A new alkaloid of Aconitum karacolicum Rapcs, from the Ranunculaceae family, collected in Kirghizstan, was isolated from the roots of this plant, using a purification scheme based upon its in vitro antiproliferative properties against three human tumour cell lines in culture. Structural
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
Aconitum alkaloids including aconitine (AC), mesaconitine (MA), hypaconitine (HA), are highly toxic. Their hydrolysates, such as benzoylaconine (BAC), benzoylmesaconine (BMA), benzoylhypaconine (BHA), aconine, and mesaconine, are considerably less toxic. Efflux transporters, including P-glycoprotein
We recently synthesized from aconitine a series of drugs with in vitro and in vivo antitumor properties, among which bis[O-(14-benzoylaconine-8-yl)]suberate (BBAS) was the most active (Eur J Med Chem 2012; 54: 343). In the present work, we used the NCI panel of 60 human tumor cell lines to identify
A new denudatine-type C20-diterpenoid alkaloid, pubesine (1), along with seven known diterpenoid alkaloids, altaconitine (2), 14-benzoylaconine (3), spicatine A (4), 14-benzoylaconine-8-palmitate (5), 14-O-acetylsenbusine A (6), senbusine A (7) and 14-acetylneoline (8) were isolated from the whole
OBJECTIVE
Aconitum alkaloids mainly contain highly toxic aconitine (AC), mesaconitine (MA), and hypaconitine (HA) and less toxic benzoylaconine (BAC), benzoylmesaconine (BMA), benzoylhypaconine (BHA), aconine, mesaconine, and hypaconine. The efflux transporters including P-glycoprotein (P-gp),
