A known agent, [(5,6-dichloro-9a-n-propyl-2,3,9,9a-tetrahydro-3-oxo-1H fluoren-7-yl)oxy]acetic acid, which blocks
brain edema
, was also shown to be a potent cytotoxic agent in leukemia cells. The major site of action of the agents appears to be in the de novo purine synthetic pathway in L1210 leukemic cells. Both PRPP amido transferase and IMP dehydrogenase activities were suppressed by the agent. The inhibition of both regulatory enzymes of the pathway along with the reduction of
dihydrofolate reductase
activity would account for the observed suppression of DNA and RNA syntheses and subsequent cancer cell death.
