  Facile Amide Bond Formation from Carboxylic Acids and Isocyanates

  摘要：

  A wide variety of carboxylic acids in the form of their salts condense with aryl isocyanates at room temperature with loss of carbon dioxide to give the corresponding amides in high yield. Application of the reaction to acyl isocyanates gives unsymmetric imides. The reaction is compatible with hydroxyl groups and both Fmoc and Boc protecting groups for amines and is applicable to aliphatic, aromatic, and heteroaromatic acids.

  The invention relates to compounds, compositions and polymers comprising a first component adapted to promote germination of Clostridium difficile (C.diff) and a second component which acts as an antimicrobial agent. Said compounds, compositions and polymers are useful for destroying C.diff where conventional antimicrobial agents are unsuccessful. The compositions can be formulated as coating or materials which actively destroy C.diff which come into contact with it. The germination promotion is induced by bile salts. The invention also relates to the use of such materials as a treatment for C.diff associated diseases and toxic megacolon.

  这项发明涉及包含第一成分的化合物、组合物和聚合物，该第一成分适用于促进厌氧梭菌（C.diff）的萌发，并包含作为抗菌剂的第二成分。所述化合物、组合物和聚合物可用于在传统抗菌剂无效的情况下销毁C.diff。这些组合物可以制成涂层或材料的形式，主动破坏与其接触的C.diff。胆盐诱导促进萌发。该发明还涉及将这类材料用作治疗C.diff相关疾病和毒性巨结肠的用途。
