Fangchinoline

Radix Step Haniae Tetrandrae containing tetranin (Tet) and Fangchinoline, is traditionally used as an analgesic, anti-rheumatic drug and anti-hypertensive in China. In this study, we studied its effect on the proliferation of breast cancer cells and their possible mechanism of action in vitro. Treatment of the cells with Fangchinoline inhibited MDA-MB-231 proliferation significantly and concentration-dependent and time-dependent. In order to determine the mechanism underlying the anti-proliferative effects of Fangchinoline, we studied its effect on critical molecular events, one of which is known to regulate apoptotic mechanisms. Specifically, we have the possibility of Fangchinoline to induce apoptosis of breast cancer cells. Fangchinoline interucleosomal DNA-induced fragmentation, chromatin condensation, activation of caspases-3, -8 and (ADP-ribose) polymerase -9 and cleavage of poly and enhanced release of cytochrome c Mitochondrial. In addition Fangchinoline increased expression of the pro-apoptotic protein of B-cell lymphoma associated with X-2 (BAX) and decreased expression of B-cell anti-apoptotic lymphoma protein (Bcl-2). In addition, the anti-proliferative effect of Fangchinoline with reduced amounts was associated with phosphorylated Akt. Our results show that Fangchinoline can inhibit the proliferation of breast cancer cells by inducing apoptosis via the mitochondrial apoptotic pathway and the decrease of phosphorylated Akt. Thus Fangchinoline can be a new way, which can be potentially developed clinically to achieve human malignant tumors.

Lupanine price

Product: Lupanine

CAS: 550-90-3

Molecular formula: C15H24N2O

Description: Lupanin produces a quinolizidine alkaloid from plants of the genus Lupinus. It has been shown to be a Pseudomonas sp. With a conversion to 17 Hydroxylupanin as the first step. The enzyme is inhibited by the growth of the organism on induziert.Es of lupanine was partially purified by Rogozinski and cleaned later and is characterized by the etal.It hopper located in the periplasm of the organism and is a monomer protein Of Mr 72000 with a pyrrolo Chinon molecule and a covalent linkage coefficients related heme. It catalyses the dehydrogenation of lupanine with PQQ as an electron and the electrons are transferred to the heme, before being transmitted to an external acceptor.

What is Securinine alkaloids

There had been experiments to determine the site of action of securinine and related spasmodic Indolizidinen. All these compounds induced tonic induced in mice with CD50 values ​​of 11 to 87 mg / kg. The CD50 for bicuculline was at 8 mg / kg found. Equilibrium binding assays have shown that dihydrosecurinin securinin and [3H] GABA binding to rat brain membranes with an inhibitory IC of about 50 μM, which is about 7-fold less potent than Bicuculline. Allosecurinin Virosecurinin and have IC50 values ​​greater than 1 mM. Both dihydrosecurinin and securinin inhibited GABA-stimulated Benzodiazepinbindung in rat brain membranes, although they were a little weaker in this regard than bicuculline. Other binding assays have shown that securinin and its analogs are inactive as inhibitors of bicuculline insensitive to GABA binding, a benzodiazepine, and the cholinergic receptor beta-adrenergic binding Muskarinin. In addition, while thiocyanate apparent bicuculline cohesion increased by 10-fold, it had little effect on the securinin. Extracellular electrophysiological studies on neurons in the spinal cord of the cat showed that securinin dihydrosecurinin and the inhibitory effect of GABA blocked, without this affected the action of glycine. Allografts and Virosecurinin were significantly less active in this assay than GABA receptor antagonists. These results suggest that, as bicuculline and securinine dihydrosecurinin are selective antagonists of GABA recognition sites in central mammalian neurons.
