RESUMO

Berberine (BBR), a benzylisoquinoline alkaloid obtained from natural medicines such as coptidis rhizoma, has a wide range of pharmacological activities such as protecting the nervous system, protecting the cardiovascular system, anti-inflammatory, antidiabetic, antihyperlipidemic, antitumor, antibacterial, and antidiarrheal. However, factors such as poor solubility, low permeability, P-glycoprotein (P-gp) efflux, and hepatic-intestinal metabolism result in BBR having a low bioavailability (< 1%), which restricts its application in clinical settings. Therefore, improving its bioavailability is a prerequisite for its clinical applications. This review summarizes the various pharmacological effects of BBR and analyzes the main reasons for its poor bioavailability. It introduces methods to improve the bioavailability of BBR through the use of absorption enhancers and P-gp inhibitors, structural modification of BBR, and preparation of BBR salts and cocrystals as well as the development of new formulations and focuses on the bioavailability study of the new formulations of BBR. The research of BBR was also prospected in order to provide reference for the further research of BBR.

RESUMO

Natural plant-based medicines have gained in popularity, replacing artificial models and chemicals as a result of new pharmacological discoveries. The increased popularity and acceptability of herbal medications such as Commelina arose from the assumption that all-natural products are safe, readily available, and inexpensive. The genus Commelina (Commelinaceae), which has over 200 species, has long been utilized as a treatment for a variety of ailments and conditions around the world. However, to the authors' knowledge, there are no Comprehensive scientific reports of many medicinally important species of the genus Commelina under one roof. The current narrative review aims to present an updated overview of the various species of Commelina focusing on its morphology; geographical distribution; traditional medicinal use (species type, parts of the plant used, the mode of action, ailments treated, and countries practicing); phytochemical constituents; and pharmacological properties. The data search approach was carried out utilizing English-language electronic databases such as PubMed, Web of Science, Scopus, Science Direct, Research Gates, Ethnobotany Research and Applications, and Google Scholar. Using key terms such as "medicinal plant," "genus Commelina," "traditional medicinal usage of Commelina species," "photochemistry of Commelina species," and "pharmacological (biologic) activities of Commelina species" numerous searches and in-depth discussions are conducted. It was found that many Commelina species contain bioactive-phytochemicals (secondary metabolites) with a variety of structural kinds, including alkaloids, phenolics, flavonoids, glycosides, tannins, saponins, sterols, anthocyanins, and others which are presumed for their pharmacological activities. According to the invitro and preclinical reports, the Commelina species have shown anti-diabetic, antioxidant, anti-microbial, analgesic, anti-inflammatory, anti-cancer, hepato-protective, diuretic, fertility-inducing, anti-diarrheal, and anthelmintic activity, sedative, and anxiolytic activities. Although standardized extracts and phytochemicals derived from numerous Commelina species are presumed to provide safer alternatives for treating a variety of human ailments, the phytochemistry and pharmacology of the genus' plants have yet to be thoroughly investigated, both in preclinical studies with various animal models and in large-scale clinical trials. The authors also advocate for future collaboration among scientists, pharmaceutical firm owners, and other interested parties to develop novel commelina drugs.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Cordyceps has a long medicinal history as a nourishing herb in traditional Chinese medicine (TCM). Ischemic cardio-cerebrovascular diseases (CCVDs), including cerebral ischemic/reperfusion injury (CI/RI) and myocardial ischemic/reperfusion injury (MI/RI), are major contributors to mortality and disability in humans. Numerous studies have indicated that Cordyceps or its artificial substitutes have significant bioactivity on ischemic CCVDs, however, there is a lack of relevant reviews. AIM OF THE STUDY: This review was conducted to investigate the chemical elements, pharmacological effects, clinical application and drug safety of Cordycepson ischemic CCVDs. MATERIALS AND METHODS: A comprehensive search was conducted on the Web of Science, PubMed, Chinese National Knowledge Infrastructure (CNKI), and Wanfang databases using the keywords "Cordyceps", "Cerebral ischemic/reperfusion injury", and "Myocardial ischemic/reperfusion injury" or their synonyms. The retrieved literature was then categorized and summarized. RESULTS: The study findings indicated that Cordyceps and its bioactive components, including adenosine, cordycepin, mannitol, polysaccharide, and protein, have the potential to protect against CI/RI and MI/RI by improving blood perfusion, mitigating damage from reactive oxygen species, suppressing inflammation, preventing cellular apoptosis, and promoting tissue regeneration. Individually, Cordyceps could reduce neuronal excitatory toxicity and blood-brain barrier damage caused by cerebral ischemia. It can also significantly improve cardiac energy metabolism disorders and inhibit calcium overload caused by myocardial ischemia. Additionally, Cordyceps exerts a significant preventive or curative influence on the factors responsible for heart/brain ischemia, including hypertension, thrombosis, atherosclerosis, and arrhythmia. CONCLUSION: This study demonstrates Cordyceps' prospective efficacy and safety in the prevention or treatment of CI/RI and MI/RI, providing novel insights for managing ischemic CCVDs.
