VX-745 Chemical Properties,Usage,Production

Description

VX-745 is an inhibitor of p38α MAPK (IC₅₀ = 9 nM). It is selective for p38α over p38β MAPK (K_i = 220 nM) as well as ERK, JNK, and a panel of 50 kinases when used at a concentration of 2 μM. VX-745 inhibits LPS-induced production of IL-1β and TNF-α in isolated human peripheral blood mononuclear cells (PBMCs; IC₅₀s = 45 and 51 nM, respectively). It reduces disease severity in a type II collagen-induced mouse model of arthritis when administered at a dose of 10 mg/kg.

Chemical Properties

Pale Yellow Solid

Uses

VX 745 is a potent and selective inhibitor of p38α mitogen-activated protein (MAP) kinase. VX 745 is a potential anti-inflammatory agents. Studies suggest that VX 745 may be useful in the treatment of Werner syndrome.

Definition

ChEBI: A member of the class of pyrimidopyridazines that is 6H-pyrimido[1,6-b]pyridazin-6-one substituted at positions 2 and 5 by (2,4-difluorophenyl)sulfanyl and 2,6-dichlorophenyl groups respectively

Biochem/physiol Actions

VX-745 is a selective blood-brain barrier penetrant inhibitor of p38 MAPKα. VX-745 showed 20-fold selectivity for p38α over p38β and a Ki value of 220 nM. VX-745 has been shown to reduce inflammation in an arthritic (AIA) mouse model and to improve performance in aged rats.
