Alzheimer’s disease (AD) as a complicated and progressive neurodegenerative disorder is the most common form of dementia and memory loss. On account of the multifactorial etiology of AD, the multi-target-directed ligand (MTDL) approach is a promising method in searching new drug candidates for this disease. Here, in this paper more than 500 tacrine-coumarin hybrids have been designed and drug-l...
ABSTRACT: Quantitative structure-activity relationship (QSAR) study on the piperidone-grafted mono- and bis-spirooxindole-hexahydropyrrolizines as potent butyrylcholinestrase (BuChE) inhibitors were carried out using statistical methods, molecular dynamics and molecular docking simulation. QSAR methodologies, including classification and regression tree (CART), multiple linear regression (MLR),...
the aim of the study was to investigate the effect of tail-docking on the lh pulse frequency in femaletuj lambs. twelve female lambs were assigned into two equal groups. a rubber ring was applied to the baseof the tail for shedding off. blood samples were collected for 8 h in the 4th and 8th months of age todetermine pulsatile secretion of lh. starting from the age of 6 months, blood samples we...
In this study, we aimed to determine VEGFR-2, EGFR and PDGFR-β tyrosine kinase inhibitory activities of some pyrrolo[2,3-d]pyrimidine derivatives previously synthesized and showed potent cytotoxic and apoptotic effects against several cancer cell lines by our group and to evaluate the relationships between inhibitory activities and binding properties of the active compounds by molecular docking...
Glucokinase (GK) is involved in normal glucose homeostasis and therefore it is a valid target for drug design and discovery efforts. GK activators (GKAs) have excellent potential as treatments of hyperglycemia and diabetes. The combined recent interest in GKAs, together with docking limitations and shortages of docking validation methods prompted us to use our new 3D-QSAR analysis, namely, dock...
The inclusion of receptor flexibility in protein-ligand docking experiments has become a major research interest in drug discovery [1,2]. One of the possible methods applied is the use of multiple discrete protein conformations, so called ensemble docking [3,4]. With computational techniques like Molecular Dynamics (MD) a large number of different conformations can be generated, not all of whic...
In this work we use transition network analysis for the first time to investigate ligand migration in truncated hemoglobin (trHbN) and obtain kinetic information about the docking-site dynamics in the protein. A comparison with explicit water molecular dynamics simulations (100 ns in total) shows that the rate constants derived from the network analysis are realistic. The transition network ana...
Existing self-reconfigurable robots achieve connections and disconnections by a separate drive of the docking system. In this paper, we present a new docking system with which the connections and disconnections are driven by locomotion actuators, without the need for a separate drive, which reduces the weight and the complexity of the modules. This self-reconfigurable robot consists of two type...
background hymenodictyon excelsum is a medicinal plant traditionally used for tumor treatment as it contains phytochemicals of anthraquinone and coumarin class. objectives the aim of the present study was to unfold the therapeutic value of selected phytocompounds of hymenodictyon excelsum in prostate cancer. materials and methods eight phytochemicals were selected based on the literature search...
