摘要

We have developed a novel type of DNA interstrand cross-linking agent by synthesizing dimers of a pyrrole (Py)/imidazole (Im)-diamide-CPI conjugate, ImPyLDu86 (1), connected using seven different linkers. The tetramethylene linker compound, 7b, efficiently produces DNA interstrand cross-links at the nine-base-pair sequence, 5'-PyGGC (T/A) GCC Pu-3', only in the presence of a partner triamide, ImImPy. For efficient cross-linking by 7b with ImImPy, ...
