Up till now, studies have not been conducted on how the combination of Quercetin (Q), Aconitine (A) and apoptosis induction affects human cervical carcinoma HeLa cells. The result of our findings shows that the combination of Q and A (QA) is capable of synergistically inhibiting the proliferation of HeLa cells in a number of concentrations. QA synergistically inhibits the proliferation of MDR1 gene in the HeLa cells. It is concluded based on our result that QA induces apoptosis and ER stress just as QA-induced ER stress pathway may mediate apoptosis by upregulating mRNA expression levels of eIF2α, ATF4, IRE1, XBP1, ATF6, PERK and CHOP in the HeLa cells...

BACKGROUND: Aconitum alkaloids from Aconitum species are often used to treat arthritis and rheumatic diseases but have the drawback of high toxicity. Identifying their pharmacokinetic behaviour is important for the safe clinical application of Aconitum species. Efflux transporters (ETs), including P-glycoprotein (P-gp), multidrug resistance-associated protein 2 (MRP2), and breast cancer resistance protein (BCRP), have important functions in regulating the pharmacokinetic behaviours of drugs and in herb-herb or herb-drug interactions (HDIs)...

Aconitum carmichaelii is an important medicinal herb used widely in China, Japan, India, Korea, and other Asian countries. While extensive research on the characterization of metabolic extracts of A. carmichaelii has shown accumulation of numerous bioactive metabolites including aconitine and aconitine-type diterpene alkaloids, its biosynthetic pathway remains largely unknown. Biosynthesis of these secondary metabolites is tightly controlled and mostly occurs in a tissue-specific manner; therefore, transcriptome analysis across multiple tissues is an attractive method to identify the molecular components involved for further functional characterization...

To determine the cause of death in myocardial ion channel diseases (MICD)-induced sudden cardiac death (SCD) cases is a difficulty in forensic identification practices. The majority of MICD-induced SCD cases would experience lethal ventricular tachyarrhythmia (LVTA) before deaths; thus, confirming the occurrence of LVTA in bodies can offer a key evidence to identify these cases. Several lipids in the myocardia were found disturbed after LVTA; yet, whether serum lipidome would be disrupted by LVTA is not clear...

Yoshitake Nishiyama, Satoshi Yokoshima, Tohru Fukuyama
A synthesis of cardiopetaline has been accomplished via a Wagner-Meerwein rearrangement of a diol having the denudatine skeleton. The Wagner-Meerwein rearrangement could be facilitated simply by heating the diol with p-toluenesulfonic acid in pivalic acid, without preactivating the pivotal hydroxy group. This strategy does not require differentiation of several hydroxy groups in the substrate for the Wagner-Meerwein rearrangement and could be applied to the synthesis of more highly oxygenated aconitine-type diterpenoid alkaloids...

Andrographolide has a protective effect on the cardiovascular system. To study its cardic-electrophysiological effects, action potentials and voltage-gated Na(+) (INa), Ca(2+) (ICaL), and K(+) (IK1, IKr, Ito and IKur) currents were recorded using whole-cell patch clamp and current clamp techniques. Additionally, the effects of andrographolide on aconitine-induced arrhythmias were assessed on electrocardiograms in vivo. We found that andrographolide shortened action potential duration and reduced maximum upstroke velocity in rabbit left ventricular and left atrial myocytes...

Although Kampo medicine is now fully integrated into the modern Japanese healthcare system, most Kampo formulations depend on imported crude drugs from limited foreign areas. To prepare for possible shortages of crude drugs in the future, a wider scope for the supply of medicinal plants is necessary. We conducted field research and collaborated with international laboratories for phylogenic analysis and evaluation of medicinal plant resources. Our research on ephedra plants from a wide region of Eurasia has, for example, confirmed their phylogenic structure: based on DNA sequencing analysis of nuclear ribosomal internal transcribed spacer region 1 (ITS1) as well as the chloroplast intergenic spacer between trnL and trnF (trnL-F), the 8 major Chinese species and related plants grown on the continent could be divided into 3 groups...

The roots of Aconitum carmichaelii Debx. show excellent effects against rheumatism and cardiovascular diseases, but the effective compounds, C19-diester and monoester diterpenoid alkaloids (DDAs and MDAs) are toxic for their narrow therapeutic windows. It is noteworthy to investigate intestinal metabolism of these toxic compounds mainly by oral administration, because gut also express drug-metabolizing enzymes as well as liver. This study initially focused on phase I and phase II metabolism of DDAs (including aconitine, mesaconitine and hypaconitine) and MDAs (including benzoylaconine, benzoylmesaconine and benzoylhypaconine) in human intestine microsomes (HIM), with comparison of metabolism in human liver microsomes (HLM)...

We report about an acute monkshood intoxication requiring acute resuscitation in suicidal intent in a 56-year-old patient. The Blue Monkshood (Aconitum napellus) is considered to be the most toxic plant in Europe. All plant parts contain the highly toxic alkonoid aconitin. The lethal dose in adults is 2 - 6 mg. Intoxications are often fatal. Asymptomatic patients with suspected monkshood intoxication should also be monitored on an ICU. First signs of intoxication are paraesthesia in the mouth and throat area, abdominal cramps, nausea, vomiting and severe pain in skeletal muscle...
