Eco-friendly Regioselective Synthesis, Biological Evaluation of Some New 5-acylfunctionalized 2-(1H-pyrazol-1-yl)thiazoles as Potential Antimicrobial and Anthelmintic Agents.
The present study describes an eco-friendly NBS-assisted regioselective synthesis of new 5-acylfunctionalized 5-acylfunctionalized 2-(1H-pyrazol-1-yl)thiazoles by condensation of 3,5-dimethyl-1H-pyrazole-1-carbothioamide with unsymmetrical 1,3-diketones under solvent-free conditions. The structural elucidation of the newly synthesized compounds was accomplished using various spectroscopic techniques viz. FTIR, NMR and mass spectrometry. All the newly synthesized compounds were examined for their in vitro antimicrobial potential against both pathogenic gram positive and gram negative bacterial and fungal species as well as anthelmintic activity against Pheretima posthuma earthworms. The results of antimicrobial activity revealed that all tested compounds 3 a-j showed excellent antimicrobial potential particularly against S. aureus. It was also observed that compounds 3 e and 3 i (MIC=62.5 μg/mL) showed greater potency against E. coli, whereas compounds 3 a and 3 h (MIC=50 μg/mL and 62.5 μg/mL) demonstrated better activity against P. aeruginosa and compound 3 i (MIC=62.5 μg/mL) exhibited superior activity against S. pyogenus when compared to standard drug Ampicillin (MIC=100μg/mL). Compound 3 e and 3 j revealed remarkable antifungal and anthelmintic activities. To find out binding interactions of target compounds with target proteins and pharmacokinetic parameters of the compounds, in silico investigations involving molecular docking studies and ADMET predictions were also performed.
期刊介绍:
ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
