Various skin test reagents supplying minor determinants for detecting penicillin hypersensitivity have been examined by high-performance liquid chromatography (HPLC) for composition and stability. HPLC systems capable of separating and determining the four diastereoisomers of benzyl-D-penicilloic acid and the two benzyl-D-penicilloic acids were developed for this purpose. The "simple skin test reagent
已通过高效液相色谱(HPLC)检查了各种可提供检测青霉素超敏性次要决定因素的皮肤测试试剂的成分和稳定性。为此目的,开发了能够分离和确定苄基-D-青霉酸的四种非对映异构体和两种苄基-D-青霉酸的HPLC系统。由老化的青霉素的部分碱性水解产物组成的“简单皮肤测试试剂”可能是(5R,6R)-苄基-D-青霉酸酯的适当来源,而由皮肤的老化水溶液组成的“简单皮肤测试试剂”青霉素是该化合物的可疑来源。改良的Levine,Voss,Redmond和Zolov次要决定簇混合物(MDM)试剂及其组分(5R,已经发现6R)-苄基-D-苄基乙酸酯和(5R)-苄基-D-苄基乙酸酯在水溶液中非常不稳定,从而产生非对映异构体的混合物。在C-5上差向异构化的趋势是(5R,6S)-和(5S,6R)-以及(5R,6R)-苄基-D-青霉烯酸的突出特征。MDM试剂以干燥的冻干粉剂的形式制成单剂量安瓿瓶,可干燥保存,无需更改,可根
