Usage

Description

(R)-Prunasin is a cyanogenic glucoside that is the precursor to amygdalin, a bitter component found in species of the genera Prunus and Olinia. It can be degraded to hydrogen cyanide, glucose, and benzaldehyde by the action of prunasin hydrolase and mandelonitrile lyase and possesses inhibitory effects on plant growth. (R)-Prunasin reportedly inhibits rat DNA polymerase β, which performs base excision repair required for DNA maintenance and replication, with an IC50 value of 98 μM.

Chemical Properties

White Solid

Uses

Used in the synthesis of cyanogen glycoside. A component of antiperspirants, deodorants, body soaps, shampoos, hair rinses, and hair

Enzyme inhibitor

This cyanogenic glucoside (FW = 295.29 g/mol; CAS 99-18-3), also known as D(R)-mandelonitrile-b-D-glucoside, is readily obtained from amygdalin and is found in the pits of Prunus serotina. Prunasin is soluble in water and will give rise to prulaurasin (i.e., the diastereoisomeric mixture of DL(RS)- mandelonitrile-b-D-glucoside [i.e., prunasin and sambunigrin]). Target(s): DNA-directed DNA polymerase; DNA polymerase b; and a,a trehalase.

Maesil (Prunus mume, green plum)-based products have been widely used in Asian cooking, which may contain amygdalin enzymatically converted to hydrogen cyanide after oral ingestion. In this study, the toxicity of Maesil syrups matured with and without Mae

Synthesis and Biological Evaluation of Cyanogenic Glycosides

An efficient procedure for the synthesis of cyanogenic glycosides with different carbohydrate units was developed. Amygdalin (3), prunasin (1), sambunigrin (2), and neoamygdalin (21) were prepared according to the elaborated method, and biological tests, including antifungal, antibacterial, and cytotoxic activities, were performed.
