The coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome 2 (SARS-CoV-2), turned into a global pandemic, and there remains an urgent demand for specific/targeted drugs disease. 3C-like protease (3CLpro) is promising target developing anti-coronavirus drugs. Schisandra sphenanthera fruit well-known traditional Chinese medicine (TCM) with good antiviral activity. This study found that ethanolic extract displayed significant inhibitory effect against SARS-CoV-2 3CLpro. Forty-four compounds were identified in this using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). Combining molecular docking vitro experiments, we two epimeric 7,8-secolignans, rel-(1S,2R)-1-(3,4-dimethoxyphenyl)-2-methyl-3-oxobutyl-3,4-dimethoxybenzoate (2) rel-(1S,2S)-1-(3,4-dimethoxyphenyl)-2-methyl-3-oxobutyl-3,4-dimethoxybenzoate (4), potently inhibited 3CLpro IC50 values of 4.88 ± 0.60 μM 4.75 0.34 μM, respectively. Moreover, vivo experiments indicated 4 potent regulating inflammatory response preventing lung injury. Our findings indicate may emerge as inhibitors via inhibition anti-inflammatory mechanisms.

Hypertension, commonly known as high blood pressure, is a significant health issue that increases the risk of cardiovascular diseases, stroke, and renal failure. This condition broadly encompasses both primary secondary forms. Despite extensive research, underlying mechanisms systemic arterial hypertension-particularly hypertension, which has no identifiable cause affected by genetic lifestyle agents-remain complex not fully understood. Recent studies indicate an imbalance in gut microbiota, referred to dysbiosis, may promote affecting pressure regulation through metabolites such short-chain fatty acids trimethylamine N-oxide. Current antihypertensive medications face limitations, including resistance adherence issues, highlighting need for novel therapeutic approaches. Stem cell therapy, emerging field regenerative medicine, shows promise addressing these challenges. cells, with mesenchymal stem cells being prime example, have regenerative, anti-inflammatory, immunomodulatory properties. Emerging research indicates can modulate reduce inflammation, improve vascular health, potentially aiding management. Research shown positive impact on microbiota various disorders, suggesting their potential role treating hypertension. review synthesizes recent interactions between By offering thorough analysis current literature, it highlights key insights, uncovers critical gaps, identifies trends will inform guide future investigations this rapidly advancing field.
