1H-pyrrolo[2,3-f]quinoline and isoquinoline derivatives: synthesis and antiproliferative activity.

Fischer indol synthesis is reported for the preparation of some 2-substituted 1H-pyrrolo[2,3-f]quinoline and isoquinoline derivatives having a structural correlation with naturally occurring compound ellipticine. The prepared compounds proved capable of forming in vitro molecular complexes with native double-stranded DNA by intercalation between two base pairs and showed a relatively good activity in inhibiting the DNA synthesis in Ehrlich ascites tumor cells.

Pyrrolocoumarin derivatives: DNA-binding properties.

The spectroscopic and DNA-binding properties of a number of pyrrolocoumarin derivatives, including linear tricyclic, angular tricyclic, linear tetracyclic and angular tetracyclic compounds were investigated. The compounds we examined form non-covalent complexes with duplex DNA, probably of the intercalation type. The binding constants are comparable with the constants found for the furocoumarin analogues. Although for some of the compounds the photoreactivity with DNA is comparable with that of 8-MOP, pyrrolocoumarins behave as monofunctional reagents. This fact is explained in terms of an increased delocalization of the 4',5' double bond in the pyrrole moiety. Denaturation-renaturation experiments and HPLC analysis of the photoadducts confirm that pyrrolocoumarins are essentially monofunctional DNA-photobinding agents.
