# RTK Inhibitor Library: A Comprehensive Collection for Targeted Kinase Research

## Introduction to RTK Inhibitors

Receptor tyrosine kinases (RTKs) play a crucial role in cellular signaling pathways that regulate essential biological processes such as cell growth, differentiation, and survival. The RTK Inhibitor Library represents a valuable resource for researchers investigating these important molecular targets in various disease contexts, particularly cancer.

## What is the RTK Inhibitor Library?

The RTK Inhibitor Library is a carefully curated collection of small molecules designed to selectively inhibit various receptor tyrosine kinases. This comprehensive library includes:

– Well-characterized inhibitors targeting specific RTK families
