The effective usage of the enhanced permeability and retention effect of a nanocarrier infused with the bioresponsive release mechanism of checkpoint inhibitors (aPD1 and aCTLA4) can become a boon to mankind. DNA nanococoons (DNCs) comprising cytosine-phosphorothioate-guanine oligodeoxynucleotides (CpG-ODNs) with potent immunostimulatory effects can significantly enhance anti-cancer activity. Triglycerylmonostearate (TGMS) with enzymatic cleavage potential at the wound sites of tumor resection, upon caging with restriction enzyme (HhaI) followed by attaching to DNCs, makes the immunotherapy bioresponsive. Hhal-TGMS-DNCs-aPD1 triggered by the inflammation at the wound site undergoes enzymatic cleavage, releases the restriction enzyme, converts DNCs to CpG ODNs sequentially and with sustained aPD1 release exerts an appreciable anti-cancer effect.</p>","PeriodicalId":20011,"journal":{"name":"Pharmaceutical patent analyst","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138047733","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}
