Chitosan (CS) is a natural polymer obtained by removing acetyl groups from chitin through alkaline hydrolysis. It possesses biodegradable properties and exhibits immunological, antibacterial, and wound-healing activities. This polysaccharide has undergone modification through radiation-induced graft copolymerization to broaden its application scope. The potential applications of CS can be expanded by introducing side chains through grafting. This article aims to review the innovative alternatives of gamma-graft-copolymerized CS and, for the first time, comprehensively examines the current applications of CS derivatives in dye removal, metal adsorption, antibacterial interventions, biomedical practices, drug delivery systems, and tissue engineering.

: A simple synthetic method was performed to design a novel series of polycyclic systems consisting of a coumarin-pyrazole-thiazole skeleton linked with a completed thiazole ring via hydrazone linkage. The methodology depended on the cyclization of the active precursor 2-[(3-(2-oxo-2H-chromen-3-yl)-1-(4- phenylthiazol-2-yl)-1H-pyrazol-4-yl)methy-lene]hydrazine-1-carbothioamide (2) by its reaction with a series of α-halocarbonyl reagents under Hantzsch reaction conditions. The spectral and analytical data confirmed the structures of all the synthesized compounds. The target compounds were screened for their in vitro anticancer activity. The cytotoxic effects of obtained compound were screened against cancer cell lines (MCF-7, HepG2, and HCT116) using the standard SRB method. Furthermore, products 4, 5, and 7b were the most active against all cancer cell lines, compared with Doxorubicin. These bioactive products effectively suppress the growth of cancer cells by activating the cell death program through late apoptosis. In addition, products 4 and 5 arrested the cell cycle at the S and G2 phases, while product 7b has the ability to arrest the cell cycle at the G2 phase against all three cancer cells. The molecular docking of the products 4, 5, and 7b showed good binding affinities with Cyclin-dependent kinase 8 (CDK-8), while the ADMET prediction supported that these bioactive products can be promising anticancer agents.

The development of effective therapeutics to control the infections of drug-resistant bacterial strains is the thrust area in medicinal chemistry. The glycoconjugate containing O-antigenic oligosaccharide and a carrier protein linked through a linker can develop an antigen against gram-negative bacteria like Escherichia coli (E. coli), Shigella, Providencia, and Salmonella. Therefore, the chemical synthesis of glycoconjugate vaccine candidates against these bacterial strains is a growing demand of modern-day research. The synthesis of carbohydrate parts that are oligosaccharides is the most challenging. Significant developments in oligosaccharide synthesis have occurred over the past few decades. This review will focus on the chemical synthesis of different complex oligosaccharides related to different strains of E. coli. This review concludes with a summary of synthetic developments and prospects.

A modified solid-liquid halex reaction was developed in the presence of a robust phase transfer catalyst under microwave conditions. A fast, mild, and practical microwave-assisted synthesis of 2,3-difluoro-5- chloropyridine 3 starting from 2,3,5-trichlorpyridine 1 and spray-dried KF in polar aprotic solvent was developed. The addition of Tetrakis (piperidino) phosphonium chloride as phase transfer catalyst A was studied under microwave irritation (450W) and increased the yield and significantly reduced the reaction time in contrast to the conventional heating procedure. The highest reaction rate was observed at 5 wt% phase transfer phosphonium salt catalyst to 2,3,5-trichloropyridine 1.

: Joint degeneration is a possible outcome of rheumatoid arthritis, an inflammatory disorder that is chronic, systemic, and progressive. Andrographis paniculata is known to contain many phytoconstituents that have demonstrated therapeutic effects in terms of inflammation. However, the therapeutic actions of Andrographis paniculata are still not fully understood. The present study aims to better understand rheumatoid arthritis and its possible treatments through the identification of relevant targets and mechanisms. A total of 47 common targets were identified for andrographolide, while 38 common targets were found for neoandrographolide. Additionally, 53 common targets were discovered for 5-hydroxy-7-methoxy flavone. Furthermore, a screening process was carried out to identify 9 primary hubb targets for andrographolide, neoandrographolide, and 5-hydroxy-7-methoxy flavone. Twenty useful gene ontology (GO) terms and twenty important Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathways were found through the study of gene ontology and pathways. Molecular-docking analysis revealed that andrographolide had the highest binding efficacy (- 7.8) towards the Serine/threonine-protein kinase 2 (PIM2) target. On the other hand, neoandrographolide displayed the highest binding efficacy towards mitogen-activated protein kinase (MAPK1) and Interlukine-6 (IL6), with docking scores of (-9.0) and (-7.2), respectively. Furthermore, 5-hydroxy-7-methoxy flavone showed the highest docking score (-6.6) with Arachidonate 12-lipoxygenase (ALOX-12). The identification of numerous targets linked with various pathways in the treatment of Rheumatoid arthritis proves to be a helpful resource for future investigation into the mechanism and clinical applications of AP, NP, and 5H-flavone.

The identification of numerous targets linked with various pathways in the treatment of Rheumatoid arthritis proves to be a helpful resource for future investigation into the mechanism and clinical applications of AP, NP, and 5H-flavone.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":"16 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141547094","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}

: The synthesis of a series of multifunctionalized 4,5-diarylpyridazines via inverse electron-demand Diels-Alder reaction between highly oxygenated diarylacetylenes and unsubstituted 1,2,4,5-tetrazine was developed using polyalkoxybenzenes isolated from industrial essential oils as starting material. The reaction proceeded smoothly to afford combretastatin A-4 analogs with pyridazine linker in consistently high yield. In a phenotypic sea urchin embryo assay, diarylpyridazine with 3,4,5-trimethoxyphenyl and 3-amino-4- methoxyphenyl aryl rings was identified as a potent antimitotic microtubule-destabilizing compound.
