MedKoo CAT#: 406323

CAS#: 900185-02-6

Description: PIK-294 is a highly selective inihibitor of the phosphoinositide 3-kinase (PI3K) p110δ with an IC50 value of 10 nM compared to IC50 values of 10 μM, 490 nM and 160 nM for PI3Kα/β/γ, respectively. PIK-294 has been used to help distinguish the unique roles of the various PI3-K isoforms. PIK-294 inhibited both chemokinetic and chemotactic CXCL8-induced migration.
