Abstract
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 C.sub.34 H.sub.61 N.sub.3 O.sub.12 S.sub.9 and having a molecular weight of M+ 735 (FD-MS m/z); NK374186B is a compound represented by a rational formula of C.sub.34 H.sub.61 N.sub.3 O.sub.9 and having a molecular weight of M+ 655 (FD-MS m/z); NK374186B3 is a compound represented by a rational formula of C.sub.34 H.sub.61 N.sub.3 O.sub.9 and having a molecular weight of M+ 655 (FD-MS m/z); and NK374186C3 is a compound represented by a rational formula of C.sub.32 H.sub.59 N.sub.3 O.sub.7 and having a molecular weight of M+ 597 (FD-MS m/z).
