Kenneth MerzKeynote Presentation

How Accurate are Docking Calculations Anyway?
Kenneth Merz, Professor, University of Florida, United States of America

Docking calculations are a mainstay of structure-based drug design and this talk addresses the central question regarding how potential function errors affect the (un)successful outcome of a docking effort. We analyze and estimate the magnitude of potential function error and demonstrate how to use this knowledge to improve the outcome of a docking exercise.

09:30

Improvements in Docking Scoring Functions: The Physics-Based Perspective
Xavier Barril, Research Professor, University of Barcelona, Spain

This talk will discuss the application of first-principle simulations to improve docking performance, focussing on three different aspects: the internal energy of ligands, the kinetics of binding and the protein-ligand binding free energy.

10:00

Separating Good Models from Bad: The Role of Experimental Structural Information in Validation and Calibration
John Liebeschuetz, Head of Research, Cambridge Crystallographic Data Centre, United Kingdom

The talk explores the role of experimental small molecule structural information for the validation of structural models and the calibration of computational methods, in the fields of protein crystallography, drug design and crystal engineering.

Protein-Ligand Interactions

11:15

Protein-Ligand Binding Free Energy and Kinetics
Andrea Cavalli, Associate Professor, University of Cambridge, United Kingdom

Protein-ligand binding free energy is fundamental to evaluate the affinity of a small molecule for its biological counterpart. Binding kinetics has recently emerged as a key factor influencing in vivo drug efficacy. By means of molecular dynamics simulations and enhanced sampling methods, we can try to estimate protein-ligand binding free energy and kinetics.

11:45

Rigorous Free Energy Calculations in Drug Discovery: Applications and Pitfalls
Jonathan Essex, Head, University of Southampton, United Kingdom

In this presentation, the use of rigorous free energy calculations in the drug discovery context will be described. Particular emphasis will be placed on addressing the applicability of these methods to lead identification and optimisation, and the consequences of the approximations made in affecting their accuracy.

Holger GohlkeKeynote Presentation

Rigorous and Approximate Computation of Entropy Changes Upon Complex Formation
Holger Gohlke, Professor, Heinrich-Heine-University Düsseldorf, Germany

Changes in the degrees of freedom of binding partners and solvent lead to entropic contributions to affinity. We show that rigorous Delta S calculations for protein-ligand complexes are doable but tedious. Alternatively, we introduce efficient Delta S-vib estimates obtained by rigidity theory.

14:45

PELE: Low Cost Protein-Ligand Dynamics and Induced Fit
Victor Tasies, Research Professor, Barcelona Supercomputing Center, Spain

PELE (Protein Energy Landscape Exploration), combining protein structure prediction techniques with Monte Carlo sampling, allows the description of ligand dynamics at a fraction of the cost of molecular dynamics.

Computational Exploration of Transient Ligand-Binding Pockets and Tunnels in Proteins
Rebecca Wade, Group Leader, Heidelberg Institute for Theoretical Studies, Germany

The dynamic nature of protein structures provides challenges and opportunities for ligand design. I will describe computational approaches to identify and characterize transient ligand-binding pockets and tunnels in proteins and discuss their application in structure-based drug design.


Developments in Virtual Screening

16:30

Virtual and Experimental Fragment Screening on GPCRs
Gyorgy Keseru, Scientific Advisor, Hungarian Academy of Sciences, Hungary

The talk addresses the identification and optimization of fragment hits on GPCR targets using both in silico and experimental approaches. Hit finding strategies and early optimization of validated and specific hits will be discussed with case studies.

17:00

In Silico Screening for Novel Escort Molecules to Overcome Multidrug Resistance Efflux
Mire Zloh, Director of Structural Chemistry Unit, University College London, United Kingdom

Overcoming efflux pumps in multidrug resistance cell is a major challenge in treatment of infection, tumours and parasites. A novel in silico approach was developed to screen for escort molecules that could restore activity of a therapeutic.

Novel Approaches

09:00

Sir Tom BlundellKeynote Presentation

Structure Guided and Fragment Based Approaches to Drug Discovery to Targeting Protein-Protein Interactions
Sir Tom Blundell, Professor, University of Cambridge, United Kingdom

Detailed structural knowledge of complexes between macromolecules and their ligands – the structural interactome - can provide a rich source of information on the interaction between biological molecules. I will describe the application of fragment-based approaches to drug targets that involve protein-protein interactions.

09:30

Approaches to Address Protein Flexibility in Molecular Docking
Sander Nabuurs, Head Molecular Modelling and Computational Chemistry, Lead Pharma, Netherlands

An important but complex aspect of structure-based drug design is accurately modelling receptor flexibility. This contribution will focus on different approaches we have developed to address protein flexibility in modelling protein-ligand complexes. This ranges from the prediction of binding site plasticity to the improved ranking and scoring of induced fit docking solution utilizing protein structure validation techniques.

10:00

Novel Target Family-Centric Scaffolded Libraries Applying the Privileged Structure Concept: Unlocking the Kinase, PDE, GPCR, and Epigenetic Target Space
Gerhard Mueller, Senior Vice President, Mercachem BV, Netherlands

Novel privileged structure concepts are introduced to unlock the therapeutic value of most relevant target families, such as PDEs, GPCRs, kinases and epigenetic targets.

Computational Approaches for Predicting Targets and Side Effects of Bioactive Compounds
Didier Rognan, Director of Research, University of Strasbourg, France

Predicting the molecular targets responsible for the main side effects of lead compounds is nowadays affordable thanks to the increasing availability of target-ligand binding data and the development of computational approaches to mine and predict novel target-ligand associations.

ADMET Rationalisation and Prediction in Drug Discovery: Can Computational Chemistry Reduce Compound Attrition
Alexander Alex, Director, Alex Alexander Consulting, United States of America

Compound attrition is one of the major challenges in drug research, impacting productivity and preventing potential new chemical entities reaching the market. Understanding the factors which influence attrition as early as in the compound design stage prior to synthesis is critical for preventing potential ADMET liabilities in compound development. Therefore the effective utilisation of computational approaches to rationalise and predict potential ADMET issues early is crucial in assisting compound designers in understanding, preventing and managing compound attrition risk.

Automating QSAR Modelling to Drive Compound Design
Stephen Pickett, Manger, GlaxoSmithKline, United Kingdom

Development of local and global QSAR models remains a key requirement for many drug discovery programs; however increasing pressure on resources means that experts in specific statistical tools are not always available. Here we present the QSAR Workbench for building and managing QSAR models and describe how it is important to ensure appropriate experimental design within the program team to maximize the benefits of local QSARs.
