  摘要：

  合成了31个双-（苯并咪唑、苯并噻唑和苯并恶唑）化合物与钛（IV）金属中心的配合物，进行了表征，并用甲基铝氧烷（MAO）激活，然后测试了其在催化乙烯聚合中的活性。各种催化剂的活性被发现与配体框架中的杂原子有关。39 / MAO获得了最高活性（573 kg PE / mol cat. h）。所产生的聚乙烯具有高分子量（最高可达1.5 × 10^6 g/mol）和宽的分子量分布（PD = 65）。这可能是由于MAO反离子与催化剂配体中的杂原子之间不同的相互作用生成了不同的活性位点。

  In an attempt to design and synthesize a potent class of antimicrobials, 1,2-phenylenediamine derivatives were reacted with various aliphatic and heteroaliphatic dicarboxylic acids to generate a small library of 26 head-to-head bisbenzimidazole compounds (16 – 42) using the polyphosphoric acid method. These compounds were screened for their antibacterial activity and their antifungal activity. Compound 25 showed maximum potency against both Gram-positive and Gram-negative bacterial strains with minimum inhibitory concentration (MIC) values in the range of 7.81 – 31.25 μg/mL. In particular, it showed the maximum MIC values of 7.81 μg/mL against Gram-negative bacteria, which was four-fold more active than the standard drug ampicillin (MIC = 32.25 μg/mL). Compound 19 was found to be the most active against S. aureus with a MIC value of < 3.90 μg/mL, whereas the remaining compounds showed only low-to-moderate activity. Furthermore, all compounds exhibited low activity against all fungal strains in comparison to the standard drug fluconazole. I addition, pharmacophore hypotheses were generated to analyze structure–activity relationships between the molecular structures and antimicrobial activities on E. coli. This pharmacophore model can be useful in order to design new antimicrobial drugs. It can be suggested that the substitution of a phenyl ring at the 5/6 and 5′/6′ positions in symmetric bisbenzimidazole derivatives produces compounds with promising antimicrobial activity.

  为了设计并合成一类高效的抗菌药物，我们通过多磷酸法，将1,2-苯二胺衍生物与各种脂肪族和杂脂肪族二羧酸反应，生成了一个包含26个头对头双苯并咪唑化合物（16 – 42）的小型库。这些化合物经过筛选，评估了它们的抗菌活性和抗真菌活性。化合物25对革兰氏阳性和革兰氏阴性细菌株显示出最高的活性，其最低抑制浓度（MIC）值在7.81至31.25 μg/mL范围内。特别是，它对革兰氏阴性细菌显示出最高的MIC值7.81 μg/mL，比标准药物氨苄西林（MIC = 32.25 μg/mL）高出四倍。化合物19对金黄色葡萄球菌显示出最高的活性，其MIC值小于3.90 μg/mL，而其他化合物仅显示出低至中等的活性。此外，与标准药物氟康唑相比，所有化合物对所有真菌株均显示出低活性。此外，生成了药效团假设，以分析大肠杆菌上的分子结构与抗菌活性之间的结构-活性关系。这个药效团模型对于设计新的抗菌药物可能非常有用。可以建议，在对称双苯并咪唑衍生物的5/6和5′/6′位置上取代苯环会产生具有有前景的抗菌活性的化合物。

  Thirty-one complexes of bis-(benzimidazole, benzothiazole, and benzoxazole) compounds with Zr(IV) metal centers were synthesized, characterized, activated with methylaluminoxane (MAO), and then tested for catalytic ethylene polymerization. The activities of the various catalysts were found to be functions of the heteroatoms in the ligand frameworks and the structure around the active metal center. The highest activity was obtained with 38/MAO (424 kg E/mol cat. h). The produced polyethylenes showed high molecular weights (41/MAO, 1.9 x 10(6) g/mol) and broad molecular weight distributions (38/MAO, M-omega = 9.64 x 10(5) g/mol, PD = 23). This could result from different interactions of the MAO counter ion with the heteroatoms of the catalyst ligand generating different active sites.

  31 complexes of bis - (benzimidazole, benzothiazole and benzoxazole) compounds with Ti (IV) metal centers were synthesized, characterized, activated with methylalumoxane (MAO) and then tested for catalytic ethylene polymerization. The activities of the various catalysts were found to be functions of the hetero atoms in the ligand frameworks. The highest activity was obtained with 39 / MAO (573 kg PE / mol cat. h). The produced polyethylenes showed high molecular weights (up to 1.5 ×106 g/mol) and broad molecular weight distributions (PD = 65). This could result from different interactions of the MAO counterion with the heteroatoms of the catalyst ligand generating different active sites.
