Synthesis and pharmacological activity of O-aminoalkyl derivatives of 7-hydroxycoumarin
摘要:
A series of novel O-aminoalkyl substituted 7-hydroxycoumarins were synthesized and evaluated for antibacterial and anticancer toxicity. Two different synthetic procedures, conventional and microwave assisted were used, and the structures of the compounds were confirmed by IR. H-1, C-13 NMR and MAS spectroscopic data. The molecular and crystal structures of 8-acetyl-7-(2-(1-morpholino)ethoxy) 4-methylchromen-2-one in solid state were analyzed by single crystal X-ray diffraction. The compound crystallizes in the monoclinic space group P2(1)/c. The main driving forces for the supramolecular structure are the C-H center dot center dot center dot O hydrogen bonds and the it pi...pi it intermolecular interactions. The most active compounds are those, where the O-aminoalkyl substituent has N,N-diethylamino part, and acetyl group is at C6 or at C8 atoms. (C) 2011 Elsevier Masson SAS. All rights reserved.

The synthesis and biological evaluation of a series of alpha, alpha-bis[(dialkylamino)alkyl]phenylacetamides, 2, are presented. These compounds are structurally related to the antiarrhythmic agent disopyramide (1) and in many cases were found to possess greater antiarrhythmicactivity in coronary ligated dogs. Within this series of compounds, a separation of the antiarrhythmic properties from the unwanted
Es wird dieDarstellungvon Dimethylamino-, Piperidino- und α-Pipecolino-äthyläthern einiger α-substitutierter Benzylalkohole beschrieben. Die hergestellten Verbindungen besitzen alle Antihistamin und spasmolytische Wirkung. Ihre Antihistaminwirkung steht etwas hinter derjenigen des Benadryls zurück, während die antagonistische Wirkung gegen Acetylcholin-Spasmen von der gleichen Grössenordnung ist

Novel .alpha.-aryl-.alpha.,.alpha.-bis[.omega.-(disubstituted amino)alkyl]acetamides are described herein. The compounds are useful as anti-arrhythmic agents. The compounds are prepared by reacting an appropriate disubstituted acetonitrile with an appropriate haloalkyl amine and subsequently hydrolyzing the resulting nitrile with concentrated sulfuric acid.
