  1H-Imidazo[4,5-c]quinolin-4-amines: novel non-xanthine adenosine antagonists

  摘要：

  On the basis of a model we recently developed for the antagonist binding site of the adenosine A1 receptor (J. Med. Chem. 1990, 33, 1708-1713), it was predicted that H-1-imidazo[4,5-c]quinolin-4-amines would be antagonists of the A1 receptor. Furthermore, it was expected that certain hydrophobic substitutions at the 2- and 4-positions would enhance affinity. Here, we report on the synthesis and the adenosine A1 and A2 recpetor affinity of substituted H-1-imidazo[4,5-c]quinolin-4-amines. Some of these compounds have nanomolar affinity for the A1 receptor. The structure-activity relationships (SAR) of these compounds are discussed in relation to SAR for other adenosine receptor ligands. The H-1-imidazo[4,5-c]quinolin-4-amines constitute a novel class of non-xanthine adenosine antagonists.

  Novel synthetic procedures for C2 substituted imidazoquinolines as ligands for the α/β-interface of the GABAA-receptor

  摘要：

  摘要 通过两种合成方法制备了一系列取代的咪唑喹啉类化合物，这些化合物在结构上与吡唑喹啉酮类化合物（一类著名的 GABAA 配体）相关，并对这两种方法的效率进行了比较。一种方法依赖于经典的杂环合成，另一种方法旨在通过直接 C-H 功能化对截短的支架进行后期装饰。药理评估显示，合成的一种衍生物对含有α1β3受体亚型的受体具有有趣的活性。 图表摘要

  synthesized and evaluated as benzodiazepine receptor ligands. Affinity to the receptors was greatly affected by the bulkiness of the aryl group at the 2-position, compared to the pyrazoloquinolines such as CGS-9896. Derivatives with an isoxazole moiety at the 2-position showed high binding affinity and in vivo activity. In the imidazo[4,5-c]quinoline series, substitution at the 6-position decreased or abolished

• Preliminary evaluation of a 3H imidazoquinoline library as dual TLR7/TLR8 antagonists

  Toll-like receptors (TLR) -7 and -8 are thought to play an important role in immune activation processes underlying the pathophysiology of HIV and several clinically important autoimmune diseases. Based on our earlier findings of TLR7-antagonistic activity in a 3H imidazoquinoline, we sought to examine a pilot library of 3H imidazoquinolines for dual TLR7/8 antagonists, since they remain a poorly explored chemotype. 2D-NOE experiments were employed to unequivocally characterize the compounds. A quinolinium compound 12, bearing p-methoxybenzyl substituents on N3 and N5 positions was identified as a lead. Compound 12 was found to inhibit both TLR7 and TLR8 at low micromolar concentrations. Our preliminary results suggest that alkylation with electron-rich substituents on the quinoline N5, or conversely, elimination of the fixed charge of the resultant quaternary amine on the quinolinium may yield more active compounds.
