  Synthesis and Antitumor Activity of Novel N’-(2-Benzylthiobenzenesulfonyl)-1H-pyrazole-1-amidine Derivatives

  摘要：

  A series of N'-(2-benzylthio-4-chlorobenzenesulfonyl)-1H-pyrazole-1-amidines (23-36) were synthesized by the reaction of 3-amino-2-(benzenesulfonyl)guanidines (18-22) with adequate 1,3-diketones. The compounds 23, 24, 26, 30, 31, 34 and 35 were tested in vitro in the full NCI 60 cell panel. The most potent compound in the series (26) showed substantial activity toward some cell lines of leukemia and cancer cells of lung, colon, CNS, melanoma, renal, prostate and breast (GI(50) in the range 2.30-9.47 mu M).

  Twenty four 1-[2-alkylthio-5-(azol-2 or 5-yl)-4-chlorobenzenesulfonyl]-3-hydroxyguanidines 6a-x have been synthesized in order to evaluate their biological activity. Compounds 6a, 6c, 6d, 6f, 6g, 6i-p, 6r-t, and 6v-x were tested for their in vitro anticancer activity at the US National Cancer Institute. The highest in vitro anticancer activity was found for compounds 6d, 6g and 6k with GI(50) average value in the range 1.62-1.86 mu M, and TGI mean values 3.72-4.47 mu M, whereas the remaining compounds showed broad spectrum of anticancer activity at low micromolar GI(50) level against all tested cancer cell lines. These results were subjected to CoMSIA analysis to establish quantitative structure activity relationships. The results evidence that potency of these compounds correlates mainly with hydrophobic and polar surface properties of substituents located both at 2 and 5 positions of 1-(4-chlorobenzenesulfonyl) moiety of investigated 3-hydroxyguanidine series.
