Gefitinib

Light-Yellow Crystalline PowderGefitinib was introduced in Japan as a daily oral monotherapy for the treatment of inoperable or recurrent non-small cell lung cancers (NSCLC). This anilinoquinazoline derivative can be synthesized in 6 steps starting from 6,7-dimethoxyquinazolin-4(3H)-one by successive monodemethylationlacetylation of the 6-hydroxy-group followed by chlorination and reaction with 3-chloro-4-fluoroaniline, finally deacetylation and alkylation with 3-(4-morpholinyl)propylbromi
Solid
Gefitinib is a member of the class of quinazolines that is quinazoline which is substituted by a (3-chloro-4-fluorophenyl)nitrilo group, 3-(morpholin-4-yl)propoxy group and a methoxy group at positions 4,6 and 7, respectively. An EGFR kinase inhibitor used for the treatment of non-small cell lung cancer. It has a role as an epidermal growth factor receptor antagonist and an antineoplastic agent. It is an aromatic ether, a member of monochlorobenzenes, a member of monofluorobenzenes, a secondary amino compound, a tertiary amino compound, a member of quinazolines and a member of morpholines.|Gefitinib (originally coded ZD1839) is a drug used in the treatment of certain types of cancer. Acting in a similar manner to erlotinib (marketed as Tarceva), gefitinib selectively targets the mutant proteins in malignant cells. It is marketed by AstraZeneca under the trade name Iressa.|Gefitinib is a Kinase Inhibitor. The mechanism of action of gefitinib is as a Protein Kinase Inhibitor.|Gefitinib is a selective tyrosine kinase receptor inhibitor used in the therapy of non-small cell lung cancer. Gefitinib therapy is associated with transient elevations in serum aminotransferase levels and rare instances of clinically apparent acute liver injury.|Gefitinib is an anilinoquinazoline with antineoplastic activity. Gefitinib inhibits the catalytic activity of numerous tyrosine kinases including the epidermal growth factor receptor (EGFR), which may result in inhibition of tyrosine kinase-dependent tumor growth. Specifically, this agent competes with the binding of ATP to the tyrosine kinase domain of EGFR, thereby inhibiting receptor autophosphorylation and resulting in inhibition of signal transduction. Gefitinib may also induce cell cycle arrest and inhibit angiogenesis. (NCI04)|A selective tyrosine kinase inhibitor for the EPIDERMAL GROWTH FACTOR RECEPTOR (EGFR) that is used for the treatment of locally advanced or metastatic NON-SMALL CELL LUNG CANCER.
