This study focused on synthesis and molecular docking analysis of 4,4'-dimethoxychalcone and 3,4,4'-trimethoxychalcone. The aims of this study were to synthesize and evaluate the activity of 4,4'-dimethoxychalcone and 3,4,4'-trimethoxychalcone as anticancer candidate through molecular docking. The synthesis was done through Claisen-Schmidt condensation between 4-methoxyacetophenone and benzaldehyde derivatives (4-methoxybenzaldehyde and 3,4-dimethoxybenzaldehyde) using KOH 30% as catalyst in ethanol solvent. In this synthesis, stirring method was used at room temperature for 24 hours to produce 4,4'-dimethoxychalcone and 3,4,4'-trimethoxychalcone. The anticancer activity test of the synthesized chalcones was done by docking the chalcones with estrogen receptor alpha and beta (ER alpha and ER beta proteins) PDB ID: 1X7R and 1QKM.
The synthesis results showed the characteristics of 4,4'-dimethoxychalcone and 3,4,4'-trimethoxychalcone were pale yellow solid with yield of 65.7% and 47.0%. The molecular docking results showed that 4,4'-dimethoxychalcone had lower binding energy toward ER alpha protein (-7.88 kcal/mol) and 3,4,4'-trimethoxychalcone had lower binding energy toward ER beta protein (-8.19 kcal/mol). Similar to genistein as native ligand and tamoxifen, both chalcones formed interactions with Glu353, His524, and Leu525 residue of ER alpha protein (PDB ID: 1X7R) and Glu305, Leu298, His475, Leu476 and Met340 residue of ER beta protein (PDB ID: 1QKM).
