Synthesis and structure-activity relationships of novel 1-arylmethyl-3-aryl-1H-pyrazole-5-carbohydrazide derivatives as potential agents against A549 lung cancer cells.

A series of novel 1-arylmethyl-3-aryl-1H-pyrazole-5-carbohydrazide derivatives were synthesized, and the effects of all the compounds on A549 cell growth were investigated. The results showed that all the nine compounds had inhibitory effects on the growth of A549 cells and induced the cell apoptosis. The study on structure-activity relationships and prediction of lipophilicities of compounds showed that compounds with logP values in the range of 3.12-4.94 had more inhibitory effects on the growth of A549 cells.
