Gefitinib
Descripción general
Descripción
Gefitinib, vendido bajo el nombre comercial Iressa, es un medicamento utilizado principalmente para el tratamiento de ciertos tipos de cáncer, incluido el cáncer de pulmón de células no pequeñas y el cáncer de mama. Es un inhibidor selectivo de la tirosina quinasa del receptor del factor de crecimiento epidérmico (EGFR), que juega un papel crucial en la regulación del crecimiento y la supervivencia celular .
Mecanismo De Acción
Gefitinib ejerce sus efectos inhibiendo la tirosina quinasa del EGFR. Se une al sitio de unión del trifosfato de adenosina (ATP) de la enzima, evitando la fosforilación y activación de las vías de señalización aguas abajo. Esta inhibición conduce a la supresión de la proliferación celular y la inducción de apoptosis en células cancerosas con EGFR sobreexpresado o mutado .

Mechanism of Action |
Gefitinib is an inhibitor of the epidermal growth factor receptor (EGFR) tyrosine kinase that binds to the adenosine triphosphate (ATP)-binding site of the enzyme. EGFR is often shown to be overexpressed in certain human carcinoma cells, such as lung and breast cancer cells. Overexpression leads to enhanced activation of the anti-apoptotic Ras signal transduction cascades, subsequently resulting in increased survival of cancer cells and uncontrolled cell proliferation. Gefitinib is the first selective inhibitor of the EGFR tyrosine kinase which is also referred to as Her1 or ErbB-1. By inhibiting EGFR tyrosine kinase, the downstream signaling cascades are also inhibited, resulting in inhibited malignant cell proliferation. |
