Despite the promising potential of Boron Neutron Capture Therapy (BNCT), efficient and selective accumulation of boron-10 agents in cancer cells remains challenging. Conjugation of carborane with tumor-targeting ligands provides an alternative strategy for selective accumulation in the vicinity of cancer cells. In this study, we designed and synthesized aptamer-carborane derivatives, named AS1411-CB conjugates, via covalent linkage between a dodecahydro-arachno-bis(acetonitrile)decaborane and the DNA aptamer AS1411. AS1411 specifically binds to nucleolin, which is frequently overexpressed on the surface of cancer cells, thus enables selective targeting. Circular dichroism analysis indicated that AS1411-CB conjugates retained the characteristic G-quadruplex conformation of AS1411. Incorporation of a 5-Carboxyfluorescein (FAM) fluorescent label on AS1411 allowed flow cytometry analysis, which demonstrated significantly higher association of AS1411-CB conjugates with MCF-7 breast cancer cells compared with MCF-10 A normal mammary epithelial cells. Confocal microscopy further confirmed preferential localization of AS1411-CB conjugates on the surface of MCF-7 cells, consistent with nucleolin-mediated targeting. These results demonstrated that AS1411-CB conjugates preserved the targeting capability of AS1411 and highlighted its potential as a boron delivery platform for tumor-targeting applications.</p>","PeriodicalId":257,"journal":{"name":"Bioorganic Chemistry","volume":"182 ","pages":"110553"},"PeriodicalIF":5.1,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149014989","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}

Conventional chemical conjugation strategies not only suffer from poor regioselectivity-leading to high product heterogeneity and compromised bioactivity-but also frequently rely on toxic organic solvents and excessive coupling reagents, directly contradicting the principles of green chemistry. In contrast, biocatalysis has become an effective approach for precision bioconjugation. Operating under mild aqueous conditions, enzymatic transformations offer high regio- and chemoselectivity, high atom economy, and minimal environmental footprint. This review focuses on recent advances in the biocatalytic synthesis of functionalized biomacromolecules, covering four highly efficient green modification strategies: enzymatic glycosylation, lipidation, PEGylation, and macrocyclization. The catalytic mechanisms, substrate specificities, and structural engineering of diverse enzyme classes (e.g., transglutaminases, transpeptidases, ligases, and glycosyltransferases) are discussed in the context of generating homogeneous bioconjugates.

The design of the chimeric PPPT molecules integrated the biological potential of phthalazine, pyrrolidine, and triazole scaffolds using the Multiple Targeting Ligands (MTL) / molecular hybridization (MH) strategy, along with bioisosteric modifications of existing drugs. The synthesis of our chimeric PPPT derivatives was efficient and straightforward in two steps: a Huisgen 3 + 2 dipolar cycloaddition reaction of ylides with a symmetrically substituted cyclic Z-alkene, followed by a click copper-catalysed reaction. The cycloaddition reactions proceed with high stereospecificity, and NMR and single-crystal X-ray diffraction studies unambiguously established the stereochemistry of the obtained compounds. The anticancer assay reveals that the newly obtained compounds 1, 4a,b, and 6a-j have low or no cytotoxicity toward normal cells and exhibit very good to moderate activity against breast adenocarcinoma and osteosarcoma cancer cell lines. The most active compounds were proved to be the chimeric derivatives 6c, 6d, and 6j, with IC₅₀ values close to those of the standard drug doxorubicin on the MCF7 and MG-63 cancer cell lines, and with selectivity index values also indicating a good cytotoxic profile. Notable SAR correlations have been observed. The in silico Swiss-ADME evaluation indicates that our chimeric PPPT derivatives exhibit good ADME, drug-likeness, and medicinal chemistry properties. The in silico computational Swiss-Target Prediction tool predicts that our chimeric PPPT compounds will most likely act as Multiple Targeting Ligands, primarily as tyrosine kinase and PARP-1 inhibitors. The in silico molecular docking studies confirm VEGFR-2 and PARP-1 as possible binding sites for our compounds.

The multifactorial nature of AD, involving cholinergic deficits, amyloid-β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, mitochondrial dysfunction, neuroinflammation, and metal dyshomeostasis, has limited the clinical success of single-target therapeutic strategies. Although donepezil (DPZ), a clinically approved acetylcholinesterase (AChE) inhibitor, remains one of the most widely prescribed agents for symptomatic management, it does not alter the underlying neurodegenerative processes. Consequently, DPZ has emerged as an attractive medicinal chemistry scaffold for the development of multi-target-directed ligands (MTDLs) that simultaneously modulate multiple interconnected pathological pathways implicated in AD. This review provides a comprehensive and critically organized overview of recent advances in DPZ-based hybrid molecules, emphasizing rational design strategies, hybridization approaches, structure-activity relationships (SAR), molecular mechanisms, and pharmacological profiles. To facilitate a mechanistic understanding, the reported hybrids are systematically classified according to structural modifications of the indanone moiety, the benzylpiperidine moiety, or simultaneous modification of both pharmacophoric regions. Comparative analysis reveals how scaffold engineering, linker optimization, and strategic incorporation of complementary pharmacophores influence cholinesterase inhibition, anti-amyloid activity, antioxidant capacity, neuroprotection, metal chelation, monoamine oxidase inhibition, and blood-brain barrier permeability. Importantly, this review critically examines the current translational landscape, highlighting that despite encouraging in vitro and in vivo findings, no DPZ-based hybrid has yet advanced to clinical evaluation. Key challenges, including pharmacokinetic optimization, metabolic stability, safety, target engagement, and clinical translatability, are discussed together with future medicinal chemistry directions. Rather than presenting DPZ-based hybrids as established disease-modifying therapies, the available evidence supports their role as promising multifunctional lead compounds and valuable molecular platforms for the rational design of next-generation anti-Alzheimer agents. By integrating emerging SAR trends with critical translational perspectives, this review provides a contemporary framework to guide future development of clinically relevant multifunctional therapeutics for AD.</p>","PeriodicalId":257,"journal":{"name":"Bioorganic Chemistry","volume":"181 ","pages":"110361"},"PeriodicalIF":5.1,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148756742","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}
