title: Discovery of 2-((3-Amino-4-methylphenyl)amino)-N-(2-methyl-5-(3-(trifluoromethyl)benzamido)phenyl)-4-(methylamino)pyrimidine-5-carboxamide (CHMFL-ABL-053) as a Potent, Selective, and Orally Available BCR-ABL/SRC/p38 Kinase Inhibitor for Chronic Myeloid Leukemia.
abstract: Starting from a dihydropyrimidopyrimidine core scaffold based compound 27 (GNF-7), we discovered a highly potent (ABL1: IC50 of 70 nM) and selective (S score (1) = 0.02) BCR-ABL inhibitor 18a (CHMFL-ABL-053). Compound 18a did not exhibit apparent inhibitory activity against c-KIT kinase, which is the common target of currently clinically used BCR-ABL inhibitors. Through significant suppression of the BCR-ABL autophosphorylation (EC50 about 100 nM) and downstream mediators such as STAT5, Crkl, and ERK's phosphorylation, 18a inhibited the proliferation of CML cell lines K562 (GI50 = 14 nM), KU812 (GI50 = 25 nM), and MEG-01 (GI50 = 16 nM). A pharmacokinetic study revealed that 18a had over 4 h of half-life and 24% bioavailability in rats. A 50 mg/kg/day dosage treatment could almost completely suppress tumor progression in the K562 cells inoculated xenograft mouse model. As a potential useful drug candidate for CML, 18a is under extensive preclinical safety evaluation now.
