  Synthesis and in vitro antitumor activity of new 4,5-dihydropyrazole derivatives

  摘要：

  A series of 3,5-diaryl-4,5-dihydropyrazole regioisomers, and their 1-acetylated derivatives, bearing a 3,4,5-trimethoxyphenyl moiety combined with a variety of substituted phenyl rings, was synthesized and evaluated for antitumor activity. Results of the in vitro assay against a non-small cell lung carcinoma cell line (NCI-H460) showed several compounds to be endowed with cytotoxicity in micromolar to sub-micromolar range, depending on substitution pattern and position of aryl rings on 4,5-dihydropyrazole core. Potent and selective activity was also observed in the NCI 60 human cancer cell line panel. 5-(3,4,5-Trimethoxyphenyl) pyrazolines 31 and 39 were found to possess potent antiproliferative activity against SR and MDA-MB-435, with GI(50) inhibitory values in nanomolar range. Structure-activity relationships revealed that introduction of a (hydroxy) acetyl group at N-1 of inactive 5-(3,4,5-trimethoxyphenyl) pyrazolines, results in a clear in vitro activating effect. Compound 31 (IC(50) = 5.16 mu M) showed inhibition of tubulin polymerization comparable to that of CA-4 (IC(50) = 4.92 mu M). (C) 2010 Elsevier Ltd. All rights reserved.
