crystal structure of aminoquinazoline 36 bound to Lck
OverviewOverview
The lymphocyte-specific kinase (Lck) is a cytoplasmic tyrosine kinase of, the Src family expressed in T cells and natural killer (NK) cells. Genetic, evidence in both mice and humans demonstrates that Lck kinase activity is, critical for signaling mediated by the T cell receptor (TCR), which leads, to normal T cell development and activation. Selective inhibition of Lck, is expected to offer a new therapy for the treatment of T-cell-mediated, autoimmune and inflammatory disease. Screening of our kinase-preferred, collection identified aminoquinazoline 1 as a potent, nonselective, inhibitor of Lck and T cell proliferation. In this report, we describe the, synthesis and structure-activity relationships of a series of novel, aminoquinazolines possessing in vitro mechanism-based potency. Optimized, orally bioavailable compounds 32 and 47 exhibit anti-inflammatory activity, (ED(50) of 22 and 11 mg/kg, respectively) in the anti-CD3-induced, production of interleukin-2 (IL-2) in mice.
