Synthesis, antifungal and nematocidal activities of thioureines with an aminoester sequence
摘要:
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.

The reaction of molecular bromine (Br2) with arylthioureas is known to produce 2-aminobenzothiazoles (Hugerschoff reaction). We show here that benzyltrimethylammonium tribromide (1, PhCH2NMe3Br3), a stable, crystalline organic ammonium tribromide (OATB), can be readily utilized as an alternative electrophilic bromine source. It is easier to control the stoichiometry of addition with an OATB, which
