The present invention relates to improvements in or relating to Allium extracts. In particular, it relates to improvements in or relating to extending the therapeutic half- life or duration of Allium extracts. The invention also relates to the synthesis of certain thiosulfinate compounds, especially to the synthesis of methyl allyl thiosulfinate and allyl methyl thiosulfinate, in particular from either methiin or alliin alone or a mixture of both. The invention further relates to the synthesis of methyl allyl thiosulfinate, allyl methyl thiosulfinate, allicin, and 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. A high yielding, optimized synthesis of allicin starts from alliin, whereas methyl methyl thiosulfinate is advantageously obtained from methiin. Also provided is a kit comprising methiin in a first container and/or alliin in a second container and an allinase source, in particular garlic powder in a third container. Finally, the invention provides a method of preparing a mixture of methyl allyl thiosulfinate, allyl methyl thiosulfinate, allyl allyl thiosulfinate (allicin) and methyl methyl thiosulfinate from methiin and pieces of an Allium species.
本发明涉及改进或与Allium提取物相关的改进。具体而言,涉及延长Allium提取物的治疗半衰期或持续时间的改进。该发明还涉及某些硫代磺酸酯化合物的合成,特别是甲基烯丙基硫代磺酸酯和烯丙基甲基硫代磺酸酯的合成,特别是从单独的蒜素或葱素或两者的混合物中合成。该发明进一步涉及从单独的蒜素或葱素或两者的混合物中,在不同的摩尔或质量比下,合成甲基烯丙基硫代磺酸酯、烯丙基甲基硫代磺酸酯、大蒜素和甲基甲基硫代磺酸酯的混合物的合成,具体取决于反应条件。从蒜素开始的大蒜素高产量、优化合成,而甲基甲基硫代磺酸酯有利地从蒜素中获得。还提供了一个工具包,其中包括第一个容器中的蒜素和/或第二个容器中的葱素以及第三个容器中的大蒜粉作为蒜素酶源。最后,该发明提供了一种从蒜素和Allium物种的片段中制备甲基烯丙基硫代磺酸酯、烯丙基甲基硫代磺酸酯、烯丙基烯丙基硫代磺酸酯(大蒜素)和甲基甲基硫代磺酸酯的混合物的制备方法。
