  Synthesis and Biological Evaluation of Fully Functionalized seco-Pancratistatin Analogues

  摘要：

  The total synthesis of fully functionalized polyhydroxyamide B,C-seco-analogues of the anticancer compound pancratistatin (PST) (1) is reported. Key steps include an Evans' MgCl2-promoted anti-aldol reaction between a functionalized L-threose derivative and (R)-(+)-oxazolidinone to stereoselectively form the C-1/C-10b bond and a regiospecific radical-mediated oxidative fragmentation of a 1,3-benzylidene. The B,C-seco compounds 25 and 26 exhibited low activity (ED50 > 30 yg/mL) for inducing apoptosis in human cancer cells.

  Two total syntheses of fully functionalized seco-analogs of the anticancer compound pancratistatin are reported. Structure-activity relationship (SAR) studies identified potent and selective inhibitors of human cytochrome P450 3A4 (CYP3A4) and revealed several core pharmacophoric elements. These studies identify potential roadblocks and will guide the further development of a viable selective clinical pancratistatin derivative. (C) 2009 Elsevier Ltd. All rights reserved.
