New Quinazolin-4(3H)-One Derivatives Incorporating Isoxazole Moiety as Antioxidant Agents: Synthesis, Structural Characterization, and Theoretical DFT Mechanistic Study.

: This research centers on the development and spectroscopic characterization of new quinazolin-4(3H)-one-isoxazole derivatives (). The aim was to investigate the regioselectivity of the 1,3-dipolar cycloaddition involving arylnitriloxides and N-propargylquinazolin-4(3H)-one, and to assess the antioxidant properties of the synthesized compounds. The synthetic approach started with the alkylation of quinazolin-4(3H)-one using propargyl bromide, followed by a 1,3-dipolar cycloaddition reaction.

Phytochemical Profiling and Bioactive Potential of Moroccan Pulicaria Mauritanica Essential Oils: In-Silico and In Vitro Antibacterial and Antioxidant Assessment.

A study was conducted to analyze the essential oil of Pulicaria mauritanica (PMEO) and investigate its antibacterial and antioxidant properties using in-vitro and in-silico methods. The essential oil was extracted using the hydrodistillation technique, and its chemical composition was identified via GC/MS analysis. The chemical composition of the oil shows that the major components of PMEO are carvotanacetone (67.

Ruthenium(II) Complex-Based Tetradentate Schiff Bases: Synthesis, Spectroscopic, Antioxidant, and Antibacterial Investigations.

In this work, we describe the synthesis of novel Ruthenium (II) complex-based salen Schiff bases. The obtained Ruthenium (II) complexes are characterized using usual spectroscopic and spectrometric techniques, viz., IR, UV-Vis, NMR (H and C), powder X-ray diffraction, and HRMS.

Initial report on the multiple biological and pharmacological properties of hispolon: Exploring stochastic mechanisms.

The development of natural substances derived from nature poses a significant challenge as technologies for the extraction and characterization of active principles advance. Hispolon has received a lot of attention in recent years, ascribable to its wide range of biological activities. It is a phenolic molecule that was extracted from several mushroom species such as Phellinus igniarius, Phellinus linteus, Phellinus lonicerinus, Phellinus merrillii, and Inonotus hispidus.
