Muscone Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften
3-Methyl-1-cyclopentadecanone has a soft, sweet, tenacious, musky odor.
Chemische Eigenschaften
Musk is secreted exclusively by the male animals of Moschus moschiferus, a wild deer living in themountains of Nepal,Tibet, and Mongolia.Thelight yellow secretion with a salve consistency accumulates in the abdominal pouch and probably serves to attract the females. When the pouch is dried, the secretion solidifies to form a brittle, brown mass with a characteristic odor. Since several Moschus species occur, large variations exist in the quality and specifications of musk. Hunting of the animals has been prohibited; therefore, only small quantities ofmusk are occasionally offered at extremely high prices. In the United States and Europe, naturalmusk is no longer used as a fragrance ingredient.
Chemische Eigenschaften
Colorless oily liquid
Chemische Eigenschaften
Muscone is an odoriferous constituent of natural musk. It is a colorless liquid with very soft, sweet, musky odor and a perfumery, animal tonality.Numerous syntheses have been developed for its preparation including enantioselective methods to obtain the naturally occurring (3R)-enantiomer (l-muscone,. Because of its excellent stability, it can be used in awide range of products to give elegant,warm, animal notes. It is important for the reconstitution of naturalmusk.
Occurrence
Reported found in natural musk
Verwenden
Muscone protects PC12 cells against glutamate-induced apoptosis.
synthetische
From condensation of dodecamethyl-ene-α,ω-dimethylketone hexadecane.

Biologische Aktivität
muscone is a potent anti-inflammatory agent, which has been implicated in reducing proinflammatory cytokines and end-plate degeneration [1]. muscone is a territorial releaser pheromone in moschus moschiferus. muscone is not produced by humans. muscone is animal pheromone with no effects on humans comparable to those of androstadienone [2]. (±)-muscone is an odoriferous constituent of musk, a glandular secretion originally collected from the male musk deer [3].
Sicherheitsprofil
Low oral and skin contact toxicity. A skin irritant. A flammable liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
in vitro
muscone reversed il-1β-induced upregulation of il-1β, tumor necrosis factor α, cyclooxygenase 2, inducible nitric oxide synthase, matrix metalloproteinase 13, aggrecanase 2, and nitric oxide and downregulation of col2α1 and aggrecan. in end-plate cartilage cultures, pretreatment with muscone (6.25, 12.5, 25 μmol/l) inhibited the il-1β-induced phosphorylation of extracellular signal-regulated kinases 1/2 and c-jun n-terminal kinase in a dose-dependent manner [1].
in vivo
in a rat model with induced intervertebral disc degeneration, muscone inhibited the expression of prostaglandin e2, 6-keto-prostaglandin f1α, il-1β, and tumor necrosis factor α and recovered the structural distortion of the degenerative disc [1].
