NSL O5736 Ring-substituted amphetamine interactions with neurotransmitter receptor binding sites in human cortex Pamela A. Pierce and Stephen J. Peroutka Deparmentsof Neurologyand Pharmacology, Stanford University Medical Center, StanJbrd,CA 94305 (U.S.A.) (Received 31 May 1988; Revised version received 11 August 1988; Accepted 12 August 1988) Key words.' Ring-substituted amphetamine; (_+)-3,4-Methylenedioxyamphetamine; ( +_)-3,4-Methylene- dioxyethamphetamine; (_+)-3,4-Methylenedioxymethamphetamine; Ecstasy; 4-Bromo-2,5- dimethoxyphenylisopropylamine binding site; Human cortical receptor The binding affinities of 3 ring-substituted amphetamine compounds were determined at 9 neurotrans- mitter binding sites in human cortex. (_+)-3,4-Methylenedioxyamphetamine (MDAk (_+)-3,4-methylene- dioxyethamphetamine (MDE), and (_+)-3,4-methylenedioxymethamphetamine (MDMA or 'Ecstasy') all display highest affinity (approximately 1 /tM) for the recently identified 'DOB binding site' labeled by ['TBr]R(-)4-bromo-2,5-dimethoxyphenylisopropylamine ([77Br]R(-)DOB). MDA displays moderate affinity (4-5/iM) for the 5-hydroxytryptaminetA (5-HTr^), 5-HT_D,and =,-adrenergic sites in human cor- tex. MDE and MDMA display lower affinity or are inactive at all other sites tested in the present study. These observations are discussed in relation to the novel psychoactive effects of the ring-substituted amphetamines. A series of ring-substituted amphetamine derivatives exist which are structurally related to both amphetamines and hallucinogens. However, drugs such as (+)-3,4- methylenedioxyamphetamine (MDA), (_+)-3,4-methylenedioxyethamphetamine (MDE), and (+)-3,4-methylenedioxymethamphetamine (MDMA or 'Ecstasy') ap- pear to produce unique psychoactive effects which are distinct from the effects of both amphetamines and hallucinogens [13, 15].

  • “Rauwolscine/ Alfa Yohimbine”
    “Rauwolscine/ Alfa Yohimbine” Rauwolscine / Alfa Yohimbine – Natural and Safe Alternative for FAT BURNING Rauwolscine or Alfa–Yohimbine is an indole alkaloid with stimulant, aphrodisiac and local anaesthetic effects found naturally in plants of the genus Rauwolfia and Pausinystalia, along with several other active alkaloids including Yohimbine. Rauwolscine is a stereoisomer of Yohimbine, that is it is chemically identical, but differs in its 3 dimensional orientation. There are a total of 3 stereoisomers of Yohimbine, the other two are corynanthine and 3-epi-alpha-yohimbine. How it works – science behind this natural supplement Fat-Burning Potential Rauwolscine, or {3H}Rauwolscine, is a potent and selective antagonist of alpha-2 adrenergic receptors. This is the same mechanism by which yohimbine acts by blocking the pre- and post-synaptic alpha-2 adrenoceptors, this prevents the release of Norepinephrine from cells. Norepinepherine stimulates both the alpha and beta receptors in a cell. Stimulation of the beta adrenoceptors causes the breakdown of fat, whilst stimulating the alpha-2 adrenoceptors prevents this breakdown of fats.Alfa Yohimbine (Rauwolscine) blocks the alpha feedback mechanism, thus increasing norepinephrine. Additionally in blocking the alpha-2 receptor it blocks the storage of new fat. Serotonergic Effects Its works in a similar fashion like yohimbine, rauwolscine is an agonist of 5-HT1a/b receptors and induces serotonin-like effects.Whereas yohimbine has more affinity for the receptor, rauwolscine has a lower IC50 value (meaning it can saturate more receptors at the same dose) and can be seen as slightly more potent in serotonergic activity. Rauwolscine, an antagonist radioligand for the cloned human 5- hydroxytryptamine2b (5-HT2B) receptor.

  • Novel Histamine H3 Receptor Antagonists: Affinities in an H3 Receptor Binding Assay and Potencies in Two Functional H3 Receptor Models
    Br. J. Pharmacol. (1994), 112, 1043-1048 '." Macmillan Press Ltd, 1994 Novel histamine H3 receptor antagonists: affinities in an H3 receptor binding assay and potencies in two functional H3 receptor models 'E. Schlicker, M. Kathmann, *S. Reidemeister, *H. Stark & *W.

The novel compounds differ from histamine in that the aminoethyl side chain is replaced by a propyl or butyl chain linked to a polar group (amide, thioamide, ester, guanidine, guanidine ester or urea) which, in turn, is connected to a hexocyclic ring or to an alicyclic ring containing an alkyl residue. 2 The specific binding of [3H]-N-methylhistamine to rat brain cortex membranes was monophasically displaced by each of the ten compounds at pKi values ranging from 7.56 to 8.68. 3 Inhibition by histamine of the electrically evoked tritium overflow from mouse brain cortex slices preincubated with [3H]-noradrenaline was antagonized by the ten compounds and the concentration- response curve was shifted to the right with apparent pA2 values ranging from 7.07 to 9.20. 4 The electrically induced contraction in guinea-pig ileum strips (which was abolished by atropine) was inhibited by the H3 receptor agonists R-(-)-a-methylhistamine (pECm 7.76), N-methylhistamine (7.90) and imetit (8.18).

All compounds used in heterocyclic skeletons occurring in a number of bioactive the synthesis were of reagent grade and used without further molecules for a variety of biological targets1 and form, in purification, and the solvents were freshly distilled by using particular, the tetracyclic antidepressants such as mianserin standard purification methods.
