  Dual-Functional abeo-Taxane Derivatives Destabilizing Microtubule Equilibrium and Inhibiting NF-κB Activation

  摘要：

  Taxchinin A, with a 11(15 -> 1)-abeo-taxane skeleton, is a major, but inactive taxoid contained in leaves of Taxus chinensis. In our design of dual-functional antitumor abeo-taxane derivatives, two fragments from antitumor agents with different molecular targets (the N-acyl-3'-phenylisoserine side chain from the antimitotic agent paclitaxel and an alpha,beta-unsaturated carbonyl system from NF-kappa B inhibitors) were incorporated into the scaffold of taxchinin A. The resulting compounds displayed broad inhibitory effects against proliferation of tumor cell lines, with notable selectivity toward colon cancer, melanoma, and renal cancer, when evaluated in the NCI-60 human tumor cell line screening panel. On the basis of the NCI-60 assay data, structure-activity relationship (SAR) correlations were elucidated. Mechanistic studies indicated that this new compound type can both destabilize microtubules and inhibit NF-kappa B activation, thereby inducing tumor cell apoptosis. This first report of the dual-functional taxoid-core compounds thus provides new opportunities for future drug development based on natural axoid scaffolds.

  Two interesting unprecedented fragmentations of 13-oxo-taxyunnansin A (3), initiated by treatment with (t)BuOK and Red-Al, respectively, have been discovered, optimized and successfully applied to the synthesis of novel abeo-paclitaxel and abeo-docetaxel derivatives. Eight new derivatives of abeo-paclitaxel and abeo-docetaxel possessing the structurally simplified 11 (15 -> 1)-abeo-taxane skeleton with an oxetane ring and pi bond conjugate system were accordingly prepared for the further evaluation of anticancer activities.
