Summary: Molecular docking studies were conducted to investigate the binding stability and feasibility of resorcinol-based acridinedione dyes (ADR1 and ADR2) with a globular protein, Human Serum Albumin (HSA). The results showed that ADR2 dye had a more stable and feasible binding with HSA compared to ADR1 dye. ADR1 dye predominantly bound to site I and III of HSA and acted as a hydrogen bonding acceptor, while ADR2 dye bound to all binding sites and acted as a hydrogen bonding donor. The importance of drug-governance on the binding affinity of dye-protein complex was also studied. Site I binding drugs decreased the binding affinity of ADR1 dye-HSA complex, while site II binding drugs predominantly decreased the affinity of ADR2 dye-HSA complex. The study highlights the utility of molecular docking in understanding the stability and binding of host-guest complexes. Rating: 8 out of 10.
