AS-252424 is a potent, selective and novel small-molecule PI3Kγ inhibitor (IC50= 30 nM)

PI3K (phosphatidylinositol-4,5-bisphosphate 3-kinase) is a family of enzymes involved in cellular functions such as cell growth, proliferation, differentiation, motility, survival and intracellular trafficking, which in turn are involved in cancer. It plays a key role in PI3K/Akt/mTOR pathway.

In THP-1 (human monocytic cell line), AS-252424 inhibited the phosphorylation of PKB/Akt due to MCP1 binding to the GPCR receptor CCR2 at lowest IC50 values of 0.4 μM. In primary monocytes and monocytic wild-type cell line THP-1, AS-252424 inhibited MCP-1-mediated chemotaxis in a concentration-dependent manner (IC50 value= 52 μM and 53 μM, respectively). [1] In Capan 1 and HPAF (pancreatic cancer cell lines), AS52424 specifically inhibited the cell proliferation. [2]

In a mouse model of thioglycollate-induced peritonitis, oral administration of AS-252424 at 10 mg/kg led to moderate reduction of neutrophil recruitment (35% ±14%). [1]
