MOLECULAR DOCKING OF ANTITRYPANOSOMAL INHIBITORS FROM EUCALYPTUS TERETICORNIS FOR SLEEPING SICKNESS
Journal Title: Asian Journal of Pharamceutical and Clinical Research - Year 2019, Vol 12, Issue 9
Abstract
Objectives: This study aims to investigate the antitrypanosomal inhibitors of Eucalyptus tereticornis for sleeping sickness through molecular docking and studies on Absorption distribution metabolism excursion and toxicology (ADMET). Methods: In silico molecular docking in ArgusLab software and ADMET analysis in AdmetSAR software was performed for the antitrypanosomal inhibitors of E. tereticornis for sleeping sickness. Results: Interactions were studied for the ten proteins responsible for sleeping sickness with the 50 antitrypanosomal inhibitors of E. tereticornis. Docking was performed to see the interaction and the best binding energy of compounds with the proteins involved in sleeping sickness. The docking scores were highest for betulonic acid with −15.66 kcal/mol followed by euglobal with −12.24 kcal/mol, B-pinene with −10.313 kcal/mol, A-pinene with −10.3418 kcal/mol, and the least docking score for P-cymene with −10.6045 kcal/mol. Docking results showed that only betulonic acid and euglobal showed that hydrogen bond interaction was as b-pinene, a-pinene, and p-cymene yielded no hydrogen bond interactions so we will be taking the former docking results for further studies. The best docking result was shown by betulonic acid with trypanothione reductase giving binding energy of −15.66 kcal/mol with hydrogen bond interaction of 2.9, so this result was taken for further analysis. Conclusion: The results of the compound extracted from E. tereticornis will become physiological relevant only when (i) the pure compounds of this plant is available in large quantities; (ii) the Eucalyptus is biochemically stabilized to avoid degradation and enhance absorption in the gastrointestinal tract; and (iii) special delivery methods for this drug to reach the areas of treatment. In this work, the efficacy of E. tereticornis to act against trypanosomal protein was initiated and thus further research in this process would help us to take full advantage of the remedial effects of the compounds extracted from this plant.
