Oleamide

(9Z)-octadec-9-enamide

C18H35NO (281.2719)


Oleamide is an amide of the fatty acid oleic acid. It is an endogenous substance: it occurs naturally in the body of animals. It accumulates in the cerebrospinal fluid during sleep deprivation and induces sleep in animals. It is being studied as a potential medical treatment for mood and sleep disorders, and cannabinoid-regulated depression. The mechanism of action of oleamides sleep inducing effects is an area of current research. It is likely that oleamide interacts with multiple neurotransmitter systems. Oleamide is structurally related to the endogenous cannabinoid anandamide, and has the ability to bind to the CB1 receptor as a full agonist. Oleamide. CAS Common Chemistry. CAS, a division of the American Chemical Society, n.d. https://commonchemistry.cas.org/detail?cas_rn=301-02-0 (retrieved 2024-07-02) (CAS RN: 301-02-0).

Alverine

N-Ethyl-3-phenyl-N-(3-phenylpropyl)-1-propanamine

C20H27N (281.2143)


Alverine is a smooth muscle relaxant. Smooth muscle is a type of muscle that is not under voluntary control; it is the muscle present in places such as the gut and uterus. Alverine acts directly on the muscle in the gut, causing it to relax. This prevents the muscle spasms which occur in the gut in conditions such as irritable bowel syndrome and diverticular disease. It is used to relieve cramps or spasms of the stomach and intestines. It is also useful in treating irritable bowel syndrome (IBS) and similar conditions. It can also be used to help relieve period pain. Alverine is formulated as the citrate salt (5982-87-6).

petroselinate

cis-omega-12-octadecenoic acid

C18H33O2- (281.248)


Petroselinic acid, also known as (6z)-petroselinate or (Z)-6-octadecenoate, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Petroselinic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Petroselinic acid can be found in a number of food items such as jicama, common salsify, orange bell pepper, and cardoon, which makes petroselinic acid a potential biomarker for the consumption of these food products. Petroselinic acid can be found primarily in blood. Petroselinic acid is a fatty acid that occurs naturally in several animal and vegetable fats and oils. It is a white powder and is commercially available. In chemical terms, petroselinic acid is classified as a monounsaturated omega-12 fatty acid, abbreviated with a lipid number of 18:1 cis-6. It has the formula CH3(CH2)10CH=CH(CH2)4COOH. The term "petroselinic" means related to, or derived from, oil of Petroselinum, parsley. Petroselinic acid is an positional isomer of oleic acid .
