The sole thing that separates deserpidine from reserpine, a strong ganglionic blocker, is the lack of a methoxy group at C-11. Treatments for psychosis and hypertension include deserpine. Deserpine may also be helpful as a controlling medication for additional cardiac conditions [1][2].

ln Vivo |
A sensitive and rapid liquid chromatography/tandem mass spectrometric (LC/MS/MS) method was developed and validated for the determination of deserpidine in human plasma. The plasma samples were prepared using liquid-liquid extraction (LLE) with ethyl ether-dichloromethane (3:2, v/v). Chromatographic separation was accomplished on an Ultimate XB-C18 column. The mobile phase consisted of methanol-5mM ammonium acetate-formic acid (72:28:0.036, v/v/v). Detection of deserpidine and the internal standard tropisetron was achieved by tandem mass spectrometry with an electrospray ionization interface in positive ion mode. The lower limit of quantification was 4.0pg/ml. The linear range of the method was from 4.0 to 2000pg/ml. The intra- and inter-day precisions were lower than 14.7% in terms of relative standard deviation (RSD), and the accuracy was within +/-8.7% in terms of relative error (RE). This validated method was successfully applied for the evaluation of pharmacokinetics of deserpidine after a single oral administration dose of 0.25mg deserpidine to 22 healthy volunteers [2].

Enzyme Assay |
The Rauwolfia alkaloids reserpine (1) and deserpidine (2), two alkaloids from Rauwolfia species, have been widely used for their antihypertensive action. Deserpidine (2) is a compound with limited availability from natural sources, and its synthesis from 1 in six steps (41% overall yield) is reported here [1].

Additional Infomation |
Deserpidine is an alkaloid ester, a methyl ester, a benzoate ester, an organic heteropentacyclic compound and a yohimban alkaloid. It derives from a hydride of a yohimban.
Deserpidine is an ester alkaloid drug isolated from Rauwolfia canescens (family Apocynaceae) with antipsychotic and antihypertensive properties that has been used for the control of high blood pressure and for the relief of psychotic behavior. Deserpidine is a Catecholamine-depleting Sympatholytic. The physiologic effect of deserpidine is by means of Decreased Sympathetic Activity. Deserpidine has been reported in Aspergillus malignus, Rauvolfia serpentina, and other organisms with data available. Deserpidine is an ester alkaloid derived from Rauwolfia canescens with antihypertensive activity. Deserpidine is a competitive inhibitor of the angiotensin converting enzyme (ACE). By competing with angiotensin I for ACE, deserpidine blocks the conversion of angiotensin I to angiotensin II, which is a potent vasoconstrictor. Reduced level of serum angiotensin II causes a decrease in blood pressure. Deserpidine also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex. See also: Deserpidine; methyclothiazide (component of); Deserpidine; hydrochlorothiazide (component of). Drug Indication For the treatment of hypertension. Mechanism of Action Deserpidine's mechanism of action is through inhibition of the ATP/Mg2+ pump responsible for the sequestering of neurotransmitters into storage vesicles located in the presynaptic neuron. The neurotransmitters that are not sequestered in the storage vesicle are readily metabolized by monoamine oxidase (MAO) causing a reduction in catecholamines. Pharmacodynamics Deserpidine, an alkaloid of Rauwolfia canescens, is used as an antihypertensive. Rauwolfia alkaloids work by controlling nerve impulses along certain nerve pathways. As a result, they act on the heart and blood vessels to lower blood pressure. |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.32 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.32 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
