Songorine isolated from Aconitum brachypodum Diels possesses prominent activity of inhibiting G protein-coupled receptors (GPCRs) in the early screening process. In this paper, a series of Songorine derivatives were synthesized and their inhibitory activities on GPCRs were also evaluated by using
Alkaloids are well-studied secondary metabolites, with recent preclinical studies evidencing that many of them exhibit anti-cancer, anti-depressant, anti-nociceptive, anti-inflammatory, anti-pyretic, anti-platelet, anti-oxidant, and anti-bacterial properties. Aconitum is a genus rich of diverse
1. The present study investigated the electrophysiological effects of songorine (1 100 microM), an alkaloid occurring in plants of the Aconitum genus, in rat hippocampal slices. 2. Songorine (10-100 microM) evoked a concentration-dependent increase in the amplitude of the orthodromic population
Songorine, a diterpenoid alkaloid isolated from the genus Aconitum, was recently found to enhance the excitatory synaptic transmission in rat hippocampus. The mechanism underlying the effects was examined in the present study. The alkaloid at 0.1-300 microM inhibited the specific binding of
In order to find the cardiotonic constituents of lateral roots of Aconitum carmichaelii Debx., the investigation was carried out. Silica gel column chromatography, Sephadex LH-20, medium-pressure MCI and reverse phase ODS column chromatography were used to separate the 90% EtOH extract of the
Amino alcohol alkaloids are the active components in the lateral root of Aconitum carmichaelii Debx. (Fuzi), and they have a variety of pharmacological activities. However, the chemical fingerprints of the ester alkaloids reported to date were mainly obtained from high-performance liquid
Aconitum carmichaelii Debeaux is a widely used herbal medicine, which has anti-inflammatory and analgesic activities. However, due to its high toxicity, poisoning incidents often occur all over the world. To systematically understand the pharmacokinetics (PK) and tissue distribution of A.
BACKGROUND
Metabolomics is an 'omics' approach that aims to comprehensively analyse all metabolites in a biological sample, and has great potential for directly elucidating plant metabolic processes. Increasing evidence supports the view that plants produce a broad range of low-molecular-weight
A new denudatine-type C20-diterpenoid alkaloid, designated as sinchianine (1), together with eight known diterpenoid alkaloids, 12-acetyl-12-epi-napelline (2), 12-epi-napelline (3), neoline (4), talatisamine (5), 14-O-acetylsenbusine A (6) and benzoylaconine (7), songorine (8) and aconitine (9),
As a representative variety of hypertoxic herbs, aconite has a very high medicinal value but certain security risks. With the advance of urbanization and industrial transfer and upgrading, traditional geo-authentic regions and emerging regions have gradually coexisted. However, there are significant
Four diterpenoid alkaloids, namely, (a) hypaconitine, (b) songorine, (c) mesaconitine and (d) aconitine, were isolated from the ethanol root extract of Aconitum carmichaelii Debx. The antiviral activities of these alkaloids against tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) were
Five constituents were isolated from Aconitum szechenyianum Gay. The structures of these compounds were identified as beta-sitosterol (I), aconitine (II), 3-acetylaconitine (III), songorine (IV) and a new compound whose structure was elucidated to be szechenyine (V) on the basis of UV, IR, 1HNMR,
We compared analgesic activities of individual alkaloids extracted from Baikal aconite (Aconitum baikalensis): napelline, hypaconitine, songorine, mesaconitine, 12-epinapelline N-oxide. The detected analgesic activity was comparable to that of sodium metamizole. The mechanisms of analgesia were
Aconitum species accumulate highly toxic diterpene alkaloids, which have attracted considerable interest because of their complex structure, interesting chemistry and noteworthy physiological effects. The authors carried out phytochemical analysis of two Aconitum species native to the Carpathian
We compared anti-inflammatory activity of individual diterpene alkaloids isolated from Aconitum baikalense (napelline, songorine, hypaconitine, mesaconitine, 12-epinapelline N-oxide) under conditions of acute inflammation of different genesis. The tested substances showed high antiexudative activity
