ACTIVIDAD INHIBITORIA SOBRE LA ENZIMA DIHIDROFOLATO REDUCTASA DE EXTRACTOS DE ESPONJAS MARINAS DEL GOLFO DE URABÁ INHIBITORY ACTIVITY OF SOME MARINE SPONGE EXTRACTS FROM URABÁ GULF ON DIHYDROFOLATE REDUCTASE ENZYME

ACTIVIDAD INHIBITORIA SOBRE LA ENZIMA DIHIDROFOLATO REDUCTASA DE EXTRACTOS DE ESPONJAS MARINAS DEL GOLFO DE URABÁ INHIBITORY ACTIVITY OF SOME MARINE SPONGE EXTRACTS FROM URABÁ GULF ON DIHYDROFOLATE REDUCTASE ENZYME

Abstract

RESUMEN: La enzima dihidrofolato reductasa está implicada en la producción de la base pririmidínica timidina, componente esencial de la estructura del ADN. Por tanto, cualquier sustancia que la inhiba tiene como efecto la inhibición de la síntesis del ADN, y es potencialmente útil para el tratamiento de varios tipos de cáncer como leucemias linfoblásticas. En este trabajo se determina el grado de inhibición que los extractos etanólicos obtenidos de las esponjas marinas colombianas Svenzea zeai, Amphimedon compressa, Ircinia campana, Aplysina archeri, Xestospongia proxima y Xestospongia muta, presentan sobre la enzima purificada de origen humano dihidrofolato reductasa. Los resultados muestran que la mayoría de los extractos de estas esponjas inhiben esta enzima. Estos resultados se comparan con los del medicamento usado contra el cáncer, Metotrexate®, el cual se utiliza como control de inhibición de los ensayos y se observa que algunas de las esponjas tienen mayor inhibición que este medicamento.

ABSTRACT: Dihydrofolate reductase is an enzyme involved in the production of pyrimidinic base timidin, a structural component of DNA, therefore whatever substance that inhibit this enzyme inhibit the DNA synthesis as a consequence and it can be potentially useful as a treatment of several types of cancer like lymphoblastic leukemias. In this work we determinate the inhibition grade that the ethanol extracts from Colombian marine sponges: Svenzea zeai, Amphimedon compressa, Ircinia campana, Aplysina archeri, Xestospongia proxima y Xestospongia muta, over the human purified enzyme dihydrofolate reductase. The results shown that most of marine sponge extracts inhibite the enzyme. Results are compared with methotrexate® a medicament used against cancer which is used as a control for the bioassays. Results demonstrate that some of the analyzed extracts have more inhibition than the control metotrexate
