title: Synthesis, phytotoxic, cytotoxic, acetylcholinesterase and butrylcholinesterase activities of N,N'-diaryl unsymmetrically substituted thioureas.
abstract: Fourteen N,N'-diaryl unsymmetrically substituted thioureas were synthesised and their cytotoxic (in vitro), phytotoxic (in vitro), acetylcholinesterase and butrylcholinesterase activities were determined. Thiourea 16 exhibited high, and 1 and 3 showed significant phytotoxic activity. Thioureas 1, 3, 4, 6 and 10 showed significant activity and 2, 6 and 7 indicated moderate cytotoxic activities. Compound 12 exhibited butrylcholinesterase activity higher than a standard reference.
