Structure-based drug design is advancing allosteric drug discovery. Allosteric sites offer unique advantages for developing selective and tolerable therapeutics by leveraging protein flexibility and function.
Area of Science:
- Pharmacology and Medicinal Chemistry
- Structural Biology
- Drug Discovery
Background:
- Growing interest in allosteric sites for novel therapeutic development over the past 20 years.
- Allosteric sites offer greater selectivity and tolerability compared to orthosteric sites due to lower conservation across protein families.
Purpose of the Study:
- To examine the impact of structure-based drug design (SBDD) on allosteric drug discovery.
- To highlight key targets across various classes where SBDD is influencing allosteric therapeutic strategies.
Main Methods:
- Review and analysis of current structure-based drug design approaches applied to allosteric targets.
- Examination of protein flexibility and its role in allosteric site function and drug design.
Main Results:
- Structure-based drug design principles are being adapted to address the unique challenges of allosteric sites.
- Understanding protein flexibility is crucial for successful allosteric drug design.
- Several examples demonstrate the impact of SBDD on diverse allosteric targets.
Conclusions:
- Structure-based drug design is a significant and growing influence in the field of allosteric drug discovery.
- Further research into protein dynamics will enhance the development of selective allosteric therapeutics.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
Protein-Drug Binding: Determination Methods
Indirect methods involve isolating the bound drug from its free form in biological samples such as blood, serum, or plasma. These techniques aim to measure the percentage of drugs bound to proteins. Equilibrium dialysis is a commonly used method where the free drug concentration at equilibrium is measured by separating the bound...
