UNLABELLED The Mur E enzyme of Mur pathway of Mycobacterium tuberculosis is an attractive drug target as it is unique to bacteria and is absent in mammalian cells. The virtual screening of large libraries of drug like molecules against a protein target is a common strategy used to identify novel inhibitors. However, the method has a large number of pitfalls, with large variations in accuracy ca...

We survey low cost high-throughput virtual screening (HTVS) computer programs for instructors who wish to demonstrate molecular docking in their courses. Since HTVS programs are a useful adjunct to the time consuming and expensive wet bench experiments necessary to discover new drug therapies, the topic of molecular docking is core to the instruction of biochemistry and molecular biology. The a...

The discovery of potent therapeutic compounds against dengue virus is urgently needed. The NS2B-NS3 protease (NS2B-NS3pro) of dengue fever virus carries out all enzymatic activities needed for polyprotein processing and is considered to be amenable to antiviral inhibition by analogy. Virtual screening of 300,000 compounds using Autodock 3 on the GVSS platform was conducted to identify novel inh...

G-protein-coupled receptors (GPCRs) play important physiological roles related to signal transduction and form a major group of drug targets. Prediction of GPCR-ligand complex structures has therefore important implications to drug discovery. With previously available servers, it was only possible to first predict GPCR structures by homology modeling and then perform ligand docking on the model...

UNLABELLED : Cinnamoyl CoA reductase (CCR) carries out the first committed step in monolignol biosynthesis and acts as a first regulatory point in lignin formation. CCR shows multiple substrate specificity towards various cinnamoyl CoA esters. Here, in Silico mutagenesis studies of active site residues of Ll-CCRH1 were carried out. Homology modeling based modeled 3D structure of Ll-CCRH1 was us...

A series of new N ′ -[(alkyl/aryl)sulfonyl]-1-(phenylsulfonyl)piperidine-4-carbohydrazide derivatives were synthesized. Starting from ethyl piperidine-4-carboxylate (a), first ethyl 1-(phenylsulfonyl)piperidine-4-carboxylate (1), second 1-(phenylsulfonyl)piperidine-4-carbohydrazide (2), and finally N ′ -[(alkyl/aryl)sulfonyl]-1-(phenylsulfonyl)piperidine4-carbohydrazides (4a–n) were synthesized...

The YAP oncogene is a known cancer target. Therefore, it is of interest to understand the molecular docking interaction of verteporfin (a derivative of benzo-porphyrin) with the WW domain of YAP (clinically used for photo-dynamic therapy in macular degeneration) as a potential WW domain-ligand modulator by inhibition. A homology protein SWISS MODEL of the human YAP protein was constructed to do...

New series of spiro indeno[1,2-b]pyrido[2,3-d]pyrimidine-5,3'-indolines as new urease inhibitors were synthesized by the catalytic procedure in high yield and short reaction time. In this method, biacidic carbon was prepared as a novel heterogeneous acid and was subsequently used as an efficient catalyst. The inhibitory activities of synthesized compounds were tested against Jack bean urease us...
