Cobimetinib
Descripción general
Descripción
Cobimetinib, vendido bajo la marca Cotellic, es un medicamento contra el cáncer que se utiliza principalmente en combinación con vemurafenib para tratar el melanoma. Es un inhibidor selectivo de la quinasa 1 activada por mitógeno de proteína (MEK1) y la quinasa 2 activada por mitógeno de proteína (MEK2), que forman parte de la vía de la quinasa activada por mitógeno de proteína/quinasa regulada por señales extracelulares (MAPK/ERK) . Esta vía suele estar sobreactivada en diversos cánceres, lo que convierte a this compound en un valioso agente terapéutico .
Mecanismo De Acción
Cobimetinib es un inhibidor reversible de MEK1 y MEK2, que son reguladores ascendentes de la vía ERK . Al inhibir estas quinasas, this compound evita la fosforilación y activación de ERK, lo que conduce a una reducción de la proliferación celular y un aumento de la apoptosis en las células cancerosas . Este mecanismo es particularmente eficaz en los cánceres con mutaciones en el gen BRAF, que conducen a una activación constitutiva de la vía MAPK/ERK .

Mechanism of Action |
Cobimetinib is a reversible inhibitor of mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase 1 (MEK1) and MEK2. MEK proteins are upstream regulators of the extracellular signal-related kinase (ERK) pathway, which promotes cellular proliferation. BRAF V600E and K mutations result in constitutive activation of the BRAF pathway which includes MEK1 and MEK2. In mice implanted with tumor cell lines expressing BRAF V600E, cobimetinib inhibited tumor cell growth. Cobimetinib and vemurafenib target two different kinases in the RAS/RAF/MEK/ERK pathway. Compared to either drug alone, coadministration of cobimetinib and vemurafenib resulted in increased apoptosis in vitro and reduced tumor growth in mouse implantation models of tumor cell lines harboring BRAF V600E mutations. Cobimetinib also prevented vemurafenib-mediated growth enhancement of a wild-type BRAF tumor cell line in an in vivo mouse implantation model. |
