Identification of Novel IGF1R Kinase Inhibitors by Molecular Modeling and High-Throughput Screening

Area of Science:

• Pharmacology
• Medicinal Chemistry
• Molecular Biology

Background:

• The insulin-like growth factor 1 receptor (IGF1R) is a key target for cancer therapy.
• Existing experimental anti-IGF1R therapeutics face challenges, necessitating the development of novel drug candidates.
• Identifying compounds with superior properties is crucial for advancing IGF1R-targeted treatments.

Purpose of the Study:
