• Product Overview:
  Viridicatumtoxin in a mycotoxin originally isolated from Penicillium that has diverse biological activities, including antimicrobial, cytotoxic, and toxic properties.{36724,30257,36725} It inhibits the growth of B. subtilis, M. luteus, C. perfringens, B. fragilis, and methicillin-resistant S. aureus (MRSA; MICs = 0.39-1.56 µg/ml), as well as C. albicans, S. cerevisiae, M. racemosus, A. niger, and P. chrysogenum (MICs = 6.2-25 µg/ml), but has no activity against M. smegmatis, E. coli, K. pneumoniae, P. aeruginosa, or S. marcescens (MICs = >100 µg/ml).{36725} Viridicatumtoxin inhibits the production of polyprenyl alcohols by S. aureus undecaprenyl pyrophosphate (UPP) synthase, E. coli octaprenyl pyrophosphate synthase (OPS), and S. cerevisiae dehydrodolichyl pyrophosphate (DedoIPP) synthase in vitro (IC50s = 3.1, 21, and 71 µM, respectively). It has cytotoxic effects against human Jurkat T (IC50 = 4.92 µM), chronic lymphocytic leukemia (CLL; LC50 = 0.7-3.5 nM), and bone marrow-derived HS-5 stromal cells.{30257,36725} Viridicatumtoxin is toxic to rats and mice when administered intraperitoneally (LD50s = 80 and 90 mg/kg, respectively) and to rats when administered via gastric intubation (LD50 = 122.4 mg/kg), but not to rats or mice when administered orally or through subcutaneous injection.{36724,36726}
