  Pyrrolylquinoxalinediones: A new class of AMPA receptor antagonists

  摘要：

  Pyrrolylquinoxalinediones were synthesized and their affinities for the AMPA receptor were determined. Most compounds showed moderate to good affinities. The acetic acid derivative 8b exhibited a K-i value of 70 nM and was equipotent to NBQX 1. Structure activity relationships are discussed. Selected compounds were tested for their potency to inhibit AMPA induced lethal convulsions in mice. In this in vivo model the compounds showed improved potency compared with NBQX.

  An efficient one‐pot reaction has been developed for the synthesis of 2,3‐dichloroquinoxaline derivatives 3a–n. The reaction was performed in two steps via a silica gel catalyzed tandem process from o‐phenylenediamine and oxalic acid, followed by addition of phosphorus oxychloride (POCl3). A variety of 2,3‐dichloroquinoxalines have been obtained in good to excellent overall yields. Eight known compounds

• A new small molecule inhibitor of soluble guanylate cyclase

  Soluble guanylate cyclase (sGC) is a haem containing enzyme that regulates cardiovascular homeostasis and multiple mechanisms in the central and peripheral nervous system. Commonly used inhibitors of sGC activity act through oxidation of the haem moiety, however they also bind haemoglobin and this limits their bioavailability for in vivo studies. We have discovered a new class of small molecule inhibitors

  可溶性鸟苷酸环化酶（sGC）是一种含有血红素的酶，可调节心血管稳态和中枢神经系统和周围神经系统的多种机制。常用的sGC活性抑制剂通过血红素部分的氧化起作用，但是它们也结合血红蛋白，这限制了它们在体内研究中的生物利用度。我们发现了一类新的sGC小分子抑制剂，并表征了名为D12（化合物10）的化合物，该化合物在SPR分析中以11μM的K D与酶的催化结构域结合。
