This can detrimentally impact the prognosis and quality of life of patients, potentially leading to the interruption of cancer chemotherapy and compromising cancer treatment. Recently, onco-cardiology (or cardio-oncology) has developed as a new interdisciplinary field that focuses on the prevention and treatment of cardiovascular toxicity of anticancer drugs. In this review, we explore the mechanism underlying the cardiotoxicity of anthracyclines and examine pharmacological agents that safeguard the heart from anthracycline-induced damage. Anthracycline-induced cardiotoxicity primarily involves oxidative stress, characterized by radical production in mitochondria and subsequent apoptosis in cardiomyocytes. While various antioxidant agents, such as resveratrol, vitamin E, and melatonin have demonstrated efficacy in reducing anthracycline-induced cardiotoxicity in animal models, their clinical effectiveness remains inconclusive. Alternatively, dexrazoxane, an intracellular iron chelator, along with standard heart failure medications, such as β-blockers, angiotensin-converting enzyme inhibitors, and angiotensin II receptor blockers, reduce anthracycline cardiotoxicity and prevent subsequent heart failure in both animal and human studies. Additionally, statins [hydroxymethylglutaryl (HMG)-CoA reductase inhibitors] and ranolazine have emerged as potential candidates for attenuating anthracycline-induced cardiotoxicity in clinical settings. Notably, recent in vitro findings suggest that everolimus, an autophagy/mitophagy-inducing antitumor drug, may protect cardiomyocytes from anthracycline-induced toxicity without reducing the antitumor effects of anthracycline. Although promising, further clinical research is warranted to validate the potential of everolimus as a safer and more effective anthracycline chemotherapeutic strategy.</p>","PeriodicalId":23810,"journal":{"name":"Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan","volume":"145 2","pages":"121-132"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phenyl mercuric acetate as the organomercury compounds was quantified by a direct thermal decomposition mercury analyzer accurately, precisely, and safely. The calibration curves for determining the level of phenyl mercuric acetate were shown to be linear in the range of 0.12-6.0 ng mercury (Hg). The quantitation limit (Hg: 4.7 ng/g) was adequately low relative to the regulation value (Hg: 1 µg/g). The modified method exhibited a recovery rate of phenyl mercuric acetate in various household products of 38-87% with relative standard deviations of 1.5-19.5% when the standard solution (60 ng Hg) was added to the samples (1.0 g).

Several tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) have been approved for metastatic RCC (mRCC). The current first-line treatment for mRCC involves combination therapies using TKIs and ICIs. However, there is no consensus on which TKI+ICI therapy is best or how to select the appropriate therapy for individual patients with RCC. The kidney expresses various metabolic enzymes, including CYP and uridine diphosphate glucose (UDP)-glucuronosyltransferase (UGT). Although information on CYP and UGT expression in the kidney is limited compared to our understanding of liver expression, the main CYP and UGT subtypes expressed at high levels in the kidney are estimated to be CYP2B6, CYP3A5, CYP4A11, CYP4F2, UGT1A6, UGT1A9, and UGT2B7. In RCC, the expression profiles and levels of these enzymes are somewhat altered compared with normal kidney. The main known subtypes of CYP and UGT in RCC are CYP1B1, CYP3A5, CYP4A11, UGT1A6, UGT1A9, UGT1A10, and UGT2B7. High CYP expression has been reported in several cancers, possibly conferring resistance to anti-cancer drugs including TKIs, due to extensive drug metabolism. Additionally, CYP and UGT expression levels may possibly affect cancer prognosis by metabolizing endogenous substrates, regardless of their role in anti-cancer drug metabolism. In this review, I discuss CYP and UGT expression level profiles in RCC based on previously published papers, including ours, and examine possible relationships between these enzyme expression profiles and treatment outcomes for patients with RCC.</p>","PeriodicalId":23810,"journal":{"name":"Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan","volume":"145 1","pages":"7-14"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
