dehydrogenase/trypanothione reductase (GAPDH/TR). These enzymes belong to metabolic pathways that are vital to Trypanosoma brucei and Trypanosoma cruzi, and have thus been considered promising drug targets. The synthesized molecules were characterized for their dual‐target antitrypanosomal profile, both in enzyme assays and in in vitro parasite cultures. The merged derivative 2‐[3‐(3‐dimethylaminopropoxy)‐2‐oxo‐2H

crystallography. The complexes have a dicopper(II) unit with an alkoxo bridge from the Schiff base and the carboxylate, showing a three-atom bridging mode. The metal centres in a square planar CuNO3 coordination geometry are antiferromagnetically coupled in the asymmetrically double-bridged dicopper(II) core. A significant effect of the –CHCH–, –CH2– and –CH2CH2– spacers of the carboxylate ligands on the

5,7-dihydroxy-4-(4-hydroxyphenyl)-2H-1-benzopyran-2-one(1), 5,7-dihydroxy-3-(4-hydroxyphenyl)-2H-1-benzopyran-2-one(2) and their derivatives 3 - 6. It has been assigned a novel structure having the phenyl substituent in the benzenoid ring of the coumarin nucleus - 4,5-dihydroxy-7-(4-hydroxyphenyl)-2H-1-benzopyran-2-one(11).
