The invention relates to compounds of general structure (1 ): Q-(L1)n-(L2)o-(L3)p-(L4)q-D, wherein Q is a click probe; D is a cytotoxin containing an enediyne moiety; L1, L2, L3 and L4 are each individually linkers that together link Q to D; n, o, p and q are each individually 0 or 1, provided that n + o + p + q = 1, 2, 3 or 4, wherein D comprises a functional moiety (21), wherein R12 = C1-3-alkyl, the wavy line indicates the connection to the remainder of the cytotoxin, and wherein D is conjugated to (L4)q by replacing the amine H atom, and to conjugates obtainable by reacting the compound according to the invention with a protein comprising a click probe F capable of reacting with click probe Q in a click reaction. The invention further relates to a bioconjugate according to general structure (2): Pr-[(L6)-Z-(L1)n-(L2)o-(L3)p-(L4)q-D]xx, wherein Z is a connecting group that is formed in a click reaction, L6 is a linker that links Z to Pr and Pr is a (glyco)protein.
本发明涉及具有一般结构(1)的化合物:Q-(L1)n-(L2)o-(L3)p-(L4)q-D,其中Q是点击探针;D是含有环烯内酯基团的细胞毒素;L1、L2、L3和L4是单独的连接剂,它们共同将Q与D连接;n、o、p和q每个都是0或1,只要n + o + p + q = 1,2,3或4,其中D包含一个功能基团(21),其中R12 = C1-3-烷基,波浪线表示与细胞毒素其余部分的连接,并且D通过替换氨基H原子与(L4)q偶联,以及通过将根据本发明的化合物与包含能够与点击探针Q在点击反应中反应的点击探针F的蛋白质反应而得到的偶联物。本发明进一步涉及根据一般结构(2)的生物偶联物:Pr-[(L6)-Z-(L1)n-(L2)o-(L3)p-(L4)q-D]xx,其中Z是在点击反应中形成的连接组,L6是将Z与Pr连接的连接剂,Pr是(糖)蛋白质。
