A series of ester derivatives of1-benzy1-4-piperazineacetic acid was synthesized and evaluated as antiulcer agents. Quantitative structure-activity relationships (QSAR) analyses by using the ALS (adaptive least-squares) method were performed in each step to decrease the synthetic efforts. The QSAR for the esters is much the same as that for the previously examined amide derivatives. The antiulcer activity of these compounds was considered to be based on the cytoprotective activity. The most active and the least toxic compounds, 5n and 5y, were selected for further study.
合成了一系列1-苄基-4-哌嗪乙酸的酯衍生物,并评估其作为抗溃疡剂的效果。使用自适应最小二乘法(ALS)进行的定量结构-活性关系(QSAR)分析在每一步中都进行了,以减少合成工作。酯的QSAR与之前研究的酰胺衍生物的QSAR非常相似。这些化合物的抗溃疡活性被认为是基于其细胞保护活性。最活跃且毒性最低的化合物5n和5y被选中进行进一步研究。
