Carvone is a chiral organic compound with the molecular formula C10H14O. It is a colorless liquid that is found in the essential oils of several plants, most notably caraway seeds, dill seeds, and spearmint. The two enantiomers of carvone have distinct odors: (S)-carvone has a caraway-like odor, while (R)-carvone has a spearmint-like odor. Carvone is used as a flavoring agent in food and beverages, and it is also used in perfumes and cosmetics. Carvone is synthesized commercially by several methods, including the oxidation of limonene. Carvone has been shown to have a number of biological effects, including antibacterial, antifungal, and anti-inflammatory activities. It is also a potent inhibitor of the enzyme acetylcholinesterase, which is involved in the breakdown of acetylcholine, a neurotransmitter. Carvone is studied for its potential therapeutic applications, such as in the treatment of Alzheimer's disease and other neurodegenerative disorders. Carvone is also studied for its potential use as a pesticide and a food preservative. The distinct odors of the two enantiomers of carvone make it an interesting compound for studying the relationship between molecular structure and smell.'

Carvone is a monoterpene ketone contained in the essential oils of several aromatic and medicinal plants. Carvone (l-carvone) is a mint-tasting flavour additive that most of us is exposed to and can cause allergic contact reactions.
S-Carvone has been described as a negative regulator of mevalonic acid (MVA) production by interfering with 3-hydroxy-3-methyl glutaryl coenzyme A reductase (HMGR) activity. Carvone is occasionally reported as an allergen, usually in flavorings.

Brain infarction is the result of a cascade of events initiated by inadequate blood flow through the brain that is followed by HYPOXIA and HYPOGLYCEMIA in brain tissue.

| Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445) | 0 | 2.47 | 2 | 0 |
| Hyperpigmentation Excessive pigmentation of the skin, usually as a result of increased epidermal or dermal melanin pigmentation, hypermelanosis. Hyperpigmentation can be localized or generalized.

| Neuroblastoma A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome.
