- 靶點： Apitolisib (GDC-0980; GNE 390; RG 7422) is a selective, potent, orally bioavailable Class I PI3 kinase and mTOR kinase (TORC1/2)
- 體外研究： Apitolisib (GDC-0980) is remarkably selective for several other members of the closely related PIKK family kinases: C2alpha IC50=1300 nM; C2beta IC50=7 94 nM; VPS34 IC50=2000 nM; PI4Kalpha >10 μM; PI4Kbeta >10 μM; DNA-PK Kiapp=623 nM, respectively. A recent study shows that Apitolisib (GDC-0980) reduces cancer cell viability by inhibiting cell-cycle procession and inducing apoptosis with most potency in prostate (IC50 < 200="" nm="" 50%),=""><500 nm="" 100%),="" breast="" (ic50=""><200 nm="" 37%,=""><500 nm="" 78%)="" and="" nsclc="" lines="" (ic50=""><200 nm="" 29%,=""><500 nm="" 88%)="" and="" less="" potency="" in="" pancreatic="" (ic50=""><200 nm="" 13%,=""><500 nm="" 67%)="" and="" melanoma="" cell="" lines="" (ic50=""><200 nm="" 0%,=""><500 nm="" 33%).="">
- 體內(nèi)研究： Apitolisib (GDC-0980) (1 mg/kg, p.o.) demonstrats significant efficacy in mouse xenografts and is currently in phase I clinical trials for cancer. Clearance and PPB are low, and Apitolisib (GDC-0980) shows dose-proportional exposure from 5 mg/kg dosed in PEG to 50 mg/kg dosed in suspension in MCT, a finding attributed partially to the compound’s good solubility. Apitolisib (GDC-0980) (5 mg/kg, p.o.) results in greater than 50% TGI in 15 of the 20 xenograft models. The difference in tumor response to Apitolisib (GDC-0980) treatment correlates with the duration of knockdown of pAkt/tAkt.
