Protein tyrosine phosphatases PTPN2 and PTPN1 (also known as PTP1B) have been implicated in a number of intracellular signaling pathways of immune cells. The inhibition of PTPN2 and PTPN1 has emerged as an attractive approach to sensitize T cell anti-tumor immunity. Two small molecule inhibitors have been entered the clinic. Here we report the design and development of compound , a novel small molecule PTPN2/N1 inhibitor demonstrating nanomolar inhibitory potency, good oral bioavailability, and robust antitumor efficacy.
