项目摘要
Professor Bruce C. Gibb in the Department of Chemistry at the University of New Orleans is supported by the Organic and Macromolecular Chemistry Program for his studies on the synthesis of resorcinol-based cavitands, determination of binding constants with various small "guest" substrates, incorporation of a Zn(2+) catalytic site into the cavitand, and evaluation of these supramolecular hosts' ability to catalyze the hydrolysis of ester substrates. The regioselective hydrolysis of diester guests based on the characteristics of the binding site will also be explored.With the support of the Organic and Macromolecular Chemistry Program, Professor Gibb will prepare a series of large, cyclic organic compounds which have the capacity to bind to various smaller substrates. A catalytic active site similar to that found in the enzyme, carbonic anhydrase, will then be attached to the cyclic host compound. These enzyme mimics will be evaluated for their ability to catalyze a similar reaction to that of the natural enzyme. By varying the characteristics of the cyclic host's binding cavity, different substrates will be bound to the hosts with varying affinities. This in turn will affect the catalytic rate of these compounds with various substrates.
布鲁斯教授C. Gibb在新奥尔良大学化学系的研究得到了有机和大分子化学计划的支持,他研究了间苯二酚基空穴的合成,测定了与各种小“客体”底物的结合常数,将Zn(2+)催化位点掺入空穴,并评估了这些超分子宿主催化酯底物水解的能力。 在有机和大分子化学计划的支持下,Gibb教授将制备一系列大的环状有机化合物,这些化合物具有与各种较小底物结合的能力。 一个类似于在酶中发现的催化活性位点,碳酸酐酶,然后将连接到环状主体化合物。 将评价这些酶模拟物催化与天然酶类似反应的能力。 通过改变环状主体结合腔的特征,不同的底物将以不同的亲和力结合到主体上。 这反过来将影响这些化合物与各种底物的催化速率。
