Abstract:
Polyomines - particularly putrescine, spermidine and spermine - are ubiquitous components of eukaryote and most prokaryote cells, and are essential for optimal cell proliferation. But since routes of polyamine synthesis may differ, for example between parasites and their hosts, selective inhibition of polyamine metabolism offers an attractive target for chemotherapy - as already shown with the success of difluoromethylomithine (DFMO) as an inhibitor of polyamine synthesis in African trypanosomes. Parasitology Today has featured a series of articles reviewing research on polyamine metabolism of various parasites (eg. vol. 3, pp 190-192, pp 312-315; vol. 4, pp 18-20) and here, Nigel Yorlett discusses these metabolic aspects of Trichomonas vaginalis (Fig. 1)-a common parasite of the urogenital tract.
