Chromogenic 3-Indoxyl choline phosphate compounds of formula (I):
1
wherein R is selected from the group consisting of hydrogen and C
1-4
alkyl, such as methyl, ethyl, propyl and butyl while R
1
, R
2
, R
3
, and R
4
are independently selected from the group consisting of hydrogen, halogen, cyano, nitro, carboxy, amino, amino substituted with one or two C
1-4
alkyl groups, aminomethyl, hydroxy, C
1-4
alkoxy, carboxyalkyl, and sulphonyl. These compounds are capable of being cleaved by lecithinase C leading to products which are calorimetrically detectable. The invention provides safe and sensitive detection of potentially pathogenic bacterial activity of such microbes as
Clostridium perfringens, Bacillus cereus, Bacillus anthracis, Pseudomonas aeruginosa, Listeria monocytogenes, Heliobacter pylori, Legionella pneumophila,
and others in material which may contain such activity typically including physiological samples, goods for consumption, such as food and beverages, and any other potentially infected objects or articles.

独立地选自氢、卤素、氰基、硝基、羧基、氨基、被一个或两个 C
1-4
烷基、氨基甲基、羟基、C
1-4
烷氧基、羧基烷基和磺酰基。这些化合物能够被卵磷脂酶 C 分解,生成可通过热量计检测的产物。本发明可安全、灵敏地检测潜在致病细菌的活性,这些微生物包括
产气荚膜梭菌、蜡样芽孢杆菌、炭疽杆菌、铜绿假单胞菌、李斯特菌、幽门螺旋杆菌、嗜肺军团菌、
及其他可能含有此类活性的物质,通常包括生理样本、食品和饮料等消费品以及任何其他可能受感染的物体或物品。
