Abstract
In present investigation a series of 20 dioxazole analogues (1-20) were synthesized, characterized and subjected to molecular properties prediction, anti-amoebic screening and cytotoxicity evaluation. Out of the twenty compounds viz. 3,5-substituted-1,4,2-dioxazoles, six compounds have shown IC50 values in the range (1.00-1.10 mu M) lower than the standard drug metronidazole (IC50 = 1.45 mu M). The toxicological studies of the active compounds on H9c2 rat cardiac myoblasts showed that all compounds were nontoxic. The pKa, and log P values have also been predicted. Compound 8 showed the most promising results based on anti-amoebic evaluation, cytotoxicity studies and physico-chemical properties prediction. (C) 2011 Elsevier Masson SAS. All rights reserved.
