RESEARCH: HALOGENASES
FOLDING PROJECT #19204 PROFILE

Many drugs use halogens (like fluorine or chlorine). Adding these can be tricky because it's hard to control where they go. The project relates to using computer models to predict how well different enzymes can add halogens to molecules in a controlled way, helping scientists design safer and more effective drugs.

Note: This TLDR is a simplication and may not be 100% accurate.

Approximately 40 percent of drugs approved or currently in clinical testing contain halogens (F, Cl, Br, or I) as pharmaceutically active ligand substituents.

This makes the halogenation of chemical scaffolds an issue of particular interest to medicinal chemists when attempting to synthesize potential drug candidates.

Many of the current methods for halogenation are difficult to control the regioselectivity or produce toxic byproducts during the reaction.

Due to these issues; halogenases, a class of enzymes that catalyze highly regioselective halogenation of various molecules in nature, have been studied as a means to improve existing halogenation methods with less toxic byproducts and higher regioselectivity of reaction.

By utilizing Relative Binding Free Energy calculations (RBFE) across a number of common organic molecule scaffolds, our goal is to better predict the probability and site of halogenation for various common chemical scaffolds across a number of halogenases.

Halogens

Elements in Group 17 of the periodic table (F, Cl, Br, I).

Halogens are highly reactive elements commonly used in pharmaceuticals. They can be incorporated into drug molecules to modify their properties and activity.

Ligand

A molecule that binds to a specific receptor or site.

Ligands are molecules that bind to target sites in the body, often proteins, to exert their effects. In drug development, ligands are designed to interact with specific receptors to produce desired therapeutic outcomes.

Halogenation

The process of adding a halogen atom to a molecule.

Halogenation is a chemical reaction that introduces a halogen atom into an organic molecule. This process can alter the molecule's properties and reactivity, making it useful in drug development.

Relative Binding Free Energy (RBFE)

A computational method used to predict the binding affinity of a molecule to a target.

RBFE calculations are used in drug design to assess how well a molecule binds to its intended target. By simulating molecular interactions, scientists can identify potential drug candidates with high binding affinity.
