Kinase experiment: | IC50 values for inhibition of the PI3K is measured. PI-103 is used as the reference compound. The compounds (NSC781406) are tested in duplicate for 10 concentrations, 100 nM or 500 nM as the top concentration. All reagents are diluted in kinase buffer.Three-fold, ten-point serial compound (NSC781406) dilutions are performed in kinase buffer[1]. |
Cell experiment: | Cytotoxic effects are tested in the human lung adenocarcinoma cells A549, human colon cancer cells HCT-116, human breast cancer cells MDA-MB-231 and human hepatocellular carcinoma cells BEL-7404. These four tumor cells are diluted to a density of 40,000–50,000 cells/mL in logarithmic phase. After the cells are treated with compounds (NSC781406) for 72 h, MTT solution (5 mg/mL, 20 μL) is added another 4h at 37°C. IC50 values are determined by a nonlinear regression analysis[1]. |
Animal experiment: | Mice: NSC781406 is orally administered once a day 30 mg/kg for 14 consecutive days or with sorafenib at 50 mg/kg. The relative tumor volume to vehicle-treated control mice is monitored[1]. |

NSC 781406 is a dual inhibitor of PI3K and mammalian target of rapamycin (mTOR; IC50s = 2.0, 9.4, 2.7, 14, and 5.4 nM for PI3Kα, PI3Kβ, PI3Kγ, PI3Kδ, and mTOR, respectively).1 It inhibits cell growth in the NCI-60 panel of cancer cell lines (mean GI50 = 65 nM). NSC 781406 (30 mg/kg) reduces tumor volume in a BEL-7404 hepatic cancer mouse xenograft model.

CC-223, NSC781406, and BGT226 Exerts a Cytotoxic Effect Against Pancreatic Cancer Cells via mTOR Signaling
Front Pharmacol 2020 Nov 11;11:580407.PMID:33343350DOI:10.3389/fphar.2020.580407.
The mTOR signaling pathway is abnormally activated in pancreatic cancer and is related to tumor glucose metabolism. However, its specific regulation mechanism is still unclear. Therefore, this study aims to investigate whether Sestrin2 affects the glucose metabolism of pancreatic cancer by modulating mTOR signal and then affects its biological behavior. We have observed that l-leucine can promote the proliferation of pancreatic cancer cells and increase the expression of Sestrin2 and p-mTOR proteins. In order to further study the role of Sestrin2 and mTOR signaling in pancreatic cancer, we conducted Sestrin2 overexpression and mTOR pharmacological inhibition experiments. We found that Sestrin2 overexpression can increase glycolysis of pancreatic cancer cells and promote their proliferation. This effect can be eliminated by mTOR inhibitors. Finally, we found that Sestrin2 knockdown could inhibit the growth of pancreatic cancer in vivo. In conclusion, these findings suggest that Sestrin2 may promote the occurrence and development of pancreatic cancer through mTOR signaling.
Discovery of benzenesulfonamide derivatives as potent PI3K/mTOR dual inhibitors with in vivo efficacies against hepatocellular carcinoma
Bioorg Med Chem 2016 Mar 1;24(5):957-66.PMID:26819001DOI:10.1016/j.bmc.2016.01.008.
The phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway is related to cellular activities. Abnormalities of this signaling pathway were discovered in various cancers, including hepatocellular carcinoma (HCC). The PI3K/mTOR dual inhibitors were proposed to have enhanced antitumor efficacies by targeting multiple points of the signaling pathway. We synthesized a series of propynyl-substituted benzenesulfonamide derivatives as PI3K/mTOR dual inhibitors. Compound 7k (NSC781406) was identified as a highly potent dual inhibitor, which exhibited potent tumor growth inhibition in the hepatocellular carcinoma BEL-7404 xenograft model. Compound 7k may be a potential therapeutic drug candidate for HCC.
