Abstract
Most of the memoxy-8H-dibenzo[a,g]isoquinolin-8-ones 3a-h and their acetoxy
derivatives 6a-e were synthesized by condensation of 1-oxo-1,2,3,4-tetrahydroisoquinolines
4a-c and homophthalic acid anhydrides 5a and b, ether
cleavage and acetylation. These protoberberinones were tested for cytostatic
activity in vitro using MDA-MB-231 mammary tumor cells and for interaction
with native calf thymus DNA. Tetramethoxy-8-oxoberbine 3f shows an
inhibition of cell proliferation of 87% at a concentration of 10-5 mole; its cytostatic effect does not depend on intercalation into DNA.
Die meisten der Methoxy-8H-dibenzo[a,g]chinolizin-8-one 3a-h und ihre
Acetoxyderjvate 6a-e wurden durch Kondensation der 1-Oxo-1,2,3,4-tetrahydroisochinoline
4a-c mit den Homophthalsäureanhydriden 5a und b, anschließende
Etherspaltung und Acetylierung dargestellt. Die cytostatische
Wirkung dieser Protoberberinone wurde an der MDA-MB-231-Zellinie, die
DNA-Interaktion an nativer Kalbsthymus-DNA geprüft. Das Tetramethoxy-
8-oxoberbin 3f zeigt eine Hemmung der Zellproliferation von 87% bei einer
Konzentration von 10-5 M, wobei die cytostatische Wirkung nicht auf eine
Interkalation mit der DNA zurückzuführen ist.
