  4,5‐Diaryl‐3‐aminopyrazole Derivatives as Analogs of Combretastatin A‐4: Synthesis and Biological Evaluation

  摘要：

  A series of cis‐restricted 4,5‐diaryl‐3‐aminopyrazole derivatives were synthesized and tested for their cytotoxic activity in vitro against five human cancer cell lines (K562, ECA‐109, A549, SMMC‐7721, and PC‐3). Compounds 5a, 5b, 5d, and 6b showed potent cytotoxicity against all tested cell lines. Primary mechanism research on compound 5a indicated that it was a potent inhibitor of tubulin polymerization, arresting cell cycle in G₂/M phase. The docking research showed the conformation of 5a overlaps well with CA‐4 in the crystallized protein complex, suggesting the 4,5‐diaryl‐3‐aminopyrazoles were good mimics of CA‐4.

  cis-Restricted 3-Aminopyrazole Analogues of Combretastatins: Synthesis from Plant Polyalkoxybenzenes and Biological Evaluation in the Cytotoxicity and Phenotypic Sea Urchin Embryo Assays

  摘要：

  We have synthesized a series of novel cis-restricted 4,5-polyalkoxydiaryl-3-aminopyrazole analogues of combretastatins via short synthetic sequences using building blocks isolated from dill and parsley seed extracts. The resulting compounds were tested in vivo in the phenotypic sea urchin embryo assay to reveal their antimitotic and antitubulin effects. The most potent aminopyrazole, 14a, altered embryonic cell division at 10 nM concentration, exhibiting microtubule-destabilizing properties. Compounds 12a and 14a displayed pronounced cytotoxicity in the NCI60 anticancer drug screen, with the ability to inhibit growth of multidrug-resistant cancer cells.
