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

Design and synthesis of C-8 linked pyrrolobenzodiazepine-naphthalimide hybrids as anti-tumour agents

The facile synthesis of C-8 linked pyrrolobenzodiazepine-naphthalimide hybrid analogues is described. The compounds are prepared with varying degrees of linker length in order to probe the structural requirements for optimal in vitro anti-tumour activity. Some of these new hybrid compounds showed higher cytotoxic activity than the existing natural and synthetic pyrrolo[2,1-c][1,4]benzodiazepines.

Synthesis of novel non-cross-linking pyrrolobenzodiazepines with remarkable DNA binding affinity and potent antitumour activity

Mixed imine-amide pyrrolobenzodiazepine dimers have been prepared which exhibit potent antitumour activity and have significant DNA binding affinity; one of them, 1c, has been shown to cause a remarkable rise in the melting temperature of calf thymus DNA.

Synthesis of pyrrolo[2,1-c][1,4]benzodiazepine antibiotics: Oxidation of cyclic secondary amine with TPAP

A facile procedure for the preparation of the imine form of the pyrrolo(2,1-c][1,4]-benzodiazepine ring system by the oxidation of eyelid secondary amine with catalytic amounts of tetra-n-propylammonium perruthenate (TPAP) and N-methylmorpholine N-oxide (NMO) as a co-oxidant is described. This oxidative method is devoid of side-products and is thus a significant improvement over the Swern oxidation previously reported.

An efficient synthesis of pyrrolo[2,1-c][1,4]benzodiazepine antibiotics via reductive cyclization

A new and convenient one-pot synthesis of pyrrolo[2,1-c][1,4]benzodiazepine (PBD) ring system has been achieved by a reductive cyclization employing N,N-dimethylhydrazine and FeCl3.6H2O in good yields.

A new route for the synthesis of pyrrolo[2,1-c][1,4]benzodiazepine antibiotics via oxidation of cycle secondary amine

The synthesis of the imine-containing pyrrolo[2,1-c][1,4]benzodiazepine DNA-binding antitumour antibiotics was achieved by a new method of oxidation of cyclic secondary amines which does not endanger the stereochemical integrity of the C-11a position.

Synthesis of pyrrolo[2,1-c][1,4]benzodiazepine antibiotics via azido reductive cyclization with HMDST

A new facile synthesis of pyrrolo[2,1-c][1,4]benzodiazepine (PBD) ring system has been achieved by reductive cyclization of the azide employing hexamethyldisilathiane (HMDST). The parent unsubstituted PBD and the natural product DC-81 have also been prepared in good overall yields.

A new facile procedure for the preparation of pyrrolo[2,1-c][1,4]benzodiazepines : Synthesis of the antibiotic DC-81 and its thio analogue

An efficient synthesis of the imine form of the pyrrolo[2,1-c][1,4] benzodiazepine ring system based on a new reductive cyclization procedure is described. The naturally occuring antibiotic DC-81(5c) and its 5-thio analogue (7c) have also been synthesized to illustrate the usefulness of this methodology.
