Chemical and Biological Properties of S-1-Propenyl-l-Cysteine in Aged Garlic Extract.
S-1-Propenyl-l-cysteine (S1PC) is a stereoisomer of S-1-Propenyl-l-cysteine (SAC), an important sulfur-containing amino acid that plays a role for the beneficial pharmacological effects of aged garlic extract (AGE). The existence of S1PC in garlic preparations has been known since the 1960's. However, there was no report regarding the biological and/or pharmacological activity of S1PC until 201...
متن کاملExperimental and theoretical study of aqueous cis-pinonic acid photolysis.
Direct aqueous photolysis of cis-pinonic acid (PA; 2-(3-acetyl-2,2-dimethylcyclobutyl)acetic acid; CAS Registry No. 473-72-3) by 280-400 nm radiation was investigated. The photolysis resulted in Norrish type II isomerization of PA leading to 3-isopropenyl-6-oxoheptanoic acid (CAS Registry No. 4436-82-2), also known as limononic acid, as the major product, confirmed by (1)H and (13)C NMR analysi...
متن کاملThe Decomposition of Cysteine in Aqueous Solution*
In a recent study (1) it was shown that cystine could be decomposed by boiling distilled water with the formation of cysteine, hydrogen sulfide, and elementary sulfur. The decomposition of cysteine under similar conditions should aid in a clearer explanation of the mechanisms involved in the breakdown of these two amino acids. The action of alkaline reagents on cysteine and its derivatives has ...
