evaluated as anti-virulence agents for the treatment of gastritis and gastric ulcer caused by Helicobacter pylori. In vitro enzyme-based screen together with in vivo assays and structure−activity relationship (SAR) studies led to the discovery of three potent urease inhibitors 3-(3,5-dichlorophenylamino)N-hydroxypropanamide (3a), 3-(2-chlorophenylamino)N-hydroxypropanamide (3d) and 3-(2,4-dichlorophenylam
设计,合成和评估了一系列新型的含苯胺的异羟肟酸,作为抗毒剂,用于治疗幽门螺杆菌引起的胃炎和胃溃疡。基于体外酶的筛选以及体内测定和结构活性关系(SAR)研究导致发现了三种有效的脲酶抑制剂3-(3,5-二氯苯基氨基)N-羟基丙酰胺(3a),3-(2-氯苯基氨基)N-羟基丙酰胺(3d)和3-(2,4-二氯苯基氨基)N-羟基丙酰胺(3n)。化合物3a,3d和3n表现出优异的脲酶抑制作用,IC 50值为0.043±0.005、0.055±0.008和0.018±0.002μM,并且在32 mg / kg bid剂量下显着抑制了胃炎的发展,根除幽门螺杆菌的比率达到92.3、84.6和100%,分别。初步安全性研究(对小鼠的急性毒性)显示,LD 50分别为2982.8、3349.4和3126.9 mg / kg的KM小鼠对3a,3d和3n的耐受性良好。总体而言,本研究中获得的数据表明3a,3d和3n,尤

The present invention relates to novel bicyclic thiazoles of formula (I) which are positive allosteric modulators of the metabotropic glutamate receptor subtype 5 ("mGluR5") and which are useful for the treatment or prevention of disorders associated with glutamate dysfunction and diseases in which the mGluR5 subtype of receptors is involved. The invention is also directed to pharmaceutical compositions comprising such compounds, to processes for preparing such compounds and compositions, and to the use of such compounds and compositions for the prevention and treatment of disorders in which mGluR5 is involved.
This disclosure provides compounds and methods of using those compounds to treat metabolic disorders and hyperproliferative disorders, including administration of the compounds in conjunction with hormone receptor antagonists.
