Study Notes

Pharmacophore and QSAR

A pharmacophore is a set of features in a molecule that is responsible for its biological activity, essentially a 3D description of the molecular recognition process.

QSAR

QSAR stands for Quantitative Structure-Activity Relationship, a statistical approach to understand the relationship between a molecule's structure and its biological activity.

Drug Design

The main goal of drug design is to identify a molecule that binds to a specific target, such as a protein, to produce a desired therapeutic effect.

Pharmacophore Modeling

A key feature of pharmacophore modeling is the ability to identify the specific molecular features required for a molecule to bind to a target.

Limitations of QSAR

A limitation of QSAR modeling is that it relies on the availability of a large dataset of molecules with known biological activity, which can be a challenge in certain cases.

Goals of Drug Design

A goal of drug design is to optimize the binding affinity of a molecule to its target, thereby increasing its potency and efficacy.
