IPI-145

IPI-145 is a potent inhibitor of the phosphoinositide 3-kinase (PI3K) isoforms PI3Kgamma and PI3Kdelta (IC50s = 0.24 and 50 nM, respectively). It is orally bioavailable and selective. As PI3Kgamma and PI3Kdelta are preferentially expressed in immune cells, IPI-145 has profound effects in collagen-induced and adjuvant-induced arthritis, ovalbumin-induced asthma, and systemic lupus erythematosus animal models. It also has potential applications in immunotherapy and in certain cancers.Formal Name: 8-chloro-2-phenyl-3-[(1S)-1-(9H-purin-6-ylamino)ethyl]-1(2H)-isoquinolinone. CAS Number: 1201438-56-3.
