RIPK1 inhibitor
Inhibition of RIPK1-mediated necroptosis using Necrostatin-1
Necrostatin-1 (Nec-1) is a potent and specific small-molecule inhibitor of receptor-interacting serine/threonine-protein kinase 1 (RIPK1, aka RIP1) [1, 2]. RIPK1, through its kinase and scaffolding functions, is a key regulator of apoptosis, necroptosis, and inflammatory pathways.

Mode of action:
Necrostatin-1 binds to a hydrophobic pocket of RIPK1, located between the N- and C-terminus of the kinase domain, and locks RIPK1 in an inactive conformation [3]. The Ser/Thr kinase activity of RIPK1 is essential for RIPK1-RIPK3-MLKL necrosome-mediated necroptosis upon TNF-α (tumor necrosis factor-α) signaling [2, 4]. Thus, Nec-1 acts as an inhibitor of RIPK1-mediated necroptosis. The administration of Nec-1 has been shown to reduce cell death and/or mortality in several disease models [4].
Key features:
- Potent and selective inhibitor of RIPK1
- Suppresses RIPK1-dependent necroptosis
- InvitroFit™ grade: each lot is highly pure (≥95%) and functionally tested for necroptosis inhibition
