Abstract:
Background: Fungal infections have posed a big challenge in the management of their
treatment. Due to the resistance and toxicity of existing drug molecules in the light of pandemic
infections, like COVID-19, there is an urgent need to find newer derivatives of active molecules,
which can be effective in fungal infections.
Objective: In the present study, we aimed to design pyrazole derivatives using molecular modeling
studies against target 1EA1 and synthesize 10 molecules of pyrazole derivatives using a multi-step
synthesis approach.
Methods: Designed pyrazole derivatives were synthesized by conventional organic methods. The
newly synthesized pyrazole molecules were characterized by using FT-IR, 1HNMR, 13CNMR, and
LC-MS techniques. Molecular docking studies were also performed. The antifungal activity of
newly synthesized compounds was assessed in vitro against Candida albicans and Aspergillus niger
using the well plate method.
Results: Two of the compounds, OK-7 and OK-8, have been found to show significant docking
interaction with target protein 1EA1. These two compounds have also been found to show significant
anti-fungal activity against Candida albicans and Aspergillus nigra when compared to the
standard fluconazole. The Minimum Inhibitory Concentration (MIC) value of these two compounds
has been found to be 50 μg/ml.
Conclusion: Pyrazole derivatives with -CH3, CH3O-, and -CN groups have been found to be active
against tested fungi and can be further explored for their potential as promising anti-fungal agents
for applications in the field of medicinal chemistry.
