In Silico Investigation of Traditional Chinese Medicine Compounds to Inhibit Human Histone Deacetylase 2 for Patients with Alzheimer’s Disease

الملخص EN

Human histone deacetylase 2 (HDAC2) has been identified as being associated with Alzheimer’s disease (AD), a neuropathic degenerative disease.

In this study, we screen the world’s largest Traditional Chinese Medicine (TCM) database for natural compounds that may be useful as lead compounds in the search for inhibitors of HDAC2 function.

The technique of molecular docking was employed to select the ten top TCM candidates.

We used three prediction models, multiple linear regression (MLR), support vector machine (SVM), and the Bayes network toolbox (BNT), to predict the bioactivity of the TCM candidates.

Molecular dynamics simulation provides the protein-ligand interactions of compounds.

The bioactivity predictions of pIC50 values suggest that the TCM candidatesm, (−)-Bontl ferulate, monomethylcurcumin, and ningposides C, have a greater effect on HDAC2 inhibition.

The structure variation caused by the hydrogen bonds and hydrophobic interactions between protein-ligand interactions indicates that these compounds have an inhibitory effect on the protein.
