TMBIM6 antagonist-1 (BAX-inhibitor-1) is a bax inhibitor

Bimiralisib (PI3K-IN-2) is an orally bioavailable pan inhibitor of PI3K and inhibitor of the mTOR, with potential antineoplastic activity. PI3K-IN-2 inhibits the PI3K kinase isoforms alpha, beta, gamma and delta and, to a lesser extent, mTOR kinase, which may result in tumor cell apoptosis and growth inhibition in cells overexpressing PI3K/mTOR. Activation of the PI3K/mTOR pathway promotes cell growth, survival, and resistance to both chemotherapy and radiotherapy.

2-(Cyclohexylmethyl)-Plumbagin, a naphthoquinone derivative, exhibits selective cytotoxicity towards PANC-1 human pancreatic cancer cells under nutrient-deprived conditions—a situation akin to the pancreatic cancer tumor microenvironment—over those in nutrient-rich settings, with PC50 values of 0.11 and 47.2 µM, respectively. At a 1 µM concentration, it triggers apoptosis in PANC-1 cells. Furthermore, this compound specifically inhibits the phosphorylation of Akt and mammalian target of rapamycin (mTOR) in PANC-1 cells under nutrient scarcity. In a MiaPaCa-2 pancreatic cancer mouse xenograft model, it significantly reduces tumor volume and weight when administered at 50 and 250 µg/animal dosages five times weekly.
