Crystal structure of TYK2 kinase with compound 19
Structural highlights
DiseaseTYK2_HUMAN Mendelian susceptibility to mycobacterial diseases;Autosomal recessive hyper IgE syndrome. Defects in TYK2 are the cause of protein-tyrosine kinase 2 deficiency (TYK2 deficiency) [MIM:611521; also known as autosomal recessive hyper-IgE syndrome (HIES) with atypical mycobacteriosis. TYK2 deficiency consists of a primary immunodeficiency characterized by recurrent skin abscesses, pneumonia, and highly elevated serum IgE. FunctionTYK2_HUMAN Probably involved in intracellular signal transduction by being involved in the initiation of type I IFN signaling. Phosphorylates the interferon-alpha/beta receptor alpha chain.[1] Publication Abstract from PubMedHerein, we disclose a new series of TYK2/ JAK1 inhibitors based upon a 3.1.0 azabicyclic substituted pyrimidine scaffold. We illustrate the use of structure-based drug design for the initial design and subsequent optimization of this series of compounds. One advanced example 19 met program objectives for potency, selectivity and ADME, and demonstrated oral activity in the adjuvant-induced arthritis rat model. Design and optimization of a series of 4-(3-azabicyclo[3.1.0]hexan-3-yl)pyrimidin-2-amines: Dual inhibitors of TYK2 and JAK1.,Fensome A, Ambler CM, Arnold E, Banker ME, Clark JD, Dowty ME, Efremov IV, Flick A, Gerstenberger BS, Gifford RS, Gopalsamy A, Hegen M, Jussif J, Limburg DC, Lin TH, Pierce BS, Sharma R, Trujillo JI, Vajdos FF, Vincent F, Wan ZK, Xing L, Yang X, Yang X Bioorg Med Chem. 2020 May 15;28(10):115481. doi: 10.1016/j.bmc.2020.115481.
