Some flavonoids exert anti-inflammatory effects through: Blockade of NF-κB, and NLRP3 inflammasome, inhibition of pro-inflammatory cytokine production, IL-1β, IL-2, IL-6, TNF-α, IL-17A, down regulation of chemokines, and reduction of reactive oxygen and nitrogen species. Nevertheless, several reports have shown that some flavonoids enhance immune response by enhancing: oxygen and nitrogen radicals, antibody production, cytotoxic activity against tumours by increasing activating receptors and down regulating inhibitory receptors. In consequence, flavonoids may be potentially useful for treatment of infectious diseases and cancer.\u0000\u0000\u0000CONCLUSION\u0000The most potent flavonoids in inflammation that modify immune responses are apigenin, quercetin and Epigallocatechin-3-Gallate (EGCG) although, other compounds are still under study and cannot be excluded. The most relevant patents concerning the use of flavones and other polyphenols were revised. A promising future of these compounds in different therapies is discussed.","PeriodicalId":20960,"journal":{"name":"Recent patents on inflammation & allergy drug discovery","volume":"13 2 1","pages":"84-104"},"PeriodicalIF":4.2,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2174/1872213X13666190426164124","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48443044","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}

It is frequently used in general anesthesia as a potent analgesic. It can be administered either orally, transdermally or systemically. Adverse effects due to opium alkaloids are usually because of a non-specific histamine release. Only in a few cases, a true allergy mechanism could be involved. Immediate reactions to opioids are most frequent than delayed reactions.

In addition, the relevant patents on therapeutic potential of apigenin have also been mentioned. METHODS Literature search was carried out using PubMed/Science, Google Scholar etc. which was further expended by the different combination of keywords: apigenin, inflammation, mechanism,therapeutic potential, cancer etc. Patent information was retrieved by searching the key terms: apigenin, inflammation, therapeutic potential from various databanks including Espacenet, Google patents, freepatent online and mendeley of WIPO, USPTO, SIPO, JPO, KIPO and EPO databases. CONCLUSION Studies related to the anti-inflammatory and anticancer potential of apigenin have been explored through this review article. Moreover, the patent analysis of apigenin has further strengthened its therapeutic role. Probing into the therapeutic properties of apigenin, further add value to this molecule in terms of its down regulation of major inflammatory and cancer associated signaling pathways. The article simultaneously would assist the scientific community to precisely understand the role of apigenin and design novel anti-cancer therapies.","PeriodicalId":20960,"journal":{"name":"Recent patents on inflammation & allergy drug discovery","volume":"1 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2174/1872213X13666190816160240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68048644","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}
