Abstract: Eleven new arylureido-acylthiourea derivatives have been synthesized by solid phase grinding under solvent-free conditions at room temperature. Their structures were confirmed by 1H NMR, IR and elementary analysis. The results of biological activity tests show that some target compounds have evident activity on plant growth when the concentration is 10 mg/L. Among these, N-phenylureido-N′-cinnamic acylthiourea and N-p-methylphenylureido N′-cinnamic acylthiourea have good auxins activity, the effects are 54.13% and 46.79%, respectively, while N-p-methylphenylureido-N′-cinnamic acylthiourea and N-p-methylphenylureido-N′-phenoxyacetyl thiourea have excellent activity of cytokinin, the effects are 55.11% and 51.14%, respectively.

Key words: arylureido-acylthiourea, solid phase grinding synthesis, biological activity
