The discovery of click chemistry and bioorthogonal chemistry expanded their applications. Currently, they are extensively used in biology, biochemistry and medicine. For many years, aromatic azides were usually prepared using nucleophilic substitution. In this classical procedure, commercially available anilines are first converted into aryl diazonium salts which in turn are transformed into aromatic azides by nucleophilic substitution with sodium azide. However, this procedure is rather inconvenient experimentally since it requires the use of strong acids and low temperatures. In recent years, several alternative procedures have been developed. In the present review, we present the synthesis of aromatic azides by means of different experimental methodologies.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140581028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cartilage damage can result in the development of joint problems characterized by symptoms, such as pain, swelling, and osteoarthritis. Collagen scaffolds are extensively used as biomimetic substances for cartilage engineering due to their ability to offer structural, biochemical, and mechanical signals for chondrocytes. Nevertheless, traditional techniques for producing collagen scaffolds frequently yield inadequate pore architecture, diminished mechanical robustness, and restricted form accuracy. Hence, 3D printing is a developing method that can surpass these restrictions by allowing accurate manipulation of the shape, porousness, and makeup of the scaffold. 3D printing has the capability to include various materials and cells in the scaffolds, resulting in the production of intricate and personalized tissue structures. This research examines the latest progress in utilizing 3D printing to create collagen scaffolds for the purpose of regenerating cartilage. This text discusses the different sources of collagen, methods of cross-linking, techniques for printing, and strategies for post-processing that are employed to improve the performance of scaffolds. Furthermore, it discusses the difficulties and potential future paths of utilizing 3D printing to create collagen scaffolds for the purpose of regenerating cartilage.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140300813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technology provides high reproducibility and precise control over the fabricated constructs in an automated way. Chitosan is a naturalderived polysaccharide from chitin, found in the exoskeletons of crustaceans such as shrimp and crabs. Chitosan- based implants can be prepared using 3D bioprinting technology by depositing successive layers of chitosan- based bioink containing living cells and other biomaterials. The resulting implants can be designed to release drugs at a controlled rate over an extended period. The use of chitosan-based implants for drug delivery has several advantages over conventional drug delivery systems. Chitosan is biodegradable and biocompatible, so it can be safely used in vivo without causing any adverse effects. It is also non-immunogenic, meaning it does not elicit an immune response when implanted in vivo. Chitosan-based implants are also costeffective and can be prepared using simple techniques. 3D bioprinting is an emerging technology that has revolutionized the field of tissue engineering by enabling the fabrication of complex 3D structures with high precision and accuracy. It involves using computer-aided design (CAD) software to create a digital model of the desired structure, which is then translated into a physical object using a 3D printer. The printer deposits successive layers of bioink, which contains living cells and other biomaterials, to create a 3D structure that mimics the native tissue. One of the most promising applications of 3D bioprinting is developing drug delivery systems (DDSs) to administer several active substances, such as growth factors, proteins, and drug molecules. DDSs are designed to release drugs at a controlled rate over an extended period, which can improve therapeutic efficacy and reduce side effects. Chitosan-based implants have emerged as a promising candidate for DDSs due to their attractive properties, such as biodegradability, biocompatibility, low cost, and nonimmunogenicity. 3D bioprinting technology has emerged as a powerful tool for developing simultaneously controlled DDSs for administering several active substances. The rationale behind integrating 3D printing technology with chitosan-based scaffolds for drug delivery lies in the ability to produce customized, biocompatible, and precisely designed systems that enable targeted and controlled drug release. This novel methodology shows potential for advancing individualized healthcare, regenerative treatments, and the creation of cutting- edge drug delivery systems. This review highlights the potential applications of 3D bioprinting technology for preparing chitosan-based implants for drug delivery.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140166880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All synthesized compounds were characterized by using 1 H-NMR and 13C-NMR spectroscopies, FTIR, and elemental analysis techniques. One of the objectives of this study was the synthesis of Pd-NHC complexes with AChE/BChE inhibition activities. Among all the tested compounds, complexes 4b and 4c were found to have the most high potential AChE and BChE inhibitory activities with IC50 values of 21.57 ± 0.23 Mm and 15.78 ± 0.39 Mm, respectively. Conducting molecular docking studies helped us in gathering crucial information about the main binding interactions of inhibitors and enzymes, and the results were in agreement with the biological evaluation. The synthesized Pd-NHC complexes were employed for catalyzing the direct C2- and C5-arylation reaction between aryl (hetero) halide and a variety of heterocyclic systems. In both cases (C2 and C5-arylation), Pd-NHC complexes catalysts provided access to the arylated heterocycles in good to high yields in the presence of 1 mol% catalyst loading at 150 °C. The DFT theoretical investigation showed that the Pd-NHC complexes were of ML2X2 type, where the the Pd(II) cation had a square planar geometry. The interaction energies obtained by energy decomposition analysis (EDA) demonstrated that the 4d and 4e complexes were more stable in the presence of more methyl substituents. The chemical indicators demonstrated that the less stable 4c complex was more reactive in regard to the chemical hardness, chemical potential, and electrophilicity values.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140166876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
