Endogenous Bufadienolide, Blood Pressure and Alcohol Withdrawal

Current Hypertension Reviews, 2021
Background and Objective: Previously, it was demonstrated that marinobufagenin (MBG) is implicated in the development of ethanol withdrawal in rats. It has been shown that ethanol withdrawal is associated with a pressor response in the alcoholics. We hypothesized that elevated levels of sodium pump ligand, MBG, would underline the increase in systolic

High resolution mass spectrometry. Bufadienolides—II.

Organic Mass Spectrometry, 1972
AbstractComplete low resolution mass spectra and high resolution data for selected important peaks are presented and discussed for a series of naturally occurring 14β, 15β‐epoxybufadienolides (toad poisons) and their derivatives. The compounds examined were resibufogenin, marinobufagin, cinobufagin, desacetylcinobufagin, cinobufotalin ...

New bufadienolides from Urginea maritima sensu strictu

Fitoterapia, 2000
Two new bufadienolides, 11 alpha-acetylgamabufotalin 3-O-(4-O-beta-D-glucosyl)-alpha-L-rhamnoside (1) and 11 alpha-hydroxyscilliglaucoside (2), were isolated from bulbs of hexaploid Urginea maritima and identified by means of FAB-MS, (1)H-NMR and (13)C-NMR studies.

Structure of the bufadienolide bufotalin

Journal of the Chemical Society D: Chemical Communications, 1970
Mass spectral and 1H n.m.r. evidence, coupled with degradation of bufotalin to 3β-acetoxybufotalien (II), in turn prepared by total synthesis, provide unequivocal support for the assignment of structure (I) to bufotalin.

Antiviral Activity of Scillarenin, a Plant Bufadienolide

Japanese Journal of Microbiology, 1974
ABSTRACTAntiviral activity of scillarenin, a plant bufadienolide, and its mode of action were studied. Scillarenin selectively inhibited replication of picornaviruses, in particular, rhinovirus. At concentrations inhibiting rhinovirus replication, scillarenin had no effect on the synthesis of macromolecules in host cells.

Bufadienolides from Urginea pancration.

Planta medica, 2013
From bulbs of URGINEA PANCRATION (Steinh.) G. de Philippe (Hyacinthaceae) 5 bufadienolides were isolated by a combination of column and droplet counter-current chromatography; their structures were elucidated mainly by FAB-MS and (1)H- and (13)C-NMR spectroscopy.
