Abstract

The present invention relates to indole carbazole alkaloid and its preparation process and use. The present invention adopts Actinomadura sp.007 from ocean in fermentation to prepare indole carbazole alkaloid compound with novel chemical structure. Test shows that the indole carbazole alkaloid compound may be used as cell period inhibitor, tumor cell proliferation inhibitor and antitumor preparation.

Description

Technical field: [0001] The present invention relates to a novel indolecarbazole alkaloid compound, a method for preparing the indolecarbazole alkaloid compound by fermenting Actinomyces madurasp. agents, tumor cell proliferation inhibitors or antineoplastic agents. Background technique: [0002] Indolecarbazole alkaloid staurosporine (staurosporine) is isolated from Streptomyces AM-2282 product (S.Omura, Y.Iwai, A.Nalagawa, et al., J.Antibiot., 1977,30 , 275; A.Furusaki, N.Hashiba, T.Matsumoto, et al., J.Chem.Soc.Chem.Comm., 1978, 800-801) have been found to have a variety of important biological activities, such as antibacterial, Dilation of blood vessels, cytotoxic activity, inhibition of platelet aggregation and inhibition of protein kinase C, etc. Since staurosporine aglycon is of great significance to its related biological activities (D. Meksurriyen, G.A. Cordell, J. Nat. Prod. 1988, 51, 884-892), staurosporine aglycon is used as the parent Indolecarbazole alkaloid...
