Β-blockers are among the most widely used drugs in the treatment of hypertension and acute cardiovascular events. In addition to blocking the receptor sites for catecholamines, third-generation β-blockers with associated vasodilating properties, such as carvedilol and nebivolol, provide a broad spectrum of metabolic effects, including anti-inflammatory and antioxidant properties and a favorable impact on glucose and lipid metabolism. This review aims to report the impact of β-blockers on metabolic modulation based on available literature data. We present an overview of β-blockers and their pleiotropic properties, discuss mechanisms by which these drugs affect cellular metabolism and outline the future perspectives. The influence of β-blockers on glucose metabolism, insulin sensitivity, inflammation and oxidative stress is complex and varies depending on the specific β-blocker used, patient population and underlying health conditions. Recent evidence particularly highlights the potential role of vasodilatory and nitric oxide-mediated properties of nebivolol and carvedilol in improving glycemic control, insulin sensitivity, and lipid metabolism and mitigating oxidative stress and inflammation. It suggests that these drugs may be potential therapeutic options for patients with metabolic disorders, extending beyond their primary role in cardiovascular management.</p>","PeriodicalId":12491,"journal":{"name":"Frontiers in Pharmacology","volume":"15 ","pages":"1489657"},"PeriodicalIF":4.4,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11695285/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common drugs currently used to treat lung diseases are still chemical drugs, but this may lead to drug resistance and damage to healthy organs in the body.

Lipid peroxidation is caused by the disruption of redox homeostasis, accumulation of reactive oxygen species (ROS), depletion of glutathione (GSH), and inactivation of glutathione peroxidase 4 (GPX4). Lipid peroxidation is closely related to the occurrence and progression of respiratory diseases, including acute lung injury, asthma, pulmonary fibrosis, pulmonary hypertension, chronic obstructive pulmonary disease, and lung cancer.

An optimized version of alteplase, tenecteplase, has been developed by exchanging six amino acids to increase half-life, achieve higher fibrin selectivity and increase resistance to plasminogen activator inhibitor-1. Meanwhile, several products containing tenecteplase exist. The aim of this study was to compare the fibrinolytic activity and overall product quality of the 25 mg/vial presentation of tenecteplase originator Metalyse<sup>®</sup> (Boehringer Ingelheim Pharma GmbH and Co., KG, Ingelheim, Germany) to the 16 mg/vial formulation of the tenecteplase copy Mingfule<sup>®</sup> (CSPC Recomgen Pharmaceutical, Guangzhou, Co., Ltd.).</p><p><strong>Methods: </strong>We have systematically analyzed and evaluated the biochemical and fibrinolytic differences between Metalyse<sup>®</sup> and Mingfule<sup>®</sup> using a wide range of routine quality testing assays, supplemented by mass spectrometry analysis and surface plasmon resonance assays. Additional host cell protein quantification and clot lysis testing following plasmin incubation over time were performed.</p><p><strong>Results: </strong>Several key differences in biochemical composition and clot lysis activity were observed between the two tenecteplase variants. Versus Metalyse<sup>®</sup>, Mingfule<sup>®</sup> exhibited lower clot lysis activity and contained less of the two-chain form of tenecteplase. In addition, there were differences in sialic acid content, galactosylation, and fucosylation patterns, with Mingfule<sup>®</sup> exhibiting more bi- and less tri- and tetra-antennary glycosylation, leading to a different charge and size heterogeneity profile. Furthermore, Mingfule<sup>®</sup> displayed highly dissimilar binding to the three clearance receptors (LRP-1, ASGR, and mannose receptor) compared with Metalyse<sup>®</sup>. Purity analysis showed that Mingfule<sup>®</sup> contained a lower monomer content and, in contrast to Metalyse<sup>®</sup>, substantial amounts of host cell protein.</p><p><strong>Discussion: </strong>Taken together, these data demonstrate that the tenecteplase copy Mingfule<sup>®</sup> has several meaningful fibrinolytic and biochemical differences compared with Metalyse<sup>®</sup>. This raises the question of whether data from clinical studies with one of the products can be generalized for all tenecteplase variants.</p>","PeriodicalId":12491,"journal":{"name":"Frontiers in Pharmacology","volume":"15 ","pages":"1498116"},"PeriodicalIF":4.4,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11695638/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
