چکیده

Histone-modifying proteins have been identified as promising targets to treat several diseases including cancer and parasitic ailments. In silico methods incorporated within a variety of drug discovery programs facilitate the identification development novel lead compounds. this study, we explore binding modes series benzhydroxamates derivatives developed histone deacetylase inhibitors Schistosoma mansoni (smHDAC) using molecular docking free energy (BFE) calculations. The protocol was able correctly reproduce experimentally established resolved smHDAC8–inhibitor complexes. However, has reported in former studies, obtained scores weakly correlate with determined activity studied inhibitors. Thus, poses were refined rescored Amber software. From computed protein–inhibitor BFE, different quantitative structure–activity relationship (QSAR) models could be validated cross-validation techniques. Some generated QSAR good correlation explain up ~73% variance training set molecules. best performing subsequently tested on an external test newly designed synthesized analogs. vitro testing showed between predicted observed IC50 values. can considered interesting tools for smHDAC8

Analysis of the interactome of Schistosoma mansoni histone deacetylase 8

BACKGROUND Histone deacetylase 8 from Schistosoma mansoni (SmHDAC8) is essential to parasite growth and development within the mammalian host and is under investigation as a target for the development of selective inhibitors as novel schistosomicidal drugs. Although some protein substrates and protein partners of human HDAC8 have been characterized, notably indicating a role in the function of ...

A lazy learning-based QSAR classification study for screening potential histone deacetylase 8 (HDAC8) inhibitors.

Histone deacetylases 8 (HDAC8) is an enzyme repressing the transcription of various genes including tumour suppressor gene and has already become a target of human cancer treatment. In an effort to facilitate the discovery of HDAC8 inhibitors, two quantitative structure-activity relationship (QSAR) classification models were developed using K nearest neighbours (KNN) and neighbourhood classifie...

A Novel Class of Schistosoma mansoni Histone Deacetylase 8 (HDAC8) Inhibitors Identified by Structure-Based Virtual Screening and In Vitro Testing.

A promising means in the search of new small molecules for the treatment of schistosomiasis (amongst other parasitic ailments) is by targeting the parasitic epigenome. In the present study, a docking based virtual screening procedure using the crystal structure of histone deacetylase 8 from Schistosoma mansoni (smHDAC8) was designed. From the developed screening protocol, we were able to identi...
