Sicherheit & Vorschriften

Regulatorische Informationen	4,17-Dioxabicyclo14.1.0heptadecane-5,9-dione, 7,11-dihydroxy-8,8,10,12-tetramethyl-3-(1E)-1-methyl-2-(2-methyl-4-thiazolyl)ethenyl-, (1S,3S,7S,10R,11S,12S,16R)-: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.
Minimum Risk Level	Acute Oral: 0.01 mg/kg/day (L134)
Treatment	EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Gesundheitliche Auswirkungen	PBB exposure may cause weight loss, skin disorders (such as acne), nervous and immune systems effects, and effects on the liver, kidneys, and thyroid gland. (L628)
Expositionspfade	Oral (L628)inhalation (L628)dermal (L628)
Toxizitätsübersicht	The exact mechanism of toxicty of PBBs varies depending on the specific congener. The predominant interaction is believed to involve the aryl hydrocarbon receptor (AhR). PBBs bind to and activate the AhR, which in turn initiates the transcriptional upregulation of a number of genes, affecting biochemical and endocrine pathways, cell cycle regulation, morphogenesis, oxidative stress response, and various other processes. This results in the numerous toxic responses characteristic of PBBs. Some of the known induced genes include the cytochrome P-450-dependent monooxygenases CYP1A1 and CYP1A2. (L628)
Signs and Symptoms	Symptoms of PBB exposure may include nausea, abdominal pain, loss of appetite, joint pain, fatigue, and weakness. (L629)
Carcinogen Classification	2A, probably carcinogenic to humans. (L135)
Wassergefährdungsklasse (WGK)	3

Anwendungen & Verwendung

Verwenden

The epothilones are a novel class of antineoplastic agents possessing antitubulin activity. Epothilone A, B isolated from Sorangium cellulosum was associated with cell cycle arrest at G2/M transition and apoptosis that was resisted with overexpression of β-tubulin and P-glycoprotein in human bladder carcinoma cell.
