Overview

Information

GSK481 GSK481 is a RIP1(Receptor Interacting Protein Kinase1, RIPK1) inhibitor. Inhibition of RIP1 has been shown to hinder cell necrotic death.

Targets

RIP1

In vitro

GSK481 can inhibit RIP1 WT S166 phosphorylation in human vs mouse plasmids overexpressed in HEK293T cells. GSK481 has approximately equivalent RIP1 FP potencies against human and cynomolgus monkey RIP1 but was >100-fold less potent against nonprimate RIP.
