Antitumour chemotherapy is nowadays a very active field of research, DNA targeting drugs being the most widely used group in therapy. The design, synthesis and anticancer activity of a new class of anticancer derivatives with pyrrolo-1,2-diazine and benzoquinone skeleton is presented. The synthesis is direct and efficient, involving an alkylation followed by a [3+2] dipolar cycloaddition. The penta- and tetra-cyclic pyrrolo-1,2-diazine were evaluated for their in vitro anticancer activity against an NCI 60 human tumour cell line panel. The pentacyclic-1,2-diazine exhibit a significant anticancer activity against Non-Small Cell Lung Cancer NCI-H460, Leukemia MOLT-4, Leukemia CCRF-CEM and Breast Cancer MCF7. We hypothesize that these molecules will exert their anticancer activity through multiple mechanisms of action: intercalating the DNA, inhibiting the topoisomerase enzymes and, destroying the DNA strands via electron transfer mechanism. However, the intercalation with the DNA seems to prevail in competition with the others mechanisms.

UI MeSH Term Description Entries
D008958 Models, Molecular Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures. Molecular Models,Model, Molecular,Molecular Model
D011724 Pyridazines Six-membered rings with two adjacent nitrogen atoms also called 1,2-diazine.
D011758 Pyrroles Azoles of one NITROGEN and two double bonds that have aromatic chemical properties. Pyrrole
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
