Synopsis

This unit provides an introduction to the techniques and applications of molecular modelling with particular emphasis on methods used in drug design. The unit contains two streams:

  1. modelling methods; which introduces quantum mechanics, molecular mechanics, energy optimisation and molecular simulation and
  2. modelling applications; which covers quantitative structure-activity relationships (QSAR), pharmacophores, structure-based drug design and homology modelling.


This will involve:
  • Modelling methods in computational chemistry
  • Applications of molecular modelling

Objectives

At the end of this unit students will have:

  • A broad understanding of computational chemistry and its application to drug bimolecular problems.
  • An understanding of common molecular modelling terminology. - An appreciation of the factors involved in performing quantum mechanical (QM) calculations and the information that these calculations can provide.
  • An appreciation of molecular mechanisms energy calculations and the information that these calculations can provide.
  • An understanding of the components making up molecular mechanic force fields including bond stretching, angle bending and dihedral angle terms and nonbonded interactions (van der Waals and electrostatic).
  • An understanding of molecular potential energy surfaces and the concepts of global and local minima. - An appreciation of energy optimisation methods including steepest descents and conjugate gradient methods.
  • An appreciation of approaches to finding global energy minima.
  • An understanding of the Boltzmann distribution and the relationship between temperature and the population of energetic states.
  • An appreciation of molecular simulation methods.
  • An understanding of drug physicochemical properties including electronic, steric and hydrophobic characteristics.
  • An understanding of the statistical methods used to develop QSAR equations
  • An appreciation of the application of QSAR in drug discovery.
  • An appreciation of impact of drug physicochemical parameters on biopharmaceutical properties.
  • Un understanding of the pharmacophore concept and its use in drug discovery.
  • An appreciation of structure and ligand-based drug design.
  • An appreciation of homology modelling methods.
  • The ability to use a specific molecular modelling package to study molecular conformation and analyse drug-receptor interactions.
  • Describe the molecular interactions which govern molecular structure including bonded, non-bonded and electrostatic interactions.

After completing this unit the student will have the following practical skills:
  • Perform simple molecular modeling studies using the molecular modeling package Sybyl.
  • Describe the processes involved in molecular mechanics energy calculations.
  • Explain the processes involved in running quantum mechanics calculations.
  • Interpret and critique a QSAR equation.
  • Generate statistically acceptable QSAR equations from physicochemical parameters and biological activity data.
  • Derive simple pharmacophore models.
  • Describe protein-ligand interactions and how an understanding of these can be applied to drug design.
  • Investigate a research topic using literature sources and write a simple report.
