生物活性:
PI3K/mTOR Inhibitor-1 is a potent, orally bioavailable dual PI3K/mTOR inhibitor with IC50s of 20/376/204/46 nM and 186 nM for PI3Kα/PI3Kβ/PI3Kγ/PI3Kδ and mTOR, respectively. Antitumor activity.

体内研究:
PI3K/mTOR Inhibitor-1 (Compound 26) produces 54.4% tumor growth inhibition (TGI) with daily oral doses of 3.75 mg/kg for 27 days. The 7.5 mg/kg group of PI3K/mTOR Inhibitor-1 displays more significant TGI (72.9%). All animals survive after 27-day treatment, whereas 15% weigh loss is observed in PI3K/mTOR Inhibitor-1, 7.5 mg/kg group.Animal Model:Balb/c nu/nu mice with HT-29 colorectal carcinoma xenograft mouse model carrying the PIK3CA P449T mutation
Dosage:3.75 and 7.5 mg/kg
Administration:Oral gavage daily for 27 days
Result:Tumor growth inhibition (TGI) was 54.4% and 72.9% for daily oral doses of 3.75 mg/kg and7.5 mg/kg for 27 days, respectively.

体外研究:
PI3K/mTOR Inhibitor-1 (Compound 26) also exhibits potent functional suppression of AKT phosphorylation (IC50=196 nM). PI3K/mTOR Inhibitor-1 (0.046-10 μM, 72 hours) exhibits excellent antiproliferative effects on a panel of cancer cells.
