Abstract

A novel series of extended DAPI analogues were prepared by insertion of either a carbon– carbon triple bond (16a–d) or a phenyl group (21a, b and 24) at position-2. The new amidines were evaluated in vitro against both Trypanosoma brucei rhodesiense (T. br) and Plasmodium falciparum (P. f.). Five compounds (16a, 16b, 16d, 21a, 21b) exhibited IC50 values against T. br of 9nM or less which is two to nine folds more effective than DAPI. The ...
