摘要:
This invention relates to an antibiotic NK86-0279 of the formula: which exhibits antifungal, antitumor, vascularizations-inhibitory and insecticidal activities, obtainable by culturing a microorganism of the genus Streptomyces, particularly Streptomyces bottropensis NK86-0279 (FERM BP-1787) and recovering the same from the culture medium. The invention also comprises a pure culture of this microorganism and mutants and variants thereof as well as pharmaceutical compositions comprising the new antibiotic.
摘要:
Novel antibiotics NK374186A, NK374186B, NK374186B3 and NK374186C3 having antibacterial, antineoplastic, immunomodulation, and liver regeneration promoting activities are provided. NK374186A, NK374186B, NK374186B3 and NK374186C3 are obtained by culturing NK374186 strain (FERM P-12285) (FERM-BP 3870) belonging to the genus Penicillium. NK374186A is a compound represented by a rational formula of C34H61N3O12S9 and having a molecular weight of M+ 735 (FD-MS m/z); NK374186B is a compound represented by a rational formula of C34H61N3O9 and having a molecular weight of M+ 655 (FD-MS m/z); NK374186B3 is a compound represented by a rational formula of C34H61N3O9 and having a molecular weight of M+ 655 (FD-MS m/z); and NK374186C3 is a compound represented by a rational formula of C32H59N3O7 and having a molecular weight of M+ 597 (FD-MS m/z).
