In this study, we described a series of 2,8-diazaspiro[4.5]decan-1-one derivatives as selective TYK2/JAK1 inhibitors. Systematic exploration of the structure-activity relationship through the introduction of spirocyclic scaffolds based on the reported selective TYK2 inhibitor 14l led to the discovery of the superior derivative compound 48. Compound 48 showed excellent potency on TYK2/JAK1 kinases with IC50 values of 6 and 37 nM, respectively, and exhibited more than 23-fold selectivity for JAK2. Compound 48 also demonstrated excellent metabolic stability and more potent anti-inflammatory efficacy than tofacitinib in acute ulcerative colitis models. Moreover, the excellent anti-inflammatory effect of compound 48 was mediated by regulating the expression of related TYK2/JAK1-regulated genes, as well as the formation of Th1, Th2, and Th17 cells. Taken together, these findings suggest that compound 48 is a selective dual TYK2/JAK inhibitor, deserving to be developed as a clinical candidate.

Feline McDonough sarcoma (FMS)-like tyrosine kinase 3 (FLT3) is one of the most pursued targets in the treatment of acute myeloid leukaemia (AML) as its gene amplification and mutations, particularly internal tandem duplication (ITD), contribute to the pa

The covalent binding nature of irreversible kinase inhibitors potentially increases the severity of “off-target” toxicity. Based on our continual strategy of chemically tuning the Michael addition acceptors, herein, we further explore the relationship amo
