Its high energy density, versatility, and compatibility with renewable energy sources make it an attractive option for power generation, transportation, and industrial decarbonization. However, significant challenges hinder its widespread adoption, particularly in storage and transportation. Due to its low volumetric energy density, hydrogen requires advanced storage solutions such as chemical carriers, metal hydrides, compressed gas, and liquid hydrogen, each presenting unique financial and technological challenges. Additionally, transportation infrastructure—including pipelines and hydrogen carriers—must be further developed to enhance efficiency, improve safety, and minimize energy losses. Overcoming these challenges is essential to establishing a global hydrogen economy. Advancements in cost reduction, infrastructure development, and innovative storage materials are key to making hydrogen a viable mainstream energy source. This review highlights the critical barriers to hydrogen storage and transportation, while emphasizing the importance of continuous research, technological innovation, and supportive policies in accelerating the adoption of hydrogen for a cleaner, more sustainable energy future.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"26 2","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145602598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a fused heterocyclic compound formed by the fusion of 1,3-thiazole and 1,2,4-triazole, and the type of ring fusion results in the formation of isomeric thiazolotriazoles—[3,2-b] or [2,3-c] isomers. The synthesis of both ring systems has been carried out by various methodologies ranging from conventional methods such as cyclization and annulation to the use of metal catalysts, microwave radiation, photochemical and multicomponent reactions. In drug discovery, thiazolotriazole derivatives have been primarily investigated for their antibacterial, anticancer, anti-inflammatory, and antifungal properties. Recent years have seen significant advancements in anticancer drug research, revealing that these molecules are potential anticancer agents interacting with specific targets or biochemical pathways responsible for apoptosis and proliferation. In addition, thiazolotriazole also exhibits analgesic, anticonvulsant, antidiabetic, and antioxidant activities. Furthermore, thiazolotriazoles have also demonstrated the potential to inhibit enzymes such as carbonic anhydrase, urease, cyclooxygenase, and butyrylcholinesterase, which are meant to have particular biological functions. In the context of various applications, a review that describes biological activities with a particular focus on structural attributes that contribute to the activity will be helpful to better understand structure–activity relationship (SAR) and guide for further design of bioactive thiazolotriazoles. This review explains the biological activity of thiazolotriazole highlighting SAR and drug targets for specific disease conditions which will be helpful to better understand the scaffold and apply this knowledge to future drug discovery on thiazolotriazoles.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"26 2","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145630270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They exhibit not only maximized atom utilization efficiency but also strong metal–substrate interactions that effectively modulate the electronic structure of metal centers. Furthermore, carbon substrates facilitate rapid electron transfer during biosensing processes and enhance the stability of single-atom sites. These advantages make CB-SANzymes highly promising for biosensing applications. This review examines the fundamental properties of CB-SANzymes and discusses strategies for their modifications. Key strategies include increasing single-atom density, tuning the coordination environment, leveraging multimetal synergy, and engineering carbon substrates via heteroatom doping and defect construction. We also summarize the recent advances of CB-SANzymes in diverse biosensing platforms, such as colorimetric, fluorescent, and electrochemical systems. Their contribution to enhancing the sensitivity, selectivity, and accuracy of these systems is emphasized.

This account highlights the use of norbornene derivatives as key building blocks in synthesizing various polyquinane scaffolds by employing advanced olefin metathesis (OM) strategies. Norbornene's reactivity is due to inherent strain energy and this reactivity promotes various synthetic transformations via ring-opening metathesis (ROM), ring-closing metathesis (RCM), and ring-rearrangement metathesis (RRM), enabling the precise bond reorganization that allows the construction of diverse linear, angular, and propellane types of polyquinane architects along with the higher order tetraquinanes and pentaquinanes. Diels–Alder adducts (DAA) derived from norbornene precursors further enhanced the modularity of these synthetic routes. Such approaches enabled an efficient assembly of cis–anti–cis and cis–syn–cis stereochemical motifs, overcoming challenges posed by strained ring systems and regioselective issues. Moreover, when the metathetic strategies are combined with Diels–Alder reaction (DAR), the complexity in the target molecules can rise quickly due to synergistic effect. These synthetic approaches efficiently construct tetraquinanes and pentaquinanes with intricate stereochemistry that allows the access of natural products and their analogs. These findings highlight the expanded use of alkene metathesis in constructing complex molecular architectures, emphasizing its crucial role in modern organic synthesis and drug development.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"25 12","pages":""},"PeriodicalIF":7.5,"publicationDate":"2025-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145676273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
