Synthesis, anti-HSV-1, and cytotoxic activities of some new pyrazole- and isoxazole-based heterocycles

Abstract Ethyl 2,4-dioxo-4-(p-chloro)phenylbutyrate 2 obtained by condensation of 4-chloroacetophenone with diethyl oxalate was converted to 5-(4-chlorophenyl)-1- phenyl-1H-pyrazole-3-carbohydrazide 5 and 5-(4-chlorophenyl) isoxazole-3-carbohydrazide 6 in
