  Bromophenols as Candida albicans isocitrate lyase inhibitors

  摘要：

  A new series of bromophenols was synthesized by reactions of corresponding phenol analogs with bromine. The synthesized compounds were tested for inhibitory activity against isocitrate lyase (ICL) of Candida albicans and antimicrobial activity against Gram-positive and, Gram-negative bacteria and fungi. Among the synthesized bromophenols, bis(3-bromo-4,5-dihydroxyphenyl)methanone (11) and (3-bromo-4,5-dihydroxyphenyl)(2,3-dibromo-4,5-dihydroxyphenyl)methanone (12) displayed potent inhibitory activities against ICL, showing a stronger inhibitory effects than were found with natural bromophenol 1. The preliminary structure-activity relationships were investigated in order to determine the essential structural requirements for the inhibitory activities of these compounds against ICL of C. albicans.

  Provided are a multi-block copolymer, a pressure-sensitive adhesive composition, a method of preparing a multi-block copolymer, a pressure-sensitive adhesive polarizing plate, and a liquid crystal display device. The pressure-sensitive adhesive composition including the multi-block copolymer may have excellent durability regardless of a temperature and/or humidity. In addition, the method of preparing a multi-block copolymer may prepare a multi-block copolymer increased in molecular weight which is structurally controlled with a simple process using a compound containing at least two halogen atoms. Accordingly, when included in a pressure-sensitive adhesive resin, the multi-block copolymer may have excellent cohesive strength in the resin, and a network structure during curing, and thus, when applied to a pressure-sensitive adhesive composition, the multi-block copolymer may be usefully applied to an optical member due to excellent durability regardless of a temperature and humidity.

  本文提供了一种多嵌段共聚物、一种压敏胶组合物、一种制备多嵌段共聚物的方法、一种压敏胶偏光板和一种液晶显示设备。包括多嵌段共聚物在内的压敏胶组合物不受温度和/或湿度的影响，可具有极佳的耐久性。此外，多嵌段共聚物的制备方法可制备出分子量增大的多嵌段共聚物，该共聚物可通过使用至少含有两个卤素原子的化合物的简单工艺进行结构控制。因此，当将多嵌段共聚物加入压敏型粘合剂树脂中时，该共聚物在树脂中可能具有优异的内聚强度，并在固化过程中具有网络结构，因此，当应用于压敏型粘合剂组合物时，该多嵌段共聚物由于具有优异的耐久性，无论温度和湿度如何，都可以有效地应用于光学部件。
