Amentoflavone from Selaginella doederleinii reverses epithelial-mesenchymal transition in hepatocellular carcinoma by inhibiting core genes and blocking the p53 signaling pathway, leading to reduced cell migration, invasion, and apoptosis. Important for potential cancer treatment strategies.
SDTBE, a biflavonoid extract from Hieron, inhibits cervical cancer cell proliferation, induces apoptosis, autophagy, and cell cycle arrest, and suppresses tumor growth in mice. The mechanism involves activating the Caspase-dependent mitochondrial apoptosis pathway.
This study developed a new screening tool to find drugs to treat Alzheimer's disease by inhibiting acetylcholinesterase (AChE), an enzyme that deactivates the cognitive chemical acetylcholine. The researchers immobilized AChE on magnetic nanoparticles and optimized the process to maximize enzyme immobilization yield. They then used this tool to screen natural products and found four compounds that successfully inhibited AChE - one of which was more potent than the current treatment, tacrine. This approach could be useful for discovering target drugs from complex matrices.
