Disclosed are compounds of the formula (I): wherein R
3
, R
4
, R
5
, R
9
, and R
10
are selected from the group consisting of H and groups or atoms other than H, and R
6
and R
8
are halo or hydrogen; X
1
, X
2
, and X
3
are independently O or S; provided that R
9
and R
10
are not simultaneously H, when all of X
1
, X
2
, and X
3
are O; and of the formula (II) wherein R
11
-R
14
are selected from the group consisting of H and groups or atoms other than H; X
4
-X
9
are independently O or S; n and m are 0 or 1 but m and n cannot be 0 simultaneously; R
15
-R
24
can be H or any substituent so long as the compound of formula II upon hydrolysis provides a fluorescent compound. These compounds are useful as substrates with high specificity for organophosphatase particularly human paraoxonase and bacterial organophosphorus hydrolase. Also disclosed is a method for detecting and/or measuring the paraoxonase activity in a fluid comprising contacting the fluid with a fluorescent substrate and measuring the fluorescence of the fluorescent product formed.
本发明涉及式(I)的化合物:其中R3、R4、R5、R9和R10选自H和除H以外的基团或原子,而R6和R8是卤素或氢;X1、X2和X3独立地是O或S;前提是当X1、X2和X3全为O时,R9和R10不能同时是H;以及式(II)的化合物:其中R11-R14选自H和除H以外的基团或原子;X4-X9独立地是O或S;n和m为0或1,但m和n不能同时为0;R15-R24可以是H或任何取代基,只要式II的化合物在水解后提供荧光化合物即可。这些化合物可用作具有高特异性的有机磷酸酯酶底物,特别是人类副氧化物酶和细菌有机磷酸酯水解酶。本发明还涉及一种检测和/或测量液体中副氧化物酶活性的方法,包括将液体与荧光底物接触,并测量形成的荧光产物的荧光强度。
