N-Benzoyl-N'-carboxyl substituted thiourea derivatives (I-X) have been synthesized by the reaction of benzoyl isothiocyanate with amino acids. Their structures are confirmed by IR, (HNMR)-H-1, and elemental analysis. The reaction conditions are experimentally investigated, and the preliminary biological tests show that some of the compounds have excellent plant growth promotion activities.

at 181.328 ppm for (C=S), 170.308 ppm and 168.680 ppm for two (C=O) and aromatic carbons at 133.56-128.954 ppm. The MALDI-TOF-MS results showed presence of molecular ion peaks at appropriate positions. Antimicrobial activity results showed that TH-01, TH-08 and TH-09 have promising antibacterial potential against K. pneumoniae (12 mm) and P. aeruginosa (16 mm and 14 mm) respectively. The DPPH radical
