Enhancement of kinase selectivity in a potent class of arylamide FMS inhibitors
摘要:
Structure-activity relationship (SAR) studies on a highly potent series of arylamide FMS inhibitors were carried out with the aim of improving FMS kinase selectivity, particularly over KIT. Potent compound 17r (FMS IC50 0.7 nM, FMS cell IC50 6.1 nM) was discovered that had good PK properties and a greater than fivefold improvement in selectivity for FMS over KIT kinase in a cellular assay relative to the previously reported clinical candidate 4. This improved selectivity was manifested in vivo by no observed decrease in circulating reticulocytes, a measure of bone safety, at the highest studied dose. Compound 17r was highly active in a mouse pharmacodynamic model and demonstrated disease-modifying effects in a dose-dependent manner in a strep cell wall-induced arthritis model of rheumatoid arthritis in rats.

The development of aerobic oxidative C–H/N–H cross-coupling catalyzed by the first-row transition metals is attractive yet challenging. Here, the first iron-catalyzed intramolecular cross-dehydrogenative coupling for the synthesis of carbazoles and indoles using air as the oxidant is reported. The general and efficient protocol allows for C–Nbondformation under green conditions with excellent functional
