Beta-Sitosterol (SKF 14463) has recently been shown to induce G2/M arrest, endoreduplication, and apoptosis through the Bcl-2 and PI3K/Akt signaling pathways. Beta-Sitosterol (SKF 14463) , a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Although the exact mechanism of action of Beta-Sitosterol (SKF 14463) is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Beta-Sitosterol (SKF 14463) induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells.

CAY10406 is a trifluoromethyl analog of an isatin sulfonamide compound that selectively inhibits caspases 3 and 7. The non-trifluoromethyl compound exhibits Ki values of 1.2 nM and 6 nM for caspases 3 and 7, respectively. For all of the other caspases tested, it is 100 to 1,000 times less potent. Caspases 3 and 7 are 'effector caspases' that are downstream from the initiating steps of apoptosis, and are implicated in the main proteolytic processing of the apoptotic signal. No data is currently available for caspase inhibition by CAY10406.

CMLD-2 is an inhibitor of HuR-ARE interaction (Ki: 350 nM) that competitively binds HuR protein and disrupts its interaction with adenine element-rich (ARE) mRNA targets.CMLD-2 induces apoptosis and exhibits antitumor effects through MAD2 downregulation.
