Polyphenols present in various plant and vegetable extracts possess enormous antioxidant, anti-inflammatory, anti-carcinogenic and anti-atherogenic qualities providing medical benefits. Antioxidants scavenge free radicals and other reactive oxygen species (ROS) by interrupting their mechanism of oxidation. Since free radicals cause neurological illnesses, cancer, heart disease, diabetes, atherosclerosis, and lipid and DNA damage, inhibiting their formation has recently been the subject of several medical investigations. Present studies described the determination of total phenolic content and DPPH activity of a large number of commonly used plant and vegetable extracts utilizing Folin-Ciocalte and Soler-Rivas procedures. This study aims to conduct a biochemical analysis of the therapeutic effects of okra, tamarind, and other phenolic compounds. The comparative data provided in this work for antioxidant and polyphenolic substances is expected to be highly valuable for readers who are interested in this subject.
存在于各种植物和蔬菜提取物中的多酚具有巨大的抗氧化、消炎、抗癌和抗动脉粥样硬化作用，可提供医疗益处。抗氧化剂通过干扰自由基和其他活性氧（ROS）的氧化机制来清除它们。由于自由基会导致神经系统疾病、癌症、心脏病、糖尿病、动脉粥样硬化以及脂质和 DNA 损伤，因此抑制自由基的形成最近已成为多项医学研究的主题。目前的研究利用 Folin-Ciocalte 和 Soler-Rivas 程序测定了大量常用植物和蔬菜提取物的总酚含量和 DPPH 活性。本研究旨在对秋葵、罗望子和其他酚类化合物的治疗效果进行生化分析。本研究中提供的抗氧化剂和多酚类物质的比较数据预计对对这一主题感兴趣的读者非常有价值。

The 4-thiazolidinone ring system is a fundamental structure which is present in a large variety of synthetic pharmaceuticals that has a wide range of potential biological effects. In this work, thioglycolic acid and 6-chloro-N-(substituted benzylidene)benzothiazol-2-amine were condensed in DMF solvent in the presence of ZnCl2 to obtain novel 3- (6-chlorobenzo[d]thiazol-2-yl)-2-(substituted aryl)thiazolidin-4-one derivatives. The structure of the synthesized compounds (3a-j) were confirmed using IR, 1H & 13C NMR and mass spectroscopy.

Two moles of benzaldehyde and one mole of acetone were condensed to afford dibenzalacetone in presence of sodium hydroxide. This aldol condensation was carried out in presence of magnetic copper ferrite, CuFe2O4, which was synthesized by hydrothermal method. Other magnetic ferrites (where M = Ni, Co, Zn and Mg) were also prepared. As-prepared metal ferrites were characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The copper ferrite was observed to be square shaped and particle size was 29.71 nm. The yield of product (dibenzalacetone) in presence of copper ferrite was found to be highest (90.6%). A comparative study was made with different metal ferrites as catalyst and found that the activity of metal ferrites followed the order: CuFe2O4 > ZnFe2O4 > NiFe2O4 > CoFe2O4 > MgFe2O4

Triazoles, a five-membered ring structure and three nitrogen atoms, are regarded as important building blocks for the synthesis of numerous organic compounds. Triazoles and their derivatives have received considerable attention over the past decade due to their chemotherapeutic value. It’s been thought to be a functional core that exhibits most varieties of biological activity mainly antibiotics, antimicrobials and antifungals. In present work, a series of novel substituted triazole phenylmethanones were synthesized using Claisen-Schmidt condensation reaction of 1-(5-methyl-1-(substituted phenyl)-1H- 1,2,3-triazol-4-yl)-ethan-1-one (3a-d) and some aromatic aldehydes. Final compounds (5a-f) were synthesized from compounds 4a-d, hydrazine hydrate and benzoic acid by sequential reactions having intermolecular conjugate addition and formation of hydrazone. All the intermediate and final compounds were characterized from the mass, elemental and 1H NMR spectral data.

