In this study, a series of phenyl, furyl and 1H-1,2,4-triazole substituted benzyl and alkyl ethers were synthesized, characterized by all spectral analysis, and evaluated for their antibacterial and antifungal activities against Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli, Candida albicans and Candida krusei. From phenyl substituted series, compound 1-(2-(3,4-dichlorobenzyloxy)-2phenylethyl)-1H-1,2,4-triazole (7 i) exhibited the most potent antibacterial activity with lowest MIC value of 6.25 μg/mL against MRSA and from furyl substituted series, most of the compounds exhibited the most potent antifungal activity with lowest MIC value of 6.25 μg/mL against Candida Krusei. Furthermore, the absorption, distribution, metabolism, and excretion (ADME) and drug-likeness characteristic of the compounds were calculated, and it was observed that all compounds met majority the criteria of five different drug filters. Finally, docking simulations revealed that some compounds showed high affinity to an CYP51 antifungal target structure (PDB: 3L4D).
In the molecule of the title compound, C15H13Cl2N3O2, the triazole ring is oriented at dihedral angles of 14.8 (2) and 81.5 (1)° to the furan and dichlorobenzene rings, respectively. The dihedral angle between the dichlorobenzene and furan rings is 86.3 (2)°. An intramolecular C—H⋯O hydrogen bond results in the formation of a planar [maximum deviation 0.012 (2) Å] five-membered ring, which is oriented at a dihedral angle of 0.90 (7)° with respect to the dichlorobenzene ring. There is an intermolecular C—H⋯π contact between the methylene group and the dichlorobenzene ring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
