: A one-pot three/two-component reaction of 3-acetyl-coumarin (1), 4/3-anisaldehyde (2a,b) and malononitrile or 3-acetylcoumarin (1) and 2-(4/3-methoxybenzylidene)malononitrile (5a,b) in glacial acetic acid/ammonium acetate under reflux afforded 2-amino-4-(4/3-methoxyphenyl)-6-(2-oxo-2H-chromen-3- yl)nicotinonitrile (4a,b). Spectral data helped establish the structures of the compounds. Subsequently, an antiproliferative evaluation against a selected line of tumorous cells (HepG-2, MDA-MB-231 and A549) was performed in-vitro for the novel 2-amino-4-(4/3-methoxyphenyl)-6-(2-oxo-2H-chromen-3-yl)nicotinonitrile (4a,b). Compound 4a exhibited good efficiency against the MDA-MB-231 and A549 cell lines compared with the reference drug (Vinblastine). Furthermore, the chemical reactivity of both compounds was discussed using DFT. Lastly, a molecular docking analysis was addressed and conducted for these desired molecules.

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.

Inulin is a naturally occurring polydisperse and flexible polysaccharide. It is a non-toxic, biocompatible, water-soluble, biodegradable, and affordable polymer. Furthermore, because of its unique properties, inulin has piqued the interest of many researchers. Studies have revealed that inulin demonstrates a broad range of biological activities such as antioxidant, antifungal, antibacterial, anticancer, antidiabetic, and immunological modulating properties in the pharmaceutical industry. Inulin has been demonstrated to function as a sweetener, fat replacer, water-holding agent, thickener, texture modifier, and browning agent in dairy and bakery food items. Inulin has produced EMF, a biofuel that is one of the most desirable gasoline substitutes. Today, inulin is widely used in the chemical, food, and pharmaceutical industries. Chemical modification of inulin is an important methodology for expanding its applications in a variety of fields. This article discusses the numerous synthesis methods used to modify the inulin structure, including conventional and non-conventional methods such as microwave and ultrasonication, as well as the diverse applications of inulin and its derivatives in several industries. This review article seeks to explore the current state of research on synthetic modifications of inulin and its wide array of applications.

This study outlines the development of a novel approach utilizing microwave assistance for the alcohol dehydrogenative reaction. The process is catalyzed by manganese (II) and cobalt (II) in conjunction with chroman-4-one amino ligands. This research introduces a unique catalytic system capable of synthesizing various heterocyclic compounds, including pyrroles, pyridines, Betti bases, chromenes, and coumarins via alcohol dehydrogenation. The synthesis involved the preparation and characterization of a series of chroman-4-one amino ligands (C1-C6) using standard analytical techniques. These ligands, in combination with MnCl2‧4H2O and CoCl2, demonstrated remarkable catalytic activity, effectively driving alcohol dehydrogenation. The catalytic cycle was initiated by the in-situ formation of metal complexes with the ligands during the reaction. Characterization using ESI-MS confirmed the presence of metal complexes (Int-1) and other intermediates (Int-II and Int-III) throughout the catalytic cycle. Additionally, the controlled experiment corroborated the efficacy of the catalytic system, evidenced by the evolution of H2 gas.

: We have created novel 1,2,3-triazole-based benzothiazinone derivatives in the current work. The produced compounds' in vitro antioxidant, antifungal, and antitubercular properties were assessed. Moreover, a simulated molecular docking analysis was conducted on the cytochrome P450 lanosterol 14α-demethylase active site to elucidate the enzyme's binding affinity and interactions with synthesised benzothiazinone derivatives. A notable correlation between these compounds' antifungal activity and binding score was indicated by molecular docking data. The synthetic 1,2,3-triazole-based benzothiazinone derivatives may satisfy the structural criteria for creating novel antifungal drugs, according to the results of the in vitro and in silico investigations. result: The synthesized derivatives were evaluated for in vitro antifungal, Antitubercular and antioxidant activity. Furthermore, an in silico molecular docking study was performed against the active site of cytochrome P450 lanosterol 14α-demethylase to explicate the binding affinity and binding interactions of enzyme and synthesized benzothiazinone derivatives. Molecular docking data suggested a significant relationship between the binding score and antifungal activity for these molecules. The findings of the in vitro and in silico studies indicate that the synthesized 1,2,3-triazole-based benzothiazinone derivatives may meet the structural requirements for developing new antifungal agents.

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 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.
