Attic Molecular Discovery Lab: A Virtual Tour Through Drug Development

Molecular Docking

In the Attic Molecular Discovery Lab, you engage with the process of molecular docking, where small molecules or ligands are positioned to fit into a protein's binding site. This is governed by Lennard-Jones interactions for van der Waals forces, Coulomb interactions for electrostatic effects, and hydrogen bonding for specific chemical attractions. These forces collectively determine the stability and specificity of the interaction.

Understanding these interactions is crucial in drug development as it helps predict how well a molecule will bind to its target protein, which can lead to effective therapeutic agents or inhibitors.

Dose-Response Fitting

The dose-response relationship is another critical aspect of the lab. By fitting IC50 values from serial dilutions with pipetting errors, you learn how varying concentrations of a compound affect its biological response. The IC50 value represents the concentration at which half maximal effect occurs and is essential for determining the potency of a drug.

This process involves statistical analysis to account for experimental variability, ensuring that the data accurately reflect the true dose-response relationship.

Energy Minimisation

To ensure accurate models of molecular interactions, energy minimization techniques are used. This involves relaxing a molecule's structure using Verlet dynamics to find its lowest energy configuration. This step is vital for predicting the most stable and biologically relevant conformation of molecules.

By minimizing energy, researchers can better understand how molecules behave in different environments, which is crucial for drug design and understanding protein-ligand interactions.

Cell Counting

In the lab, you also practice counting cells using Poisson statistics. This method helps quantify cell populations accurately, especially when dealing with small sample sizes or low cell densities. The Poisson distribution is particularly useful for modeling rare events and provides a probabilistic framework to estimate cell counts.

Cell counting is fundamental in many biological assays, from assessing the efficacy of drugs on cellular systems to monitoring bacterial growth.
