Gefitinib

Sinónimos: Iressa, ZD1839, 4-(3-chloro-4-fluorophenylamino)-7-methoxy-6-(3-morpholinopropoxy)quinazoline, N-(3-chloro-4-fluorophenyl)-7-methoxy-6-(3-morpholin-4-ylpropoxy)quinazolin-4-amine

Gefitinib has become a mainstay in the targeted treatment of non-small cell lung cancer (NSCLC), particularly for patients whose tumors harbor EGFR mutations. As the first EGFR tyrosine kinase inhibitor approved for clinical use, it continues to drive steady demand from generic drug manufacturers, CDMO partners, and research institutions worldwide.

Chemically, gefitinib is a synthetic anilinoquinazoline derivative. It works by reversibly binding to the ATP-binding site of the epidermal growth factor receptor (EGFR) tyrosine kinase domain, blocking autophosphorylation and downstream signaling that fuels tumor cell proliferation. This mechanism makes it a valuable tool both as an active pharmaceutical ingredient (API) and as a reference standard in bioequivalence and pharmacological studies.

LyvBio supplies gefitinib with a purity of ≥99.0% (HPLC), meeting stringent pharmacopeial requirements. Our material is manufactured under cGMP conditions and is available for immediate shipment from stock, serving formulation development, clinical trial supply, and commercial production needs.

Descripción general y composición del producto

Gefitinib is a small-molecule kinase inhibitor belonging to the quinazoline class. It is practically insoluble in water but dissolves readily in organic solvents such as DMSO, which is typical for this chemical family. The compound is stable under normal storage conditions and is typically handled as a fine crystalline powder.

Our gefitinib API is produced through a multi-step synthesis followed by recrystallization to achieve high chemical purity. Each batch is tested for identity, assay, and impurity profile to ensure consistency and compliance with ICH guidelines. The material is non-hygroscopic and shows good flow properties, making it suitable for tablet and capsule formulations.
