Gentiana macrophylla Pall.:a review of the basic source,traditional use,chemical components,pharmacological activities and quality control

Gentiana macrophylla Pall.(G.macrophylla),whose genus and family belong to the Gentianaceae and Gentiana.The main distribution centers of G.macrophylla resources were the Loess Plateau and the eastern Qinghai-Tibet Plateau in China.G.macrophylla,as a traditional medicine,has a long history and was used in different ethnic medicines.Its roots were used in traditional Chinese medicine,which had the effect of anti-inflammatory,anti-rheumatism,antiviral,promote blood circulation,eliminate swelling and pain,while its flowers were used in traditional Mongolian medicine,which had the effect of removing“Xieriwusu”(“Xieriwusu”means rheumatism),antiviral,reducing swelling.From previous studies,it could be found that there were more than forty components isolated and identified from G.macrophylla.The main chemical components were iridoids,flavonoids,triterpenoids,steroids,phenylpropanoids,and alkaloids.Iridoid terpenoid components represented by gentiopicroside and Loganic acid were the main components of the root of G.macrophylla,which had anti-inflammatory,antioxidant,hepatoprotective,analgesic,antibacterial and promote gastrointestinal tract activities.The flower mainly contains isoorientin and isovitexin as the representative of flavonoids.They have anti-tumor,liver protection,heart protection,inhibition of acetylcholinesterase and inhibition of melanin.It could be seen from previous studies that the research on G.macrophylla was mainly focused on the root,and the flower was rarely studied.It was reported that the experimental data of the anti-inflammatory and anti-tumor effects of G.macrophylla flowers show that its curative effect was very good.Therefore,the flowers of the flower of G.macrophylla can be used as potential medicinal parts for research.Given that flavonoids are mostly found in flowers and exhibit a range of functions,it is possible to investigate the flowers in order to learn more about G.macrophylla’s potential medical benefits.Based on botanical books,Chinese classic texts,medical monographs and academic search engines(Google,Google Scholar,Web of Science,SciFinder,Pubmed,CNKI,Sci-hub,Elsevier and Wanfang),the data and information on G.macrophylla in the past 20 years are inquired and summarized comprehensively.The basic source,traditional use,chemical composition,biological activity,pharmacodynamics and quality control of G.macrophylla was systematically reviewed,in order to provide reliable basis for the subsequent development and utilization of G.macrophylla.

Activation of G551D-CFTR by Bicyclooctane Compounds Is cAMP-dependent and Exhibits Low Sensitivity to Thiazolidinone CFTR Inhibitor CFTRinh-172

The G551D-CFTR mutation causing cystic fibrosis(CF) results from a missense mutation at codon 551(G551D) in the gene encoding of the cystic fibrosis transmembrane conductance regulator(CFTR). The G551D mutation in CFTR results in a reduced functional channel but G551D-CFTR is appropriately inserted in the apical membrane. In previous studies we discovered a class of high-affinity bicyclooctane(BCO) G551D-CFTR activators(G551D_ BCOs) with K_d down to 1 μmol/L. In this study, we analyzed the pharmacological activation of G551D-CFTR by the G551D_ BCOs by means of short circuit current analysis and cell-based fluorescence quenching assay. The G551D_ BCOs-induced G551D-CFTR activation is cAMP-dependent and is less sensitive to thiazolidinone CFTR inhibitor CFTRinh-172. These data suggest that (1) the phosphorylation of G551D-CFTR by protein kinase A is required for the activation by G551D_ BCOs; (2) G551D_ BCOs and CFTRinh-172 may act at the same site on the G551D-CFTR molecule.

