Unfortunately, available drugs are far from ideal and no vaccines are available. Under these circumstances, new effective antileishmanial drugs with reduced host toxicity and improved dosing protocols are urgently needed. The sterol biosynthesis pathway (SBP) is a promising focus for combating Leishmania infections. Thus, various strategies have been documented, such as drug repurposing, combined therapy, rational drug design, and the use of synergistic effects to develop the metallodrugs that can act on essential parasite targets.Areas covered: This article reviews the critical enzymes participating in the ergostane-based sterol biosynthesis pathway (SBP) of Leishmania species, as well as recent progress in rational drug design, repurposing drugs, combined therapies, and the development of metallodrugs for use as antileishmanial agents. This review is based on literature searchers using SciFinder, Lens.org, Google Scholar, Web of Science, Pub Med, and DrugBank.Expert opinion: The limited focus on human leishmaniasis has resulted in a shortfall in effective treatments for this parasitic disease. The post-squalene segment of the sterol biosynthetic pathway is a promising target for treating Leishmania infections, particularly effective drugs or metallodrugs that inhibit the CYP51 or 24-SMT enzymes.","PeriodicalId":12267,"journal":{"name":"Expert Opinion on Drug Discovery","volume":" ","pages":"1031-1044"},"PeriodicalIF":4.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144616854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatment of tumors with TCEs has been clinically associated with toxicities related to cytokine release syndrome (CRS). In addition to clinical strategies to mitigate CRS, antibody engineering efforts have been undertaken to generate TCEs with optimized therapeutic index. Strategies pursued in this context include affinity attenuation of CD3 binding arm, to achieve potent tumor cell killing with minimal cytokine secretion.Areas covered: A literature search was conducted to identify peer-reviewed articles related to CD3 affinity and T cell engagers. Here, we provide an overview of the current state and recent developments in CD3 affinity-attenuation, both preclinically and clinically, with a focus on the challenges of developing TCEs with attenuated affinity to CD3 as well as identifying possible areas of improvement.Expert opinion: CD3 affinity reduction can effectively lower cytokine levels preclinically; however, it is crucial to consider all factors influencing the mode of action of TCEs.

It is a promising therapeutic approach for managing type 2 diabetes mellitus (T2DM).Research design and methods: Structure and Ligand-based screening approaches were employed to evaluate 1.1 million molecules for FFAR4 agonistic activity. Eight promising candidates were selected based on their binding affinity, non-bonded interactions, and pharmacokinetic properties and subjected to 500 ns molecular dynamics simulations (MDS). The therapeutic efficacy of compounds was assessed through in vitro assays, including cell viability tests, glucose uptake analysis, and gene expression profiling.Results: The analysis revealed several residues (VAL98, ARG99, ARG183, ARG22, ARG24, GLU43, and TRP305) that are essential for biological activity. Insights into the mechanistic contribution of amino acid residues located in the extracellular and intracellular loops of FFAR4 to ligand binding were obtained through MDS analysis. The binding energy values indicate a stronger binding affinity between the FFAR4 and hit molecules. In vitro experiments on selected compounds (Comp35, CompN1, CompN2, and diosmetin) confirmed their potential effects on insulin-stimulated glucose uptake, IR, inflammation, and diabetic pathways.Conclusions: Comp35, diosmetin, CompN1, and CompN2 were found to be potential hit agonists and can be developed for therapy.","PeriodicalId":12267,"journal":{"name":"Expert Opinion on Drug Discovery","volume":" ","pages":"1075-1092"},"PeriodicalIF":4.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144527107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research contents and conclusions of Co-IP in protein-protein interactions and protein-protein interaction modulators are summarized. Finally, three derivations of Co-IP assays are introduced. Literature was surveyed from original publications, standard sources, PubMed and clinical trials through 14 April 2025.Expert opinion: To perform Co-IP successfully, researchers must consider the selection of specific antibody, remission of nonspecific binding and detection limitations for transient or weak interactions. Co-IP assays offer several advantages over tandem affinity purification and pull-down methods, particularly in their applicability to primary cells. This allows for the study of PPIs in a natural cellular environment. Conventional Co-IP assays often struggle to detect weak or transient interactions and can suffer from nonspecific binding contamination. However, advancements in Co-IP techniques address these challenges, enhancing sensitivity and specificity, and enabling the detection of subtle interactions while distinguishing specific binding events. This makes Co-IP a powerful tool for exploring the dynamics of protein interactions in living systems.","PeriodicalId":12267,"journal":{"name":"Expert Opinion on Drug Discovery","volume":" ","pages":"859-872"},"PeriodicalIF":6.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143981022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, it gives an overview of the evolutionary history of antibiotic resistance genes and antibiotic biosynthesis genes/clusters, the structures of natural resistomes, and the regulatory roles of antibiotics.

Humans have also benefitted from access to, and the use of, a diverse range of antibiotics for many years also but have disrupted the balance by producing and using enormous amounts of antibiotics that have not existed before in natural ecosystems.
