CATPB（Cat No.:I011328）is a selective inhibitor of the protein tyrosine phosphatase, PTP-B, which is involved in regulating cellular signaling pathways related to cell growth, differentiation, and immune responses. By inhibiting PTP-B activity, CATPB modulates various physiological processes, including inflammation, immune cell activation, and tumor progression. This compound shows promise for the treatment of autoimmune diseases, chronic inflammation, and certain cancers, where dysregulation of tyrosine phosphatases contributes to disease pathogenesis. Its targeted inhibition may help restore balance in immune function and prevent disease progression, offering potential therapeutic benefits.
