Structurally, flavonoid class phytochemicals consist of C6-C3-C6 chemical structures with different substitution patterns and have drug-like nature. Morelloflavone is a biflavonoid class phytochemical found to be present abundantly in the Garcinia genus. Morelloflavone has been investigated in the scientific field for its numerous pharmacological activities. The present work aims to discuss the scientific progress of health beneficial aspects and pharmacological potential of morelloflavone in medicine.\u0000\u0000\u0000\u0000The purpose of this work is to provide scientific information about the biological potential and health beneficial effects of flavonoids in medicine with special reference to the morelloflavone. In this work, we have collected the scientific data of morelloflavone for the biological potential and pharmacological activities against different types of human illnesses with their mechanism of action from Google, Google Scholar, Science Direct and PubMed and analyzed. Further, the preventive role of morelloflavone against various types of human illnesses and the mechanism of action have also been discussed in the present work. This work will provide up-to-date information on the health beneficial aspects of morelloflavone in medicine for the prevention and treatment of human complications.\u0000\u0000\u0000\u0000Morelloflavone exhibited a wide-range of pharmacologic activity in regulating numerous kinds of human disorders. Present work revealed the health beneficial aspects and pharmacological activities of morelloflavone for the prevention and treatment of human disorders due to its anti-microbial, anti-plasmodial, anti-oxidant, anti-atherosclerosis, anti-inflammatory, anti-tumor anti-restenosis, anti-HIV, aphrodisiac, Alzheimer's disease and apoptotic potential in the medicine. Further, its biological potential on phospholipase A2, melanin, kallikreins, monoamine oxidase, aromatase, Eg5 Inhibition and proprotein convertases have been also analyzed in the present work. Analytical data signified the importance of modern analytical tools for the separation and isolation of morelloflavone in medicine.\u0000\u0000\u0000\u0000Present work revealed the detailed pharmacological activities of morelloflavone that can be utilized in the future for the development of new pharmacologic agents.\u0000","PeriodicalId":7951,"journal":{"name":"Anti-Infective Agents","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47849908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
