    摘要:
    硫氧还蛋白系统在癌细胞中起重要作用。抑制硫氧还蛋白还原酶(TrxR)已经成为选择性靶向癌细胞的有效策略。Withangulatin A(WA)是从酸浆(Solanaceae)整个草药中提取的天然产物,具有强大的抗癌活性和其他多种药理活性。为了提高活性和针对性,我们设计并制备了WA的41种半合成类似物。生物学评估表明,最有前途的化合物13a对HT-29细胞(人结肠癌细胞)显示出最显着的作用(IC 50= 0.08μM)。构效关系研究表明,α,β-不饱和酮和酯是必需基团,使13a与硫醇和硒醇进行迈克尔加成反应。液相色谱-质谱(LC-MS)分析证实,TrxR氧化还原中心的13a修饰的硒代半胱氨酸498(U)残基导致酶抑制。因此,化合物13a充当新型TrxR抑制剂,可能是有希望的癌症干预候选药物。

  • Latently-curable organosilicone release coating composition
    申请人:MINNESOTA MINING AND MANUFACTURING COMPANY
    公开号:EP0140530A1
    公开(公告)日:1985-05-08
    A latently-curable, organosilicone composition comprises a metal catalyzed organosilicone composition capable of undergoing hydrosilation and, as hydrosilation inhibitor, an organic monohydrogen derivative of an unsaturated aliphatic 1,4-dicarboxylic acid, i.e., maleic acid or acetylene dicarboxylic acid. The organic monohydrogen derivatives of use in this invention effectively inhibit catalyzed hydrosilation reactions at low or room temperature while allowing efficient hydrosilation reaction rates to occur at elevated temperatures. These monohydrogen derivatives perform their inhibitive function effectively at low concentration. The latently curable composition may be coated on a substrate to provide a release surface for an adjacent adhesive layer.
