A series of novel pyrazolo[1,5-a]pyrazin-4(5H)-one derivatives were synthesized by the reaction of ethyl 3-aryl-1-(2-bromoethyl)-1H-pyrazole-5-carboxylate and amine in the general heating condition and microwave-assisted condition. The structures of the compounds were determined by IR, (1)H NMR and mass spectroscopy, in addition, representative(More)
A series of novel 1-arylmethyl-3-aryl-1H-pyrazole-5-carbohydrazide hydrazone derivatives were synthesized and the effects of all the compounds on A549 cell growth were investigated. The results showed that all compounds had almost inhibitory effects on the growth of A549 cells. The study on structure-activity relationships and prediction of lipophilicities(More)
A series of novel 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carbohydrazide derivatives were synthesized, and the effects of the compounds on A549 cell growth were investigated. The results showed that all of the 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carbohydrazide derivatives 2 could inhibit the growth of A549 cells in dosage- and(More)
