    • 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.
    • 合成和天然生物碱的生物应用来源于调味汁。 被披露。 调节细胞生长的方法包括使一种或多种细胞与有效浓度的化合物接触以调节细胞生长。 这些化合物包括:Segoline A,Segoline B,Isosegoline A,Norosegoline,脱氯西米明,Eilatin,4-甲基吡啶并[2,3,4-kl]吖啶,吡啶并[2,3,4-kl]吖啶,1-乙酰基-2 ,6-二甲基吡啶并[2,3,4-k]]吖啶,以及这些化合物的衍生物和组合。 使用这些化合物的有效浓度范围可以为约0.1μM至100μM。这些化合物中最有效的Eilatin的有效浓度范围为0.01μM至0.99μM,并且对于 本发明的其它化合物为约1.0μM至100μM。已经显示该方法抑制肿瘤细胞的生长,诱导肿瘤细胞的分化,并诱导肿瘤细胞的逆转化。 在转化细胞中,该方法诱导逆转化。 该方法还抑制细胞增殖。 实施例表明本发明的方法影响环AMP介导的生物过程。 在有效浓度下,该方法影响环AMP介导的细胞生物过程,以达到上述结果。
