The invention relates to a diaza-18-crown-6 derivative having formula (I): wherein: B is a moiety for a covalent bonding reaction; the two A are identical to each other and are a group of formula (II): where: n = 0 to 4; X1, X2, X3, X4 and X5 are N, a -CH group or a -CR group wherein R is a -P(O)(OR1)(OR2), -P(O)R1(OR2), -P(O)R1R2, -P(S)(SR1)(SR2), -P(S)R1(SR2) or -P(S)R1R2 group in which R1 and R2, identical or different, are H, or a C1-C4 alkyl group, provided that no more than two of X1, X2, X3, X4 and X5 are N and no more than one of X1, X2, X3, X4 and X5 is a -CR group. The invention also relates to a conjugate comprising the diaza-18-crown-6 derivative covalently bonded to a targeting moiety for biological cells, a chelate comprising radium chelated by the conjugate, and to uses of the diaza-18-crown-6 derivative, the conjugate and the chelate.
这项发明涉及具有以下式(I)的二氮杂-18-冠-6衍生物:其中:B是用于共价键合反应的基团;两个A相互相同,是式(II)的一个基团:其中:n = 0至4;X1、X2、X3、X4和X5是N、-CH基团或-CR基团,其中R是-P(O)(OR1)(OR2)、-P(O)R1(OR2)、-P(O)R1R2、-P(S)(SR1)(SR2)、-P(S)R1(SR2)或-P(S)R1R2基团,其中R1和R2,相同或不同,是H,或C1-C4烷基基团,前提是X1、X2、X3、X4和X5中不超过两个是N,且X1、X2、X3、X4和X5中不超过一个是-CR基团。该发明还涉及将二氮杂-18-冠-6衍生物共价键合到生物细胞靶向基团的共轭物,包括由该共轭物螯合的镭的螯合物,以及二氮杂-18-冠-6衍生物、共轭物和螯合物的用途。
