PTP1B-IN-2 是一种蛋白酪氨酸磷酸酶抑制剂，IC50=50 nM。

PTP1B-IN-2 is an effective protein tyrosine phosphatase 1B (PTP1B) inhibitor(IC50=50 nM).

PTP1B-IN-2 extends deep into the active site pocket, forming several hydrogen bonds and hydrophobic interactions with key residues of the catalytic site. PTP1B-IN-2 greatly enhances insulin-mediated IRβ phosphorylation at concentrations of 15 μM and 30 μM.

The PTP1B enzymatic assay, the total volume of 100 μL per well contains15 nM recombinant PTP1B protein, 2 mM p-nitrophenylphosphonic acid (pNPP), 1 mM dithiothreitol and 1 mM EDTA (pH 6.5). After 30 min incubation at 37℃, end the reaction by addition of 2.5 M NaOH. The hydrolysis product, pNP, is detected at the absorbance at 405 nm.
