Exploring the neuropharmacological properties of scopoletin-rich extract using and methods.

Objectives: This study investigates the neuropharmacologic properties of Scopoletin, a bioactive compound in (EA) extract, for managing cognitive impairment using , , and zebrafish embryo toxicity assays.

Methods: The study estimates Scopoletin concentration in EA extract using HPTLC, assesses antioxidant properties using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing ability of plasma (FRAP) assays, and uses bioinformatic tools for scopoletin targets. Zebrafish embryo toxicity (ZET) is used to assess its toxicological profile.

Aloe-emodin Quantification using HPTLC and RP-UHPLC in Extracts and Commercial Herbal Formulations: Evaluation of Antimicrobial and Antioxidant Effects.

Background: High-performance thin-layer chromatography (HPTLC) was developed and validated for the determination of aloe-emodin in accordance with ICH guidelines. In addition, a novel RP-UHPLC method was developed, and both methods were used to analyse the herbal extract and herbal formulation.

Methods: Separation was carried out on a silica gel 60 F HPTLC plate using the mobile phase Toluene: Methanol (9:1).

Synthesis, anticonvulsant and neurotoxicity screening of some novel 1,2,4-trisubstituted-1H-imidazole derivatives.

A series of 1,2,4-trisubstituted-1H- imidazole derivatives (4a-o) was synthesized by reacting 2,4-disubstituted-1H-imidazoles (3a-o) with chlorobenzene in the presence of triethylamine. Phenylglyoxal (2) was reacted with different aromatic aldehydes in the presence of ammonium acetate and glacial acetic acid to afford the disubstituted imidazoles (3a-o). The structures of the synthesized compounds were confirmed on the basis of their elemental analysis and spectral data results.
