  Linker Length Modulates DNA Cross-Linking Reactivity and Cytotoxic Potency of C8/C8‘ Ether-Linked C2-exo-Unsaturated Pyrrolo[2,1-c][1,4]benzodiazepine (PBD) Dimers

  摘要：

  A C2/C2'-exo-unsaturated pyrrolo [2, 1-c] [1,4]benzodiazepine (PBD) dimer 4b (DRG-16) with a C8-O(CH2)(n)O-C8' diether linkage (n = 5) has been synthesized that shows markedly superior in vitro cytotoxic potency (e.g., > 3400-fold in IGROV1 ovarian cells) and interstrand DNA cross-linking reactivity (> 10-fold) compared to the shorter homologue 4a (SJG-136; n = 3). In contrast, for the C-ring unsubstituted series, the corresponding n = 5 dimer (3c) is generally less cytotoxic and has a lower interstrand cross-linking reactivity compared to its shorter n = 3 homologue (3a). Dimer 4b cross-links DNA with > 10-fold efficiency compared to 4a, and also inhibits the activity of the restriction endonuclease BamH1 more efficiently than either 3a or 4a. The C2-exo-unsaturated PBD dimers 4a,b are not only more effective than their C-ring saturated counterparts in terms of induced DeltaT(m) shift, but they also exert this effect more rapidly. Thus, while 3a and 3c exert 68 and 35% of their maximum effect immediately upon interaction with DNA, this level increases to 76 and 97% for 4a and 4b, respectively. Molecular modeling shows a rank order of 4b (n = 5) > 4a (n = 3) > 3a (n = 3) > 3c (n = 5) in terms of binding energy toward duplexes containing embedded target 5'-GAT(1-2)C cross-link sequences, reflecting the superior fit of the C2-exo-unsaturated rather than saturated C-rings of the PBD dimers. A novel synthesis of core synthetic building blocks for PBD dimers via stepwise Mitsunobu reaction and nitration with Cu(NO3)(2) is also reported.
