D-амигдалин химические свойства, назначение, производство
Описание
Amygdalin is a cyanogenic glycoside that has been found in seeds from plants of the Rosaceae family and has diverse biological activities. It induces cell cycle arrest at the G0/G1 phase, decreases cyclin A and Cdk2 levels, and inhibits cell growth in UMUC-3, RT112, and TCCSUP bladder cancer cells when used at concentrations ranging from 1.25 to 10 mg/ml. Amygdalin (3 mg/kg) reduces the number of primary microtubules and microvessels in aortic rings isolated from rats with diabetes induced by streptozotocin . In vivo, amygdalin reduces triglyceride, total cholesterol, and LDL levels and aortic sinus plaque area in an LDLR-/- mouse model of atherosclerosis. It also reduces production of TNF-α, IL-1β, and IL-6, as well as neutrophil and macrophage infiltration, in bronchoalveolar lavage fluid (BALF) in a mouse model of LPS-induced acute lung injury.

Использование
Amygdalin, a cyanide containing glycoside, may be used as a substrate to identify, differentiate and characterize enzymes such as maltase(s), emulsin(s) and β-glucosidase(s).
Определение
ChEBI: An amygdalin in which the stereocentre on the cyanohydrin function has R-configuration.

Laetrile, which consists mainly of amydgalin, a glycoside
extracted from the kernels of apricots, peaches and other fruits, has been available
for over 30 years in preparations purporting to be beneficial in the treatment of
cancer. Although there is no evidence that these are efficacious, preparations
continued to be widely used and, until the late 1970s, they were considered to be
harmless. However, oral dosage forms, which may be broken down in the gut to
hydrogen cyanide, have subsequently been shown to be potentially lethal. This has
resulted in restrictive regulatory measures in several countries.
