摘要:Improvements in or relating to Allium extracts. In particular, improvements in or relating to extending the therapeutic half-life or duration of Allium extracts. The invention further relates to the synthesis of methyl methyl thiosulfinate in a mixture with varying molar or mass ratios depending on the reaction conditions, in particular from either methiin or alliin alone or a mixture of both. Methods of treatment methicillin-resistant Staphylococcus aureus are also provided. Also provided is a kit comprising methiin in a first container and alliin in a second container.

摘要:New lactone intermediates useful in the synthesis of peptides are prepared by reacting an α-amino acid with an active carbonyl compound which forms a Schiff's base. The latter is treated with a condensing agent so that cyclization occurs and a lactone is formed from which a peptide may be produced by reaction with an amino acid ester and removal of the protecting groups.
