CuO nanoparticles for green synthesis of significant anti-Helicobacter pylori compounds with in silico studies

Helicobacter pylori (H. pylori) is a universal health intimidation as mentioned by the World Health Organization. The primary causal agent linked to a number of illnesses, including inflammation and the development of stomach ulcers, is Helicobacter pylori. Since, H. pylori develops antibiotic resistance quickly, current H. pylori treatment approaches are becoming less effective. Our research aims to highlight novel formulation antibiotics using CuO-NPs as catalysts and studied their activity as anti-helicobacter pylori supported by computational studies (POM analysis and molecular docking) software. They were designed for anti-Helicobacter Pylori action. All compounds revealed a bactericidal effect better than the reference McFarland standards.

A Study on Synthesis of Chalcone Derived -5- Membered Isoxazoline and Isoxazole Scaffolds

Chalcone-derived Isoxazole scaffolds remain the central focus because of their greater biological, clinical, and pharmacological properties. The present study reviews the synthesis of various chalcone derived - 5- Membered Isoxazoline and Isoxazole Scaffolds with the available literature until 2021. Keywords: Chalcones, Isoxazoles, Isoxazolines, Biological and Pharmacological properties.

Effect of a Substituent in the Fourth Position on the Optical Properties of 2-Oxonicotinonitriles

Based on six representatives of 2-oxonicotinonitriles, the effect of the nature of the substituent in the fourth position of the pyridine system on the photophysical characteristics was studied. The role of the donor/acceptor nature of the substituent and the solvent nature in the absorbing and fluorescent properties of the compounds was shown.

CDATA[Recent Advances in the Development of 1,2,3-Triazole-containing Derivatives as Potential Antifungal Agents and Inhibitors of Lanoster ol 14α-Demethylase

1,2,3-Triazole, a five-membered heterocyclic nucleus, is widely recognized as a key chromophore of great value in medicinal chemistry for delivering compounds possessing innumerable biological activities, including antimicrobial, antitubercular, antidiabetic, antiviral, antitumor, antioxidants, and anti-inflammatory activities. Mainly, in the past years, diverse conjugates carrying this biologically valuable core have been reported due to their attractive fungicidal potential and potent effects on various infective targets. Hence, hybridization of 1,2,3-triazole with other antimicrobial pharmacophores appears to be a judicious strategy to develop new effective anti-fungal candidates to combat the emergence of drug-sensitive and drug-resistant infectious diseases. Thus, the current review highlights the recent advances of this promising category of 1,2,3-triazole-containing hybrids incorporating diverse varieties of bioactive heterocycles such as conozole, coumarin, imidazole, benzimidazole, pyrazole, indole, oxindole, chromene, pyrane, quinazoline, chalcone, isoflavone, carbohydrates, and amides. It underlies their inhibition behavior against a wide array of infectious fungal species during 2015-2020.
