# Small Molecule Inhibitors from MuseChem: Targeting Key Pathways in Disease

## Introduction to Small Molecule Inhibitors

Small molecule inhibitors have become indispensable tools in modern drug discovery and biomedical research. These compounds, typically with molecular weights below 900 daltons, are designed to specifically bind to and modulate the activity of target proteins involved in disease pathways. MuseChem has established itself as a leading provider of high-quality small molecule inhibitors for research applications across various therapeutic areas.

## The Science Behind Small Molecule Inhibition

The principle behind small molecule inhibitors lies in their ability to bind to specific sites on target proteins, often at catalytic or allosteric sites, thereby modulating their function. This binding can:

– Block enzymatic activity
– Disrupt protein-protein interactions
– Alter protein conformation
– Prevent post-translational modifications

MuseChem’s collection includes inhibitors targeting kinases, proteases, epigenetic regulators, and other classes of disease-relevant proteins.
