In this study, new benzimidazole-triazole derivatives were synthesized
in two steps. First, 4-benzaldehyde derivatives are synthesized by
reacting 1,2,4-triazole ring and 4-fluorobenzaldehyde. In the last step,
the benzimidazole ring was obtained with o-phenylenediamine derivatives
under microwave radiation. The structures of synthesized compounds were
confirmed by 1 H-NMR, 13 C-NMR, infrared spectroscopy, mass
spectroscopy, and elemental analysis. Antimicrobial activity of
synthesized compounds is associated with six different types of bacteria
(Escherichia coli ATCC 35218, E.coli ATCC 25922, Klebsiella pneumoniae
NCTC 9633, Pseudomonas aeruginosa ATCC 27853, Salmonella typhimurium
ATCC 13311, Staphylococcus aureus ATCC 25923), and four different
Candida (C. albicans ATCC 24433, C. glabrata ATCC 90030, C. krusei ATCC
6258, C. parapsilosis ATCC 22019). Synthesized compounds showed weak
antibacterial activity. However, 3a, 3b, and 3c compounds against C.
albicans of the Candida species were found to show promising activity.
Given the effect of substituents on antifungal activity, it is seen that
the compounds 3a, 3b, and 3c carry chlorine, methyl, and fluoro
substituents on the benzimidazole ring attract attention with higher
activities. Molecular docking studies of 3a, 3b, and 3c were performed
Schrödinger Glide XP against Candidas' sterol 14-alpha demethylase
(CYP51), and estimated ADME calculations were analyzed.
