Watersoluble coumarin derivatives, their preparation and their use as enzyme substrates or for the preparation of those substrates.

摘要

Water-soluble coumarin derivatives. These derivatives correspond to the formula: <IMAGE> in which R<1> represents - (OCH2CH2)mOCH2R<7> or - (OCH(CH3)CH2)mOCH2R<7> with m = 1 to 30 and R<7> can be a hydrogen atom or various groups, R<2> to R<6> can be various substituents, in particular substituents which make it possible to introduce, into the derivative, a group which is suitable as an enzyme substrate or for the synthesis of enzyme substrates.
