Abstract
In this study, we worked on anticolon cancer effects and anti-Alzheimer's disease with molecular docking studies. Hamamelitannin, flavokawain A, and triacetyl resveratrol compounds showed good inhibitory activities on acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes. The inhibition effects of flavokawain A, hamamelitannin, and triacetyl resveratrol on AChE and BuChE enzymes were determined spectrophotometrically conforming to Ellman. IC50 values of these enzymes were ranging between 0.95 +/- 0.12 and 93.27 +/- 8.14 nM for AChE and 5.71 +/- 0.77 and 52.10 +/- 8.41 nM for BuChE. The inhibitory activities of some chemical compounds such as flavokawain A, hamamelitannin, and triacetyl resveratrol were assessed by performing the molecular docking study in the presence of AChE and BuChE. Also, the features of the ligand-enzyme complex had value of -7.722 kcal/mol for flavokawain A against AChE and -5.530 kcal/mol against BuChE. The molecular docking calculations indicated the probable interactions and their characteristics at an atomic level. Due to the outcomes gained from docking, the affinity of the chemical compounds to the enzymes was considerable. In vitro cell viabilities of flavokawain A, hamamelitannin, and triacetyl resveratrol with various concentrations on SW620, DLD-1, HT29, HCT8, and HCT116 were investigated by MTT assay with Doxorubicin as the control compound.
