It is a rich source of different vitamins, potassium, zinc and other nutrients. The main pharmaceutical benefits of bitter melon are “antiinflammatory”, “antioxidant activity”, “antimicrobial characteristic”, “anticancer activity”, and “antihelmintic activity”, “antidiabetic effects”, “antiinflammation activity” and “treat skin conditions”. Its fruit is the main part of the plant which has been used for medicinal and food purposes. The primary metabolites in bitter gourd are common sugars, chlorophyll and proteins while secondary metabolites are carotenoids, alkaloids, phenolics, curcubitane triterpenoids, saponins, etc. The present review aims to study and survey on the nearly up-to-date results and findings regarding the pharmaceutical advantages and health benefits of bitter melon in an organic life.","PeriodicalId":11101,"journal":{"name":"Current organic synthesis","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present review describes progress since 2013 in the organocatalysis transformations of unsaturated pyrazolones. Pyrazolones are prevalent structural motifs in a wide variety of natural products and drug or drug-like molecules. A series of nitrogen-containing pyrazolones exhibits anti-cancer, antimicrobial, anti-inflammatory, anticonvulsant, antidepressant, antidiabetic, and an-tipyretic activities. Especially, chiral spiro-cyclic pyrazolones are recognized as targets in nat-ural products and clinical pharmaceuticals. Organocatalytic systems are powerful and reliable approaches that allow us to build structurally complex molecules in an enantioselectively and diastereoselectively manner. Avoiding the use of transition metal catalysts, readily available bifunctional organocatalysts, and the performance of the reaction at ambient temperature are other advantages of these catalytic systems. Despite considerable progress in this field, it is still one of the challenging goals for chemists to make new biologically active heterocyclic molecules.","PeriodicalId":11101,"journal":{"name":"Current organic synthesis","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
