Biological Description

Chemical Properties

Storage & Solubility Information

Description	PI3Kα-IN-9 (compound 27) is a highly specific, orally active, and long-lasting inhibitor of PI3Kα, demonstrating potent inhibitory effects with IC50 values of 4.4, 128, 146, and 153 nM against PI3Kα, PI3Kγ, PI3Kδ, and PI3Kβ, respectively. Additionally, PI3Kα-IN-9 exhibits antiproliferative properties and effectively induces apoptosis. Given its characteristics, PI3Kα-IN-9 holds great potential for cancer research [1].
In vitro	PI3Kα-IN-9 (compound 27) demonstrated antiproliferative effects and induced apoptosis across various cancer cell lines, including gastric, ovarian, prostate, breast (with a focus on triple-negative), liver, multiple myeloma, chronic myeloid leukemia, glioma, and acute lymphoblastic leukemia, when administered at concentrations ranging from 0-8 μM over 72 hours. Specifically, in MGC-803 gastric cancer cells, PI3Kα-IN-9 reduced the expression of PI3Kα protein and its downstream proteins, p-AKT and p-P70S6 K. Cell viability assays showed that this compound inhibited the growth of these cancer cells, yielding IC 50 values between 0.43 to 1.33 μM. Further apoptosis analysis in MGC-803 cells revealed a dose-dependent increase in apoptotic cell percentage from 12.07% to 61.69% following treatment with varying concentrations of 0, 2, 4, and 8 μM over 36 hours.
In vivo	PI3Kα-IN-9 (compound 27) demonstrated favorable pharmacokinetics and therapeutic potential in preclinical studies. Administered to male Sprague-Dawley rats at doses of 1-10 mg/kg, either orally (p.o.) or intravenously (i.v.) for 24 hours, the compound exhibited notable stability (T 1/2 >10 h) and high bioavailability (130%) [1]. Further evaluation in male BALB/c nude mice at a dose of 30 mg/kg, administered orally once daily for 3 weeks, revealed its significant antitumor activity accompanied by minimal cytotoxicity [1]. The pharmacokinetic analysis in rats highlighted a dose-dependent increase in exposure, with parameters indicating efficient absorption and sustained plasma levels. In the tumor inhibition study with mice, the compound achieved a tumor growth inhibition (TGI) rate of 41.5%, underscoring its potential as a therapeutic agent with favorable pharmacokinetic properties and efficacy in cancer models.
