Abstract

SQ 18,506 is a nitrofuran compound related to the trypanocide Lampit. In vitro, radiolabeled leucine, uridine, and thymidine were incorporated into macromolecular protein, RNA, and DNA in order to study growth inhibition of Trypanosoma cruzi. Our findings suggest that the primary effect of the drug is on protein synthesis and not mediated solely by inhibition of RNA synthesis as indicated by prior studies. The drug was also found to reduce markedly the uptake of uridine into the nucleotide precursor pool but to affect only slightly the formation of aminoacyl-tRNA.
