campaigns, we decided to perform a systematic study on their promiscuity. An amount of 163 rhodanines, hydantoins, thiohydantoins, and thiazolidinediones were synthesized and tested against several targets. The compounds were also characterized with respect to aggregation and electrophilic reactivity, and the binding modes of rhodanines and relatedcompounds in published X-ray cocrystal structures were analyzed
2-Thiohydantoin derivatives are produced by heating a mixture of thiourea and an α-amino acid. The method described offers the advantages of simplicity, low cost, easy work-up and scalability.

report the investigation of hydantoins and thiohydantoins derived from L and d-amino acids as inhibitors against the Canavalia ensiformis urease (CEU). The biochemical in vitro assay against CEU revealed a promising inhibitory potential for most thiohydantoins with six of them showing %I higher than the reference inhibitor thiourea (56.5%). In addition, thiohydantoin derived from l-valine, 1b, as well as
我们报告了从L和d氨基酸中提取的乙内酰脲和硫代乙内酰脲作为抗Canavalia ensiformis脲酶 (CEU) 抑制剂的研究。针对 CEU的体外生化试验显示,大多数硫代乙内酰脲具有良好的抑制潜力,其中 6 种显示 %I 高于参考抑制剂硫脲 (56.5%)。此外,衍生自l-缬氨酸的硫代乙内酰脲1b以及衍生自l的乙内酰脲2d-甲硫氨酸被确定为最有效的抑制剂,%I 分别为 90.5 和 85.9。酶动力学研究证明了这些化合物的混合和非竞争性抑制曲线,1b的 K i值为 0.42 mM , 2d的 K i 值为0.99 mM 。这些从传统比色法获得的动力学参数与 K D严格相关通过脲酶复合物的饱和转移差 (STD) 技术光谱测量的值。STD 也用于证明负责与酶结合的配体部分。分子对接研究表明,硫代乙内酰脲和乙内酰脲环可以作为药效团,因为它们通过氢键相互作用与酶活性和/或变构位点中的关键氨基酸

Synthesis and Herbicidal Activity of 5-(4-Hydroxybenzyl)-2-Thioxoimidazolidin-4-one Esters
A series of novel 5-(4-hydroxybenzyl)-2-thioxoimidazolidin-4-one esters were synthesized under mild conditions by the reaction of 5-(4-hydroxybenzyl)-2-thioxoimidazolidin-4-one and carboxylic acids with DCC and DMAP as the promoters. Their structures were confirmed by 1H-NMR, IR, ESI-MS and elemental analysis. The preliminary bioassy results indicated that some of compounds exhibit good herbicidal activity against Zea mays, Triticum aestivum and Arabidopsis thaliana. The further greenhouse test showed that compounds 6-16 and 6-28 have 60%, 50% and 50% efficacy against Stellaria media, Echinochloa crus-galli and Setaria viridis at 1,000 g/ha, respectively.
