The small molecule compound erlotinib is a receptor tyrosine kinase inhibitor that competes with adenosine triphosphate to bind to the catalytic site of the intracellular region of the receptor tyrosine kinase in cells, thereby inhibiting the phosphorylation reaction and thereby blocking the phosphorylation reaction. It has proliferation signaling, inhibits the activity of tumor cell ligand-dependent HER-1/EGFChemicalbookR, and achieves the effect of inhibiting tumor cell proliferation. Erlotinib is also another tyrosine kinase inhibitor used in the treatment of NSCLC. The results of clinical phase I trials show that its main toxicity and side effects are dose-dependent rash and diarrhea, and other rare side effects are headache, nausea and vomiting.
