Carboxylic acid derivatives display potential selectivity for human histone deacetylase 6: Structure-based virtual screening molecular docking and dynamics simulation studies
Authors:
Publisher and Date:(Elsevier Science, 2018)Human histone deacetylase 6 (HDAC6) has been shown to play a major role in oncogenic cell transformation via deacetylation of alpha-tubulin making it a viable target of anticancer drug design and development. The crystal structure of HDAC6 catalytic domain 2 has been recently made available providing avenues for structure-based drug design campaign. Here in our continuous effort to identify potentially selective HDAC6 inhibitors structure-based virtual screening of similar to 72 461 compounds was ...

Crystallographic structure versus homology model: a case study of molecular dynamics simulation of human and zebrafish histone deacetylase 10
Authors:
Publisher and Date:(Taylor & Francis, 2020)Histone deacetylase (HDAC) 10 has been implicated in the pathology of various cancers and neurodegenerative disorders, making the discovery of novel inhibitors of the isoform an important endeavor. However, the unavailability of crystallographic structure of human HDAC10 (hHDAC10) hinders structure-based drug design effort. Previously, we reported the homology modeled structure of human HDAC10 built using the crystallographic structure of Danio rerio (zebrafish) HDAC10 (zHDAC10) (Protein Data Bank ...

The design of potent HIV-1 integrase inhibitors by a combined approach of structure-based virtual screening and molecular dynamics simulation
Authors:
Publisher and Date:(Taylor & Francis Ltd, 2018)Bu araştırmanın amacı, AIDS olarak bilinen insan bağışıklık sistemine etki eden, duraksamayan ve depresif bir hastalığa neden olan HIV-1'in tedavisi için potansiyel inhibitörleri elde etmektir. HIV-1 integraz inhibitörleri, HIV-1 enfeksiyonunun tedavisinde çok önemlidir. İntegraz enziminin (IN) inhibe edilmesi HIV-1 virüsünün çoğalma işleminin sonlandırılmasına neden olur. Böylece yaşam döngüsüne son verir. Bu inhibitörleri elde etmek için bilgisayar destekli in silico yaklaşım kullanılmıştır. ...

Examining the stability of binding modes of the co-crystallized inhibitors of human HDAC8 by molecular dynamics simulation
Authors:
Publisher and Date:(Taylor & Francis Inc, 2019)Histone deacetylase (HDAC) 8 has been implicated as a potential therapeutic target in a variety of cancers neurodegenerative disorders metabolic dysregulation and autoimmune and inflammatory diseases. Several nonselective HDAC inhibitors have been co-crystallized with HDAC8. Molecular dynamics (MD) studies may yield valuable information on the structural stabilities of the complexes over time as determined by various pharmacophore features of the co-crystallized inhibitors. Here using 11 unmodified ...

Homology modeling of human histone deacetylase 10 and design of potential selective inhibitors
Authors:
Publisher and Date:(Taylor & Francis, 2019)Histone deacetylases (HDACs) are implicated in the pathology of various cancers, and their pharmacological blockade has proven to be promising in reversing the malignant phenotypes. However, lack of crystal structures of some of the human HDAC isoforms (e.g., HDAC10) hinders the design of the isoform-selective inhibitor. Here, the recently solved X-ray crystal structure of Danio rerio (zebrafish) HDAC10 (Protein Data Bank (PDB) ID; 5TD7, released on 24 May 2017) was retrieved from the PDB and used ...

Identification of potential isoform-selective histone deacetylase inhibitors for cancer therapy: a combined approach of structure-based virtual screening ADMET prediction and molecular dynamics simulation assay
Authors:
Publisher and Date:(Taylor & Francis Inc, 2018)Histone deacetylases (HDACs) have gained increased attention as targets for anticancer drug design and development. HDAC inhibitors have proven to be effective for reversing the malignant phenotype in HDAC-dependent cancer cases. However lack of selectivity of the many HDAC inhibitors in clinical use and trials contributes to toxicities to healthy cells. It is believed that the continued identification of isoform-selective inhibitors will eliminate these undesirable adverse effects - a task that ...

Synthesis, molecular modeling, in vivo study and anticancer activity against prostate cancer of (+) (S)-naproxen derivatives
Authors:
Publisher and Date:(Elsevier Masson s.r.l., 2020)In this study, (S)-naproxen thiosemicarbazides (3a-d), 1,2,4-triazoles (4a-c), triazole-thioether hybride compounds (5a-p) were synthesized and their structures (3a, 3d, 4a and 5a-p) were confirmed by FT-IR, 1H NMR,13C NMR, HR-Mass spectra and elemental analysis. These compounds are designed to inhibit methionine amino peptidase-2 (MetAP2) enzyme in prostate cancer. These compounds (3d, 5a-p) evaluated against androgen-independent prostate adenocarcinoma (PC-3, DU-145) and androgen-dependent ...
