    • The present invention provides phospholipase substrates of the general formula: ##STR1## wherein A is an alkylene or alkenylene radical containing up to 16 carbon atoms, R is a hydrgen atom or an alkyl, alkenyl or acyl radical containing up to 20 carbon atoms or an optionally alkyl-substituted aryl or aralkyl radical containing up to 8 carbon atoms in the alkyl moiety, X is the residue of an aromatic hydroxy or thiol compound and each Y, independently of one another, is an oxygen or sulphur atom and Z is --SO.sub.3.sup..crclbar. or a radical of the general formula: ##STR2## wherein R.sup.1 can be a hydrogen atom or a radical of the general formula --(CH.sub.2).sub.n NR.sub.3.sup.2, in which n is 2, 3 or 4 and R.sup.2 is a hydrogen atom or a methyl radical, or is an inositol or serine (--CH.sub.2 --CH(NH.sub.2)--COOH) or glycerol residue.The present invention also provides a process for the optical determination of phospholipases using these substrates, as well as a reagent containing them.
    • 本发明提供以下通式的磷脂酶底物:其中A是含有至多16个碳原子的亚烷基或亚烯基,R是氢原子或烷基,烯基或 含有至多20个碳原子的酰基或在烷基部分含有至多8个碳原子的任选的烷基取代的芳基或芳烷基,X是芳族羟基或硫醇化合物的残基,每个Y彼此独立地是 氧原子或硫原子,Z为-SO 3( - )或下式通式的基团:其中R 1可以是氢原子或通式为 - (CH 2)n NR 33的基团,其中n为2, 3或4,R2为氢原子或甲基,或为肌醇或丝氨酸(-CH2-CH(NH2)-COOH)或甘油残基。 本发明还提供了使用这些底物光学测定磷脂酶的方法以及含有它们的试剂。
