HDAC11 is a class IV histone deacylase with no crystal structure reported so far. The catalytic domain of shares low sequence identity other HDAC isoforms which makes the conventional homology modeling less reliable. AlphaFold neural network machine learning approach that can predict 3D proteins high accuracy even in absence similar structures. However fact models are predicted small molecules and ions/cofactors complicate their utilization for drug design. Previously we optimized an model by adding zinc ion minimization presence inhibitors. In current study implement comparative structure-based virtual screening utilizing previously to identify novel selective stepwise was successful identifying hit subsequently tested using vitro enzymatic assay. compound showed IC50 value 3.5 µM could selectively inhibit over subtypes at 10 concentration. addition carried out molecular dynamics simulations further confirm binding hypothesis obtained docking study. These results reinforce presented optimization applicability search inhibitors discovery.

Abstract Breakthrough achievements in protein structure prediction have occurred recently, mostly due to the advent of sophisticated machine learning methods and significant advancements algorithmic approaches. The most recent version AlphaFold model, known as “AlphaFold-latest,” which expands functionalities groundbreaking AlphaFold2, is subject this article. goal novel model predict three-dimensional structures various biomolecules, such ions, proteins, nucleic acids, small molecules, non-standard residues. We demonstrate notable gains precision, surpassing specialized tools across multiple domains, including protein–ligand interactions, protein–nucleic acid antibody–antigen predictions. In conclusion, framework has ability yield atomically-accurate structural predictions for a variety biomolecular hence facilitating drug discovery.

Evaluation of the binding affinities drugs to proteins is a crucial process for identifying drug pharmacological actions, but it requires three dimensional structures proteins. Herein, we propose novel computational methods predict therapeutic indications and side effects candidate compounds from human protein on proteome-wide scale. Large-scale docking simulations were performed 7,582 with 19,135 revealed by AlphaFold (including experimentally unresolved proteins), machine learning models affinity score (PBAS) profiles constructed. We demonstrated usefulness method predicting 559 diseases 285 toxicities. The enabled which related had not been determined successfully extract eliciting effects. proposed will be useful in various applications discovery.
