| | PKI-179 (hydrochloride) Usage And Synthesis |
| Description | PKI-179 is an orally bioavailable dual inhibitor of PI3K and mammalian target of rapamycin (mTOR). In an in vitro enzymatic assay, it potently inhibits PI3K (IC50s = 8, 24, 17, and 74 nM for isoforms α, β, δ, and γ, respectively), two common PI3Kα mutants, E545K and H1047R (IC50s = 14 and 11 nM, respectively), and mTOR (IC50 = 0.42 nM). PKI-179 is selective for PI3K and mTOR over a panel of 361 other kinases at IC50 values up to 50 μM, hERG (IC50 > 30 μM), and cytochrome P450 (CYP) isoforms (IC50s > 30 μM), but does have activity for CYP2C8 (IC50 = 3 μM). It inhibits proliferation through the Akt/mTOR signaling pathway in MDA-361 breast and PC3MM2 prostate cancer cell lines in vitro (IC50s = 22 and 29 nM, respectively) and inhibits tumor growth in an MDA-361 mouse xenograft model when used at a dose of 50 mg/kg. | | Uses | PKI-179 hydrochloride is a potent and orally active dual PI3K/mTOR inhibitor, with IC50s of 8 nM, 24 nM, 74 nM, 77 nM, and 0.42 nM for PI3K-α, PI3K-β, PI3K-γ, PI3K-δ and mTOR, respectively. PKI-179 hydrochloride also exhibits activity over E545K and H1047R, with IC50s of 14 nM and 11 nM, respectively. PKI-179 hydrochloride shows anti-tumor activity in vivo[1][2]. | | in vivo | PKI-179 (5-50 mg/kg; p.o. once daily for 40 days) inhibits the tumor growth and is well tolerated in nude mice bearing MDA-361 human breast cancer tumors[1].
PKI-179 (50 mg/kg; p.o.) results in good inhibition of PI3K signaling in nude mice bearing MDA361 tumor xenografts[1].
PKI-179 exhibits good oral bioavailability (98% in nude mouse, 46% in rat, 38% in monkey, and 61% in dog) and a high half-life (>60 min) [1]. | Animal Model: | Nude mice bearing MDA-361 human breast cancer tumors[1] | | Dosage: | 5, 10, 25, 50 mg/kg | | Administration: | I.p. every 3 days for 4 weeks | | Result: | Exhibited pronounced tumor growth arrest when dosed above 10 mg/kg.
No significant weight loss of tested animals was observed for all different dosages.
