5IS5, 5ITD - PubMed Abstract:
Inhibition of the lipid kinase PI3Kδ is a promising principle to treat B and T cell driven inflammatory diseases. Using a scaffold deconstruction-reconstruction strategy, we identified 4-aryl quinazolines that were optimized into potent PI3Kδ isoform selective analogues with good pharmacokinetic properties. With compound 11, we illustrate that biochemical PI3Kδ inhibition translates into modulation of isoform-dependent immune cell function (human, rat, and mouse). After oral administration of compound 11 to rats, proximal PD markers are inhibited, and dose-dependent efficacy in a mechanistic plaque forming cell assay could be demonstrated.
