Description

General description

A potent insulin receptor kinase (IRK) activator and protein phosphotyrosine phosphatase inhibitor. Excellent insulin mimetic for in vitro and in vivo use (15 µg/kg). Inhibits in situ dephosphorylation of autophosphorylated insulin receptors with greater than 1000-fold potency over sodium orthovanadate. Arrests proliferation of neuroblastoma NB 41 and glioma C6 cells at the G₂/M transition of the cell cycle. Also reported to potently inhibit PTEN (IC₅₀ = 38 nM). The water content varies from lot to lot and is supplied on the label along with the lot-specific molecular weight.
