| PROADIFEN HYDROCHLORIDE Usage And Synthesis |
| Description | SKF 525A is a widely used, nonspecific cytochrome P (CYP)450 inhibitor that demonstrates 100% inhibition of the various CYP450 isoforms at 1-100 μM. It therefore potentiates the effects of many different drugs by inhibiting their metabolism (IC50 values in the μM range when tested using human liver microsomes). SKF 525A inhibits CYP450-dependent arachidonic acid conversion to active EET metabolites, antagonizing the recovery of functional calcium pools. It also acts as a noncompetitive inhibitor of acetylcholine nicotinic receptors (IC50 = 19 μM in mouse skeletal muscle). |
| Chemical Properties | Off-White Crystalline Solid |
| Uses | anti-infective |
| Uses | An inhibitor of NOS1, AChR, cytochrome P-450, and KIR6.1. |
| Uses | Cytochrome P-459 inhibitor; blocks glibenclamide-sensitive K+ channels; inhibits neuronal nitric oxide synthetase; stimulates endothelial cell prostacyclin while inhibiting platelet thromboxane synthesis |
| Uses | Proadifen hydrochloride is an inhibitor of NOS1, AChR, cytochrome P-450, and KIR6. Proadifen hydrochloride bind to the protein moiety of P-450, also reduced the hypoxic response. of Proadifen hydrochloride have good antiarrhythmic effects. SKF-525A substantially reduced the depletion of cardiac norepinephrine. |
| Safety Profile | Poison by intraperitoneal, subcutaneous, and intravenous routes. Moderately toxic by ingestion. Experimental reproductive effects. When heated to decomposition it emits very toxic fumes of NOx and HCl. |
| in vitro | previous study found that when incubated with human liver microsomes, skf525a could undergo cyp-dependent oxidative n-deethylation to its secondary amine metabolite skf8742. in addition, skf525a and its metabolite and primary amine analog all inhibited cyp2b6-, cyp2c9-, cyp2c19-, cyp2d6-, as well as cyp3a-selective reactions to various degrees but had little effect on cyp1a2, cyp2a6, and cyp2e1 reactions [1]. |
| in vivo | animal study found that skf 525a at 1.5-9 mg/kg could reduce or abolish the hypertensive effect of mcn-a-343, dmpp and nicotine, but could neither noticeably affect the hypertensive effect of tyramine, adrenaline and noradrenaline, nor the hypotensive effect of acetylcholine and orciprenaline. thus, skf 525a was able to block the rat sympathetic ganglia and the adrenal medulla and such blockade was non-specific. moreover, the blockade might result from the stabilizing effect of skf 525a on postsynaptic membranes of the sympathetic ganglia and the adrenal medulla [2]. |
