1-(4-Hydroxy-2-methoxyphenyl)-3-(4-hydroxy-3-prenylphenyl), isolated from Broussonetia kazinoki, shows in vitro inhibition of protein tyrosine phosphatase 1B (PTP1B) with an IC50 of 13.00 μM. PTP1B is a negative regulator of insulin action and an important mediator in the pathogenesis of insulinresistance and non-insulin dependent diabetes mellitus. PTP1B is regarded as a significant target for type 2 diabetes[1].
