IACS-13909 is a specific and potent allosteric inhibitor of SHP2 that suppresses signaling through the MAPK pathway. IACS-13909 potently impedes proliferation of tumors harboring a broad spectrum of activated RTKs as the oncogenic driver. IACS-13909 potently suppresses tumor cell proliferation in vitro.[1]
In EGFR-mutant osimertinib-resistant NSCLC models with EGFR-dependent and EGFR-independent resistance mechanisms, IACS-13909, administered as a single agent or in combination with osimertinib, causes tumor regression in vivo.[1]

Allosteric SHP2 Inhibitor, IACS-13909, Overcomes EGFR-Dependent and EGFR-Independent Resistance Mechanisms toward Osimertinib
Cancer Res 2020 Nov 1;80(21):4840-4853.PMID:32928921DOI:10.1158/0008-5472.CAN-20-1634.
Src homology 2 domain-containing phosphatase (SHP2) is a phosphatase that mediates signaling downstream of multiple receptor tyrosine kinases (RTK) and is required for full activation of the MAPK pathway. SHP2 inhibition has demonstrated tumor growth inhibition in RTK-activated cancers in preclinical studies. The long-term effectiveness of tyrosine kinase inhibitors such as the EGFR inhibitor (EGFRi), osimertinib, in non-small cell lung cancer (NSCLC) is limited by acquired resistance. Multiple clinically identified mechanisms underlie resistance to osimertinib, including mutations in EGFR that preclude drug binding as well as EGFR-independent activation of the MAPK pathway through alternate RTK (RTK-bypass). It has also been noted that frequently a tumor from a single patient harbors more than one resistance mechanism, and the plasticity between multiple resistance mechanisms could restrict the effectiveness of therapies targeting a single node of the oncogenic signaling network. Here, we report the discovery of IACS-13909, a specific and potent allosteric inhibitor of SHP2, that suppresses signaling through the MAPK pathway. IACS-13909 potently impeded proliferation of tumors harboring a broad spectrum of activated RTKs as the oncogenic driver. In EGFR-mutant osimertinib-resistant NSCLC models with EGFR-dependent and EGFR-independent resistance mechanisms, IACS-13909, administered as a single agent or in combination with osimertinib, potently suppressed tumor cell proliferation in vitro and caused tumor regression in vivo. Together, our findings provide preclinical evidence for using a SHP2 inhibitor as a therapeutic strategy in acquired EGFRi-resistant NSCLC. SIGNIFICANCE: These findings highlight the discovery of IACS-13909 as a potent, selective inhibitor of SHP2 with drug-like properties, and targeting SHP2 may serve as a therapeutic strategy to overcome tumor resistance to osimertinib.
miR-6071 inhibits hepatocellular carcinoma progression via targeting PTPN11
Arch Biochem Biophys 2022 Sep 30;727:109345.PMID:35792156DOI:10.1016/j.abb.2022.109345.
Hepatocellular carcinoma (HCC) is a deadly malignancy. Liver cancer stem cells (LCSCs) participated in HCC progression and caused failure of chemotherapy. However, the underlying mechanism for the LCSCs regulation was unclear. In this study, we found that miR-6071 expression was decreased in LCSCs. Gain-of-function assays showed that miR-6071 overexpression repressed LCSCs self-renewal and tumorigenesis and inhibited HCC cells proliferation and migration. In mechanism, bioinformatics and luciferase reporter assay demonstrated that miR-6071 targeted 3'UTR of PTPN11 mRNA. Pearson analysis revealed a negative correlation between miR-6071 expression and PTPN11 levels in HCC tissue samples. Further study showed that PTPN11 interference and specific inhibitors IACS-13909 abrogated the discrepancy of self-renewal ability, proliferation, migration and tumorigenicity capacity between miR-6071 overexpression HCC cells and control cells. Moreover, upregulation of miR-6071 sensitized HCC cells to lenvatinib treatment. Clinical cohort analysis revealed that HCC patients with high miR-6071 expression got more survival benefit from postoperative lenvatinib treatment than patients with low miR-6071 levels. In conclusion, our study demonstrated a regulation mechanism of LCSCs, a target against LSCSs, and a biomarker for postoperative lenvatinib treatment.
