与非选择性临床使用的药物相比,γ-氨基丁酸A型受体(GABA A R)的亚基选择性调节被认为产生的副作用更少。在这里,β2/ 3亚基选择性GABA A R调节剂戊烯酸(VA)和洛雷唑(LOR)指导了结构简化的新型亚基选择性配体的合成。我们使用两个微电极电压钳技术研究了它们对非洲爪蟾卵母细胞中表达的GABA A Rs的影响。与VA和LOR相比,五种化合物显示出对GABA诱发的电流的调制显着更有效,并且保留了效力和选择性。化合物18 [(E)-2–氰基-3-(2,4-二氯苯基)丁-2-烯酰胺]诱导了最大的GABA诱导的氯离子电流调制(E max:3114±242%),而12 [(Z)-3 -(2,4-二氯苯基)丁-2-乙腈]显示出最高的效价(EC 50:13±2μM)。此外,在海马神经元中12促进了阶段性和强直性GABA的抑制作用,并且体内研究显示,与戊二醛和LOR相比,抗戊烯四唑(PTZ)诱

The present invention relates to a pharmaceutical composition for use as a medicament and to the use of the pharmaceutical composition for modulating the response of a GABAA receptor and the treatment of conditions like insomnia, anxiety, cardiac disease and/or epilepsy. Furthermore, the present invention refers to new active agents suitable for said pharmaceutical compositions.
Organic compounds showing the ability to inhibit effector toxin secretion or translocation mediated by bacterial type III secretion systems are disclosed. The disclosed type III secretion system inhibitor compounds are useful for combating infections by Gram-negative bacteria such as
Salmonella
spp.,
Shigella flexneri, Pseudomonas
spp.,
Yersinia
spp., enteropathogenic and enteroinvasive
Escherichia coli
, and
Chlamydia
spp. having such type III secretion systems.
