A conjugate of formula (A):
where Y is selected from a single bond, and a group of formulae A1 or A2:
where N shows where the group binds to the N10 of the PBD moiety;
RL1 and RL2 are independently selected from H and methyl, or together with the carbon atom to which they are bound form a cyclopropylene group;
CBA represents a cell binding agent;
Q is independently selected from O, S and NH;
R11 is either H, or R or, where Q is O, SO3M, where M is a metal cation.
式(A)的共轭物:
其中 Y 选自单键和式 A1 或 A2 中的一个基团:
其中 N 表示基团与 PBD 分子的 N10 结合的位置;
RL1 和 RL2 独立地选自 H 和甲基,或与它们结合的碳原子一起形成环丙烯基团;
CBA 代表细胞结合剂;
Q 独立地选自 O、S 和 NH;
R11 是 H,或 R,或 Q 是 O 时是 SO3M,其中 M 是金属阳离子。
