Description
IMR-1A, a acid metabolite of IMR-1, is a Notch inhibitor with an IC50 of 0.5 μM. IMR-1A has a 50-fold increase in potency with respect to IMR-1. IMR-1 can metabolize in vivo to IMR-1A.

How to use
In Vitro:
IMR-1A (2 mg/kg (i.v.) and 100 mg/kg (i.p)) exhibits low systematic plasma clearance (CL = 7 mL/min/kg) with terminal elimination half-life (T1/2) of 2.22 h following a single i.v. administration. The normal liver blood flow in mice is 90 mL/min/kg and the Vss (volume of distribution) is ~4-fold. Plasma concentrations is quantifiable up to 24 h with Tmax of 0.50 h after i.p. administration.
