RESEARCH: CANCER
FOLDING PROJECT #18493 PROFILE

This project is trying out a new computer simulation method called 'expanded-ensemble' to predict how well drugs dissolve in water versus oily substances. This helps figure out if a drug will be effective because its solubility affects how much of the drug reaches the body.

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..

partition coefficient

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

The partition coefficient describes how well a substance dissolves in water compared to oil. It's important for drug development because it influences how easily a drug can pass through cell membranes and reach its target.

logP

Logarithm of the partition coefficient

logP is a shortened way to write the logarithm of the partition coefficient. It's used to predict how lipophilic (fat-soluble) a drug molecule is.

---

lipophilicity

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

Lipophilicity refers to how readily a substance dissolves in fats. Drugs that are too lipophilic may not be easily absorbed by the body, while those that are too hydrophilic (water-soluble) may not cross cell membranes effectively.

---

bioavailability

The proportion of a drug that reaches the systemic circulation.

Bioavailability describes how much of a drug actually enters the bloodstream and becomes available to act on its target. Several factors can affect bioavailability, including absorption, distribution, metabolism, and excretion.

simulations

Computer-based models that mimic real-world processes.

Simulations are used in drug discovery to predict the behavior of molecules and their interactions. This can help researchers design new drugs that are more effective and safer.

CPU

Central Processing Unit

The CPU is the brain of a computer, responsible for executing instructions and performing calculations.
