RESEARCH: CANCER
FOLDING PROJECT #12465 PROFILE

This project explores using computer simulations to predict how well drugs dissolve in water versus fat. This 'logP' value is important because it affects how well a drug works in the body. Researchers are testing different simulation methods and seeing if different computer models impact the accuracy of these predictions.

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 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

Measure of a substance's solubility in two immiscible solvents.

The partition coefficient describes how well a substance dissolves in oil compared to water. It's crucial for understanding how drugs will move through the body because it affects their absorption and distribution.

---

logP

Logarithm of the partition coefficient

logP is a simplified way to represent the partition coefficient. A higher logP value means a substance is more soluble in oil and less soluble in water.

---

lipophilicity

The tendency of a substance to dissolve in lipids or fats.

Lipophilicity describes how well a substance mixes with fats. Drugs need the right balance of lipophilicity to be absorbed into the bloodstream and reach their target tissues.

---

bioavailability

The proportion of a drug that reaches the bloodstream.

Bioavailability measures how much of a drug actually makes it into the body's circulation. Factors like lipophilicity influence bioavailability.

---

forcefield

A set of parameters used in molecular simulations.

Forcefields are like rules that govern how atoms interact with each other in computer simulations. They help researchers predict the behavior of molecules.

simulations

Computer models of chemical processes.

Simulations allow researchers to study molecules and their interactions without needing physical experiments. They can be used to predict properties like solubility.
