useful for the treatment of cancer, arthritis, and diseases related to angiogenesis. Correspondingly, the invention also comprises methods of treating forms of cancer, arthritis, and diseases related to angiogenesis in which ADAM-10 plays a critical role. The invention also provides methods for making bis-aryl ether sulfonyl chorides and ADAM-10 modulators therefrom.
