PTPN22-IN-3
PTPN22-IN-3 is a potent, selective, and orally active inhibitor of PTPN22 with an IC50 of 0.49 μM and a Ki of 0.28 μM. PTPN22-IN-3 exhibits over 14-fold selectivity against a broad panel of PTPs and shows no significant inhibition against SRC/CSK kinases or IDO1/Arginase metalloenzymes. PTPN22-IN-3 enhances TCR signaling, increases IL-2 expression and secretion, and promotes mouse splenic T cell proliferation. In immune-competent C57BL/6J mice, PTPN22-IN-3 suppresses MC38 syngeneic tumor growth and synergizes with Pembrolizumab (anti-PD-1) (HY-P9902A) therapy. PTPN22-IN-3 can be used for the study of colorectal cancer and other solid tumors responsive to T cell-mediated anti-tumor immunity.

PTPN22-IN-3 (10 mg/kg; i.p.; once daily for 2 weeks) significantly inhibits MC38 tumor growth by approximately 53% in immune-competent C57BL/6J mice[1].
PTPN22-IN-3 (10 mg/kg; i.p.; once daily for ten consecutive days) shows no efficacy against MC38 tumor growth in immune-deficient NRG mice[1].
PTPN22-IN-3 (10 mg/kg; i.p.; twice daily for five consecutive days per week for 2 weeks) synergizes with Anti-Mouse PD-1 Antibody (RMP1-14, anti-PD-1) (HY-P99144) in MC38 tumor-bearing C57BL/6J mice[1].
PTPN22-IN-3 (10 mg/kg; i.p.; once daily for 2 weeks) in MC38 tumor-bearing C57BL/6J mice increases CD45+ immune cell infiltration, CD3+ T cell infiltration, CD4+ and CD8+ T cell populations, activates CD8+ T cells and NK cells (increased CD69 expression), and induces higher PD-1 expression on CD8+ T cells in the tumor microenvironment, consistent with a phenotypic shift associated with T cell activation[1].
