Aryl butenoic acid derivatives as a new class of histone deacetylase inhibitors: synthesis in vitro evaluation and molecular docking studies Authors:
Publisher and Date:(Scientific Technical Research Council Turkey-Tubitak, 2014)New aryl butenoic acid derivatives have been synthesized by combining hydroxy- or methoxy-substituted phenyl rings as the capping group with a double bond in the short linker as well as metal binding groups enoic ester and salts bearing either methyl or morpholine. These compounds have been shown to possess promising histone deacetylase inhibition activities via in vitro fluorometric assay and molecular docking studies.
Publisher and Date:(Scientific Technical Research Council Turkey-Tubitak, 2003)In this study a double antibody enzyme immunoassay for the direct determination of testosterone in plasma was developed. Testosterone 3-O-CMO was conjugated with horseradish peroxidase by the mixed anhydride method and the conjugate purified by column chromatography (sephadex G-25). Testosterone antibody was obtained by immunization of rabbits against Testosterone-3-O-CMO-BSA. Cross reactions of the antiserum against some steroids were found to be <0.01%. The detection limit of the assay was 2.5 ...
Exploring distinct binding site regions of beta(2)-adrenergic receptor via coarse-grained molecular dynamics simulations Authors:
Publisher and Date:(Scientific Technical Research Council Turkey-Tubitak, 2013)beta(2)-Adrenergic receptor (beta(2)AR) is a G protein-coupled receptor that is highly flexible and able to recognize a wide range of ligands through its conformational variations. Active and inactive conformations revealed by recent crystallographic experiments do not provide a complete dynamic picture of the receptor especially in the binding site. In this study molecular dynamics (MD) simulation through a residue-based coarse-grained model is used as an alternative and efficient method to explore ...
Publisher and Date:(Scientific Technical Research Council Turkey-Tubitak, 2011)Histone lysine-specific demethylase (LSD1) is involved in a wide range of epigenetic processes and plays important roles in gene silencing DNA transcription DNA replication DNA repair and heterochromatin formation. Its active site shows a resemblance to those of 2 homologous enzymes monamine oxidase A and B (MAO-A and MAO-B.) In the present work starting from suitable scaffolds and generating thousands of structures from them 10 potential inhibitors were obtained with structural and physicochemical ...
Power of inhibition activity screening and 3D molecular modeling approaches in HDAC 8 inhibitor design Authors:
Publisher and Date:(Scientific Technical Research Council Turkey-Tubitak, 2011)In-vitro inhibition activity screening and in-silico 3D molecular modeling approaches are important tools for design and development of specific histone deacetylase (HDAC) inhibitors. The objective of this study was to investigate the consistency between these 2 approaches. The HDAC 8 inhibition activities of 8 randomly selected different carboxylic acid derivatives were screened and in-vitro experimental results were compared with in-silico molecular modeling calculations. This study demonstrated ...
