  Potential salicylamide antiplaque agents: in vitro antibacterial activity against Actinomyces viscosus

  摘要：

  A series of 55 salicylamides, including 3,5-dibromo-, 5-n-alkyl-, and 5-n-acylsalicyloyl derivatives of various anilines, heterocyclic amines, benzylamines, and alkylamines, was synthesized and evaluated for in vitro antibacterial activity against Actinomyces viscosus, an adherent oral microorganism implicated in periodontal disease. The in vitro minimum inhibitory concentrations of 15 4'-bromosalicylanilides were found to correlate (r = 0.92) with estimated log D values. Several nonhalogenated salicylanilides, such as 5-n-hexyl- (40) and 5-n-decanoyl-4'-nitrosalicylanilide (47), were found to exhibit higher levels of in vitro antibacterial activity against a number of Actinomycetes than did tribromsalan (1) or fluorophene (2).

  [Problem] To provide a method of producing an aromatic amino compound by using a primary or secondary amine compound and a halogenated aromatic compound as starting materials, and relying upon the Ullmann reaction, the method being capable of obtaining the highly pure aromatic amino compound in high yields and inexpensively. [Means for Solution] A method of producing an aromatic amino compound by using a primary or secondary amine compound having an aromatic ring group and a halogenated aromatic compound as starting materials, reacting the amine compound with the halogenated aromatic compound in the presence of a copper catalyst and a base so as to produce the aromatic amino compound having a structure in which an aromatic ring group derived from the halogenated aromatic compound is coupled to the amino group of the amine compound, wherein the amine compound and the halogenated aromatic compound are reacted together under a condition where an aromatic oxycarboxylic acid having a hydroxyl group and a hydroxycarbonyl group that are bonded to neighboring carbon atoms, is made present together with the copper catalyst and the base.

  The invention describes a composition for use in disinfecting a surface for personal use, such as a public restroom facility or telephone. The composition and delivery of the composition provides for the placement of a thin layer of disinfectant which includes a acid-base indicator. The acid-base indicator disappears as the thin layer effects the germicidal activity of the disinfectant. The composition is also rapidly drying, so that the acid-base indicator disappears as well as the disinfecting composition leaving the surface dry. The invention also relates to use of the compositions in a lotion, such as a sunscreen. Use of the acid-base indicator provides a method to visualize where the lotion is applied by color, with the color then later dissipating.

  本发明描述了一种用于消毒个人使用表面的组合物，例如公共洗手间或电话。该组合物及其输送方式提供了一层薄薄的消毒剂，其中包括酸碱指示剂。随着薄层发挥消毒剂的杀菌活性，酸碱指示剂消失。该组合物也具有快速干燥的特性，因此酸碱指示剂以及消毒剂在表面干燥后也会消失。本发明还涉及将该组合物用于洗涤剂，例如防晒霜。使用酸碱指示剂提供了一种通过颜色可视化涂抹洗涤剂的方法，颜色随后会消失。
