Biological Activity

Description

WS6 is a β cell proliferation inducer via modulation of Erb3 binding protein-1 (EBP1) and the IκB kinase pathway.

Targets

EBP1 ^[1]

IκB kinase ^[1]

In vitro

WS6 induces R7T1 cell proliferation with EC50 of 0.28 μM, and promotes β cell proliferation in rodent and human primary islets. Both Erb3 binding protein-1 and the IκB kinase pathway are confirmed to function in the mechanism of action of WS6. ^[1]

In vivo

In RIP-DTA mouse model of β cell ablation, WS6 (50 mg/kg p.o.) ameliorates diabetes, and induces concomitant increases in β cell proliferation and β cell number. ^[1]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines R7T1 cells Concentrations ~10 μM Incubation Time 4 days Method R7T1 cells are growth-arrested by removal of doxycycline for 2 days and plated into 384-well plates at a density of 3,000 cells/well in growth medium. Β cell proliferation is assessed using CellTiter Glo after 4 days. Fold increase in cell number is calculated by normalizing compound-treated wells to the median of DMSO-treated wells.
