Grossularine-1 and grossularine-2, cytotoxic α-carbolines from the tunicate: Dendrodoa grossularia

  title={Grossularine-1 and grossularine-2, cytotoxic $\alpha$-carbolines from the tunicate: Dendrodoa grossularia},
  author={C. Moquin-Pattey and M. Guyot},
Abstract Several indole derivatives were isolated from the tunicate: Dendrodoa grossularia among which two α-carbolines: grossularine-1 (revised structure) and grossularine-2. The structures were based upon spectral data, including X-ray analysis for grossularine-2. These compounds exhibit marked cytotoxicity toward murine and human tumor cells. They are the first example of naturally occurring α-carbolines.

Grossularine-1 and grossularine-2, alpha carbolines from Dendrodoa grossularia, as possible intercalative agents.
Results of viscometry, fluorescence quenching and DNA melting experiments clearly indicated the intercalative properties of grossularine-2 explained by its quasi-planar structure and the non-intercalative DNA binding of grossularityine-1 explained by the presence of a bulky indole chain at the 2-position of the alpha-carboline ring.

Effects of 9-OH-ellipticine on cell survival, macromolecular syntheses, and cell cycle progression in sensitive and resistant Chinese hamster lung cells.
The results show that 9-OH-E toxicity on sensitive and resistant cells involves different mechanisms of action: the drug toxicity in the sensitive cells appears to result from lethal lesions mediated through the interaction of the drug with an intracellular protein, independently of any effect of theDrug on the macromolecular syntheses; in the resistant cells, the cell death occurs concomitantly with the inhibition of these syntheses.
