SC-43 是一种具有口服活性的SHP-1 (PTPN6)激动剂。它是SoRafenib 的衍生物，可抑制STAT3的磷酸化并诱导细胞凋亡，具有抗纤维化和抗癌作用。

SC-43 is a potent and orally active agonist of SHP-1 (PTPN6). SC-43 inhibits the phosphorylation of STAT3 and induces cell apoptosis, and with anti-fibrotic and anticancer effects.

SC-43, a sorafenib derivative.SC-43-induced apoptosis in cholangiocarcinoma (CCA) via a novel mechanism.?Three CCA cell lines (HuCCT-1, KKU-100 and CGCCA) were treated with SC-43 to determine their sensitivity to SC-43-induced cell death and apoptosis.?SC-43 activated SH2 domain-containing phosphatase 1 (SHP-1) activity, leading to p-STAT3 and downstream cyclin B1 and Cdc2 downregulation, which induced G2-M arrest and apoptotic cell death.?Importantly, SC-43 augmented SHP-1 activity by direct binding to N-SH2 and relief of its autoinhibition.?Deletion of the N-SH2 domain (dN1) or point mutation (D61A) of SHP-1 counteracted the effect of SC-43-induced SHP-1 phosphatase activation and antiproliferation ability in CCA cells[1].

In vivo assay revealed that SC-43 exhibited xenograft tumor growth inhibition, p-STAT3 reduction and SHP-1 activity elevation[1].
