  Design and Synthesis of 4,5-Disubstituted-thiophene-2-amidines as Potent Urokinase Inhibitors

  摘要：

  A study of the S1 binding of lead 5-methylthiothiophene amidine 3, an inhibitor of urokinase-type plasminogen activator, was undertaken by the introduction of a variety of substituents at the thiophene 5-position. The 5-alkyl substituted and unsubstituted thiophenes were prepared using organolithium chemistry. Heteroatom substituents were introduced at the 5-position using a novel displacement reaction of 5-methylsulfonylthiophenes and the corresponding oxygen or sulfur anions. Small alkyl group substitution at the 5-position provided inhibitors equipotent with 3 but possessing improved solubility. (C) 2002 Elsevier Science Ltd. All rights reserved.

  This application relates to thiophene azo dyes for use as hueing agents, laundry care compositions comprising such thiophene azo dyes, processes for making such thiophene azo dyes, and laundry care compositions and methods of using the same. The thiophene azo dyes contain a formally charged moiety and are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. These thiophene azo dyes are advantageous in providing a hueing effect, for example, a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics. The thiophene azo dyes are also generally stable to bleaching agents used in laundry care compositions.

  本申请涉及用作着色剂的噻吩偶氮染料、含有此类噻吩偶氮染料的衣物护理组合物、制造此类噻吩偶氮染料的工艺以及衣物护理组合物和使用方法。噻吩偶氮染料含有正式带电分子，通常由至少两种成分组成：至少一种发色团成分和至少一种聚合物成分。合适的发色团成分在紫外线照射下一般会发出蓝色、红色、紫色或紫罗兰色的荧光，也可以吸收光来反射这些相同的色调。这些噻吩偶氮染料在提供色调效果（例如，织物的增白效果）方面具有优势，同时不会随着时间的推移而积累，导致处理过的织物出现不希望看到的蓝色褪色。噻吩偶氮染料对洗衣护理组合物中使用的漂白剂通常也很稳定。
