In A549 cells, verrucarin J (0, 5, 10, 20, 50 nM; 24 hours) causes apoptosis [1]. The cell growth of A549 and H1793 cells was considerably decreased by verrucarin J (0, 1, 2, 5, 10, 20, 50 nM; 24, 48, 72 hours), with IC50 values of roughly 10 nM and 20 nM after 48 hours of treatment, respectively[1]. For HCT 116 and SW-620 cell growth, verrucarin J (0, 0.1, 0.2, 0.3, 0.4, 0.5 μM; 24 hours) had an IC50 of 300 nM [2]. Verrucarin J (0, 10, 20 nM, 48 hours) suppresses the expression of important CSC-specific genes (ALDH1, LGR5, OCT4, and CD133) in A549 cells and inhibits the Wnt1/β-catenin and Notch1 cancer stem cell (CSC) self-renewal pathway [1]. Compound 2, Verrucarin J, exhibits noteworthy efficacy against Candida albicans and Mucor michelia at 50 μg/disk [3]. Verrucarin J has a comparable impact against the arenavirus Tacaribe and decreases JUNV production by more than 2 log units [4]. Verrucarin J has a cytotoxic concentration 50% (CC50) of 8.2 ng/mL, which has the potential to decrease Vero cell viability [4].

In xenograft animals, intraperitoneal injection of Verrucarin J (0.5 mg/kg) for 4 weeks suppresses the growth of tumors generated by AKT [2]. Verrucarin J is an extremely potent anticancer medication that can stop tumor development and metastasis (0.1, 0.5, 2.0 mg/kg; intraperitoneally administered for three weeks) [5].

| Animal Protocol |
Animal/Disease Models: 6-8 week old BALB/c athymic nude mice (nu/nu)[2] with pCMV/HCT 116 and AKT/HCT 116 xenografts [2]
Doses: 0.5 mg/kg body weight Route of Administration: intraperitonealResults 4 weeks after injection: diminished expression of pro-survival markers pAKT, Notch1, p65 and Ki67 in all tumors. Animal/Disease Models: Female naked nu/nu (5 to 6 weeks old) mice with A2780 xenografts [5] Doses: 0.1, 0.5, 2.0 mg/kg (Vehicle: 10% DMSO, 90% Tricaprylin Ester) Route of Administration: intraperitoneal (ip) injection three weeks. Results 10 days after injection of A2780 cells: tumor weight reduction (32% compared to control) and reduction in visible metastases at a dose of 0.1 mg/kg. At the dose of 0.5 mg/kg, a significant reduction in peritoneal tumors was seen (61% reduction compared to the control group), and a significant reduction in metastasis was seen. Ovarian tumor weight at 0.5 mg/kg was diminished by 71% compared to vehicle. At a lethal dose of 2 mg/kg, mice developed abdominal swelling, fluid swelling, and subseque |

Metabolism / Metabolites
Trichothecene toxins are lipophilic, thus readily absorbed through the skin, intestines, and lung mucosa. They are primarily metabolized in the liver by cytochrome P-450 and trichothecene-specific carboxylesterases, although some metabolic activity is also observed in other tissues such as the kidneys, spleen, and intestines. Trichothecene toxins are metabolized into less toxic metabolites through reactions such as hydrolysis, hydroxylation, deepoxidation, and glucuronidation. These metabolites are excreted in urine and feces. (L1910, L1949) |
| Toxicity/Toxicokinetics |
Toxicity Summary
Unlike many other fungal toxins, trichothecene toxins exert their biological activity without metabolic activation, instead reacting directly with cellular components. Trichothecene toxins are cytotoxic to most eukaryotic cells because they potently inhibit protein synthesis. They achieve this by freely crossing the plasma membrane and binding with a high affinity to ribosomes. Specifically, they interfere with the peptidyl transferase active site located at the 3' end of the 28S ribosomal RNA, inhibiting the initiation, elongation, or termination steps of protein synthesis and leading to polyribosome depolymerization. Protein synthesis is a fundamental function of all tissues, but tissues with active, rapidly growing, and dividing cells are particularly sensitive to these toxins. Furthermore, binding to ribosomes is thought to activate proteins in downstream signaling pathways associated with immune responses and apoptosis, such as mitogen-activated protein kinase. This is known as ribosomal toxicity stress. Trichothecene toxins may also induce changes in membrane structure, leading to increased lipid peroxidation and inhibition of mitochondrial electron transport activity. They can further induce apoptosis by generating reactive oxygen species. Other secondary effects of trichothecene toxins include inhibition of RNA and DNA synthesis and inhibition of mitosis.

| Additional Infomation |
Trichosporin J is a trichothecene toxin. Trichothecenes are a class of chemically related fungal toxins produced by various fungi in the genera Fusarium, Myrothecium, Trichoderma, Cephalosporium, Verticimonosporium, and Stachybotrys. The most important structural features for the biological activity of trichothecenes include: a 12,13-epoxy ring, a hydroxyl or acetyl group at an appropriate position on the trichothecene core, and the structure and position of the side chains. They are produced by various Fusarium fungi, such as F. graminearum, F. sporotrichioides, F. poae, and F. equiseti, which are found on various grains such as wheat, oats, and corn. Some molds that produce trichothecene toxins, such as Stachybotrys chartarum, can grow in humid indoor environments and may cause health problems for building occupants. (L1948)
