RESEARCH: DRUG-SOLUBILITY-PREDICTION
FOLDING PROJECT #12471 PROFILE

This project explores using computer simulations to predict how well drugs dissolve in water versus oil (a measure called logP). LogP is important because it affects how much of a drug reaches its target in the body. The project tests different simulation methods and looks at how choosing the right simulation tools impacts the results.

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

A key challenge in computational drug discovery is developing and testing methods to predict experimental partition coefficients for the relative solubility of organic molecules in aqueous vs.

non-polar media.

The logarithm of the partition coeffient, logP, is an important predictor of lipophilicity, which dictates the bioavailability of drugs.

This CPU project is testing expanded-ensemble (EE) simulations as a method for the calculation of logP and seeing if forcefield selection effects these calculations..

partition coefficient

A measure of a substance's solubility in two immiscible liquids.

The partition coefficient describes how well a molecule dissolves in water compared to another solvent, often oil. It helps predict how a drug will move through the body and reach its target.

---

logP

Logarithm of the partition coefficient

logP is a simplified way to express the partition coefficient. A higher logP value means a molecule prefers to dissolve in oil rather than water.

---

lipophilicity

The ability of a molecule to dissolve in fats and oils.

Lipophilicity is important for drug absorption and distribution. Highly lipophilic drugs can cross cell membranes easily but may be slower to clear from the body.

---

bioavailability

The proportion of a drug that reaches the bloodstream.

Bioavailability determines how much of a drug is available to have an effect. Factors affecting bioavailability include absorption rate and metabolism.

---

forcefield

A set of parameters used to describe the interactions between atoms in a molecular simulation.

Forcefields are essential for accurately simulating the behavior of molecules. They define how atoms attract or repel each other and influence their movement.

simulations

Computer models that mimic real-world processes.

Simulations are used to study complex systems like drug interactions. They can predict how molecules will behave in different environments.
