Cyclooxygenase-2 Inhibitory 1,4-Naphthoquinones from Impatiens balsamina L.
摘要:
在两种新的 1,4-萘醌钠盐(3-羟基-2{[3-羟基-1,4-二氧代(2-萘基)]乙基钠}萘-1、4-二酮(imatienolate)钠盐(1)和 2-羟基-3-(2-羟乙基)萘-1,4-二酮(balsaminolate)钠盐(2),它们是从 Impatiens balsamina L.(凤仙花科植物)的花冠中分离出来的。(凤仙花科)的花冠中分离出来。通过光谱技术阐明了它们的结构。我们的研究结果为使用 I. balsamina L. 治疗关节风湿、疼痛和肿胀提供了证据。

method, the electrochemical oxidation of primary alcohols to the corresponding aldehydes have taken at anode and the reduction of β-diketones to active methylene compounds has happened in cathode. In next step, the cathodically activated methylene reacts with anodically generated aldehyde. Different types of bis-β-diketones have been synthesized using C1–C5 primary alcohols and different β-diketones
