Aryl butenoic acid derivatives as a new class of histone deacetylase inhibitors: synthesis in vitro evaluation and molecular docking studies
Authors:Esiyok, Peruze Ayhan; Seven, özlem; Eymur, Guluzar; Tatar, Gamze Bora; Erden, Didem Dayangaç; Yelekçi, Kemal; Yurter, Hayat; Demir, Ayhan S.
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.

Histone Deacetylase Inhibition Activity and Molecular Docking of (E )-Resveratrol: Its Therapeutic Potential in Spinal Muscular Atrophy
Authors:Dayangac-Erden, Didem; Bora, Gamze; Ayhan, Peruze; Kocaefe, Çetin; Dalkara, Sevim; Yelekçi, Kemal; Demir, Ayhan S.; Erdem-Yurter, Hayat
Publisher and Date:(Wiley, 2009)Spinal muscular atrophy is an autosomal recessive motor neuron disease that is caused by mutation of the survival motor neuron gene (SMN1) but all patients retain a nearly identical copy SMN2. The disease severity correlates inversely with increased SMN2 copy. Currently the most promising therapeutic strategy for spinal muscular atrophy is induction of SMN2 gene expression by histone deacetylase inhibitors. Polyphenols are known for protection against oxidative stress and degenerative diseases. ...

Homology modeling and normal mode analysis of human NR1-NR2A NMDA type receptors
N-Methyl-D-Aspartate (NMDA) receptors are ionotropic glutamate receptors located in the membrane of the nerve cells. The normal receptor activity has a vital importance in consciousness and normal brain functions. Neuronal death occurs as a result of overstimulation of NMDA-type glutamate receptors and leads to diseases such as stroke epilepsy Alzheimer's and Parkinson's. There are two recently available x-ray structures one from Xenopus laevis and the other one from Rattus norvegicus. First the ...

Molecular modifications on carboxylic acid derivatives as potent histone deacetylase inhibitors: Activity and docking studies
Authors:Bora-Tatar, Gamze; Dayangac-Erden, Didem; Demir, Ayhan S.; Dalkara, Sevim; Yelekçi, Kemal; Erdem-Yurter, Hayat
Publisher and Date:(Pergamon-Elsevier Science Ltd, 2009)In the light of known HDAC inhibitors 33 carboxylic acid derivatives were tested to understand the structural requirements for HDAC inhibition activity. Several modifications were applied to develop the structure-activity relationships of carboxylic acid HDAC inhibitors. HDAC inhibition activities were investigated in vitro by using HeLa nuclear extract in a fluorimetric assay. Molecular docking was also carried out for the human HDAC8 enzyme in order to predict inhibition activity and the 3D poses ...
