标题:穿心莲内酯c-14芳基氨基甲酸酯衍生物的设计,合成及抗癌评价
摘要:在这项研究中,我们探索了一种简洁,温和的合成路线来生产穿心莲内酯的新型 C-14 芳基氨基甲酸酯衍生物,穿心莲内酯是一种已知的抗炎和抗癌天然产物.在评估其对胰腺导管腺癌(Pdac) 细胞的抗癌功效后,一些衍生物对 Panc-1 细胞表现出比穿心莲内酯更强的细胞毒性.此外,我们证明了一种衍生物,化合物3M,可有效降低 Pdac 系 Panc-1 和 Mia Paca-2 中致癌 P53 突变蛋白(p53 R273H和 P53 R248W )的表达,增殖和迁移.因此,该新型衍生物有望作为抗胰腺癌的抗癌剂.总之,我们的研究拓宽了穿心莲内酯的衍生物库,并开发了一种具有非常好抗 Pdac 抗癌活性的穿心莲内酯芳基氨基甲酸酯衍生物.

标题 :Synthesis of linear polyoxazolidinones using uretdiones as diisocyanate component
发明人：QUELL AGGELIKI; THOMAS HANS-JOSEF; ELING BEREND
权利人:BASF SE
摘要:A process for preparing a thermoplastic polymer involves reacting at least components (a) to (b), in the presence of a catalyst composition (c). Component (a) is an isocyanate composition containing at least one uretdione diisocyanate (a-i), and component (b) is an epoxide composition containing at least one diepoxide (b-i). The catalyst composition (c) contains at least one ionic liquid (c-i), preferably selected from 1-ethyl-3-methyl imidazolium bromide, 1-benzyl-3-methyl imidazolium chloride. 1-butyl-1-methylpiperidinium chloride, 1-ethyl-2,3-dimethylimidazolium bromide, 1-(2-hydroxyethyl)-3-methyl imidazolium chloride, butyl-1-methylpiperidinium acetate, or mixtures of two or more thereof. A thermoplastic polymer obtained or obtainable from the process is useful for the preparation of a fibre or a molded article or as a modifier for another thermoplastic material.
