provide a more detailed view on the structure⁻antimycobacterial activityrelationship (SAR) of phenylcarbamic acid derivatives containing two centers of protonation, 1-[2-[([2-/3-(alkoxy)phenyl]amino}carbonyl)oxy]-3-(dipropylammonio)propyl]pyrrolidinium oxalates (1a⁻d)/dichlorides (1e⁻h) as well as 1-[2-[([2-/3-(alkoxy)phenyl]amino}carbonyl)oxy]-3-(di-propylammonio)propyl]azepanium oxalates (1i⁻l)/dichlorides
研究了实验log kw数据集,以及主要基于原子或原子与碎片结合原理通过各种方法生成的分配系数的计算对数(log P)。通过非标度主成分分析(PCA)分析了实验性和计算机模拟的亲脂性描述子之间的异同。检查化合物1a⁻p的体外活性是否与结核分枝杆菌CNCTC My 331/88(分别与H37Rv和ATCC 2794相同),结核分枝杆菌H37Ra ATCC 25177,堪萨斯分枝杆菌CNCTC My 235/80(与ATCC 12478相同) ),堪萨斯分枝杆菌6509/96临床分离株,堪萨斯分枝杆菌DSM 44162,鸟分枝杆菌CNCTC My 330/80(与ATCC 25291相同),耻垢分枝杆菌ATCC 700084和海藻分枝杆菌CAMP 5644。还测试了分枝杆菌对参考药物异烟肼,乙胺丁醇,氧氟沙星或环丙沙星的体外敏感性。该研究的一个非常独特的方面是,来自1a⁻p的许多化合物几乎对所有
Untersuchungen an Lokalanästhetika, 99. Mitt.: Synthese und lokalanästhetische Wirkung von Alkoxyphenylcarbamaten
der Gruppe der 1‐Propoxymethyl‐2‐(1‐pyrrolidinyl)‐, 2‐(1‐Piperidino)‐und 2‐(1‐Perhydroazepinyl)‐ethylester der o‐ und m‐Alkoxyphenylcarbamidsäure hergestellt. Die untersuchten Verbindungen wiesen bei verhältnismäßig geringer akuter Toxizität hohe relative anästhetische Aktivität im Vergleich mit den Standardverbindungen Cocain und Procain auf.

stereoselective reactions. The chemical structures of these compounds were confirmed by ¹H-NMR, ¹³C-NMR and IR spectroscopy and their physico-chemical properties were characterized. The two new series of diastereomeric compounds were tested for their localanestheticactivity and parabolic relationship between the localanestheticactivity and lipophilicity was found for both cis- and trans-series.
