  Synthesis and Antitumor Evaluation of New Polysubstituted Thiazole and Derived Thiazolo[4, 5-d]pyrimidine Systems

  摘要：

  The synthesis of three categories of compounds containing the 1 H-pyrazole ring linked to some dihydrothiazoles, thiazolidinones, and thiazolo[4,5-d]pyrimidines through different linkages is described. Nine of the newly synthesized target compounds were selected by the NCI for in-vitro antitumor screening. Four compounds, namely 4 a, 4 b, 13, and 14, exhibited a broad spectrum of antitumor activity against most of the tested tumor cell lines. Compound 4a, 3-phenyl-4-amino-5-(3,5-dimethyl-1-phenyl-1H-pyrazole-4-methylidenehydrazinocarbonyl)thiazole-2(3H)thione proved to be the most active antitumor agent in the present study with GI(50), TGI, and LC50 MG-MID values of 3.93, 41.7, and 91.2 muM, respectively. The same compound also exhibited high selectivity towards CNS SNB-75 and Ovarian IGROV1 cancer cell lines at both the GI(50) and TGI levels. Compound 4 b, 3-(4-chlorophenyl)-4-amino-5-(3,5-dimethyl-1-phenyl-1H-pyrazole-4-methylidenehydrazinocarbonyl)thiazole-2(3H)-thione showed nearly the same pattern of activity as 4 a but to a lesser extent. Compounds 13 and 14 displayed moderate antitumor activity against most of the tested tumor cell lines with GI(50). MG-MID values range of 20.4-80.6 muM and TGI MG-MID values of 55.5-95.5 muM.
