  3-amidocoumarins的合成，抗菌和几丁质酶抑制活性。

  摘要：

  已经合成了一系列3-amidocoumarins，并在体外测试了它们的抗微生物和几丁质酶抑制活性。其中，化合物5k，5l，8b-8d，8f和8g对某些测试菌株表现出良好的抗菌活性，MIC值在6.25-25 µg / mL范围内，而化合物5l，8b，8c和8f显示出良好的活性对抗至少一种或两种真菌菌株。某些被测化合物5d，5k，5l，8b和8c显示出显着的几丁质酶抑制活性，IC50值在3.74-5.6 µM范围内。其中5l被证明是有效的几丁质酶抑制剂，IC50值为3.74 µM。为了更好地理解酶-抑制剂的相互作用，所有合成化合物的分子对接研究均在烟曲霉几丁质酶1W9U上进行。化合物5l显示出与受体的高结合亲和力，结合能值为-8.44 Kcal / mol。该研究还提供了合成化合物的结构活性关系（SAR）。

  been developed for the synthesis of esters and amides. A wide range of carboxylic acids and alcohols or amines worked well under the developed reaction conditions, thus providing good to excellent (61–98%) yields of the corresponding esters and amides. The method worked well with bioactive substrates such as cholesterol, levulinic acid, and linoleic acid. Wide substrate scope, operational simplicity

  已经开发了一种新的 KPF 6促进的绿色方法来合成酯和酰胺。广泛的羧酸和醇或胺在开发的反应条件下工作良好，因此提供了良好至优异（61-98%）的相应酯和酰胺产率。该方法适用于胆固醇、乙酰丙酸和亚油酸等生物活性底物。广泛的底物范围、操作简单性、可扩展性和可持续性使该协议成为制备酯和酰胺的实用且经济上有吸引力的方法。

  homoisoflavonoid cores and structural analogs, were submitted for evaluation of antifungal activity against various species of Candida. The broth microdilution test was used to determine the Minimum Inhibitory Concentration (MIC) of the compounds and to verify the possible antifungal action mechanisms. The synthetic derivatives were obtained using various reaction methods, and six new compounds were obtained. The

  提交了一组 24 种具有香豆素和高异黄酮核心和结构类似物的合成衍生物，用于评估对各种念珠菌的抗真菌活性。肉汤微量稀释试验用于确定化合物的最低抑菌浓度 (MIC) 并验证可能的抗真菌作用机制。采用多种反应方法得到合成衍生物，得到六种新化合物。合成产物的结构通过FTIR光谱表征：1 H-NMR、13 C-NMR和HRMS。香豆素衍生物8表现出最好的抗真菌谱，表明香豆素环C-7位的戊氧基取代基可以增强生物活性。然后针对C.tropicis ATCC 13803 的生物膜对化合物8进行了评估，与生长对照组相比，在 0.268 µmol/mL 和 0.067 µmol/mL 的浓度下，生物膜的生物膜显着减少。为了更好地了解它们的抗真菌活性，化合物8和21对真菌细胞壁和质膜的作用方式进行了研究。据观察，两种化合物都没有直接与真菌质膜中的麦角甾醇或真菌细胞壁相互作用。这表明它们的生物活性是由于涉及其他药

  Many Gram-negative pathogens assemble adhesive structures on their surfaces that allow them to colonize host tissues and cause disease. Novel compositions which inhibit or prevent the formation of a pilus chaperone-subunit complex are disclosed. Interfering with the function of the pili chaperone negatively affects the chaperone/usher pathway which is one molecular mechanism by which Gram-negative bacteria assemble adhesive pili structures and thus prevent or inhibit pilus assembly. Also provided are methods for the treatment or prevention of diseases caused by tissue-adhering pilus-forming bacteria by inhibiting the function of pilus chaperones. Also provided are pharmaceutical preparations capable of inhibiting or preventing the formation of a pilus chaperone-subunit complex. Also provided are methods of synthesizing the N-substituted amino acid compounds and compounds useful for the synthesis thereof. In particular, novel fluorinated linker compounds and methods of synthesis are provided. Methods for using the fluorinated linker compounds in methods of solid-phase synthesis of the N-substituted amino acid compounds are also disclosed.
