Inhibitors of adenosine 3',5'-cyclic monophosphate phosphodiesterase in Daphne genkwa Sieb. et Zucc.
Adenosine 3',5'-cyclic monophosphate (cAMP) phosphodiesterase inhibition testing provides a useful means for the screening of biologically active compounds contained in medicinal plants. We have identified cAMP phosphodiesterase inhibitors contained in various medicinal plants.2a-k) The present paper deals with the identification of cAMP phosphodiesterase inhibitors contained in the flowers and...
متن کاملA New Megastigmane Sesquiterpenoid from Zanthoxylum Schinifolium Sieb. et Zucc.
Zanthoxylum schinifolium Sieb. et Zucc. (Rutaceae), a dioecious shrub with hooked prickly branches, has been used as folk medicine for the treatment of the common cold, stomach ache, diarrhea, and jaundice in China, Korea, and Japan. In our phytochemical investigations on this genus, a new megastigmane sesquiterpenoid, which is referred to as schinifolenol A (1), was isolated from Z. schinifoli...
متن کاملA new approach to the characterization of steroids containing the 17-alpha-ketol side chain.
When only minute quantities of a steroid are available for analysis, paper or thin-layer chromatography is frequently used to identify the compound and its derivatives. Most modifications of this approach require co-chromatography of a known steroid treated in a manner similar to the unknown. Occasionally, because a steroid is new or rare, a standard may not be available for comparison. Bush (1...
متن کاملPlatanionosides D-J: megastigmane glycosides from the leaves of Alangium platanifolium (Sieb. et Zucc.) Harms var. platanifolium Sieb. et Zucc.
From the leaves of Alangium paltanifolium var. platanifolium, collected in Fukuoka Prefecture, twelve further megastigmane glycosides were isolated. Seven of them, named platanionosides D-J (1-7), were found to be new compounds. Their structures were elucidated from spectroscopic evidence and their absolute structures were determined from beta-D-glucosylation-induced shift trends of 13C-NMR and...
