Abstract:Meayamycins are synthetic analogs of the natural product FR901464 and exhibit potent anticancer activity against human cancers. They bind SF3B1 and PHF5A, components of the human spliceosome, and alter pre-mRNA splicing. Detailed analysis of the active site led us to investigate a narrow pocket within the binding site which surrounds the ,-unsaturated amide portion of meayamycin. We describe the synthesis and biological activity of two new analogs bearing a methyl substituent on the or position of the amide. W… Show more
