In this paper new kind of porphyrin compounds was prepared, which combined well the affinity of prophyrin to malignant tumour with anticancer of 5-fluorouracil porphyrin. The IR spectra of m- and p-chlorophenyl-5-fluorouracil prophyrin were obtained and analyzed. The IR absorption peaks were investigated and concluded in detail. The IR absorption rule of chloropenly-5-fluorouracil prophyrin which occurred when m-substitution and p-substitution appeared respectively on phenyl, and single substitution of N1 and double substitution of N1 appeared respectively on phenyl or N1 and N1, N3 positions on pyrimidine ring was also discussed. The results show that the relative intensity of nu c-o stretching vibration changed obviously by field-effect when the substitution was strong electro-negative group. Meanwhile, the IR spectral characteristics of the compounds mentioned above were revealed, and this can be used to deduce the stereochemistry structure of them.
本文制备了一种新型卟啉化合物,它将卟啉对恶性肿瘤的亲和力与5 - 氟尿嘧啶卟啉的抗癌性很好地结合起来。得到并分析了间氯苯基 - 5 - 氟尿嘧啶卟啉和对氯苯基 - 5 - 氟尿嘧啶卟啉的红外光谱。详细研究并总结了红外吸收峰。还讨论了苯基分别发生间位取代和对位取代,以及苯基上N1单取代、嘧啶环上N1单取代和N1、N3双取代时氯苯基 - 5 - 氟尿嘧啶卟啉的红外吸收规律。结果表明,当取代基为强电负性基团时,通过场效应,ν C - O伸缩振动的相对强度发生明显变化。同时,揭示了上述化合物的红外光谱特征,这可用于推断它们的立体化学结构。
