| 摘要 |
The present invention provides phospholipase substrates of the general formula: <IMG> (I) or <IMG> (II) wherein A is an alkylene or alkenylene radical containing up to 16 carbon atoms, R is a hydrogen 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 -SO3 ? or a radical of the general formula: <IMG> wherein R1 can be a hydrogen atom or a radical of the general formula -(CH2)nR?, in which n is 2, 3 or 4 and R2 is a hydrogen atom or a methyl radical, or is an inositol or serine (-CH2-CH(NH2)-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.
