Abstract

We studied the effects of two N,N'-bis(benzyl)-substituted polyamine analogs on the capacities of Trypanosoma cruzi to invade and multiply within a mammalian host cell. At concentrations as low as 1 microM, these compounds reduced significantly the infectivity of the parasite for rat heart myoblasts in a time-dependent manner. Pretreatment of virulent T. cruzi trypomastigotes, but not myoblast pretreatment, reduced the level of infectivity. The inhibitory effects started to subside 3 h after removal of the drugs and were no longer detectable after 4 h. A significant decrease in the rate of intracellular amastigote multiplication was also seen when the drugs were added to myoblast cultures which had been previously infected with untreated T. cruzi. These results show that N,N'-bis(benzyl)-substituted polyamine analogs meet the two most important criteria for potential chemotherapeutic agents against T. cruzi infection, namely, inhibition of both host cell invasion and intracellular replication by this parasite.
