The invention concerns a novel chromogenic substrate based on Alizarin. The invention also concerns the uses to which this substrate can be put, and a formulation containing such a substrate.
It consists therefore of a substrate to detect the presence of an enzyme activity, with the following general formula:
1
in which:
the two ketone groups of the central ring can be replaced by one group R
11
(in the upper position), and by OH (in the lower position).
R
1
is a target part or H, and R
2
is a target part or H, with at least one out of R
1
and R
2
being a target part,
R
3
is H, SO
3
H, Cl, Br, F, I, NO
2
, NH
2
, NR

R
10
, or an Acylamino Aminoaryl or Aminoacylamino group of the type NHCOX, with X being an Alkyl, Aryl or Aralkyl group or an a-amino acid residue such as Alanine,
R4 is H, SO
3
H, Cl, Br, F, I, NO
2
, NH
2
, NR
9
R
10
, OH or an Acylamino Aminoaryl or Aminoacylamino group of the type NHCOX, with X being an Alkyl, Aryl or Aralkyl group or an &agr;-amino acid such as Alanine,
according to a modification, R
3
and R
4
form bonds with one another to create a ring with at least five sides, and preferably six sides.
R
5
, R
6
, R
7
and R
8
each consist of one of the following atoms or groups of atoms: H, a halogen (particularly Cl or Br), OH, SO
3
H, or an Alkyl or Alkoxy group, and
R
9
a R
10
are independently a Methyl, Alkyl, Aryl, Aralkyl group, or one (either R
9
or R
10
) is a ring structure (Piperidine, Pyrrolidine, Morpholine, etc.) with the other (either R
10
or R
9
) being a Hydrogen atom.
The invention is particularly applicable in the field of diagnosis.
这项发明涉及一种基于茜素的新型显色底物。该发明还涉及可以应用此底物的用途,以及含有这种底物的配方。因此,它包括一种用于检测酶活性存在的底物,具有以下一般公式:其中:中心环的两个酮基团可以被一个R11基团(在上部位置)和一个OH基团(在下部位置)取代。R1是目标部分或H,R2是目标部分或H,其中至少有一个是目标部分,R3是H、SO3H、Cl、Br、F、I、NO2、NH2、NR9R10或NHCOX类型的Acylamino Aminoaryl或Aminoacylamino基团,其中X是Alkyl、Aryl或Aralkyl基团或α-氨基酸残基,如丙氨酸,R4是H、SO3H、Cl、Br、F、I、NO2、NH2、NR9R10、OH或NHCOX类型的Acylamino Aminoaryl或Aminoacylamino基团,其中X是Alkyl、Aryl或Aralkyl基团或α-氨基酸,如丙氨酸,根据一种修改,R3和R4相互形成键,创建至少五边形,最好是六边形的环。R5、R6、R7和R8分别由以下原子或原子团组成:H、卤素(特别是Cl或Br)、OH、SO3H或Alkyl或Alkoxy基团,而R9和R10独立地是甲基、Alkyl、Aryl、Aralkyl基团,或者其中之一(R9或R10)是环结构(哌啶、吡咯烷、吗啉等),而另一个(R10或R9)是氢原子。该发明在诊断领域特别适用。
