# Small Molecule Inhibitors in Drug Discovery and Development

Introduction to Small Molecule Inhibitors

Small molecule inhibitors have become a cornerstone in modern drug discovery and development. These compounds, typically with molecular weights below 900 Daltons, are designed to specifically target and modulate the activity of proteins involved in disease pathways. MuseChem has emerged as a leading provider of high-quality small molecule inhibitors for research and therapeutic applications.

Mechanistic Action of Small Molecule Inhibitors

Small molecule inhibitors work through various mechanisms to regulate biological processes:

• Competitive inhibition by binding to active sites
• Allosteric modulation of protein conformation
• Disruption of protein-protein interactions
• Stabilization of specific protein conformations

Applications in Drug Discovery

The use of small molecule inhibitors spans across multiple therapeutic areas:

Oncology

Kinase inhibitors have revolutionized cancer treatment by targeting specific signaling pathways in tumor cells.

Infectious Diseases

Viral protease inhibitors have become essential components of antiviral therapies.

Neurological Disorders

Small molecules targeting neurotransmitter systems offer potential treatments for conditions like Alzheimer’s and Parkinson’s diseases.

Advantages of Small Molecule Inhibitors

Compared to biologics, small molecule inhibitors offer several benefits:

• Oral bioavailability
