Synthesis, characterization, antiamoebic activity and cytotoxicity of novel 2-(quinolin-8-yloxy) acetohydrazones and their cyclized products (1,2,3-thiadiazole and 1,2,3-selenadiazole derivatives)
1,2,3-selenadiazole derivatives were synthesized by the cyclization of novel 2-(quinolin-8-yloxy) acetohydrazones. In vitro antiamoebic activity was performed against HM1: IMSS strain of Entamoeba histolytica. The results showed that all the 2-(quinolin-8-yloxy) acetohydrazones were more active than their cyclized products (1,2,3-thiadiazole and 1,2,3-selenadiazole derivatives). SAR showed that the

A series of aryl-1,2,3-selenadiazoles has been prepared, and their n.m.r. spectral parameters are recorded. The ranges of chemical shifts of the 5-proton due to meta- or para-substitution in the 4-aryl substituent are similar to those for the corresponding protons in the side-chains of substituted benzenes.
