FOLDING PROJECT #12464 PROFILE

This project is figuring out if computer simulations can predict how well drugs dissolve in the body. It's testing different simulation methods and seeing if the choice of software affects the results. This helps scientists design better medicines!

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 coefficient, 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 easily a substance dissolves in both water and oil. It's essential for understanding drug absorption and distribution within the body. A higher partition coefficient indicates greater solubility in oil, which can influence a drug's ability to cross cell membranes.

logP

Logarithm of the partition coefficient

logP is a simplified way to express the partition coefficient. It's often used in drug development to predict how well a molecule will dissolve in fat versus water. Higher logP values generally indicate better absorption into tissues.

lipophilicity

The tendency of a substance to dissolve in lipids (fats).

Lipophilicity describes how much a molecule prefers to dissolve in fats compared to water. It's crucial for drug effectiveness because many drugs need to pass through lipid membranes to reach their targets within the body.

bioavailability

The proportion of a drug that reaches the systemic circulation.

Bioavailability refers to how much of a drug actually enters the bloodstream after administration. Factors like solubility and metabolism can influence bioavailability.

forcefield

A set of parameters used in computer simulations to model the interactions between atoms in molecules.

Forcefields are like mathematical rules that govern how atoms behave in simulations. They're essential for accurately predicting the movement and interactions of molecules.
