Catalog Number: 1819
Alternate Names: DAQ B1, L-783,281, DMAQ-B1
Chemical Name: 2-[2-(1,1-Dimethyl-2-propenyl)-1H-indol-3-yl]-3,6-dihydroxy-5-[7-(3-methyl-2-butenyl)-1H-indol-3-yl]-2,5-cyclohexadiene-1,4-dione
Biological Activity
Selective insulin receptor (IR) activator (EC50 values are 3 - 6 μM for IRTK and 100 μM for IGF1R and EGFR). Increases IR β subunit tyrosine phosphorylation and activation of PI 3-kinase and Akt, but not ERK. Induces glucose uptake in adipocytes and skeletal muscle in vitro, without enhancing vascular proliferation. Binds GAPDH. Also activates Trk by interacting at a site distinct from the neurotrophin-binding site.
