RESEARCH: DRUG-SOLUBILITY-PREDICTION
FOLDING PROJECT #12473 PROFILE

This project explores using computer simulations to predict how well drugs dissolve in water compared to fats (logP). Different simulation settings are tested to see which ones work best.

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 the solubility of a compound in two immiscible solvents.

The partition coefficient is a scientific term used to describe how well a molecule dissolves in different types of liquids. It's often used in drug development to predict how easily a drug will move between the blood and other tissues in the body. A higher partition coefficient means the molecule dissolves better in fats or oils, while a lower coefficient means it dissolves better in water.

logP

Logarithm of the partition coefficient

logP is a shorthand way to express the partition coefficient. It's used in drug development to predict how well a drug will move through the body and how likely it is to be absorbed.

---

lipophilicity

The solubility of a substance in lipids (fats) compared to its solubility in water.

Lipophilicity describes how well a molecule dissolves in fats and oils compared to water. It's important in drug development because drugs need to be able to cross cell membranes, which are made up of fat molecules.

---

bioavailability

The proportion of a drug that reaches the systemic circulation.

Bioavailability refers to how much of a drug actually reaches the bloodstream and can have an effect in the body. It's influenced by factors like how the drug is taken (e.g., orally, intravenously) and its lipophilicity.

forcefield

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

A forcefield is like a set of rules that govern how atoms behave in a computer simulation. These rules help scientists predict how molecules will interact and move.

expanded-ensemble (EE) simulations

A type of molecular simulation that uses a larger number of configurations to improve the accuracy of predictions.

Expanded-ensemble simulations are a more sophisticated way of simulating molecules in computer programs. By looking at many different ways a molecule can be arranged, they can make more accurate predictions about how it will behave.
