aforementioned compound classes. Enantioresolution was achieved by simply adding native β‐cyclodextrin, acetyl‐β‐cyclodextrin, 2‐hydroxypropyl‐β‐cyclodextrin, or carboxymethyl‐β‐cyclodextrin as chiral selector additives to the background electrolyte. Fifty‐one chiral NPS served as analytes mainly purchased from online vendors via the Internet. Using 10 mM of the aforementioned β‐cyclodextrins in a 10 mM
The current invention provides an improved immunoassay for the detection and determination of pyrrolidinophenone based designer drugs in hair and biological fluids (urine, blood, and oral fluid). The generic immunoassay is underpinned by novel, sub-family-specific antibodies, which display surprising sensitivity. The invention further describes substrates comprising an antibody that is specific to compounds of the pyrrolidinophenone family. Also described are the novel immunogens from which the antibodies are derived and kits incorporating the antibodies of the current invention.

enantiomers may differ in their pharmacological effect. The aim of this study was to test a novel HPLCcolumn for the enantioseparation of a set of 112 NPS coming from different chemical groups and collected by internet purchases during the years 2010–2018. The CSP, namely Lux® 5 μm i‐Amylose‐1, LC Column 250 x 4.6 mm, was run in normal phase mode under isocratic conditions, UV detection was performed
这些术语背后隐藏着浴盐,熏蒸剂,清洁剂和空气清新剂,这些物质被算作“合法上限”。这些花哨的名字被用来装扮成合法的无害化合物,以规避市场营销的法律法规并增加销量。除了合成的经典非法药物(如苯丙胺,可卡因和摇头丸)以外,这些化合物的贸易(也称为新型精神活性物质(NPS))在当今并不罕见。在许多国家,NPS仍然不受药物管制。其中,有具有手性中心的兴奋剂,例如新的苯丙胺衍生物或卡西酮。关于两种可能的对映异构体的药理作用可能不同的事实知之甚少。这项研究的目的是测试一种新颖的HPLC色谱柱,该色谱柱用于对映分离2010年至2018年间通过互联网购买的来自不同化学族的112种NPS。CSP,即Lux®5μmi-Amylose-1,LC色谱柱250 x 4.6 mm,在等度条件下以正相模式运行,在245 nm和230 nm处进行UV检测,进样量为10μl,流速为为1毫升/分钟。使用由正己烷/异丙醇/二乙胺(90:10:0
