Dihydrofolate reductase, metotrexate®, marine sponges.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®.
