  Dihydropyrazole derivatives as telomerase inhibitors: Structure-based design, synthesis, SAR and anticancer evaluation in vitro and in vivo

  摘要：

  It is of our interest to generate and identify novel compounds with regulation telomerase for cancer therapy. In order to carry out more rational design, based on structure-based drug design, several series of N-substituted-dihydropyrazole derivatives, totally 78 compounds as potential human telomerase inhibitors were designed and synthesized. The results demonstrated that some compounds had potent anticancer activity against four tumor cell lines, and showed good selectivity on tumor cells over somatic cells. By the modified TRAP assay, compound 13i exhibited the most potent inhibitory activity against telomerase with an IC50 value of 0.98 mu M. In vivo evaluation results indicated that compound 13i could inhibit growth of S180 and HepG2 tumor-bearing mice, and it also significantly enhanced the survival rate of EAC tumor-bearing mice. The further results in vivo confirmed that it could significantly improve pathological changes of N,N-diethylnitrosamine (DEN)-induced rat hepatic tumor. These data support further studies to assess rational design of more efficient telomerase inhibitors in the future. (C) 2016 Elsevier Masson SAS. All rights reserved.

  1-Acetyl- and 1-propionyl-2-pyrazolines 11-27 have been synthesized by the reaction of (3-coumarinyl)chalcones 1-10 with hydrazine in hot acetic acid or propionic acid. While 5-aryl-3-(3-coumarinyl)-1-phenyl-2-pyrazolines 28-35 have been prepared by the reaction of (3-coumarinyl)chalcones 1,3,5-10 with phenylhydrazine in hot pyridine. Structures of all new compounds have been elucidated by microanalyses
