What is molecular Modelling & Drug Design?
Molecular modeling is an established computational toolbox to assist early drug discovery and development. It can be used to generate ideas on a compounds or macromolecules 3D conformation, protein–ligand interactions, and to make predictions on biological activities.
What is molecular Modelling Slideshare?
Molecular modelling encompasses all theoretical methods and computational techniques used to model or mimic the behaviour of molecules. This may include treating atoms as the smallest individual unit (the Molecular mechanics approach), or explicitly modeling electrons of each atom (the quantum chemistry approach).
What is molecular designing in drug discovery?
Designing new molecules for pharmaceuticals is primarily a manual, time-consuming process that’s prone to error. In this process, chemists select a target (“lead”) molecule with known potential to interact with a specific biological target, then tweak its chemical properties for higher potency and other factors.
What is the principle of molecular Modelling?
Molecular models typically describe atoms (nucleus and electrons collectively) as point charges with an associated mass. The interactions between neighbouring atoms are described by spring-like interactions (representing chemical bonds) and Van der Waals forces.
What do you mean by molecular Modelling?
Molecular modeling is the science of representing molecular structures numerically and simulating their behavior with the equations of quantum and classical physics.
What is molecular docking PPT?
Docking is a method which predicts the preferred orientation of one ligand when bound in an active site to form a stable complex. Docking of small molecule ligand (brown) with a protein receptor (green) to produce a complex.
What is drug design Slideshare?
INTRODUCTION TO RATIONAL DRUG DESIGN Rational drug design is a process in which finding of new medication is based on knowledge of biological target. It involves design of small molecules that are complementary in shape and charge to bimolecular target.
What is meant by molecular Modelling?
Molecular modelling encompasses all methods, theoretical and computational, used to model or mimic the behaviour of molecules. The common feature of molecular modelling methods is the atomistic level description of the molecular systems.

What does molecular modelling do for a scientist?
• Molecular modelling allow scientists to use computersto visualize molecules means representing molecularstructures numerically and simulating their behaviorwith the equations of quantum and classical physics , todiscover new lead compounds for drugs or to refineexisting drugs in silico.•
How is rational drug design used in drug discovery?
Rational drug design Application of biocomputing in drug design/discovery • Optimize the pharmacological profile of existing drugs by predicting structure and properties of new compounds • Use the available structural information on possible protein targets and their biochemical role in the cell to develop novel therapeutic concepts 13.
What is the molecular basis of drug specificity?
10. Molecular basis of Drug specificity Molecular specificity involves • Binding of drug to target with suitable affinity (High affinity = Low doses, fewer side effects) •Affect activity of the target 11. Proteins as Targets of drugs Proteins are the cellular targets of many drugs.
