Dr. Deepa D Parab, Dr. Harmeet Kaur Kohli

Abstract :

The discovery of adamantane has inspired researchers to identify various drug molecules with a range of biological activities. Drugs containing adamantane ring demonstrate remarkable clinical efficacy. These drugs are recognised for their wide range of pharmacological activities like antiviral, antimicrobial, antidiabetic, and anticancer. In view of this, new 1-adamantyl derivatives were developed. The newly synthesized adamantane derivatives, N’-(4-hydroxy-3-methoxy benzylidene) adamantane-1-carbohydrazide (VAC) and N’-(3-ethoxy-4-hydroxy benzylidene) adamantane-1-carbohydrazide (EVAC) were synthesised and characterised employing diverse spectroscopic methods. They were evaluated for anti-bacterial activity against gram-negative bacteria, specifically Escherichia coli, against gram-positive bacteria specifically Staphylococcus aureus, Bacillus subtilis and for antifungal efficacy against Candida albicans. The broad spectrum antibiotic ampicillin was taken as the positive control. The results demonstrated that VAC and EVAC exhibited substantial bactericidal and fungicidal properties, with a Minimum Inhibitory Concentration in range of 3.91 to 15.62 μg/mL. The mode of interaction was studied by carrying molecular docking with Escherichia coli 6YD9, Staphylococcus aureus 1JIJ, Bacillus subtilis 1LNZ and Candida albicans 3QLW. The binding affinity score of best binding conformation was found in the range of -6.9 to -8.0 Kcal/mol.
