  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.

  Synthesis, cytotoxic activity, and SAR analysis of the derivatives of taxchinin A and brevifoliol

  摘要：

  Twenty-one derivatives of taxchinin A (1) and brevifoliol (2) were synthesized and evaluated for cytotoxicity against human non-small lung cancer (A549) cell line. Nine derivatives showed potent activity with IC(50) values from 0.48 to 6.22 mu M. 5-Oxo-13-TBDMS-taxchinin A (11) and5-oxo-13,15-epoxy-13-epi-taxchinin A (15) are the most potent derivatives, with IC(50) at 0.48 and 0.75 mu M, respectively. The structure - activity relationship (SAR) of these compounds established that exocyclic unsaturated ketone at ring C is the key structural element for the activity, while the alpha,beta-unsaturated ketone positioned at ring A has no effect for the activity. The significant cytotoxicity of derivatives 11 and 15 may be due to the conformational change in the taxane rings. The 3D-QSAR study was conducted on this series of compounds, which provided optimal predictive comparative molecular field (CoM-FA) model with cross-validated r(2) (q(2)) value of 0.64.
