Scientists obtained samwinol from traditional Chinese Tibetan medicine by chromatography separation and investigated its effects on protecting cells against neurotoxicity caused by amyloid beta protein fragment. The results showed that samwinol increased cell viability, inhibited the production of reactive oxygen species, and suppressed ERK/AKT phosphorylation while promoting Nrf2/HO-1 signaling. Samwinol has significant anti-neuroinflammatory and antioxidant activities, suggesting its potential use for treating Alzheimer's disease. Further studies are needed to confirm its efficacy.
Researchers studied the effect of Dracocephalum heterophyllum Benth flavonoid (DHBF), a traditional medicine used to treat various disorders, on cardiomyocyte hypertrophy in cultured cells. Neonatal rat cardiomyocytes were cultured and hypertrophy was induced using angiotensin II (Ang II). Ang II treatment reduced cell viability and increased the expression of cardiac hypertrophy genes. DHBF treatment reversed these effects in a concentration-dependent manner and may be related to the release of nitric oxide and regulation of intracellular calcium concentration. This study demonstrates the potential of DHBF in treating cardiomyocyte hypertrophy.
