The invention concerns new aminoalkylmaleimides of the general formula I ##STR1## in which R.sub.1 and R.sub.2 are the same or different and represent hydrogen or a C.sub.1 -C.sub.4 alkyl group and A represents a straight-chain or branched, saturated or unsaturated alkylene group with 2 to 6 carbon atoms which is interrupted, if desired, by an oxygen or sulphur atom or a carbonyl group, as well as their corresponding acid addition salts. The present invention also concerns amidoalkylmaleimide derivatives formed from compounds of the general formula I and immunological binding partners. In addition, the invention concerns immunological conjugates which can be produced by reaction of the amidoalkylmaleimide derivatives with peptides or proteins. The subject matter of the present invention are also the corresponding processes of production of the compounds according to the present invention as well as the use of these conjugates in diagnostic methods of determination, in particular in immunoassays.
本发明涉及一类新的氨基酸烷基马来酰亚胺,其通式为I(##STR1##),其中R.sub.1和R.sub.2相同或不同,代表氢或C.sub.1 -C.sub.4烷基,A代表直链或支链、饱和或不饱和的亚烷基,含2至6个碳原子,如果需要,该亚烷基可被氧或硫原子或羰基团中断,以及它们的相应的酸加成盐。本发明还涉及由通式I的化合物形成的酰胺烷基马来酰亚胺衍生物和免疫学结合伴侣。此外,本发明还涉及可以通过酰胺烷基马来酰亚胺衍生物与肽或蛋白质反应产生的免疫学偶联物。本发明的主题还包括根据本发明生产化合物以及使用这些偶联物在诊断方法中,特别是在免疫分析中的相应过程。
