TCS 401 is a selective inhibitor of protein-tyrosine phosphatase 1B (PTP1B) (Ki values are 0.29, 59, 560, 1100, > 2000, > 2000 and > 2000 μM for PTP1B, CD45 D1D2, PTPβ, PTPε D1, SHP-1, PTPα D1 and LAR D1D2 respectively).
Sodium stibogluconate (Stibogluconate trisodium nonahydrate) is a potent inhibitor of protein tyrosine phosphatase. Sodium stibogluconate inhibits 99% of SHP-1, SHP-2 and PTP1B activity at 10, 100, 100 μg/mL, respectively.
DPM-1001 is a potent, specific, orally bioavailable and non-competitive inhibitor of protein-tyrosine phosphatase (PTP1B) with an IC50 of 100 nM, an an analog of the specific PTP1B inhibitor trodusquemine (MSI-1436; IC50=600 nM). DPM-1001 has anti-diabetic property.
cyt-PTPε Inhibitor-1 is a potent cytosolic protein tyrosine phosphatase epsilon (cyt-PTPε) inhibitor, binds to the catalytic domain of cyt-PTPε, blocks c-Src activation (dephosphorylation of c-Src), and exhibits anti-osteoclastic activity.
JTT 551 is selective a protein tyrosine phosphatase 1B (PTP1B) inhibitor, with Kis of 0.22 μM and 9.3 μM for PTP1B and TCPTP (T-cell protein tyrosine phosphatase), respectively; JTT 551 can be used in the research of type 2 diabetes mellitus.
SC-43, a Sorafenib derivative, is a potent and orally active SHP-1 (PTPN6) agonist. SC-43 inhibits the phosphorylation of STAT3 and induces cell apoptosis. SC-43 has anti-fibrotic and anticancer effects.
