  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.

  摘要：

  合成了一系列取代的2,2'-bi-1H-咪唑和相关类似物，并评估了其正性肌力。基于非经典生物等位线方法的结构活性关系研究表明，咪唑环之一上的氰基必须具有所需的药理特性。4（5）-Cyano-2,2'-bi-1H-咪唑（15a）是该系列中最有效的正性肌力药。在麻醉狗中，0.16 mg / kg iv时左心室dP / dt增加25％（ED25％= 0.16 mg / kg），在1 mg / kg iv时左心室收缩力增加60％。化合物15a是分离自犬心的IV型环状核苷酸磷酸二酯酶的良好抑制剂，具有与氨力农相似的效力。5'-cyano-2,4'-bi-1H-咪唑（44）和4-cyano-2,4' -bi-1H-咪唑（48）具有正性肌力活性。另外，两种可能的1,1'-二甲基氰基-2,2'-bi-1H-咪唑（24和25）是不活泼的，表明酸性NH和氰基对于正性肌力活性至关重要。

  A series of substituted 2,2'-bi-1H-imidazoles and related analogues was synthesized and evaluated for inotropic activity. Structure-activity relationship studies based on a nonclassical bioisosteric approach indicated the necessity of a cyano group on one of the imidazole rings to obtain the desired pharmacological profile. 4(5)-Cyano-2,2'-bi-1H-imidazole (15a) was the most potent inotropic agent in
