reserpine

Reserpine (Serpalan) is an alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.

L-5-Hydroxytryptophan (L-5-HTP), the immediate precursor in the biosynthesis of SEROTONIN from tryptophan, is used as an antiepileptic and antidepressant.

Deserpidine (Harmonyl) is only found in individuals that have used or taken this drug. It 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'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. Deserpidine is a competitive angiotensin converting enzyme (ACE) inhibitor. Deserpidine also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex.

Isopimaric acid is active against MDR and MRSA strains of S. aureus which are becoming increasingly resistant to antibiotics, the minimum inhibitory concentrations (MIC) are 32-64 microg/mL . Isopimaric acid is also possible that an antagonistic interacti
