This natural substance has a high commercial value because it strengthens the heart and cerebral vessels and protects the nervous system and also reduces diabetes and diabetic complications. In addition, baicalein is known to decrease inflammatory markers such as IL-1β, IL-6 and TNF-α. In this review, we have attempted to compile the list of recent therapeutic patents of baicalein used for treating different disorders.","PeriodicalId":20011,"journal":{"name":"Pharmaceutical patent analyst","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42953257","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}

Quinidine is an anti-arrhythmic drug that functions as a moderately potent inhibitor of Slack channels; however, quinidine use is limited by its poor selectivity, safety and pharmacokinetic profile. Slack channels represent an interesting target for developing novel therapeutics for the treatment of malignant migrating partial seizures of infancy and other childhood epilepsies; thus, ongoing efforts are directed toward the discovery of small-molecules that inhibit Slack currents.
