Synthesis and biological activity of aminophthalazines and aminopyridazines as novel inhibitors of PGE2 production in cells
摘要:
This Letter reports the synthesis and biological evaluation of a collection of aminophthalazines as a novel class of compounds capable of reducing production of PGE(2) in HCA-7 human adenocarcinoma cells. A total of 28 analogs were synthesized, assayed for PGE2 reduction, and selected active compounds were evaluated for inhibitory activity against COX-2 in a cell free assay. Compound 2xxiv (R-1 = H, R-2 = p-CH3O) exhibited the most potent activity in cells (EC50 = 0.02 mu M) and minimal inhibition of COX-2 activity (3% at 5 mu M). Furthermore, the anti-tumor activity of analog 2vii was analyzed in xenograft mouse models exhibiting good anti-cancer activity. (C) 2012 Elsevier Ltd. All rights reserved.
