PTPN22-IN-1 (Compound L-1) (WT mice; intraperitoneally) significantly reduces MC38 tumor growth. PTPN22-IN-1 (syngeneic immunocompetent model; CT26 in Balb/c mice) shows similar antitumor effects.
Administration of L-l intraperitoneally at 10 mg/kg yielded an average AUC of 4.55 µM h and Cmax of 1.1 1 µM (Fig. 9d), which is more than twice of its Ki value.
