According to the result, we believed that the reason resulted in the low sensitivity was that the marker residue compound MQCA structure has changed after conjugated with protein and the antibody induced by the conjugation could not recognize the free MQCA in the ci-ELISA. Therefore we designed some hapten which could reserve the marker residue structural speciality mostly. After synthesis route selection and optimum, the hapten 7-Hydroxymethyl-3-methyl-quinoxaline-2-carboxylic acid was synthesized, used 4-methyl-2-nitroaniline as the start material via six steps, such as oxidation cyclization, bromize reaction, hydrolysis, Beirut reaction, reduction, hydrolysis. This work established basis for producing the high affinity antibody and developing the sensitive ELISA residue detection method.

本论文认为导致ELISA检测灵敏度较低的原因，是残留标示物和蛋白偶联后的特征结构发生改变，诱导产生的抗体不能够对游离MQCA很好的识别，因此，本论文设计了能够最大化保留MQCA结构特征的系列半抗原结构，并对其合成路线进行了筛选和优化，最终以对甲基邻硝基苯胺为起始原料，经氧化环化、溴代、水解、Beirut缩合、还原、水解六步反应制备含羟甲基结构的MQCA衍生物7-羟基甲基-3-甲基-喹噁啉-2-羧酸，为制备对游离残留标示物高亲和力的抗体，高灵敏度的ELISA残留检测方法的建立奠定基础。

A new organic compound, trans-2--5-dimesitylborylthiophene (abbreviated as DMASBT, 5) with dimesitylboryl, dimethylamino and styryl-thiophene as electron acceptor, electron donor and conjugate bridge respectively, was synthesized. Its crystal structure determined by X-ray diffraction method indicates that the B-C bond between B atom and it bridge is obviously shorter than those of between B atom and mesityl groups. This remarkably strengthened B-C bonding can be regarded as an evidence of additional p-7t conjugation between the B atom and n bridge.
