A new class of stable dioxetanes bears a polycyclic stabilizing group and aryloxy moiety, the oxygen atom of which is provided with a protective group which can be removed by an enzymatic or chemical trigger admixed with the dioxetane. The polycyclic stabilizing group is preferably spiroadamantane. The group further bears an alkoxy, aryloxy, aralkyloxy or cycloalkyloxy moiety which is partially or completely substituted with halogens, particularly fluorine and chlorine. Proper selection of electron active groups on the stabilizing moiety, the aryl group and the OR group yields enhanced enzyme kinetics, superior light intensity and excellent detection sensitivity in various assays.
一种新型稳定的二氧杂环烷类化合物,其具有多环稳定基团和芳氧基团,其中氧原子带有保护基团,该保护基团可以通过酶或化学触发剂与二氧杂环烷混合后去除。多环稳定基团优选为螺环戊烷基团。该基团进一步带有烷氧基团、芳氧基团、芳基烷氧基团或环烷氧基团,部分或完全被卤素,特别是氟和氯取代。在稳定基团、芳基和OR基团上适当选择电子活性基团,可在各种检测中提高酶动力学、光强度和检测灵敏度。
