Synthesis and in Vitro Antitumor Activity of Phenanthrolin-7-one Derivatives, Analogues of the Marine Pyridoacridine Alkaloids Ascididemin and Meridine: Structure−Activity Relationship
10]-phenanthrolin-7-ones, analogues of the marine pyridoacridines meridine and ascididemin, have been synthesized on the basis of Diels-Alder reactions involving different quinoline-5,8-diones and N,N-aldehyde-dimethylhydrazones. All the compounds were evaluated for in vitro cytotoxic activity against 12 distinct human cancer cell lines. They all exhibit cytotoxic activity with IC(50) values at least

ascididemin, bromoleptoclinidinone, neocalliactine acetate, and 11-hydroxyascididemin, based on a Brønsted acid-promoted tandem annulation has been developed. Alkyne building blocks were first designed and then employed in alkaloid synthesis; these building blocks can be accessed by a Sonogashira coupling reaction on a multigram scale.

Marine compounds with pyridoacridine skeletons are known to exhibit interesting antitumor activities. Among these compounds, meridine has already been reported as having significant antitumor activities in vitro. We synthesized 24 analogues of meridine substituted on ring A with the aim of obtaining compounds that display significantly higher in vitro antitumor activities than meridine. The 24 compounds
