摘要

Eighteen diamidino azaterphenyls and analogues were evaluated as anti-leishmanials; nine of the compounds gave IC50 values less than 1 mu M, five exhibited values less than 0.40 mu M, and two gave values less than 0.10 mu M in a Leishmania donovani axenic amastigote assay. The activity of the diamidines strongly depends on the ring N-atom location relative to the amidine groups and correlates with DNA affinity. Transmission electron microscopy studies showed a dramatic dilation of the mitochondrion and evidence of disintegration of the kinetoplast of the amastigotes.
