JAK INHIBITOR I Usage And Synthesis

Description

Pyridone 6 (457081-03-7) is a potent, ATP-competitive pan-JAK inhibitor. Inhibits 1, 2 and 3 (IC50=1, 5 and 15 nM respectively) as well as JAK family member Tyk2 (IC50=1 nM).1 Also tested against 21 other kinases with inhibition ranging from 130 nm to >10 mM. Inhibits IL2 and IL4-dependent proliferation of CTLL cells.1 Induces intermediate mesoderm differentiation from embryonic stem cells in a cocktail with LY-294002, CCG-1423 and retinoic acid.2 Potently inhibits STAT1, STAT5 and STAT6 phosphorylation and ameliorates allergic skin inflammation in a mouse model.3 Suppresses asthmatic responses in a mouse allergic asthma model.4

Uses

Pyridone 6 is a ATP-competitive JAK inhibitor in clinical development for the treatment of myeloproliferative neoplasms and B cell acute lymphoblastic leukemia.

Definition

ChEBI: 2-tert-butyl-9-fluoro-1,6-dihydrobenzo[h]imidazo[4,5-f]isoquinolin-7-one is an organic heterotetracyclic compound that is 1,6-dihydrobenzo[h]imidazo[4,5-f]isoquinolin-7-one bearing additional tert-butyl and fluoro substituents at positions 2 and 9 respectively. It has a role as an EC 2.7.10.2 (non-specific protein-tyrosine kinase) inhibitor. It is an organic heterotetracyclic compound and an organofluorine compound.
