Abstract:

Background: β-Cyclodextrin, a cyclic oligosaccharides having 7 macrocyclic rings of glucose subunits usually linked together by α-1,4 glycosidic bond, bears characteristic chemical structure, with an exterior portion as hydrophilic to impart water solubility and interior cavity as hydrophobic, for hosting the hydrophobic molecules.

Objective: In the present work binding affinities and interactions between various anti-cancerous drugs and β- cyclodextrin using molecular docking simulations was examined for the bioavailability enhancement of cytotoxic drugs through improved solubility for the treatment of breast cancer.

Methods: Molegro Virtual Docker, an integrated software was used for the prediction and estimation of interaction between β-cyclodextrin and anti cancerous drugs.

Results: Out of tested anti cancerous drug, Olaparib having pyridopyridazione scaffold possess highest MolDock (-130.045) and Re-ranks score (-100.717), ensuring strong binding affinity. However, 5-Fluoro Uracil exhibited the lowest MolDock score (-61.0045), indicating weak or no binding affinity, while few drugs showed no H-bond interaction with the β-cyclodextrin.

Conclusion: The binding conformations of anti cancerous drugs obtained from the present study can be selected for the development of improved formulation having superior solubility which will lead to attain better pharmacological profile with negligible toxicity.

Keywords: Breast cancer, anti-cancerous drugs, β-cyclodextrin, molecular docking, docking scores, novel drug delivery systems.
