The disclosure generally relates to compounds of formula (I), including their salts, as well as compositions and methods of using the compounds. The compounds are ligands, antagonists of the NR2B receptor and may be useful for the treatment of various disorders of the central nervous system.
Inhibitors of cyclic AMP phosphodiesterase. 2. Structural variations of N-cyclohexyl-N-methyl-4-[(1,2,3,5-tetrahydro-2-oxoimidazo[2,1-b]quinazolin-7-yl)oxy]butyramide (RS-82856)

steric bulk of substituents on the 1,2,3,5-tetrahydroimidazo[2,1-b]quinazolin-2-one heterocycle and the position and length of the side chain. As inhibitors of cyclic AMP phosphodiesterase (PDE), potency steadily increased with increasingly lipophilic side chains. In platelet aggregation inhibition studies, however, a maximum in activity was reached with 1, while more lipophilic compounds were significantly
Hapten synthesis, monoclonal antibody production and immunoassay development for direct detection of 4-hydroxybenzehydrazide in chicken, the metabolite of nifuroxazide
usually employed in immunoassay for detection of metabolites of nitrofurans and avoiding derivatization could be preferable to achieve an efficient screening. In the study, we designed four haptens of 4-hydroxybenhydrazide (HBH), the nifuroxazide metabolite. The effect of hapten structures on antibody affinity were evaluated and one monoclonal antibody was produced by using the Hapten C with a linear alkalane
免疫分析中通常采用衍生化方法检测硝基呋喃的代谢产物,避免衍生化可能是实现有效筛选的首选方法。在这项研究中,我们设计了4-羟基苯甲酰肼(HBH)(呋喃嗪叠氮化物)的四个半抗原。评估半抗原结构对抗体亲和力的影响,并通过使用带有线性烷烃间隔臂的半抗原C生产一种单克隆抗体。经过优化后,建立了一种酶联免疫吸附测定(ELISA),对HBH的抑制率为50%,浓度为0.25 ng mL -1,这可以确保直接检测HBH而无需衍生化。HBH ELISA的检测下限为0.12 µg kg -1回收率为90.1–96.2%,变异系数(CV)值低于9.1%。总之,我们用新设计的半抗原生产了几种针对HBH的高亲和力抗体,并开发了一种icELISA技术,可直接检测HBH而无需在鸡中衍生化。
