Effects of (R)-N-(quinuclidin-3-yl)-2-(1-methyl-1H-indol-3-yl)-2-oxo-acetamide (RS-056812-198) on 5-HT3 receptors have been investigated in whole-cell voltage-clamped N1E-115 mouse neuroblastoma cells and on 5-HT3 receptors composed of either long (5-HT(3)R-A(L)) or short (5-HT(3)R-A(S)) subunits expressed in Xenopus laevis oocytes. In N1E-115 cells RS-056812-198 evokes small transient inward currents, which are completely and reversibly inhibited by the selective 5-HT3 receptor antagonist MDL 72222 and cross-desensitizes with the 5-hydroxytryptamine (5-HT)-evoked current. The concentration-effect curve of RS-056812-198 yields an EC(50) of 18 nM and a maximum amplitude of 15% of the maximum 5-HT-evoked current. In contrast to its effects on N1E-115 cells, RS-056812-198 does not evoke an ion current on cloned 5-HT3 receptors expressed in Xenopus oocytes, but acts as an antagonist. For 5-HT(3)R-A(L) receptors, the IC50 of RS-056812-198 is 0.4 nM. The results show that (1) RS-056812-198 is a high-affinity partial agonist on 5-HT3 receptors in N1E-115 cells, thus providing a valuable tool to study agonist-receptor interaction in more detail; (2) 5-HT3 receptors in N1E-115 cells differ from the homo-oligomeric 5-HT3 receptors expressed in Xenopus oocytes. Whether the difference is caused by differences in protein processing in the two preparations or by expression of additional, yet unidentified subunits in N1E-115 cells and consequent formation of hetero-oligomeric 5-HT3 receptors remains to be determined.

Name: Cyclohex-3-en-1-ylmethanol, New discoveries in chemical research and development in 2021. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 1679-51-2, Name is Cyclohex-3-en-1-ylmethanol, SMILES is OCC1CCC=CC1, belongs to quinuclidine compound. In a article, author is Johansson, G, introduce new discover of the category.

A series of 25 derivatives of the muscarinic antagonist 3-(2-furanyl)quinuclidin-2-ene (4) was synthesized and evaluated for muscarinic and antimuscarinic properties. Substitution at all three positions of the furan ring has been investigated. The affinities of the new compounds were determined by competition experiments in homogenates of cerebral cortex, heart, parotid gland, and urinary bladder from guinea pigs using (-)-[H-3]-3-quinuclidinyl benzilate as the radioligand, and the antimuscarinic potency was determined in a functional assay on isolated guinea pig urinary bladder using carbachol as the agonist. Several of the novel derivatives displayed high muscarinic affinities. Whereas the affinity of lead compound 4 for cortical muscarinic receptors is moderate (K-i 300 nM), it is much higher for the 6-methyl (49; K-i = 12 nM), 5-ethyl (52; K-i = 7.4 nM), 5-bromo (33; K-i = 6.4 nM), and 3-phenyl (49; K-i = 2.8 nM) substituted derivatives. The substituent-induced increases in affinity do not appear to be additive as a 5-bromo-3-phenyl (54), and a 5-methyl-3-phenyl (55) substitution pattern only slightly increases affinity (K-i = 1.55 and 2.39 nM, respectively). The conformational preferences of the 3-phenyl (49) and 5-phenyl (51) derivatives were studied by X-ray crystallography and molecular mechanics calculations. Because of the observed high affinity of 49, a series of 16 meta-and para-substituted analogues of 49 was synthesized and tested. derivative (68) exhibited more than 10-fold improvement in affinity as compared to 49. The structure-activity relationships of the new series are well described with QSAR and CoMFA models.

In a article, author is Gohlke, H, introduce new discover of the category.

Three-dimensional quantitative structure-activity relationship methods, the comparative molecular field analysis (CoMFA) and the comparative molecular similarity indices analysis (CoMSIA), were applied using a training set of 45 ligands of the (alpha4)(2)(beta2)(3) nicotinic acetylcholine receptor (nAChR). All compounds are related to (-)-epibatidine, (-)-cytisine, (+)-anatoxin-a, and (-)-ferruginine, and additionally, novel diazabicyclo[4.2.1]nonane- and quinuclidin-2-ene-based structures were included. Their biological data have been determined by utilizing the same experimental protocol. Statistically reliable models of good predictive power (CoMFA r(2) = 0.928, q(2) = 0.692, no. of components = 3; CoMSIA r(2) = 0.899, q(2) = 0.701, no. of components = 3) were achieved. The results obtained were graphically interpreted in terms of field contribution maps. Hence, physicochemical. determinants of binding, such as steric and electrostatic and, for the first time, hydrophobic, hydrogen bond donor, and hydrogen bond acceptor properties, were mapped back onto the molecular structures of a set of nAChR modulators. In particular, changes in the binding affinity of the modulators as a result of modifications in the aromatic ring systems could be rationalized by the steric, electrostatic, hydrophobic, and hydrogen bond acceptor properties. These results were used to guide the rational design of new nAChR ligands such as 48-52 and 54, which were subsequently synthesized for the first time and tested. Key steps of our synthetic approaches were successfully applied Stille and Suzuki cross-coupling reactions. Predictive r(2) values of 0.614 and 0.660 for CoMFA and CoMSIA, respectively, obtained for 22 in part previously unknown ligands for the (alpha4)(2)(beta2)(3) subtype, demonstrate the high quality of the 3D QSAR models.
