Design, synthesis and biological evaluation of novel acrylamide analogues as inhibitors of BCR–ABL kinase
摘要:
A series of acrylamide analogues were designed and synthesized from Imatinib and Nilotinib as novel BCR-ABL inhibitors by application of the principle of nonclassical electronic isostere. All new compounds were evaluated for their inhibitory effects on the activity of BCR-ABL kinase and the proliferation of K562 leukemia cancer cells in vitro. The acrylamide analogues in which the substituent in C ring was trifluoromethyl group were identified as highly potent BCR-ABL kinase inhibitors. Compound 13f exhibited an IC50 value as low as 20.6 nM in ABL kinase inhibition and an IC50 value of 32.3 nM for antiproliferative activity, about 10.5-fold and 12-fold lower than those of Imatinib respectively. These results suggest that compound 13f is a promising candidate as a novel BCR-ABL kinase inhibitor for further development. (c) 2012 Elsevier Ltd. All rights reserved.

The activity of Pd(II)‐Schiffbasecomplex molecules grafted on the surface of Fe3O4@SiO2 particles were investigated in the palladium‐catalyzed couplingreactions of aryl halides with alkenes (Mizoroki‐Heck reaction) and phenylboronic acids (Suzuki‐Miyaura reaction) in the absence of phosphorous ligands. This method shows notable advantages such as heterogeneous nature of the catalyst, excellent yields
