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 tubulin assembly assay, all these compounds proved to be less active than epothilone D.
制备了六种表霉素D的类似物,这些类似物在C4-甲基和C12-甲基碳之间建立了桥接,旨在将表霉素D限制在其拟议的微管结合构象中。环关闭复分解反应(RCM)作为关键步骤,用于构建C4–C26桥。在人类卵巢癌(A2780)和前列腺癌(PC3)细胞系的抗增殖实验以及微管组装实验中,这些化合物的活性均低于表霉素D。
