In vitro studies in exponentially growing L1210 cells utilizing DNA flow cytometry and cell proliferation measurements indicate enhancement of methotrexate effects by Dipyridamole provided: Methotrexate concentrations exceed those required to shut off maximally de novo pathways of purine and pyrimidine synthesis (i.e. 30 nM for 48 h), and Dipyridamole concentrations exceed 3 microM. In 10% fetal calf serum, this concentration inhibits tritiated thymidine uptake by about 80%. These data should prove helpful in the planning of clinical studies with dipyridamole or other inhibitors of nucleoside transport used to potentiate inhibitors of de novo pathways.
