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(I)或(IA)的化合物中,X为H,Y为离开基团,R1和可选的R3优选为芳香族DNA结合亚基,是二元环霉素的前药类似物。这些化合物预计将在连接X的碳原子上被细胞色素P450,特别是CYP1B1水解,而在肿瘤中表达高水平。预计前药将优先在肿瘤细胞中被激活,从而作为DNA烷基化剂防止细胞分裂。
