Compositions and methods of making and using thereof are provided with a specific antimicrobial activity and efficacy toward Gram-positive and Gram-negative bacteria and low levels of toxicity toward mammalian cells. The compositions include water-soluble molecules characterized by a hydrophobic interior fragment and side groups containing cationic groups. A class of these molecules is provided with variations in the length of the internal conjugated segment and in other molecular features, which impact the efficacy and toxicity. The substituents on the cationic functional group, the structural variations on the solubilizing group, and the length of the conjugated segment are important features affecting the antimicrobial property and the non-toxicity to mammalian cells of the composition.
Dehydrogenative Formation of Resorcinol Derivatives Using Pd/C–Ethylene Catalytic System
conversion of substituted 1,3-cyclohexanediones to the alkyl ethers of resorcinol using a Pd/C–ethylene system is reported. In these reactions, ethylene works as a hydrogen acceptor. The efficient synthesis of resveratrol was achieved using this protocol as a key step. In addition, the direct formation of substituted resorcinols was carried out by adding K2CO3 into the reaction media.
据报道,使用Pd / C-乙烯系统将取代的1,3-环己二酮转化为间苯二酚的烷基醚。在这些反应中,乙烯充当氢受体。使用该方案作为关键步骤,可实现白藜芦醇的有效合成。另外,通过向反应介质中加入K 2 CO 3来直接形成取代的间苯二酚。
