Optimization of 2-Phenylaminoimidazo[4,5-h]isoquinolin-9-ones: Orally Active Inhibitors of lck Kinase
摘要:
The tyrosine kinase p56lck (lck) is essential for T cell activation; thus, inhibitors of lck have potential utility as autoimmune agents. Our initial disclosure of a new class of lck inhibitors based on the phenylaminoimidazoisoquinolin-9-one showed reasonable cellular activity but did not work in vivo upon oral administration. Our current work highlights the further use of rational drug design and molecular modeling to produce a series of lck inhibitors that demonstrate cellular activity below 100 nM and are as efficacious as cyclosporin A in an in vivo mouse model of anti-CD3-induced IL-2 production.
Isoquinolinone synthesis by SNAr reaction: a versatile route to imidazo[4,5-h]isoquinolin-9-ones
摘要:
Reaction of 2-chlorobenzonitriles with beta-ketoesters in an SNAr reaction, followed by cyclization in acid provides a versatile route to isoquinolones. Starting from 2,6-dichloro-3-nitrobenzonitrile 7, sequential displacement of the chlorines by an amine and a beta-ketoester leads to imidazo[4,5-h]isoquinolin-9-ones 1, a new class of kinase inhibitor.
