[Chemical Properties]

3-Methyl-1-cyclopentadecanone has a soft, sweet, tenacious, musky odor.
[Chemical Properties]

Colorless oily liquid
[Chemical Properties]

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.
[Chemical Properties]

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.
[Occurrence]

Reported found in natural musk
[Uses]

Muscone protects PC12 cells against glutamate-induced apoptosis.
[Preparation]

From condensation of dodecamethyl-ene-α,ω-dimethylketone hexadecane.

[Biological Activity]

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].
[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].
[storage]

Store at -20°C
