Rational design of 4-((6-phenoxypyrimidin-4-yl)amino)-N-(4-(piperazin-1-yl)phenyl)-1H-pyrazole-3-carboxamide (LT-540-717) as orally bioavailable FLT3 inhibitor
摘要:
we describe the discovery of compound LT-540-717 (32), a potent FLT3 inhibitor (IC50: 0.62 nM), starting from FN-1501. Compound 32 exhibited highly inhibitory activity against several acquired FLT3 mutations including FLT3 (ITD, D835V), FLT3 (ITD, F691L), FLT3 (D835Y) and FLT3 (D835V). Additionally, 32 displayed potentantiproliferativeactivity against FLT3-mutation driven BaF3 and AML cells. Oral administration

Cannabinoid CB1 receptors have been the avenue of extensive studies since the first clinical results of rimonabant (SR141716)for the treatment of obesity and obesity-related metabolic disorders were reported in 2001. To further evaluate the properties of CB receptors, we have designed and efficiently prepared a series of substituted pyrimidines based on chemical structure of Merck's taranabant, a cannabinoid CB1 receptor inverse agonist. Noticeably, N4-((2S,3S)-3-(3-bromophenyl)-4-(4-chlorophenyl)butan-2-yl)-N6-butylpyrimidine-4,6-diamine (13b) demonstrated good binding affinity and decent selectivity for CB1 receptor (IC50 = 16.3 nM, CB2/CB1 = 181.6).
