Isoform-specific phosphoinositide 3-kinase inhibitors from an arylmorpholine scaffold
摘要:
Phosphoinositide 3-kinases (PI3-Ks) are an ubiquitous class of signaling enzymes that regulate diverse cellular processes including growth, differentiation, and motility. Physiological roles of PI3-Ks have traditionally been assigned using two pharmacological inhibitors, LY294002 and wortmannin. Although these compounds are broadly specific for the PI3-K family, they show little selectivity among family members, and the development of isoform-specific inhibitors of these enzymes has been long anticipated. Herein, we prepare compounds from two classes of arylmorpholine PI3-K inhibitors and characterize their specificity against a comprehensive panel of targets within the PI3-K family. We identify multiplex inhibitors that potently inhibit distinct subsets of PI3-K isoforms, including the first selective inhibitor of p110beta/p110delta (IC50 p110beta = 0.13 muM, p110delta = 0.63 muM). We also identify trends that suggest certain PI3-K isoforms may be more sensitive to potent inhibition by arylmorpholines, thereby guiding future drug design based on this pharmacophore.

The present invention relates generally to phosphoinositide 3-kinases (PI3Ks), and more particularly to methods of inhibiting undesirable immune responses without inhibiting desired immune responses. In one embodiment, the invention provides methods of inhibiting an endogenous immune response stimulated by at least one endogenous factor without substantially inhibiting an exogenous immune response stimulated by at least one exogenous factor comprising administering an amount of a phosphoinositide 3-kinase delta (PI3Kδ) selective inhibitor effective to inhibit the endogenous immune response stimulated by endogenous factor without substantially inhibiting the exogenous immune response stimulated by the at least one exogenous factor.
