In spite of the great success of immune checkpoint inhibitors in immune-oncology therapy, an urgent need still exists to identify alternative approaches to broaden the scope of therapeutic coverage. Hematopoietic progenitor kinase 1 (HPK1), also known as MAP4K1, functions as a negative regulator of activation signals generated by the T cell antigen receptor. Herein we report the discovery of novel Pyrazolopyridine Derivatives as selective inhibitors of HPK1. The structure-activity relationship campaign led to the discovery of compound , which has shown promising enzymatic and cellular potency with encouraging kinome selectivity. The outstanding pharmacokinetic profiles of in rats and monkeys supported further evaluations of its efficacy and safety in preclinical models.
