GtoPdb Ligand ID: 10089

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: PN10 is a ponatinib/necrostatin hybrid molecule that inhibits RIPK1-driven necroptosis [1]. The compound retains most of ponatinib's in vivo activity, but with improved selectivity conferred by the necrostatin component.
