ABSTRACT
Curcumin analogues are widely used in numerous biological disciplines. They are widely employed in the pharmaceutical sector and offer good pharmacology application prospects in the present era. In the current study, two curcumin analogues—1,7-diphenylhepta-1,6-diene-3,5-dione (DPHDD) and 1,7-bis(3,4-dimethoxyphenyl)hepta-1,6-diene-3,5-dione (BDMPHDD)—were tested in vitro against the bacterial strain S. aureus. The testing demonstrated that the ligands may have antibacterial potential. The rule of five was used to pre-filter the compounds' drug-like characteristics prior to computer analysis. Then, to determine the mechanism by which the compounds limit the growth of S. aureus, molecular docking research was carried out using the AutoDock 4.2 tool. Six distinct target proteins from S. aureus were chosen for this purpose (PDB ID: 1T2P, 3U2D, 2W9S, 1N67, 2ZCO, and 4H8E). The target protein Dihydrofolate reductase enzyme (PDB ID: 2W9S) and Staphylococcus aureus sortase-A (PDB ID: 1T2P) demonstrated a good binding affinity for the two analogues, (BDMPHDD) & (DPHDD) respectively.Due to the inactivation of these enzymes, the substances 1,7-diphenylhepta-1,6-diene-3,5-dione (DPHDD) and 1,7-bis(3,4-dimethoxyphenyl)hepta-1,6-diene-3,5-dione (BDMPHDD) exhibit significant growth-inhibitory potential against S. aureus.
