A series of few triazole linked hydroxamic acid derivatives were designed virtually considering the basic pharmacophore of suberoyl anilide hydroxamic acid (SAHA). The least energy conformers of each molecule was generated and docked with human histone deacetylase (HDAC8) with PDB id 1T69 using Autodock 4.0.1. Most of the molecules have shown significant binding interaction with the receptor. A...

The role of the aldose reductase in type 2 diabetes is widely described. Therefore, it is of interest to identify plant derived compounds to inhibit its activity. We studied the protein-ligand interaction of 267 compounds from different parts of seven plants (Allium sativum, Coriandrum sativum, Dacus carota, Murrayyakoneigii, Eucalyptus, Calendula officinalis and Lycopersicon esculentum) with a...

Few methods use molecular dynamics simulations in concert with atomically detailed force fields to perform protein–ligand docking calculations because they are considered too time demanding, despite their accuracy. In this paper we present a docking algorithm based on molecular dynamics which has a highly flexible computational granularity. We compare the accuracy and the time required with wel...

Molecular docking method was applied to research steric complementarity of 27 uracil derivatives modified into positions N, N, C, C by cyclic and acyclic substituents with the active site of thymidylate synthetase of mice Mus musculus. AutoDock 4.2 scoring function evaluated the thermodynamic characteristics of all compounds’ binding with the active site of the given enzyme. 17 uracil derivativ...

Biomedical applications have become increasingly complex, and they often require large-scale high-performance computing resources with a large number of processors and memory. The complexity of application deployment and the advances in cluster, grid and cloud computing require new modes of support for biomedical research. Scientific Software as a Service (sSaaS) enables scalable and transparen...

ATP-dependent Clp protease (ClpP) is a core unit of a major bacterial protease complex employing as a new attractive drug target for that isolates, which are resistant to antibiotics. Mycobacterium tuberculosis, a gram-positive bacterium, is one of the major causes of hospital acquired infections. ClpP in Mycobacterium tuberculosis is usually tightly regulated and strictly requires a member of ...

A series of new quinazoline derivatives has been recently reported as potent multi-acting histone deacetylase (HDAC), epidermal growth factor receptor (EGFR), and human epidermal growth factor receptor 2 (HER2) inhibitors. HER2 is one of the major targets for the treatment of breast cancer and other carcinomas. Three-dimensional structure-activity relationship (3D-QSAR) is a well-known techniqu...

Protein-ligand docking is a key computational method in the design of starting points for the drug discovery process. We are motivated by the desire to automate large-scale docking using our popular docking engine idock and thus have developed a publicly-accessible web platform called istar. Without tedious software installation, users can submit jobs using our website. Our istar website suppor...
