es with N-substituted maleimides. The compounds were screened for their antibacterial activities and most of them exhibited activity against Enterococcus faecalis (ATCC 29212) and Staphylococcus aureus (ATCC 25923). cis-3a and cis-3d were found fairly effective against E. faecalis (ATCC 29212) and S. aureus (ATCC 25923) with MIC values of 25 and 50microg/ml. With the changes of cis isomers of the compounds
2,3,5-取代的全氢吡咯并[3,4-d]异恶唑-4,6-二酮(44种化合物)的合成已通过N-甲基-C-芳基亚硝基与N-取代的马来酰亚胺的环加成反应完成。筛选了化合物的抗菌活性,并且大多数化合物表现出对粪肠球菌(ATCC 29212)和金黄色葡萄球菌(ATCC 25923)的活性。发现cis-3a和cis-3d对屎肠球菌(ATCC 29212)和金黄色葡萄球菌(ATCC 25923)相当有效,MIC值为25和50microg / ml。随着化合物顺式异构体的转变,其抗菌活性也随之改变。首先,已经根据电子拓扑方法(ETM)的规则计算了药效学片段。下一个,活性化合物和药效基团都已被投影到Kohonen自组织图(SOM)的节点上,以获取药效基团片段的权重作为数值描述符,此后用于关联神经网络(ASNN)训练。作为训练ASNN的结果,开发了用于活动预测的模型。
