PHPS1 (Cat No.: R065983) is a selective small-molecule inhibitor of Src homology region 2 domain-containing phosphatase-2 (SHP2), a protein tyrosine phosphatase that regulates multiple signaling pathways downstream of growth factor receptors. By blocking SHP2 activity, PHPS1 suppresses RAS/MAPK and PI3K/AKT signaling, leading to reduced cell proliferation and survival. It is widely used as a research tool to study SHP2’s role in oncogenic signaling, immune regulation, and developmental biology. PHPS1 provides a valuable probe for validating SHP2 as a therapeutic target in cancer and immune-related diseases.
