Mechanism of Action

Targets/IC₅₀/Ki	human RIP1 (Cell-free assay) 16 nM
In vitro	This compound has excellent activity in both RIP1 cellular systems, preventing TNF induced necrotic cell death, and an ulcerative colitis explant assay blocking spontaneous cytokine release.
In vivo	GSK2982772 exhibits approximately equivalent RIP1 FP potency against human and monkey RIP1 but was significantly less potent against nonprimate RIP1. This compound displays a good free fraction in blood in rats (4.2%), dogs (11%), cynomolgus monkeys (11%), and humans (7.4%). The inhibitor has a good pharmacokinetic profile across both rats and monkeys. It distributes into a range of tissues including the colon, liver, kidney, and heart at concentrations comparable to those of blood. However, it has low brain penetration in rat (4%) despite possessing good cell permeability, which is likely due to active extrusion of this chemical from the brain via the efflux drug transporter. It is predicted that this compound has high bioavailability, moderate to low clearance with a moderate volume, and a terminal half-life in the order of 12 h.
