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

A C2/C2′-exo-unsaturated pyrrolo[2,1-c][1,4]benzodiazepine (PBD) dimer 4b (DRG-16) with a C8-O(CH2)nO-C8′ diether linkage (n = 5) has been synthesized that shows markedly superior in vitro cytotoxic potency (e.g., > 3400-fold in IGRO

Compounds of the formulae Ia and Ib: wherein:A is CH2, or a single bond;R2 is selected from: R, OH, OR, CO2H, CO2R, COH, COR, SO2R, CN;R6, R7 and R9 are independently selected from H, R, OH, OR, halo, amino, NHR, nitro, Me3Sn;and R8 is selected from H, R, OH, OR, halo, amino, NHR, nitro, Me3Sn, where R is as defined above, or the compound is a dimer with each monomer being the same or different and being of formula Ia or Ib, where the R8 groups of the monomers form together a bridge having the formula -X-R'-X- linking the monomers, where R' is an alkylene chain containing from 3 to 12 carbon atoms, which chain may be interrupted by one or more hetero-atoms and/or aromatic rings and may contain one or more carbon-carbon double or triple bonds, and each X is independently selected from O, S, or N; except that in a compound of formula Ia when A is a single bond, then R2 is not CH=CH(CONH2) or CH=CH(CONMe2).
