Discovery of novel PI3-Kinase δ specific inhibitors for the treatment of rheumatoid arthritis: Taming CYP3A4 time-dependent inhibition

PI3Kδis a lipid kinase and a member of a larger family of enzymes, PI3K class IA(α, β, δ) and IB (γ), which catalyze the phosphorylation of PIP2 to PIP3. PI3Kδ is mainly expressed in leukocytes, where it plays a critical, nonredundant role in B cell receptor mediated signaling and provides an attractive opportunity to treat diseases where B cell activity is essential, e.g., rheumatoid arthritis. We report the discovery of novel, potent, and selective PI3Kδinhibitors and describe a structural hypothesis for isoform (α, β γ?) selectivity gained from interactions in the affinity pocket. The critical component of our initial pharmacophore for isoform selectivity was strongly associated with CYP3A4 time-dependent inhibition (TDI). We describe a variety of strategies and methods for monitoring and attenuating TDI. Ultimately, a structure-based design approach was employed to identify a suitable structural replacement for further optimization.

THIENOPYRIMIDIENE DERIVATIVES AS PI3K INHIBITORS

Thienopyrimidines of formula (I) wherein W and R1 to R4 are as defined in the claims, and the pharmaceutically acceptable salts thereof are inhibitors of PI3K and are selective for the p110δ isoform, which is a class Ia PI3 kinase, over both other class Ia and class Ib kinases. The compounds may be used to treat diseases and disorders arising from abnormal cell growth, function or behaviour associated with PI3 kinase such as cancer, immune disorders, cardiovascular disease, viral infection, inflammation, metabolism/endocrine function disorders and neurological disorders.

PURINE DERIVATIVES USEFUL AS PI3 KINASE INHIBITORS

This invention provides a compound which is a purine of formula (Ia) or (Ib): and the pharmaceutically acceptable salts thereof that are inhibitors of PI3K and a selective for the p110δ isoform, which is a class Ia PI3 kinase, over other class Ia PI3 kinases and over class Ib kinases. The compounds may be used to treat diseases and disorders arisi from abnormal cell growth, function or behaviour associated with PI3 kinase such as cance immune disorders, cardiovascular disease, viral infection, inflammation, metabolism/endocrine function disorders and neurological disorders.
