Administration of VPS34-IN1 to cells induces a rapid dose-dependent dispersal of a specific PtdIns(3)P-binding probe from endosome membranes, within 1min, without affecting the ability of class I PI3K to regulate Akt. It can also induce a rapid ~50-60% loss of SGK3 phosphorylation within 1min. VPS34-IN1 has no inhibition to the SGK2 isoform that does not possess a PtdIns(3)P-binding PX domain.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
