  A new series of M3 muscarinic antagonists based on the 4-amino-piperidine scaffold

  摘要：

  A series of 4-amino-piperidine containing molecules have been synthesized and structure-affinity relationship toward the M3-muscarinic receptor has been investigated. Chemical modulations provided molecules with K-i for the human M3-R up to 1 nM with variable selectivity (3- to 40-fold) over the human M2-R. Compounds 2 (pA(2) = 8.3, 8.6) demonstrates in vitro on guinea pig bladder and ileal strips potent anticholinergic properties and tissue selectivity. (C) 2002 Elsevier Science Ltd.

  四种新颖的天然药物启发的支架用于药物开发的合成。

  摘要：

  受许多生物活性天然产物（如组织毒素）的新型螺旋结构的启发，已设计了一系列新型螺旋支架，并开发了稳健的合成方法。脚手架是现成的构建基块，可以轻松制备成5-20克的规模。它们含有两个氨基基团（一个受Boc保护的氨基基团），并且使用酰胺形成或还原性胺化步骤进行了设计，可轻松转换成铅生成库。以RCM为关键步骤，完成了1,9-二氮杂螺[5.5]十一烷和3,7-二氮杂螺[5.6]十二烷环的合成。据报道，有一种简单的后处理程序可以去除高度着色的钌残留物。1,8-二氮杂螺[4.的合成。5]癸烷支架是通过在酸性条件下使用溴介导的相应的4-氨基丁烯中间体的5-内基环化来实现的。这是要报道的这类环化反应的第一个例子。提出了一种新的机理，涉及从最初形成的溴离子到相邻氮原子的溴转移反应，这是这种反应在“正常”溴化条件下失败的原因。据报道，1-酰基-1，9-二氮杂螺[5.5]十一烷的异常重新排列为相应的9-酰基-1，9-二氮杂螺[5

  公开（公告）日：1995-10-18

  An 8-methoxyquinolonecarboxylic acid derivative represented by general formula (I), and optical isomers, pharmaceutically acceptable salts and hydrates thereof, wherein R₁ represents hydrogen, lower alkyl, phenylalkyl or an in vivo hydrolyzable ester residue; R₂ represents hydrogen or methyl; and n represents an integer of 0 or 1. This derivative has a wide antimicrobial spectrum based on the activity potentiated in vitro and in vivo against gram-positive bacteria while retaining the potent antibacterial activity of the conventional quinolonecarboxylate bactericides against gram-negative bacteria. Since it scarcely has problematic side effects and is reduced in toxicity, it is promising as a bactericide having more excellent clinical effects.

  通式(I)代表的 8-甲氧基喹啉羧酸衍生物及其光学异构体、药学上可接受的盐和水合物，其中 R₁ 代表氢、低级烷基、苯基烷基或体内可水解的酯残基；R₂ 代表氢或甲基；n 代表 0 或 1 的整数。根据体外和体内对革兰氏阳性菌的增效活性，这种衍生物具有广泛的抗菌谱，同时保留了传统喹啉羧酸盐杀菌剂对革兰氏阴性菌的强效抗菌活性。由于它几乎没有副作用，毒性也较低，因此有望成为一种临床效果更佳的杀菌剂。

• Spirocyclic Dihydropyridines by Electrophile-Induced Dearomatizing Cyclization of N-Alkenyl Pyridinecarboxamides

  日期：2013.4.19

  On treatment with acylating or sulfonylating agents, N-alkenyl pyridine carboxamides (N-pyridinecarbonyl enamines) undergo a dearomatizing cyclization initiated by pyridine acylation and followed by intramolecular trapping of the resulting pyridinium cation. The products are spirocyclic dihydropyridines which may be further elaborated to spirocyclic heterocycles with drug-like features.
