  Dimerization of 2-pyridylisonitriles produces π-extended fused heteroarenes useful as highly selective colorimetric and optical probes for copper ion

  摘要：

  A very simple synthesis of pyrido[2 '',1 '':2',3']imidazo[4',5':4,5]imidazo[1,2-a]Pyridines 2 was achieved from the dimerization of 2-pyridylisonitriles. The optical responses of these pi-extended fused heteroarenes to a series of metal ions were investigated by means of UV-visible absorption spectrum in acetonitrile. It was found that most of compounds 2 selectively responded to Cu2+, and the limit of detection was about 3.5 x 10(-7) M when using the best probe, 3,9-dimethylpyrido[2",1":2',3']imidazo[4',5':4,5] imidazol1,2-a]pyridine 2d. Meanwhile some compounds 2 specifically showed a color change from colorless to red or yellow when they are exposed to copper ion in acetonitrile, whereas other transitional, alkali and alkaline earth metal ions could not induce a color change. This work not only established a direct access to pi-extended fused heteroarenes, but also supplied novel sensitive and selective colorimetric and optical probes for copper ion.

  公开（公告）日：2010-11-04

  This invention provides novel β-lactamase inhibitors of the aryl- and heteroarylsulfonamidomethylphosphonate monoester class having nitrogen-based cations or quarternary ammonium groups. The compounds inhibit three classes of β-lactamases and synergize the antibacterial effects of β-lactam antibiotics (e.g., imipenem and ceftazidime) against those micro-organisms normally resistant to the β-lactam antibiotics as a result of the presence of the β-lactamases. Formula (I) or pharmaceutically acceptable salt thereof.

  这项发明提供了一种新型的β-内酰胺酶抑制剂，属于芳基和杂芳基磺酰胺基甲基膦酸单酯类，具有基于氮的阳离子或季铵基团。这些化合物抑制三类β-内酰胺酶，并增强β-内酰胺类抗生素（如亚胺培南和头孢他啶）对那些通常对β-内酰胺类抗生素具有抗药性的微生物的抗菌效果，这是由于β-内酰胺酶的存在。公式（I）或其药学上可接受的盐。

  Disclosed is a novel oxazolidinone derivative represented by Formula 1 above, in particular, a novel oxazolidinone compound having a cyclic amidoxime or cyclic amidrazone group. In Formula 1, R and Q are the same as defined in the detailed description. In addition, disclosed is a pharmaceutical composition for an antibiotic which includes the novel oxazolidinone derivative of Formula 1, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an active ingredient. The novel oxazolidinone derivative, the prodrug thereof, the hydrate thereof, the solvate thereof, the isomer thereof, and the pharmaceutically acceptable salt thereof have broad antibacterial spectrum against resistant bacteria, low toxicity and strong antibacterial effects against Gram-positive and Gram-negative bacteria and thus may be effectively used as antibiotics.

  上述公开了一种新型噁唑烷酮衍生物，具体来说，是一种具有环氧胺肟基或环氧胺酮基团的新型噁唑烷酮化合物。 在公式1中，R和Q的定义与详细描述中的相同。 此外，公开了一种抗生素药物组合物，包括公式1中的新型噁唑烷酮衍生物，其前药，水合物，溶剂合物，异构体或其药学上可接受的盐作为活性成分。 该新型噁唑烷酮衍生物，其前药，水合物，溶剂合物，异构体和其药学上可接受的盐对耐药细菌具有广泛的抗菌谱，毒性低，并对革兰氏阳性和阴性细菌具有强效的抗菌作用，因此可以有效地用作抗生素。

  This invention relates to agents that are inhibitors or activators of variant forms of endogenous proteins and novel methods of identifying such variants. Of particular interest are inhibitors and activators of endogenous protein variants, encoded by genes which have mutated, which variants often arise or are at least first identified as having arisen following exposure to a chemical agent which is known to be an inhibitor or activator of the corresponding unmutated endogenous protein.

  这项发明涉及的是抑制或激活内源性蛋白变异形式的试剂以及识别这些变异的新方法。特别感兴趣的是那些由突变基因编码的内源性蛋白变异的抑制剂和激活剂，这些变异通常是在暴露于已知是相应未突变内源性蛋白的抑制剂或激活剂的化学试剂之后出现，或者至少是首次被识别为由此类化学试剂引起的。
