Synthesis, characterization, antiamoebic activity and cytotoxicity of novel series of pyrazoline derivatives bearing quinoline tail
摘要:
The cyclization of chalcones (1a-1j) with 2-(quinolin-8-yloxy) acetohydrazide (2) under basic condition led to the formation of new compounds. pyrazoline derivatives (3a-3j) In vitro antiamoebic activity was performed against HM1: IMSS strain of Entamoeba histolytica The results showed that the compounds 3d, 3g, 3h, and 3j exhibited promising antiamoebic activity (IC(50) = 0 05 mu M, 0 31 mu M, 006 mu M, 0 29 mu M) respectively than the standard drug metronidazole (IC(50) = 1 84 mu M). The toxicological studies of these compounds on human breast cancer MCF-7 cell line showed that all the compounds 3d, 3g, 3h, 3j and metronidazole were nontoxic at the concentration range of 1.56-50 mu M.
