    摘要: Disclosed are the compounds Asamarine A and B, novel cytotoxic diterpene-alkaloids, that have been isolated from the sponge Raspailia sp. The structure of these compounds have been established on the basis of NMR data and confirmed by X-ray analysis. Also disclosed are compounds (I) and (II), wherein wherein R1 represents hydrogen or lower alkyl or lower alkanoyl; R2 represents hydrogen or lower alkyl; R3 is either an alkyl or a cycloalkyl group containing one or more isoprene units, or a monoterpene or a sesquiterpene or a sesquiterpene or a diterpene group; R4 or R5 represent hydrogen or lower alkyl; R6 represents lower alkyl; and X represents F or Cl or Br or I.

    摘要: Biological applications of synthetic and natural alkaloids derived from the tunicate Eudistoma sp. are disclosed. A method regulating cell growth includes contacting one or more cells with an effective concentration of a compound for regulating cell growth. These compounds include: Segoline A, Segoline B, Isosegoline A, Norosegoline, Debromoshermilamine, Eilatin, 4-methylpyrido[2,3,4-kl]acridine, pyrido[2,3,4-kl]acridine, 1-acetyl-2,6-dimethylpyrido[2,3,4-kl]acridine, and derivatives and combinations of these compounds. An effective concentration range for using these compounds can range from approximately 0.1 .mu.M to 100 .mu.M. The effective concentration range for Eilatin, the most potent of these compounds is from 0.01 .mu.M to 0.99 .mu.M, and the effective concentration range for the other compounds of the present invention is from about 1.0 .mu.M to 100 .mu.M. The method has been shown to suppress growth of tumor cells, to induce differentiation of the tumor cells, and induce reverse transformation of the tumor cells. In transformed cells, the method induces reverse transformation. The method also inhibits the proliferation of cells. The examples show that the method of the present invention affects cyclic AMP mediated biological processes. At the effective concentrations this method affects the cyclic AMP mediated biological processes of cells to achieve the results described above.
