متن کاملMegistolactone, a new alkaloid from Sarcomelicope megistophylla.
A new quinolone alkaloid, megistolactone (1) was isolated from the bark of Sarcomelicope megistophylla. Its structure has been elucidated on the basis of MS and NMR data. From a biogenetic point of view, this compound should be considered as an oxidation product of 1,2,3,4-tetra-O-subsituted acridone alkaloids, which are also present in the bark.
متن کاملA benzophenanthridine alkaloid, chelerythrine induces apoptosis in vitro in a Dalton's lymphoma.
PURPOSE The aim of this study was to investigate the effect of chelerythrine on DL cell apoptosis in an in vitro experimental setup. MATERIALS AND METHODS For tumor model, spontaneous occurring T-cell lymphoma designated as Dalton's lymphoma (DL) was selected. Double staining, transmission electron microscope (TEM), fluorescence microscopy, Western blotting, Reverse Transcriptase-Polymerase C...
متن کاملA new alkaloid from Fritillaria ussuriensis Maxim.
Pingbeimunone A (1), a new compound, together with the known ussuriedine (2), benzo[7,8]fluoreno[2,1-b]quinolizine cevane-3,6,16,20-tetrol (3), ebeiedinone (4), pingbeimine C (5) and verticine (6) were isolated from Fritillaria ussuriensis. The structure was elucidated on the basis of spectral analysis (IR, NMR and MS spectroscopy). In addition, their AChE inhibitory activities were also tested.
