Descripción

Application

Potente inhibidor de la dihidrofolato reductasa y agente para estudios antitumorales. Se utiliza para inhibir la dihidrofolato reductasa en sistemas de expresión de proteínas basados en la DHFR. También eficaz en el tratamiento de los parásitos del paludismo Plasmodium vivax resistentes a la pirimetamina.

Potente inhibidor de la dihidrofolato reductasa y agente para estudios antitumorales. Se utiliza para inhibir la dihidrofolato reductasa en sistemas de expresión de proteínas basados en la DHFR. También muestra efectos inmunodepresores, por ejemplo en la artritis reumatoide

Biochem/physiol Actions

Methotrexate is an allosteric inhibititor of dihydrofolate reductase (DHFR), the enzyme that catalyzes the conversion of dihydrofolate to tetrahydrofolate. Since tetrahydrolfolate is required for purine and pyrimidine synthesis, methotrexate treatment results in the inhibition of DNA and RNA synthesis.
