Synthesis and antitumor activity of 5,6-dihydro-17-hydroxy icogenin analogs
摘要:
Four 5,6-dihydro-17-hydroxy icogenin analogs were designed and synthesized. Their in vitro antitumor activities were tested by the standard MTT assay. Compound 22 (IC50 = 3.38-8.30 mu M) and compound 23 (IC50 = 1.90-9.69 mu M) showed potential antitumor activities against the entire tested seven cancer cell lines. The SAR (structure activity relationship) research showed that the introduction of 17-hydroxy lowered the antitumor activity to an extent. (C) 2012 Elsevier Masson SAS. All rights reserved.

In order to study the SAR of 5(6)-dihydro-OSW-1, eight 15(alpha)beta-O-glycosyl analogs (26-33) carrying three kinds of disaccharides including [beta-D-Xylp-(1-3)-alpha-L-Arap], [beta-D-Xylp-(1-4)-alpha-L-Arap] and [alpha-L-Rhap-(1-2)-(alpha)beta-D-Glcp] were designed and synthesized. Their in vitro antitumor activities were tested by the standard MTT assay which disclosed that compound 33 (IC50 = 0.28-0.52 mu M) showed potential antitumor activities. (C) 2011 Elsevier Ltd.
