[3H]RS79948-197 binding to human, rat, guinea pig and pig alpha2A-, alpha2B- and alpha2C-adrenoceptors. Comparison with MK912, RX821002, rauwolscine and yohimbine.[Pubmed:9551719]
Eur J Pharmacol. 1998 Feb 5;343(1):93-101.
The Kd values of the recently introduced radioligand [3H]RS79948-197 ((8a R,12aS,13a-S)-5,8,8a,9,10,11,12,12a,13,13a-decahydro-3-metho xy-12-(ethylsulphonyl)-6H-isoquino[2,1-g][1,6]naphthyridine) were determined for the recombinant human and rat alpha2A-, alpha2B- and alpha2C- as well as guinea pig alpha2B- and alpha2c-adrenoceptors expressed in COS (CV-1 Origin, SV40) cells. In addition, the Kd values were also determined for [3H]RS79948-197 for the guinea pig spleen alpha2A-adrenoceptor and for pig alpha2A-, alpha2B- and alpha2C-adrenoceptors in membranes obtained from kidney and striatum. Available radioligands for alpha2-adrenoceptors, besides [3H]RS79948-197 are the tritiated forms of MK912 ((2S,12bS)1',3'-dimethylspiro(1,3,4,5',6,6',7,12b-octa hydro-2H-benzo[b]furo[2,3-a]quinazoline)-2,4'-pyrimidin-2'-one), RX821002 (2-methoxy-idazoxan), rauwolscine and yohimbine. In the present article the binding constants of all these substances for the alpha2A-, alpha2B- and alpha2C-adrenoceptor subtypes in human, pig, rat and guinea pig are reviewed. In all species tested MK912 was alpha2C-selective, RX821002 showed a minor alpha2A-selectivity, whereas [3H]RS79948-197 was non-selective among the alpha2-adrenoceptor subtypes, showing high affinity for all three subtypes. Rauwolscine and yohimbine showed relatively low affinities for nmost of the alpha2-adrenoceptor subtypes investigated, the exception being rauwolscine having high affinity for the human and porcine alpha2C-adrenoceptors.
Partial agonist properties of rauwolscine and yohimbine for the inhibition of adenylyl cyclase by recombinant human 5-HT1A receptors.[Pubmed:8517875]
Biochem Pharmacol. 1993 Jun 9;45(11):2337-41.
Previous studies by another group have suggested that the alpha 2-adrenergic receptor antagonist rauwolscine may function as an agonist at the serotonin1A (5-HT1A) receptor expressed in human brain. To directly test that hypothesis, we transfected the human 5-HT1A receptor cDNA into CHO cells and examined the ability of rauwolscine and its isomer, yohimbine, to inhibit ligand binding of [3H]-(+/-)-8-hydroxy-2-(di-n-propylamino)tetralin ([3H]8-OH-DPAT) and the activity of adenylyl cyclase in membranes derived from a single transformant that stably expresses approximately 225 fmol of 5-HT1A receptor/mg of membrane protein. Both ligands competitively antagonized the binding of [3H]8-OH-DPAT (Ki = 158 +/- 69 nM for rauwolscine and 690 +/- 223 nM for yohimbine), yielding shallow displacement curves consistent with agonist activity (Hill values = 0.69 +/- 0.2 for rauwolscine and 0.63 +/- 0.06 for yohimbine). Both ligands also inhibited forskolin-stimulated adenylyl cyclase activity in membranes derived from transfected (but not nontransfected) cells. For rauwolscine, the IC50 was 1.5 +/- 0.2 microM, and for yohimbine 4.6 +/- 1.0 microM, with activity ratios of 0.70 and 0.59, respectively, when compared to the full agonist serotonin. These studies demonstrated that rauwolscine and yohimbine are partial agonists for the human 5-HT1A receptor.
