Process To Obtain Dibenzylbutyrolactonic, Tetrahydrofuranic Lignans And Their Synthetic And Semi-Synthetic Derivatives, Their Analgesic And Anti-Inflammatory Activities, Topical And/Or Systemic Formulations Containing Said Lignans And Their Respective Therapeutic Method

摘要

A process to obtain dibenzylbutyrolactonic lignans from (-)-cubebin, isolated from a Piperaceae, especially Piper cubeba, and from (-)-methylpluviatolide, isolated from a Rutacea, especially Zanthoxylum naranjillo; their synthetic and semi-synthetic derivatives and tetrahydrofuranic lignans, such as galgravin and veragensin, isolated from Nectandra megapotamica, as well as the analgesic and anti-inflammatory activities of said lignans, and the topical and/or systemic formulations. Also presented is a therapeutic method using topic and/or systemic formulations based on said lignans for the treatment of inflammation and/or pain. Further, a process to obtain synthetic and semi-synthetic derivatives of (-)-cubebin, such as: (-)—O-acetyl cubebin; (-)—O-methyl cubebin; (-)—O—(N,N-dimethylamino-ethyl)-cubebin; (-)-hinokinin; (-)-6,6′-dinitroinokinin; (-)—O-benzyl cubebin; (-)-6,6′-diaminohinokinin and other synthetic derivatives which may be obtained, and synthetic and semi-synthetic derivatives of (-)-methylpluviatolide, such as (-)-6,6′-dinitromethylpluviatolide and (-)-6,6′-diaminomethylpluviatolide, to be used in the manufacture of medicine that has analgesic and anti-inflammatory activity is presented.
