PI3Kγ is one of four class I PI3Ks, a family of dual lipid and protein kinases involved in the regulation of numerous biological processes, such as cell growth, differentiation, survival, proliferation and migration1. A high-throughput chemoproteomics method has benen optimized to enable multiplexed screening resulting in the finding of CZC24832.
In vitro: Plenty of target- and cell-based studies of CZC24832 revealed regulation of interleukin-17–producing T helper cell (TH17) differentiation by PI3Kg, therefore giving selective inhibition of PI3Kg as a potential treatment for inflammatory and autoimmune diseases [1].
In vivo: CZC24832, the first selective inhibitor of phosphoinositide 3-kinase g (PI3Kg), was found to have efficacy in in vivo models of inflammation [1].
Clinical trial: Currenlty no clinical data are available.

Protokoll (Protocol)
Cell experiment: | RAW264.7 or THP-1 cells are starved for 2.5 h in serum-free medium before CZC24832 (0.1, 1, 10 and 100 μM) incubation for 30 min at 37°C. RAW264.7 cells are then stimulated for 3 min with C5a at a concentration of 0.6 μM, and THP-1 cells are stimulated with either insulin (1 uM, 10 min) or CSF (50 μg/mL, 5 min) at 37°C and lysed on ice. The detection of AKT phosphorylation (Ser473) is performed using the iBlot system[1]. |
Animal experiment: | Rats[1]Pharmacokinetics and oral bioavailability of CZC24832 are investigated in male Wistar rats following administration of a single intravenous (0.2 mg per kg body weight) or oral dose (10 mg per kg body weight). The dosing vehicle used is 0.5% (w/v) carboxymethyl cellulose in water for oral gavage. The intravenous dosing vehicle is 10% (v/v) DMSO in 30% (v/v) polyethylene glycol (PEG-400). Heparin blood for pharmacokinetic analysis is withdrawn retro-orbitally from mice or sublingually from rats to prepare plasma samples. These are homogenized with 10% (v/v) water and 3 volumes of acetonitrile and analyzed for CZC24832 by HPLC-MS/MS. |
