  Synthesis and in vitro antitumor activity of new series of benzothiazole and pyrimido[2,1-b]benzothiazole derivatives

  摘要：

  New series of benzothiazole and pyrimido[2,1-b]benzothiazole derivatives were synthesized and characterized by analytical and spectrometrical methods (IR, HRMS, H-1 and C-13 NMR). Nineteen of the synthesized compounds were selected by the National Cancer Institute (NCI), USA, to be screened for their antitumor activity at a single dose (10 mu M) against a panel of 60 cancer cell lines. The most active compounds, 4, 6, 10, 14, 17 and 20 were selected for further evaluation at five dose level screening. Compounds 17 (GI(50) = 0.44 mu M, TGI = 1.2 mu M and LC50 MG-MID = 6.6 mu M) and 4 (GI(50) = 0.77 mu M, TGI = 2.08 mu M and LC50 MG-MID = 11.74 mu M) were proved to be the most active members in this study. 3D and 2D pharmacophoric maps for the structural features of both compounds were studied.
