摘要: 以硫氰酸铵、间氯苯甲酰氯、邻氨基苯甲酸为原料,通过“一步法”合成了新型酰基硫脲衍生物N-(3-氯苯甲酰基)-N′-2-羧基苯甲酰基硫脲(N-(3-chloro-benzoyl)-N′-2-carboxy benzoyl thiourea, CCT),采用单晶X射线衍射(SXRD)、核磁共振波谱、傅里叶变换红外光谱(FT-IR)、紫外光谱及荧光光谱等手段进行表征,SXRD结果表明其为单斜晶系,P21/c空间群。通过多光谱学(紫外吸收光谱及荧光竞争取代)结合分子模拟对接技术,测定了目标硫脲与小牛胸腺DNA的相互作用,结果表明二者以沟槽作用方式形成了复合物,基本没有破坏DNA完整的双螺旋结构,氢键为其主要作用力。

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
