Twenty-three arylthioureines bearing beta-alanine or gamma-aminobutyric alkyl ester chains were synthesized for in vitro screening toward 44 strains of fungi and 2 genera of nematodes. The nitro derivatives were the most potent compounds against Aspergillus and Candida strains. Ester chains increase activity against the filarial worm Molinema dessetae. Twelve compounds have EC(50) < 40 mu g/ml. However, the anthelmintic potency is weak compared with tetramisole.
