Picado, Alfredo published the artcileA chemical probe for dark kinase STK17B derives its potency and high selectivity through a unique P-loop conformation, Quality Control of 623-50-7, the main research area is human dark kinase STK17B probe selectivity P loop structure.
STK17B is a member of the death-associated protein kinase family and has been genetically linked to the development of diverse diseases. However, the role of STK17B in normal and disease pathol. is poorly defined. Here, we present the discovery of thieno[3,2-d] pyrimidine SGC-STK17B-1 (11s), a high-quality chem. probe for this understudied “”dark”” kinase. 11S is an ATP-competitive inhibitor that showed remarkable selectivity over other kinases including the closely related STK17A. X-ray crystallog. of 11s and related thieno[3,2-d]pyrimidines bound to STK17B revealed a unique P-loop conformation characterized by a salt bridge between R41 and the carboxylic acid of the inhibitor. Mol. dynamic simulations of STK17B revealed the flexibility of the P-loop and a wide range of R41 conformations available to the apo-protein. The isomeric thieno[2,3-d]pyrimidine SGC-STK17B-1N (19g) was identified as a neg. control compound The >100-fold lower activity of 19g on STK17B was attributed to the reduced basicity of its pyrimidine N1.
Journal of Medicinal Chemistry published new progress about Apoptosis. 623-50-7 belongs to class esters-buliding-blocks, name is Ethyl 2-hydroxyacetate, and the molecular formula is C4H8O3, Quality Control of 623-50-7.
