专利号:US-7799524-B2 优先权日:2002-10-03 标 题:Substrates for O6-alkylguanina-DNA alkyltransferase 发明人:KINDERMANN MAIK; JOHNSSON KAI; BIERI CHRISTOPH 权利人:ECOLE POLYTECHNIQUE FERDEALE D 摘要:The invention relates to compounds of formula 1 n nwherein R 1 -R 2 is a guanine derivative; X is oxygen or sulfur; R 3 is a heteroaromatic, unsaturated heterocyclyl or an alkynyl group with the double or triple bond connected to CH 2 ; R 4 is a linker; and L is a label, a plurality of same or different labels, a bond connecting R 4 to R 1 forming a cyclic substrate, or a further group —R 3 —CH 2 —X—R 1 -R 2 . The invention relates also to methods of manufacture of such novel AGT substrates, to intermediates useful in the synthesis of such AGT substrates, and to a method of transferring a label from such AGT substrates to O 6 -alkylguanine-DNA alkyltransferase (AGT) fusion proteins comprising proteins of interest.
