( A) The platinum atom of DDP binds covalently to the N7 position of guanine. ( B) An interstrand crosslink is formed when DDP binds to two bases from different strands. On the other hand, an intrastrand adduct is formed when DDP binds to two bases of the same strand.
WebOct 1, 2016 · The most noteworthy and well characterized metallodrug found to bind DNA is cis -diamminedichloroplatinum (II) (cisplatin). Cisplatin, the first inorganic chemotherapeutic, was discovered serendipitously by Barnett Rosenberg in 1965 while studying the effects of electric fields on Escherichia coli using a platinum electrode [21].
