colchicines for an N-arylurea unit causes a great improvement in anticancerproperties. The most promising derivatives were compounds 6 (o-Cl) and 14 (o,o-di-F) as they were able to downregulate all the tested targets at a concentration below their IC50 values. Thus, the arylurea unit enhances the potential of colchicine as an anticancer agent.

A new synthesis of unsymmetrical dihydro triazine-2,4- diones has been accomplished, through the strategy of a base-induced fragmentation of urazole derivatives, followed by an intramolecular cyclisation. Treating substituted urazole derivatives with LDA resulted in fragmentation of the N–N bond generating an imine, which was trapped in an intramolecular fashion to give products in good to excellent

The present investigation reports the efficient multistep synthesis of 1-(1,3-dioxoisoindolin-2-yl)-3-aryl urea analogs (7a–f) in good yields. All the 1-(1,3-dioxoisoindolin-2-yl)-3-aryl urea analogs (7a–f) were characterized by spectroscopic techniques. Five among the six compounds were tested against 56 cancer cell lines at 10 µM as per the standard protocol. 1-(4-Bromophenyl)-3-(1,3-dioxoisoindolin-2-yl)urea

Two series of 6,7-disubstituted-4-phenoxyquinoline derivatives bearing 2,4-imidazolinedione/pyrazolone scaffold were designed, synthesized and evaluated for their c-Met kinase inhibition and cytotoxicity against HT-29, H460, A549, MKN-45, and U87MG cancer cell lines in vitro. The pharmacological data indicated that most of the tested compounds showed moderate to significant cytotoxicity and high selectivity against HT-29, H460 and A549 cancer cell lines as compared with foretinib. The SAR analyses indicated that compounds with halogen groups, especially trifluoromethyl groups at 2-position on the phenyl ring (moiety B) were more effective. In this study, a promising compound 17 (c-Met IC50 = 2.20 nM, a multi-target tyrosine kinase inhibitor) showed the most potent antitumor activities with IC50 values of 0.14 mu M, 0.18 mu M, 0.09 mu M, 0.03 mu M, and 1.06 mu M against HT-29, H460, A549, MKN-45, and U87MG cell lines, respectively.
