PTP1B-IN-36

PTP1B-IN-36 is a PTP1B inhibitor (IC₅₀ 0.70 μM) and a SHP2-E76K inhibitor (IC₅₀ 0.36 μM). PTP1B-IN-36 exhibits broad-spectrum inhibitory activity against PTP family enzymes, including TCPTP, SHP1-PTP, SHP2-PTP, and SHP1-WT. PTP1B-IN-36 shows anticancer activity against osteosarcoma. PTP1B-IN-36 can be used for research on osteosarcoma.

For research use only. We do not sell to patients.

In Vitro

Anti-cancerOthers

Anti-cancer

PTP1B-IN-36 (0.07-50.0 μM; 72 h) exhibits dose-dependent antiproliferative activity in U2OS human osteosarcoma cells with an IC₅₀ of 157.24 μM, which is significantly less potent than its enzymatic inhibition due to unfavorable physicochemical properties limiting membrane permeability^[1].

Others

PTP1B-IN-36 (Compound 5a) (50 μM; 20 min) exhibits broad-spectrum PTP inhibition, achieving greater than 90% inhibition of PTP1B, TCPTP, SHP2-PTP, SHP2-E76K, and SHP1-WT, with 77.05% inhibition of SHP1-PTP^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
