Anthranilic acid based CCK1 antagonists: the 2-indole moiety may represent a “needle” according to the recent homonymous concept
摘要:
Recently we described an innovative class of non-peptide CCK1 antagonists keeping appropriate pharmacophoric groups on the anthranilic acid employed as a molecular scaffold. The lead compound obtained, VL-0395, characterized by the presence of Phe and the 2-indole moiety at the C- and N-termini of anthranilic acid, respectively, is endowed with submicromolar affinity towards CCK1 receptors. Thus, we have prepared and tested on CCK receptors a library of VL-0395 analogues in order to investigate the precise topological and essential key interactions of the 2-indole group of the lead with the CCK1 receptor. The obtained results confirm that this group establishes very specific interactions with this receptor sub-site and may be viewed as a "needle" group. (C) 2003 Elsevier SAS. All rights reserved.
我们描述了使用钯催化分子间合成多取代环戊烯酮的一般策略。总体而言,该反应是通过涉及炔烃、α,β-不饱和酰氯(作为烯烃和一氧化碳来源)和氢硅烷的分子改组过程实现的,以产生三个新的 CC 键。这种新的无一氧化碳途径提供了具有优异产量的产品。此外,区域选择性是对环戊烯酮合成常规方法的补充。此外,还提出了一组区域和化学发散反应,以强调这种新策略的合成潜力。

Indenoylguanidines of formula I and formula II, the process for their preparation, their use as medicaments, medicaments containing them, their use as diagnostic agents and medicaments containing them are described. Compounds I are useful for treating cardiac arrhythmias. Further they are useful as cardioprotective agents in mammals, which comprises administering the compound of formula-I or II with the above properties in combination with pharmaceutically accepted carrier to said mammal. ##STR1##

Benzamides with tethered acetal groups undergo reactions in CF3SO3H to give ring-fused isoindolinones by a cyclization cascade. The reaction initially forms an N-acyliminium ion which then gives the isoindolinone by the aza-Nazarov reaction. An unusual variant also cyclizes at the allylic position. (C) 2010 Elsevier Ltd.
