Beschreibung
Duvelisib (1201438-56-3) is a potent and selective (IC50’s: PI3Kα = 1602nM, PI3Kβ = 85nM, PI3Kδ= 2.5nM, PI3Kγ = 27nM) dual PI3Kδ/γ inhibitor.1 It inhibits B and T cell proliferation, blocks neutrophil migration, and inhibits basophil activation. Duvelisib antagonizes B-cell receptor cross-linking activated pro-survival signals in primary chronic lymphocytic leukemia cells.2?Duvelisib also shows preclinical/clinical activity against other hematologic malignancies such as Non-Hodgkins lymphoma, T-cell lymphoma, and others.3,4?Useful clinical agent for the treatment of various blood cancers. Low-dose treatment of T-cell-inflamed tumor models of head and neck cancers with Duvelisib enhanced responses to PD-L1 blockade via suppression of myeloid-derived suppressor cells.5?Higher doses reversed the effect due to suppression of tumor-infiltrating T lymphocytes
Verwenden
IPI 145 is an 1,2-dihydroisoquinolin-1(2H)-one derivative and has been developed as a modulator of PI3 kinase.
Definition
ChEBI: 8-chloro-2-phenyl-3-[(1S)-1-(7H-purin-6-ylamino)ethyl]-1-isoquinolinone is a member of isoquinolines.

Allgemeine Beschreibung
Class: lipid kinase; Treatment: CLL, SLL, FL; Other name: INK1197, IPI145; Oral bioavailability = 42%; Elimination half-life = 4.7 h; Protein binding = 98%
Pharmakokinetik
The recommended dose of duvelisib is 25 mg twice daily, much lower than that of idelalisib (150 mg, bid). Duvelisib is rapidly absorbed, with a peak concentration after 1–2 h. Following the administration of 25 mg of duvelisib, the absolute bioavailability in healthy volunteers is 42%. It is eliminated with a short half-life of 4.7 h, thus requiring twice daily administration.
target
PI3Kγ/δ
IC 50
Stoffwechsel
Duvelisib is primarily metabolized by CYP3A4 to give a monooxidation product, IPI-656, which has no pharmacologically relevant activity.
