✦ Synopsis
a c t Trypanosoma brucei and Trichomonas vaginalis are both parasitic protozoans that are known to share many similar biochemical pathways. Aristeromycin, as well as 5 0 -iodovinyl and 5 0 -oxime analogues of adenosine, are potent inhibitors of AdoHcy hydrolase in T. brucei, an enzyme that catalyses the hydrolysis of AdoHcy to adenosine and L-homocysteine. To help determine the role of this enzyme in T. vaginalis, we have tested a library of 5 0 -modified adenosine derivatives, including 5 0 -deoxy-5 0 -(iodomethylene)-adenosine and related 6-N-cyclopropyl analogues. Our results indicate that these inhibitors are effective at inhibiting the growth of T. vaginalis, by as much as 95%.
