Binding studies with [3H]cis-methyldioxolane in different tissues. Under certain conditions [3H]cis-methyldioxolane labels preferentially but not exclusively agonist high affinity states of muscarinic M2 receptors.

Special conditions–tricine buffer containing Ca2+ and Mg2+, 22 degrees C (TCM)–allow to label a much higher proportion of muscarinic receptors by [3H]cis-methyldioxolane (CD) than hitherto described (Vickroy et al. 1984a). Taking the maximum number of binding sites, Bmax, of [3H]QNB as 100%, Bmax of [3H]CD amounts to 83% in the rat heart instead of the reported 17%, 33% in the cerebral cortex instead of 6%, 20% in hippocampus and 55% in pons/medulla. In the salivary glands specific binding was negligible. The affinities of a number of muscarinic agonists and antagonists to [3H]CD and [3H]QNB binding sites in different tissues of the rat are compared. Apparent affinities of agonists are much higher in the [3H]CD system, affinities of antagonists are slightly higher in the [3H]QNB system. In both assay systems receptors of heart and pons/medulla membranes seem to have similar drug specificity. They differ somewhat from those in the cortex. Receptors in the salivary glands, however, seem to be completely different from those in the other three tissues. In the heart [3H]CD binding can be abolished almost completely by GppNHp. In the cortex about half of the [3H]CD binding is susceptible to GppNHp. The reduction of binding in the cortex is due to a change in Bmax and not in the dissociation constant KD. Competition of unlabelled pirenzepine with [3H]CD: In heart and pons/medulla only low affinity sites for pirenzepine (M2-receptors) are labelled by [3H]CD.(ABSTRACT TRUNCATED AT 250 WORDS)

Directed synthesis of noncentrosymmetric molybdates using composition space analysis

A systematic investigation of the factors governing the reaction product composition, hydrogen bonding, and symmetry was conducted in the MoO 3/3-aminoquinuclidine/H2O system. Composition space analysis was performed through 36 individual reactions under mild hydrothermal conditions using racemic 3-aminoquinuclidine. Single crystals of three new compounds, [C7H16N2][Mo 3O10]¡¤H2O, [C7H 16N2]2[Mo8O26] ¡¤H2O, and [C7H16N2] 2[Mo8O26]¡¤4H2O, were grown. The relative phase stabilities for these products are dependent upon the reactant mole fractions in the initial reaction gel. This phase stability information was used to direct the synthesis of two new noncentrosymmetric compounds, using either (S)-(-)-3-aminoquinuclidine dihydrochloride or (R)-(+)-3-aminoquinuclidine dihydrochloride. [(R)-C7H 16N2]2-[Mo8O26] and [(S)-C7H16N2]2[Mo8O 26] both crystallize in the noncentrosymmetric space group P2 1 (No. 4), which has the polar crystal class 2 (C2). The second-harmonic generation activities were measured on sieved powders. The structure-directing properties of the molybdate components in each compound were determined using bond valence sums. The structures of all five compounds were determined using single-crystal X-ray diffraction.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 123536-14-1, you can also check out more blogs aboutReference of 123536-14-1

Pharmacological profile of zacopride and new quaternarized fluorobenzamide analogues on mammalian alpha7 nicotinic acetylcholine receptor

Abstract From quaternarization of quinuclidine enantiomers of 2-fluoro benzamide LMA10203 in dichloromethane, the corresponding N-chloromethyl derivatives LMA10227 and LMA10228 were obtained. Here, we compared the agonist action of known zacopride and its 2-fluoro benzamide analogues, LMA10203, LMA10227 and LMA10228 against mammalian homomeric alpha7 nicotinic acetylcholine receptor expressed in Xenopus oocytes. We found that LMA10203 was a partial agonist of alpha7 receptor with a pEC50 value of 4.25 ¡À 0.06 muM whereas LMA10227 and LMA10228 were poorly active on alpha7 homomeric nicotinic receptor. LMA10227 and LMA10228 were identified as antagonists of acetylcholine-induced currents with IC50 values of 28.4 muM and 39.3 muM whereas LMA10203 and zacopride possessed IC50 values of 8.07 muM and 7.04 muM, respectively. Moreover, despite their IC50 values, LMA10227 was the most potent inhibitor of nicotine-induced current amplitudes (65.7 ¡À 2.1% inhibition). LMA10203 and LMA10228 had the same inhibitory effects (26.5 ¡À 7.5% and 33.2 ¡À 4.1%, respectively), whereas zacopride had no significant inhibitory effect (4.37 ¡À 4%) on nicotine-induced responses. Our results revealed different pharmacological properties between the four compounds on acetylcholine and nicotine currents. The mode of action of benzamide compounds may need to be reinterpreted with respect to the potential role of alpha7 receptor.
