Abstract: Using ammonium thiocyanate, 2-chloro-4-chlorophenylformyl chloride, and 2-aminobenzoic acid as raw materials, a new type of acylthiourea derivative, N-(3-chlorobenzoyl)-N′-2-carboxybenzoyl thiourea (N-(3-chloro-benzoyl)-N′-2-carboxybenzoyl thiourea, CCT) was synthesized through a “one-step method”. The compound was characterized by single-crystal X-ray diffraction (SXRD), nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy (FT-IR), ultraviolet spectroscopy, and fluorescence spectroscopy. The SXRD results indicate that it belongs to the monoclinic crystal system, with the P21/c space group. Through multispectroscopy (ultraviolet absorption spectroscopy and fluorescence competitive substitution) combined with molecular docking technology, the interaction between the target thiourea and calf thymus DNA was determined. The results show that the two formed a complex in a groove interaction mode, without significantly disrupting the complete double helix structure of DNA. Hydrogen bonds are the main force.

Key words: thiourea derivative; crystal structure; calf thymus DNA; molecular docking
