8-Deazafolic acid is a potent folate-dependent bacteria inhibitor, Streptococcus faecium (ATCC 8043) and Lactobacillus casei (ATCC 7469), and to have activity against lymphoid leukemia L1210 in mice.
Spirolaxine, a natural product isolated from Sporotrichum laxum ATCC 15155, has shown a variety of biological activities including promising anti-Helicobacter pylori property.
Dactylocyclines are novel tetracycline derivatives produced by Dactylosporangium SP. The fermentation of Dactylosporangium sp. (ATCC 53693) produced a mixture of tetracycline derivatives, from which several related tetracycline glycosides, known as rings,
Myceliothermophin E is a polyketide-amino acid hybrid fungal metabolite that has been found inT. thermophilusand has anticancer and antimicrobial activities.1,2It is cytotoxic to DLD-1, Hep3B, HepG2, and HGC-27 cancer cells (IC50s = 0.32, 0.42, 0.26, and 0.08 μg/ml, respectively).1Myceliothermophin E is active against methicillin-resistant, but not -sensitive,S. aureus(MICs = 15.8 and >100 μM, respectively).2 1.Gao, Y.-L., Zhang, M.-L., Wang, X., et al.Isolation and characterization of a new cytotoxic polyketide-amino acid hybrid from Thermothelomyces thermophilus ATCC 42464Nat.
