Synthesis of quinolinomorphinan derivatives as highly selective δ opioid receptor ligands
摘要:
We have reported previously the novel delta opioid agonist KNT-127 which showed high affinity and selectivity for the delta receptor. Moreover, the analgesic effect of subcutaneously administered KNT-127 was more potent than that of a prototypical delta agonist (-)-TAN-67 in the acetic acid writhing test. This study of the structure-activity relationship of KNT-127 derivatives focused on the introduction of substituents onto the 5'-, 6'-, 7'- or 8'-position of the quinoline ring and revealed that many derivatives with 5'- or 8'-substituents showed high affinities and selectivities for the delta receptor. Especially, SYK-153 with an 8'-OH group showed the highest affinity and the most balanced and highest selectivity for the delta receptor among the synthesized compounds. (C) 2012 Elsevier Ltd.

A general strategy for the identification of selective cholesterol transport protein inhibitors through the synthesis of a diverse sterol-inspired compound collection is presented. Fusion of a primary sterol scaffold to diverse secondary natural product-derived scaffolds afforded hits against all of the Aster family of cholesterol transport proteins and selective inhibitors of Aster-C.

Quinoline derivatives are important natural products and pharmaceuticals, but their synthesis can be challenging due to poor yields, harsh reaction conditions, and instability of starting materials. Here we report the chemoenzymatic synthesis of quinaldic acids under mild conditions using an aldolase, trans-o-hydroxybenzylidenepyruvate hydratase-aldolase (NahE, or HBPA). A series of 2-aminobenzaldehydes
喹啉衍生物是重要的天然产物和药物,但由于收率低、反应条件苛刻和起始材料不稳定,它们的合成具有挑战性。在这里,我们报告了使用醛缩酶、反式-o-羟基亚苄基丙酮酸水合酶-醛缩酶(NahE 或 HBPA)在温和条件下化学酶法合成喹哪二酸。在 NahE 存在下,一系列源自相应硝基类似物还原的 2-氨基苯甲醛与丙酮酸反应,以高达 93% 的分离产率得到取代的喹啉。该反应不同于体内NahE 催化的羟醛缩合,而是类似于由其同源物二氢吡啶二羧酸合酶催化的杂环形成。

2-(1H)-oxoquinolines bearing different acidic functions in the 3-position. Exploiting these SAR, we were able to identify 6,7-dichloro-2-(1H)-oxoquinoline-3-phosphonic acid compound 3 (S 17625) as a potent, in vivo active AMPA antagonist. Unfortunately, during the course of the development, nephrotoxicity was manifest at therapeutically effective doses. Considering that some similitude exists between S 17625 and

(spiro-pyrrolidine) organocatalyst has been demonstrated to enable an asymmetric aza-Michael/Michael/aldol cyclization cascade, in which two six-membered rings (B/C) and three stereocenters have been constructed in a catalytic one-step process. It is so far the most efficient method for construction of hydrophenanthridine derivatives featuring high enantioselectivity. The trans- or cis-fused B/C-rings
已证明新开发的SPD(螺吡咯烷)有机催化剂可实现不对称的aza-Michael / Michael / aldol环化级联反应,在该催化反应中,两个六元环(B / C)和三个立体中心被构建步骤过程。迄今为止,这是构建具有高对映选择性的氢菲啶衍生物的最有效方法。的反式-或顺式-融合B / C环可以选择性地在一个基片控制的方式组装。此外,该级联反应可以放大至克级,而不会损失对映选择性。
