Highly Efficient CYP167A1 (EpoK) dependent Epothilone B Formation and Production of 7-Ketone Epothilone D as a New Epothilone Derivative
Since their discovery in the soil bacterium Sorangium cellulosum, epothilones have emerged as a valuable substance class with promising anti-tumor activity. Because of their benefits in the treatment of cancer and neurodegenerative diseases, epothilones are targets for drug design and pharmaceutical research. The final step of their biosynthesis - a cytochrome P450 mediated epoxidation of epoth...
متن کاملConformational Properties of Epothilone
The epothilones are macrolide natural products, produced by myxobacterium Sorangium cellulosum (So ce 90), which mimic the biological activity of the anticancer agent Taxol. These interesting compounds have been shown to bind tubulin, induce microtubule polymerization, and stabilize microtubule dynamics. Coupled with its biological activity, epothilone’s relatively simple structure has made it ...
متن کاملSynthesis and Biological Evaluation of 7-Deoxy-Epothilone Analogues
The synthesis of two deoxygenated analogues of potent epothilones is reported in an effort to analyze the relative importance of molecular conformation and ligand-target interactions to biological activity. 7-deoxy-epothilone D and 7-deoxy-(S)-14-methoxy-epothilone D were prepared through total synthesis and shown to maintain the conformational preferences of their biologically active parent co...
متن کاملDesign, synthesis and biological evaluation of bridged epothilone D analogues.
Six epothilone D analogues with a bridge between the C4-methyl and the C12-methyl carbons were prepared in an attempt to constrain epothilone D to its proposed tubulin-binding conformation. Ring-closing metathesis (RCM) was employed as the key step to build the C4-C26 bridge. In antiproliferative assays in the human ovarian cancer (A2780) and prostate cancer (PC3) cell lines, and also in tubuli...
متن کاملIn vivo evaluation of ixabepilone (BMS247550), a novel epothilone B derivative, against pediatric cancer models.
PURPOSE Vinca alkaloids, agents that cause depolymerization of microtubules, are highly active in treatment of many pediatric cancers. In contrast, taxanes, agents that stabilize microtubules, are far less effective against the same cancer types. The purpose of the current study was to evaluate the antitumor activity of ixabepilone, an epothilone B derivative representing a new class of microtu...
