Flavonoid Profile, Biological Potentials, and In Silico Approaches of Methanol Extracts on AChE: Amaranthus retroflexus L.

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study investigated the flavonoid compounds and their biological activities in methanol extracts obtained from root, stem, leaf, and flower parts of Amaranthus retroflexus L. Flavonoids in the extracts were characterized for the first time by liquid chromatography–highresolution mass spectrometry (LC–HRMS), and a total of eight flavonoid ...

Antiprotozoal Activity of Highly Substituted Pyrazole and Pyrimidine Derivatives

ChemMedChem, EarlyView.
Based on previously identified antimalarial agents, a series of highly substituted pyrazole and pyrimidines derivatives has been synthesized and tested for antiplasmodial and antileishmanial activity. Selected derivatives show promising antiplasmodial effect with a predicted favorable pharmacokinetic profile.

Mutagenicity tests on propiverine hydrochloride.

The Journal of Toxicological Sciences, 1989
1. The reverse mutation test was carried out on propiverine hydrochloride (P-4) at dose range of 5-500 micrograms/plate use Salmonella typhimurium strains, TA100, TA98, TA1535 and TA1537, and Escherichia coli strain WP2uvrA. As compared with solvent-treated control, no significant increases were observed in the number of revertant colonies in all ...

Intracellular and Extracellular Efficacy of Homoisoflavone Derivatives Against Mycobacterium Tuberculosis: Progress Toward Novel Antitubercular Agents

ChemMedChem, EarlyView.
A series of 42 homoisoflavones were synthesized and evaluated against Mycobacterium tuberculosis (Mtb). Three derivatives showed potent inhibition of Mtb strains. Evaluation in infected macrophages revealed promising intracellular activity, where one derivative featuring a nitrofuranyl and piperidine group emerges as the most promising.
