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 ...
