RTK Inhibitor Library: A Comprehensive Collection for Targeted Therapy Research

Receptor tyrosine kinases (RTKs) play a crucial role in cellular signaling pathways, regulating processes such as cell growth, differentiation, and survival. Dysregulation of RTKs is often associated with various cancers and other diseases, making them attractive targets for therapeutic intervention. The RTK Inhibitor Library provides researchers with a comprehensive collection of compounds designed to modulate these critical signaling molecules.

Understanding RTKs and Their Importance

RTKs are a family of cell surface receptors that transmit signals from extracellular growth factors to intracellular pathways. When activated by ligand binding, RTKs initiate a cascade of phosphorylation events that ultimately influence gene expression and cellular behavior. Abnormal RTK activity, whether through overexpression, mutations, or autocrine stimulation, can lead to uncontrolled cell proliferation and survival – hallmarks of cancer.

The RTK family includes well-known members such as:

• EGFR (Epidermal Growth Factor Receptor)
• VEGFR (Vascular Endothelial Growth Factor Receptor)
• PDGFR (Platelet-Derived Growth Factor Receptor)
• FGFR (Fibroblast Growth Factor Receptor)
• c-Met
