Structures of various ICLs. a B-DNA and the ICLs formed by b cisplatin, c psoralen, d BCNU and e acetaldehyde and crotonaldehyde viewed from the major groove (left) or the minor groove (right). The crosslinked bases and the crosslinking agents are shown in red. Structures taken from PDB, accession numbers: B-DNA (1-BNA) [140], cisplatin (1A2E) [13], psoralen (204D) [21], BCNU (2MH6) [23], acetaldehyde (2HMD) [29]
