  Synthesis, Structure, and Neuroprotective Properties of Novel Imidazolyl Nitrones

  摘要：

  A new series of imidazolyl nitrones spin traps has been synthesized and evaluated pharmacologically. The salient structural feature of these molecules is the presence of an imidazole moiety substituted by aromatic or heteroaromatic cycles. This connectivity imparts to the nitrone superior neuroprotective properties in vivo and in parallel reduced side effects and toxicity. Thus compound 6a (a 2-phenylimidazolyl nitrone) administered intraperitoneally protects (80%) mice from lethality induced by an intracerebroventricular administration of tert-butyl hydroperoxide (t-BHP) an oxidant capable of inducing neurodegenerative processes. Administration of the archetypal nitrone phenyl-tert-butyl nitrone (PBN) at an equimolar dose also affords some protection (60%) in this test. However, this activity is accompanied by hypothermia, whereas no such effect is apparent for 6a. Moreover, previously prepared nonsubstituted or alkyl-substituted imidazolyl nitrones were shown to be extremely toxic to rats in contrast to the compounds prepared in this study. The observed activities in vivo correlate well with the calculated partition coefficients (ClogP) and HOMO energy level.

  several beta-lactamase inhibitors such as clavulanic acid, sulbactam, and tazobactam are widely used in the clinic in combination with beta-lactam antibiotics. However, single point mutations within these enzymes have allowed bacteria to overcome the inhibitory effect of the commercially approved beta-lactamase inhibitors. Although the commercially available beta-lactamase inhibitor/beta-lactam antibiotic

  β-内酰胺酶是细菌产生的丝氨酸和金属依赖性酶，可防御β-内酰胺抗生素。细菌产生的A类，B类和C类酶使得在某些情况下使用β-内酰胺类抗生素无效。为了克服对β-内酰胺抗生素的抗药性，几种β-内酰胺酶抑制剂（例如克拉维酸，舒巴坦和他唑巴坦）与β-内酰胺抗生素联合用于临床。但是，这些酶中的单点突变使细菌克服了商业认可的β-内酰胺酶抑制剂的抑制作用。尽管市售的β-内酰胺酶抑制剂/β-内酰胺类抗生素组合物对产生A类细菌和许多扩展谱的β-内酰胺酶（ESBL' s）产生细菌，它们对表达C类酶的细菌效果较差。为了避免这个问题，基于模型研究，合成了几种新型咪唑取代的6-亚甲基-青霉烯衍生物，并针对产生各种β-内酰胺酶的分离物进行了测试。本文研究了这些化合物的合成和构效关系（SAR）。
