  Synthesis, in vitro and in vivo antitumor activity of pyrazole-fused 23-hydroxybetulinic acid derivatives

  摘要：

  A collection of pyrazole-fused 23-hydroxybetulinic acid derivatives were designed, synthesized and evaluated for their antitumor activity. Most of the newly synthesized compounds exhibited significant antiproliferative activity. Especially compound 15e displayed the most potent activity with the IC50 values of 5.58 and 6.13 mu M against B16 and SF763 cancer cell lines, respectively. Furthermore, the significant in vivo antitumor activity of 15e was validated in H22 liver cancer and B16 melanoma xenograft mouse models. The structure-activity relationships of these 23-hydroxybetulinic acid derivatives were also discussed based on the present investigation. (C) 2014 Elsevier Ltd. All rights reserved.
