Background

IPI-145 (also known as INK1197), an isoquinolinone derivative, is a small-molecule phosphoinositide-3 kinases (PI3K) inhibitor that selectively and potently inhibits two PI3K isoforms, PI3K-δ and PI3K-γ, with half maximal inhibition concentration IC50 of 2.5 nM and 27 nM respectively. Despite of preference for PI3K-δ and PI3K-γ, IPI-145 also inhibits other PI3K isoforms, PI3K-α and PI3K-β, to a lesser extent with IC50 of 1602 nM and 85 nM respectively.

Due to the essential role of PI3K-δ in the proliferation of B cell and T cell, IPI-145 exhibits potent anti-proliferative activity against both cells with IC50 of 0.5 nM and 9.5 nM respectively leading to inhibition of neutrophil migration and basophil activation.

Inhibition of immune function through IPI-145-induced PI3K-δ and PI3K-γ blockade potentiates its application in the treatment of multiple inflammatory, autoimmune and hematologic diseases.
