DNA binding potential and cytotoxicity of newly designed pyrrolobenzodiazepine dimers linked through a piperazine side-armed-alkane spacer

New pyrrolobenzodiazepine (PBD) dimers have been developed that are composed of two DC-81 subunits tethered to their C8 positions through piperazine moiety side-armed with alkaneoxy linkers (composed of 2-5 carbons). DNA thermal denaturation studies show

Synthesis, DNA binding ability and anticancer activity of 2-heteroaryl substituted benzimidazoles linked pyrrolo[2,1-c][1,4]benzodiazepine conjugates

As a continuation of our efforts to develop the benzimidazole-PBD conjugates as potential anticancer agents, a series of heteroaryl substituted benzimidazole linked PBD conjugates has been synthesized and evaluated for their anticancer potential in 60 human cancer cell lines. Most of the compounds exhibited promising anticancer activity and interestingly, compounds 4c and 4d displayed significant activity in most of the cell lines tested. Whereas, compound 4e showed selectivity in renal cancer cells with GI50 values of 10 and 70 nM against RXF 393 and UO-31 cell lines, respectively. Further, these compounds also showed significant DNA-binding affinity by thermal denaturation study using duplex form of calf thymus (CT) DNA.

Design, synthesis, and evaluation of new noncross-linking pyrrolobenzodiazepine dimers with efficient DNA binding ability and potent antitumor activity

New sequence selective mixed imine-amide pyrrolobenzodiazepine (PBD) dimers have been developed that are comprised of DC-81 and dilactam of DC-81 subunits tethered to their C8 positions through alkanedioxy linkers (comprised of three to five and eight car

Synthesis of C-8 alkylamino substituted pyrrolo[2,1-c][1,4]benzodiazepines as potential anti-cancer agents

The design and facile synthesis of C-8 alkylamino substituted pyrrolo[2,1-c][1,4]benzodiazepines is described. These have been prepared by linking the amines at C-8 position with propane spacer to improve solubility in water, and their in vitro cytotoxici
