Macrolide biosynthesis: A single cytochrome P450, PicK, is responsible for the hydroxylations that generate methymycin, neomethymycin, and picromycin in Streptomyces venezuelae
摘要:
The final step in the biosynthesis of methymycin, neomethymycin, and picromycin is an hydroxylation, shown to be carried out by the cytochrome P-450 monooxygenase, PicK. Direct comparison of the relative k(cat)/K-m values for the two substrates, YC-17 and narbomycin, showed a threefold rate preference of picK for narbomycin. (C) 1998 Elsevier Science Ltd.

Disclosed herein are novel uses of avenaciolide derivatives and the preparation method of producing the same. The avenaciolide derivatives may suppress or inhibit the growth of gram-positive bacteria, including the notorious methicillin-resistant
Staphylococcus aureus
. Accordingly, the avenaciolides derivatives are potential lead compounds for the development of next generation antibiotics for the treatment of disease and/or disorders related to infection caused by gram-positive bacteria.

The present invention relates to compounds made by a subset of modules from one or more polyketide synthase (“PKS”) genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates (“bio-intermediates”) generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specificity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greatly simplified.
