In homogeneous catalysis, catalysts are in the same phase as the reactants. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.2179-57-9, Name is Diallyldisulfide, SMILES is C=CCSSCC=C, belongs to quinuclidine compound. In a document, author is VanHooft, JA, introduce the new discover, SDS of cas: 2179-57-9.
RS-056812-198: Partial agonist on native and antagonist on cloned 5-HT3 receptors
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.
