RESEARCH: DRUG-SOLUBILITY-PREDICTION
FOLDING PROJECT #18497 PROFILE

This project tests using computer simulations to predict how well drugs dissolve in water versus oil. The project looks at different simulation methods and how they affect 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 solvents.

The partition coefficient describes how readily a molecule dissolves in water compared to oil. It's a crucial factor in determining drug effectiveness as it influences how well a medication can pass through cell membranes and reach its target.

logP

Logarithm of the octanol-water partition coefficient

logP is a simplified way to represent the partition coefficient. It's a numerical value that indicates how much more soluble a drug is in fat (octanol) compared to water. Higher logP values suggest better solubility in fats, which can influence how easily a drug crosses cell membranes.

lipophilicity

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

Lipophilicity is a key property that affects how well drugs can move through the body. Drugs with high lipophilicity are more likely to dissolve in cell membranes, allowing them to enter cells and exert their effects.

---

bioavailability

The fraction of a drug that reaches the systemic circulation.

Bioavailability refers to how much of a drug actually enters the bloodstream and becomes available to act on its target. Several factors can influence bioavailability, including lipophilicity, metabolism, and absorption.

forcefield

A set of mathematical equations that describe the interactions between atoms in a molecule.

Forcefields are essential for computer simulations of molecules. They allow scientists to predict how molecules will behave and interact with each other. Different forcefields have varying levels of accuracy and are suited for different types of calculations.
