designed and synthesized in a one-pot reaction in 11-76% yields. All isothiocyanates thus generated were evaluated for the first time for antibacterial activity on Pseudomonas aeruginosa and Staphylococcus aureus bacterial strains, and had satisfactory antibacterial activity in most cases. The highest activity, similar to that of reference gentamicin activity against S. aureus, was seen in compounds
A series of phosphonates, phosphinates and phosphine oxides isothiocyanate-derived mercapturic acids were synthesized. A temperature dependence dynamic proton decoupled 31P NMR studies indicated that in most cases the compounds were obtained as a mixture of rotamers. Moreover, biologically relevant reversibility of mercapturic acidssynthesis from the parental isothiocyanates was confirmed. All compounds
合成了由异硫氰酸酯衍生的一系列膦酸酯,次膦酸酯和膦氧化物。温度依赖的动态质子去耦311 H NMR研究表明,在大多数情况下,这些化合物是以旋转异构体的混合物形式获得的。此外,证实了由亲本异硫氰酸酯合成的巯基酸的生物学相关的可逆性。在人结肠癌细胞系(LoVo及其耐阿霉素的亚系LoVo / DX)中,所有化合物均在体外被评估为高活性抗增殖剂。细胞周期进程和caspase-3活性分析表明,化合物具有中等程度的凋亡诱导剂活性,并且对LoVo细胞的细胞周期进程影响不大。我们的结果证实,异硫氰酸酯衍生的巯基酸为母体化合物提供了合理的替代品,并且可以在未来有关异硫氰酸酯作为抗癌剂的研究中取代它们。

Disclosed are novel rigidified compounds having a rhodanine-like residue and at least one aryl or heteroaryl residue linked to the rhodanine-like residue, whereby a core structure of these compounds, as defined in the specification, is characterized as having one or zero free-to-rotate bonds. Also disclosed are pharmaceutical compositions containing these rigidified compounds and uses thereof for modulating the activity of heparanase and hence in the treatment of heparanase-associated diseases and disorders, and uses thereof for modulating the activity of heparin-binding proteins and hence in the treatment of heparin-binding proteins-associated diseases and disorders as well as in the treatment of medical conditions that are at least partially treatable by rhodanine or a rhodanine analog.
