Abstract

The efficacy of a series of aurones, auronols and 4-methoxy-α-pyrones has been screened for the ability to inhibit the intracellular growth of the parasitic protist Cryptosporidium parvum using an in vitro enzyme linked immunosorbent assay (ELISA). All aurones of this series were active at 25 to 100 μM. 10 of 19 aurones inhibited the intracellular growth of C. parvum by > 90 % with moderate to no toxicity. The most active of these was 3′,4′,6-trihydroxy-2-[phenylmethylene]-3(2H)-benzofuranone.