In this research study, iron nanoparticles (FeNPs) were synthesized using Gymnema sylvestre (Asclepiadaceae) leaves extract. Iron(III) ions present in ammonium ferrous sulphate hexahydrate were reduced to FeNPs by phytoconstituents in Gymnema sylvestre leaves extract. The characteristics of biosynthesized FeNPs were studied by using UV-visible absorption spectroscopy (UV-vis), transmission electron microscopy (TEM), particle size analyzer (PSA) and Fourier transform infrared spectroscopy (FTIR). The typical absorption peak was found to lie within 650-700 nm due to the excitation of surface plasmon vibration in FeNPs. The spherical structures of FeNPs were found in the range of 8-40 nm with average particle size of 405.8 nm. The antibacterial study of the biosynthesized FeNPs was performed against Gram-positive (B. subtilis) bacteria and Gram-negative (E. coli) bacteria by the agar well dispersion technique. The zone of inhibition of antibacterial activity of FeNPs against B. subtilis and E. coli bacteria was found to be 27.5 and 29 mm, respectively.

In this work, design and synthesis of 5-(methylthio)-4-(H)-1,2,4-triazole-2-amine and its derivatives were carried out using N-cyano-carbonimidodithioic acid dimethyl ester and methane thiol hydrazine monohydrate to obtain an excellent yield of the desired core molecule. It was observed that free -NH2 group available at 2nd position, which itself acts as a pharmacophore useful to connect with alkyl/aryl substituted isocyanate and form urea moiety as a bridge between 5-(methylthio)-4-(H)-1,2,4-triazole and alkyl/aryl substituent which exhibited the antimicrobial and docking activities of the synthesized molecules. The QSAR, toxicokinetics, docking studies with selected antimicrobial PDBs are useful in silco study of derivatives. In this study, it is emphasised that the results obtained in vitro and in silico correspond with each other and provide a better understanding of how and where medications exert their effects at the molecular level. This is based on the fact that the results were found using the same drug.

Vision process involves the participation of two types of retinal photoreceptor cells: rod cells respond to dim light while cone cells respond to bright light and colours. The visual pigments in both types of photoreceptor cells contain the common chromophore, 11-cis-retinal, linked through a Schiff base linkage to the opsin protein, a member of G-protein coupled receptor (GPCR) family, composed of 7- transmembrane helices (a 7TM receptor). Rhodopsin is the visual pigment present in the rod cells while three distinct types of visual pigments known as photopsins (red cones, green cones and blue cones absorbing red, blue and green parts of the visible spectrum respectively) are present in the cone cells. Absorption of light by the visual pigment causes the photoexcitation followed by photoisomerization, 11-cis-retinal (Z) to all-trans-retinal (E) with a high quantum yield through a number of reactive intermediates characterized by low temperature and picosecond (ps) time resolved spectroscopies coupled with femtosecond spectroscopy. This photoisomerization leads to a change in the conformation of opsin GPCR and a signal transduction cascade by activating transducin, a heterotrimeric G-protein, to breakdown the cGMP to close the cGMP-gated cation channels resulting in hyperpolarization of the photoreceptor cell. This action potential creates a nerve signal that is transmitted to the brain to produce the sense of vision. The photoisomerized pigment undergoes rapidly hydrolysis to produce the opsin protein and all trans-retinal, which can be reconverted enzymatically to 11-cis-retinal for recharging opsin to generate the active visual pigment to maintain the vision cycle (Wald cycle). This brief review highlights the state of our understanding of the biology behind the art of vision in humans and other organisms.

A series of novel 2-aminothiazole derivatives were synthesized by microwave assisted method as a green chemistry approach and characterized by spectral techniques and elemental analysis. The antioxidant potential of the derivatives was determined by using molecular docking against two different oxidoreductase protein (PDB: 2CDU and 3NM8). Compounds 3a and 3d show the stronger binding affinity to the target protein. The synthesized drug was pharmacologically evaluated for the antioxidant activity using ascorbic acid as a reference drug, where compound 3a showed the highest inhibition.

The products were characterized by FT-IR, mass, 1H NMR and 13C NMR spectroscopy.","PeriodicalId":8544,"journal":{"name":"Asian Journal of Organic & Medicinal Chemistry","volume":"383 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75712433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
