ERK2/MAPK, another crucial cell signaling pathway protein, was also shown to play a crucial role in cell migration and proliferation. The complexes increase the ROS generation within the cell, further supporting apoptotic induction by exerting cellular oxidative stress. These metal complexes also affect ER stress by altering ERp29, an ER-resident chaperone, further inducing the process of apoptosis. The iridium(III) complexes restrict cervical cancer cell migration and proliferation by exerting pronounced effects as P53 activators and downregulation of ERK2/MAPK activity in cervical cancer cells. The underpinning mechanism of P53 and ERK2/MAPK activity in cervical cancer cells in the presence of iridium(III) complexes was studied in detail in this study, which paves the way for developing promising avenues for cancer therapeutics.","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epidemiological studies indicate that hyperuricemia is closely associated with the occurrence of various diseases such as gout and cardiovascular diseases. Currently, the first-line therapeutic medications used to reduce UA levels primarily include xanthine oxidase (XO) inhibitors, which limit UA production, and urate transporter 1 (URAT1) inhibitors, which decrease urate reabsorption and enhance urate excretion. Despite significant progress in urate-lowering therapies, long-term use of these drugs can cause hepatorenal toxicity as well as cardiovascular complications. Therefore, there is an urgent need for novel anti-hyperuricemic agents with better efficacy and lower toxicity. This perspective mainly focuses on the current research progress and design strategy of anti-hyperuricemic agents, particularly those targeting XO and URAT1.
