Gefitinib EP Impurity B with CAS No: 1603814-04-5 is an impurity standard of Gefitinib.
Gefitinib is a tyrosine kinase inhibitor used in the treatment of non-small cell lung cancer (NSCLC). Its application involves targeting and inhibiting the activity of the epidermal growth factor receptor (EGFR), a protein involved in the growth and division of cancer cells. Chemically, gefitinib is an anilinoquinazoline derivative. By disrupting the signaling pathways associated with EGFR, gefitinib impedes the uncontrolled growth of cancer cells. This targeted approach makes gefitinib an important therapeutic option in the management of NSCLC, particularly in cases where tumors exhibit specific EGFR mutations.
