factors that help establish and maintain infection. Disruption of such secretion systems is a potentially effective therapeutic strategy. We developed a high-throughput screen and identified a tris-aryl substituted 2-imino-5-arylidenethiazolidin-4-one, compound 1, as an inhibitor of the type III secretion system. Expansion of this chemotype enabled us to define the essential pharmacophore for type III
多种致病性革兰氏阴性细菌利用分泌系统输出各种有助于建立和维持感染的蛋白质毒素和毒力因子。破坏这种分泌系统是一种潜在的有效治疗策略。我们开发了一个高通量的筛选器,并确定了三化合物被化合物1取代的三芳基取代的2-亚氨基5-芳基内酯-硫唑烷4-1,它是III型分泌系统的抑制剂。这种化学型的扩展使我们能够定义该结构类别用于抑制III型分泌的基本药效基团。合成多样性集帮助我们将N-3鉴定为最允许的基因座,并导致设计了一组具有改善的活性和理化性质的新型N-3-二肽修饰的同类物。现在,我们报告这些化合物的合成,
