using (1)H NMR, (13)C NMR, high resolution MS and melting points. Evaluation of antiproliferative activity of the benzimidazole analogues against MCF-7 and MDA-MB-231 revealed several compounds with unexpected selective inhibitions of MDA-MB-231 in micromolar range. All analogues were found inactive towards MCF-7. The most potent inhibition against MDA-MB-231 human breast cancer cell line came from the

A one-pot procedure for the synthesis of 4-arylidene-2-phenyl-5(4H)oxazolones directly fromarylaldehydebisulfiteadducts in the absence of Ac2O in good to excellent yields using phosphoryl chloride is reported. In addition, the observed chemoselectivity can be considered as a noteworthy advantage of this method.
A series of N-2-[2-(1H-benzimidazole-2-yl)phenoxy]ethyl} substituted amine derivatives were synthesized and tested for their cholinesterase inhibitor activity. Acetylcholinesterase and butyrylcholinesterase inhibitor activities were evaluated in vitro by using Ellman’s method. According to the activity results, all of the compounds displayed moderate acetylcholinesterase inhibitory activity and most
