  A-ring modified betulinic acid derivatives as potent cancer preventive agents

  摘要：

  Ten new 3,4-seco betulinic acid (BA) derivatives were designed and synthesized. Among them, compounds 7-15 exhibited enhanced chemopreventive ability in an in vitro short-term 12-O-tetradecanoylphorbol- 13-acetate (TPA) induced Epstein-Barr virus early antigen (EBV-EA) activation assay in Raji cells. Specifically, analogs with a free C-28 carboxylic acid, including 7, 8, 11, and 13, inhibited EBV-EA activation significantly. The most potent compound 8 displayed 100% inhibition at 1 x 10(3) mol ratio/TPA and 73.4%, 35.9%, and 8.4% inhibition at 5 x 10(2), 1 x 10(2), and 1 x 10 mol ratio/TPA, respectively, comparable with curcumin at high concentration and better than curcumin at low concentration. The potent chemopreventive activity of novel seco A-ring BAs (8 and 11) was further confirmed in an in vivo mouse skin carcinogenesis assay. (C) 2013 Elsevier Ltd. All rights reserved.

  Bio-assay-guided fractionation of the CHCl3-soluble extract from the leaves of Viburnum aboricolum led to the isolation of a novel secobetulinic acid 3,4-lactone, viburolide (=(6β)-4,6-dihydroxy-3,4-secolup-20(29)-ene-3,28-dioic acid 3,4-lactone; 1). This is the first lupane-type compound possessing such a lactone skeleton from natural products. Its structure was elucidated by spectral analysis and
