The synthesis of several sulfates of trichothecene mycotoxins is presented. Deoxynivalenol (DON) and its acetylated derivatives were synthesized from 3-acetyldeoxynivalenol (3ADON) and used as substrate for sulfation in order to reach a series of five different DON-based sulfates as well as T2-toxin-3-sulfate. These substances are suspected to be formed during phase-II metabolism in plants and humans
介绍了单端孢霉烯真菌毒素的几种硫酸盐的合成。脱氧雪腐镰刀菌烯醇 (DON) 及其乙酰化衍生物由 3-乙酰脱氧雪腐镰刀菌烯醇 (3ADON) 合成,并用作硫酸化的底物,以获得一系列五种不同的基于 DON 的硫酸盐以及 T2-toxin-3-sulfate。怀疑这些物质是在植物和人类的 II 期代谢过程中形成的。硫酸化使用硫酰基咪唑鎓盐进行,该盐在使用前合成。所有受保护的中间体和最终产品均通过 NMR 进行表征,并将作为参考材料用于真菌毒素毒理学和生物分析领域的进一步研究。

Multi-ring organic compounds that regulate gut motor activity, signal satiety, and reduce food intake in an individual are described Such compounds are useful to regulate food consumption and to treat conditions of excessive weight gam and obesity. These compounds are trichothecanes or trichothecenes of Formula I: wherein x is a single or double bond and R1 and R2 are, independently, selected from the group consisting of a branched or unbranched C1 to C6 alkyl group, a branched or unbranched C3 to C6 alkenyl group, a cyclic saturated C3-C6 ring, a monounsaturated C4-C6 ring, an optionally substituted aryl group, and a 5 or 6-membered heteroaromatic ring
