Docking is commonly applied to drug design efforts, especially high-throughput virtual screenings of small molecules, to identify new compounds that bind to a given target. Despite great advances and successful applications in recent years, a number of issues remain unsolved. Most of the challenges and problems faced when running docking experiments are independent of the specific software used...

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...

Computational screening of databases has become increasingly popular in the pharmaceutical research. Virtual screening uses computer based methods to discover new ligands on the basis of biological structures. Virtual screening is divided into structural based screening (docking) and screening using active compounds as templates (ligand based virtual screening). Ligand based screening technique...

Structure-based lead optimization approaches are increasingly playing a role in the drug-discovery process. Virtual screening by molecular docking has become a largely used approach to lead discovery in the pharmaceutical industry when a high-resolution structure of the biological target of interest is available. The performance of two docking programs (Arguslab and Surflex), for virtual databa...

For my course project I chose to explore docking software and its application to virtual screening. While there are many good reviews in the literature on docking software (e.g. Schneider, 2002), I wanted to supplement this material with some firsthand experience. I was able to gain access to three commercial docking programs, and while the software is both sophisticated and complex, was able t...

The binding of small molecule ligands to large protein targets is central to numerous biological processes. The accurate prediction of the binding modes between the ligand and protein, (the docking problem) is of fundamental importance in modern structure-based drug design. An overview of current docking techniques is presented with a description of applications including single docking experim...

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...

Four of the most well-known, commercially available docking programs, FlexX, GOLD, GLIDE, and ICM, have been examined for their ligand-docking and virtual-screening capabilities. The relative performance of the programs in reproducing the native ligand conformation from starting SMILES strings for 164 high-resolution protein-ligand complexes is presented and compared. Applying only the native s...

Screening of ligand molecules for target protein using computer-aided docking is a critical step in rational drug discovery. Based on this circumstances ,we attempted to develop a virtual screening application system, named VSDK virtual Screening by Docking, which can function under windows and linux both platform. The predicted model of Cytochrome P450 (CYP26A1) was used for virtual screening ...
