objective(s): alzheimer’s disease (ad) as progressive cognitive decline and the most common form of dementia is due to degeneration of the cholinergic neurons in the brain. therefore, administration of the acetylcholinesterase (ache) inhibitors such as donepezil is the first choice for treatment of the ad. in the present study, we focused on the synthesis and anti-cholinesterase evaluation of n...
interference with microtubule polymerization results in cell cycle arrest leading to cell death. colchicine is a well-known microtubule polymerization inhibitor which does so by binding to a specific site on tubulin. a set of 3',4'-bis (substituted phenyl)-4'h-spiro[indene-2,5'-isoxazol]-1(3h)-one derivatives with known antiproliferative activities were evaluated for their t...
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...
Computational protein-ligand docking is of great importance in drug discovery and design. Conformational changes greatly affect the results of protein-ligand docking, especially when water molecules take part in mediating protein ligand interactions or when large conformational changes are observed in the receptor backbone interface. We have developed an improved protocol, SWRosettaLigand, base...
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...
Cholinesterase Inhibition Activity and Docking Simulation Study of Coumarin Mannich Base Derivatives
Inhibition of acetylcholinesterase and butyrylcholinesterase (AChE and BuChE) as two major forms of cholinesterases (ChEs) is considered as the common approach for the treatment of Alzheimer's disease (AD). The present study was done to explore the anticholinesterase inhibition property of coumarin Mannich base derivatives. A series of cumarin Manich bases were synthesized (4a-h) through one-po...
Gap junction (GJ) channels mediate direct intercellular communication and are composed of two docked hemichannels (connexin oligomers). It is well documented that the docking and formation of GJs are possible only between compatible hemichannels (or connexins). The mechanisms of heterotypic docking compatibility are not fully clear. We aligned the protein sequences of docking-compatible and -in...
Tail docking of piglets is a routine procedure on farms to control tail-biting behaviour; however, docking can cause an acute stress response. The objectives of this research were to determine the stress responses to tail docking in piglets and to compare two methods of tail docking; cautery iron (CAUT) and the more commonly used blunt trauma cutters (BT). At approximately 6 days of age, piglet...
Interaction profile method is a useful method for processing rigid-body docking. After the docking process, the resulting set of docking poses could be classified by calculating similarities among them using these interaction profiles to search for near-native poses. However, there are some cases where the near-native poses are not included in this set of docking poses even when the bound-state...
Several small-molecule CDK inhibitors have been identified, but none have been approved for clinical use in the past few years. A new series of 4-[(3-hydroxybenzylamino)-methylene]-4H-isoquinoline-1,3-diones were reported as highly potent and selective CDK4 inhibitors. In order to find more potent CDK4 inhibitors, the interactions between these novel isoquinoline-1,3-diones and cyclin-dependent...
