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

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

## Introduction to Small Molecule Inhibitors

Small molecule inhibitors have emerged as powerful tools in modern drug discovery and disease treatment. These compounds, typically with molecular weights below 900 daltons, can 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 and therapeutic development.

## The Science Behind Small Molecule Inhibition

Small molecule inhibitors work through several mechanisms:

– Competitive inhibition: Binding directly to the active site of an enzyme
– Allosteric inhibition: Binding to a site other than the active site to induce conformational changes
– Uncompetitive inhibition: Binding only to the enzyme-substrate complex
– Non-competitive inhibition: Binding to both free enzyme and enzyme-substrate complex
