Tirilazad mesylate (U 74006F) is a non-glucocorticoid, lipid peroxidation inhibitor with antiviral and neuroprotective activities. It confines intracellular intramembranous foci, attenuates spinal cord injuries induced by trauma, stroke, and ischemia/reperfusion injuries, inhibits toxins in dogs, and is used in the study of neurological disorders.

Silibinin (Silybin) is the major active constituent of silymarin, a standardized extract of the milk thistle seeds, containing a mixture of flavonolignans consisting of silibinin, isosilibinin, silicristin, silidianin and others. Silibinin itself is a mixture of two diastereomers, silybin A and silybin B, in approximately equimolar ratio. Both in vitro and animal research suggest that silibinin has hepatoprotective (antihepatotoxic) properties that protect liver cells against toxins. Silibinin has also demonstrated in vitro anti-cancer effects against human prostate adenocarcinoma cells, estrogen-dependent and -independent human breast carcinoma cells, human ectocervical carcinoma cells, human colon cancer cells, and both small and nonsmall human lung carcinoma cells.

Anti-MRSA agent 20 (Compound a4) is an antimicrobial agent targeting MRSA with a minimum inhibitory concentration (MIC) of less than 0.03125 μg mL. It binds to the peptidyl transferase center of the ribosome, inhibiting the synthesis of MRSA toxins and bacterial division, thereby suppressing bacterial survival. Furthermore, Anti-MRSA agent 20 significantly reduces the pulmonary MRSA load and diminishes lung damage in mice infected with MRSA (ED50= 6.48 mg kg).

Tubulysin Aintermediate-1 is an intermediate in the synthesis of the cytotoxic peptide Tubulysin A. Tubulysin A (TubA) acts as an antibiotic (antibiotic), anti-microtubule toxins (anti-microtubule toxins), and apoptosis (apoptosis) inducer, which can be isolated from myxobacteria. It exhibits anti-angiogenic, anti-microtubule, anti-mitotic, and anti-proliferative properties, effectively blocking cells in the G2/M phase, inhibiting tubulin polymerization, and inducing depolymerization of isolated microtubules. Tubulysin A serves as an ADC Cytotoxin (ADC Cytotoxin) in the synthesis of ADCs.

Lolitrem B is one of many toxins produced by a fungus called Epichloë festucae (var. lolii), which grows in perennial ryegrass. The fungus is symbiotic with the ryegrass; it doesn't harm the plant, and the toxins it produces kill insects that feed on ryeg

Pumiliotoxins (PTXs), are one of several toxins found in the skin of poison dart frogs. There are three different types of this toxin: A, B and C, of which toxins A and B are more toxic than C. Pumiliotoxins interfere with muscle contraction by affecting

Emestrin, a mycotoxin originally isolated from *E. striata*, exhibits antimicrobial, immunomodulatory, and cytotoxic activities. It is effective against fungi *C. albicans* and *C. neoformans*, and bacteria *E. coli*, *S. aureus*, and methicillin-resistant *S. aureus* (MRSA; IC50s = 3.94, 0.6, 2.21, 4.55, and 2.21 μg ml, respectively). Emestrin acts as a chemokine (C-C motif) receptor 2 (CCR2) antagonist (IC50 = 5.4 μM in a radioligand binding assay using isolated human monocytes). At 0.1 μg ml, it induces apoptosis in HL-60 cells and causes necrosis in heart, thymus, and liver tissues in mice at doses of 18-30 mg kg.

Janthitrem A is a mycotoxin that has been found inP. janthinellum.1It induces tremors in mice and decreases the time to fall from the rotarod when administered at a dose of 4 mg/kg.2Janthitrem A (20 μg/g) also reducesW. cervinatalarvae weight gain and food consumption. 1.Gallagher, R.T., Latch, G.C., and Keogh, R.G.The janthitrems: Fluorescent tremorgenic toxins produced by Penicillium janthinellum isolates from ryegrass pasturesAppl.

Globotriaosycleramides are glycosphingolipids found in mammalian cell membranes that are synthesized from lactosylceramides . They act as receptors for Shiga and Shiga-like toxins in vitro and in vivo. Globotriaosylceramides accumulate in endothelial cells, pericytes, vascular smooth muscle cells, renal epithelial cells, dorsal ganglia neuronal cells, and myocardial cells in patients with Fabry disease, a lysosomal storage disorder characterized by a deficiency in the enzyme α-galactosidase A. Globotriaosylceramides act as natural resistance factors to HIV infection, interacting with HIV gp120 to prevent its interaction with chemokine co-receptors and subsequent fusion of HIV to host cell membranes. This product contains a mixture of hydroxy fatty acid-containing globotriaosylceramides isolated from porcine red blood cells (RBCs).

Globotetraosylceramides are bioactive neutral glycosphingolipids. They are the major glycolipids in human erythrocytes. They act as receptors for the Shiga toxins Stx1, Stx2, and Stx2e, the cytotoxic protein pierisin-1, and parvovirus B19. Globotetraosylceramides increase the expression of proteins responsible for enamel deposition, including ameloblastin, amelogenin, and enamelin, in dental epithelial cells and activate the ERK and p38 MAPK signaling pathways. Levels of globotetraosylceramides are elevated in fibroblasts from patients with salt and pepper syndrome, a neurocutaneous condition characterized by intellectual disability and hyper- and hypo-pigmented skin. Globotetraosylceramides (porcine RBC) contains a mixture of globotetraosylceramides with variable fatty acyl chain lengths isolated from porcine red blood cells.
