Compounds of the general formula I or IA or a salt in which X is H, Y is a leaving group, R

preferably being an aromatic DNA binding subunit are prodrug analogues of duocarmycin. The compounds are expected to be hydroxylated at the carbon atom to which X is joined, by cytochrome P450, in particular by CYP1B1, expressed at high levels in tumours. The prodrug is expected to be activated preferentially in tumour cells, where it will act as a DNA alkylating agent preventing cell division.

通式为I或IA的化合物,或其中X为H,Y为离去基团,R1最好是芳香族DNA结合亚基的盐是杜卡霉素的前药类似物。预计这些化合物将在与X相结合的碳原子上被细胞色素P450,特别是CYP1B1水解,而CYP1B1在肿瘤中表达水平高。预计前药将优先在肿瘤细胞中被激活,它将作为DNA烷基化剂防止细胞分裂。
