Fluorogenic compounds are disclosed which are reactive with biologically important analytes including primary amines, secondary amines, and/or thiols and are of the general formula: ##STR1## wherein X is a group such as ##STR2## --CN, --CO.sub.2 CH.sub.3, or SO.sub.2 R, and wherein R is OR.sub.3, or Cl; R.sub.1 and R.sub.2 are hydrogen atoms or alkyl groups having 1 to 3 carbon atoms and R.sub.3 is a phenyl or benzyl group. The inventive compounds form a fluorescent adduct with the above analytes at the number 7 position of the benzoxadiazole ring. The fluorescent adduct thereby formed enables detection of very minute amounts of analyte (picomoles) using conventional fluorescent analytical methods.
公开了与生物重要分析物反应的荧光化合物,包括一级胺,二级胺和/或巯基,其通用式为:##STR1## 其中X是如##STR2##,-CN,-CO.sub.2 CH.sub.3或SO.sub.2 R的基团,其中R是OR.sub.3或Cl; R.sub.1和R.sub.2是具有1到3个碳原子的氢原子或烷基,R.sub.3是苯基或苄基。这些创新性化合物在苯并噁唑环的7号位置与上述分析物形成荧光加合物。由此形成的荧光加合物使用常规荧光分析方法可以检测到非常微小的分析物(皮克摩尔)。
