  Development of high-affinity 5-HT3 receptor antagonists. Structure-affinity relationships of novel 1,7-annulated indole derivatives. 1

  摘要：

  On the basis of the structures of ondansetron and GR 65,630, its ring-opened C-linked methylimidazole analogue, novel 1,7-annelated indole derivatives were synthesized as potential 5-HT3 antagonists. Receptor binding studies show that all compounds display a high affinity for the 5-HT3 receptors. In both series annelation results in compounds being 7 and 4 times more potent than the references ondansetron and GR 65,630, respectively. Similar to ondansetron, the 1,7-annelated indoles show little stereoselectivity. The (-)-isomers are only slightly more potent than the (+)-isomers. The receptor binding profile of l-10-[(2-methyl-1H-imidazol-1-yl)methyl]-5,6,8,9,10,11-hexahydro-4H-pyrido[3,2,1-jk]carbazol-11-one hydrochloride (24b) (INN cilansetron) shows that the compound displays, besides a high affinity for 5-HT3 receptors (K(i) = 0. 19 nM), a weak affinity for sigma-receptors (K(i) = 340 nM), muscarine M1 receptors (K(i) = 910 nM), and 5-HT4 receptors (K(i_ = 960 nM) and no affinity (K(i) greater-than-or-equal-to 5000 nM) for all the other receptor types tested (n = 37). The new compounds fit the proposed necessary chemical template for binding: a heteroaromatic ring system, a coplanar carbonyl group, and a nitrogen center at well-defined distances. The enhanced potency of the annelated 1,7-indole derivatives indicates that the extra ring provides a favorable hydrophobic area for interaction with the 5-HT3 receptor site. In vivo cilansetron is more potent and induces less central side effects than ondansetron. At present cilansetron is in clinical trials.

  7-氮杂双环[2.2.1]庚烷的脂肪族N-亚硝胺的结构特征促进N-NO键断裂

  摘要：

  N-亚硝胺可被视为潜在的一氧化氮 (NO)/亚硝基离子 (NO(+)) 供体。然而，N-亚硝胺的结构，特别是脂肪族 N-亚硝胺的结构与 NO 或 NO(+) 释放特征的关系仍不清楚。在这里，我们表明 7-氮杂双环 [2.2.1] 庚烷的脂肪族 N-亚硝基胺可以进行异裂 N-NO 键裂解。根据观察溶液中 N-NO 键的旋转势垒降低和固态 N-亚硝基的氮-锥体结构，我们假设 N-亚硝胺的 N-NO 键断裂通过减少 N-NO 基团的共振。计算研究表明 7-氮杂双环 [2.2.1] 庚烷的 N-亚硝胺的这些结构特征源自施加在 CNC 角上的角应变。

  N2O4 was supported on the cross-linked polyvinylpyrrolidone (PVP) to afford a solid, stable and recyclable nitrosating agent. This reagent shows excellent selectivity for N-nitrosation of dialkyl amines in the presence of diaryl-, arylalkyl-, trialkylamines and also for secondary amides in dichloromethane at room temperature under mild and heterogeneous conditions. Also N-nitroso-N-alkyl amides can be selectively prepared in the presence of primary amides and N-phenylamides under similar reaction conditions. Selective N-nitrosation or dealkylation and N-nitrosation of tertiary amines can also be performed by this reagent.

  been identified as versatile aerobic oxidation catalysts. Primary amines were readily cross-coupled with primary nitroalkanes via deaminative pathway to give nitroalkene derivatives in good to excellent yields. Secondary and tertiary amines were inert to ortho-naphthoquinone catalysts; however, secondary nitroalkanes were readily converted by ortho-naphthoquinone catalysts to the corresponding nitrite

  基于邻萘醌的有机催化剂已被鉴定为通用的好氧氧化催化剂。伯胺很容易通过脱氨途径与伯硝基烷烃交联，从而以良好或优异的收率得到硝基烯烃衍生物。仲胺和叔胺对邻萘醌催化剂是惰性的。然而，仲硝基烷烃很容易通过邻萘醌催化剂转化为相应的亚硝酸盐类，后者将胺原位氧化为相应的N。-亚硝基化合物。在不以化学计量的量使用刺激性氧化剂的情况下，本催化好氧氧化方案利用底物的混杂特性在温和的反应条件下提供了容易的胺氧化产物的通道。

• Transnitrosation by N-Aryl-N-nitrosoureas; NO-Carrying O-Nitrosoisourea.
  作者：Masayuki TANNO、Shoko SUEYOSHI、Naoki MIYATA

  DOI：10.1248/cpb.42.1760

  日期：——

  Transfer of nitroso groups, so-called transnitrosation, from aromatic N-nitroso compounds such as N-nitrosoureas, N-nitrosamides and N-nitrosamines, to aromatic amines or ureas was observed under non-acidic conditions at room temperature. Sterically hindered 3, 3-dibenzyl-1-(4-tolyl)-1-nitrosourea (1a) rapidly nitrosates indoline, N-alkylanilines or 3-methyl-1-(4-tolyl)urea to give their N-nitroso derivatives. In the case of N, N-dimethylanilines, nitrosative demethylation occurs to give N-methyl-N-nitrosanilines. The transnitrosation is accelerated by electron-releasing groups on the nitroso acceptors, N-alkylanilines. The transnitrosation mechanism is considered to be as follows : N-nitrosourea (1) thermally decomposes to nitric oxide and ureidyl radical followed by formation of an O-nitrosoisourea intermediate (10), which acts as an NO-carrying agent and nitrosates anilines or ureas.

  从芳香族N-亚硝基化合物（如N-亚硝基脲、N-亚硝基酰胺和N-亚硝基胺）向芳香族胺或脲转移亚硝基的过程，称为转亚硝基化，在室温下非酸性条件下被观察到。立体障碍的3, 3-二苯基-1-(4-甲基苯基)-1-亚硝基脲（1a）迅速与吲哚、N-烷基苯胺或3-甲基-1-(4-甲基苯基)脲发生亚硝化反应，生成其N-亚硝基衍生物。在N,N-二甲基苯胺的情况下，发生亚硝化去甲基化，生成N-甲基-N-亚硝基苯胺。转亚硝基化受到电子供体基团的促进，这些基团位于亚硝基接受体N-烷基苯胺上。转亚硝基化机制被认为如下：N-亚硝基脲（1）热分解生成一氧化氮和脲基自由基，随后形成O-亚硝基异脲中间体（10），后者作为NO载体，与苯胺或脲进行亚硝化。