Plant Secondary Metabolites： Biosynthesis, Classification, Function and Pharmacological Properties

Secondary metabolites, also known as phytochemicals, natural products or plant constituents are responsible for medicinal properties of plants to which they belong. The role they play in the plant is not, to date, well known or understood, but it may be beyond the protection. Their classification is based on chemical structure, composition, their solubility in various solvents, or the pathway by which they are synthesized. The main classification system includes three major groups： terpenoids, alkaloids and phenolics. For each one, we find subclasses with complexity in structure. In this review, we deal with the description of second metabolites, their biosynthesis, function, and the current pharmacological findings. Natural products are an important source of drug candidates in pharmaceutical industry, more deeply we understand them, the easier it is for scientists to intervene in alleviating different kind of diseases. The recent references have been consulted for presenting updated information, but also showing the new potentialities of plant second metabolites in drug research and development.

Phytochemicals,pharmacological and ethnomedicinal studies of Artocarpus:A scoping review

This article aims to review the scientific data on phytochemical and pharmacological studies of Artocarpus collected from Malaysia as well as to highlight their usage as ethnomedicine worldwide.About 55 Artocarpus species are distributed worldwide and 32 of the Artocarpus species can be found in Malaysia.Artocarpus species are well known worldwide for their edible fruits such as Artocarpus heterophyllus(jackfruit),Artocarpus integer(chempedak),and Artocarpus communis(breadfruit).Aside from its edible fruits,the timber is valued for light constructions,crates,large canoes,and boats.The literature for this review was searched using the term‘Artocarpus’,‘Artocarpus Malaysia’,‘Artocarpus extracts’,‘Artocarpus traditional medicine’and‘Artocarpus ethnomedicine’from published books and scientific journals via various engines such as The Web of Science,PubMed,Science Direct,Scopus,Research Gate,and Google Scholar.The references cited from the retrieved articles were also scanned and cross-checked.All published studies on phytochemical and pharmacological activities of Malaysia’s Artocarpus species up to January 2021 were included in this review.Articles on phytochemical studies of Malaysia’s Artocarpus revealed the isolation of flavonoids as the major constituents.Research on pharmacological activities of the isolated phytochemicals showed that these compounds exhibited significant disease-linkedenzyme(tyrosinase,cholinesterase,glucosidase)inhibitors as well as antioxidant,anti-inflammatory,antimicrobial,and cytotoxic activities.The ethnomedicinal data gathered are useful to understand and prioritize Artocarpus species that can contribute to potent phytochemicals and possibly new drug leads.This review also provides valuable information for the future development of isolated compounds from Artocarpus species.

Quinones from Cordia species from 1972 to 2023:isolation,structural diversity and pharmacological activities

Plants of the genus Cordia(Boraginaceae family)are widely distributed in the tropical regions of America,Africa,and Asia.They are extensively used in folk medicine due to their rich medicinal properties.This review presents a comprehensive analysis of the isolation,structure,biogenesis,and biological properties of quinones from Cordia species reported from 1972 to 2023.Meroterpenoids were identified as the major quinones in most Cordia species and are reported as a chemotaxonomic markers of the Cordia.In addition to this property,quinones are reported to display a wider and broader spectrum of activities,are efficient scaffold in biological activity,compared to other classes of compounds reported in Cordia,hence our focus on the study of quinones reported from Cordia species.About 70 types of quinones have been isolated,while others have been identified by phytochemical screening or gas chromatography.Although the biosynthesis of quinones from Cordia species is not yet fully understood,previous reports suggest that they may be derived from geranyl pyrophosphate and an aromatic precursor unit,followed by oxidative cyclization of the allylic methyl group.Studies have demonstrated that quinones from this genus exhibit antifungal,larvicidal,antileishmanial,anti-inflammatory,antibiofilm,antimycobacterial,antioxidant,antimalarial,neuroinhibitory,and hemolytic activities.In addition,they have been shown to exhibit remarkable cytotoxic effects against several cancer cell lines which is likely related to their ability to inhibit electron transport as well as oxidative phosphorylation,and generate reactive oxygen species(ROS).Their biological activities indicate potential utility in the development of new drugs,especially as active components in drug-carrier systems,against a broad spectrum of pathogens and ailments.
