Description

Description générale

A cell-permeable unsymmetrical bis-indolylquinone insulin mimic with anti-diabetic activity in animal models. Selectively stimulates insulin receptor (IR) tyrosine kinase activity (EC₅₀ ~ 6 µM in CHO•IR cells), while showing little effect towards IGF-1R, EGFR, or PDGFR. Also acts as an agonist for the neurotrophin receptors TrkA, B, and C in both cortical neurons and dorsal root ganglion neurons (~ 20 µM). DMAQ-B1 and insulin show differential effects on cellular gene expression profiles and DMAQ-B1 is a more selective agonist than insulin for the IR-mediated activation of PI-3 kinase/Akt pathway.
