Name: cis-4-Aminocyclohexane carboxylic acid. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about Synthesis and opioid activity of dynorphin A-(1-13)NH2 analogs containing cis- and trans-4-aminocyclohexanecarboxylic acid. Author is Snyder, Kristin R.; Murray, Thomas F.; DeLander, Gary E.; Aldrich, Jane V..
4-Aminocyclohexanecarboxylic acid (I) was synthesized by catalytic hydrogenation of p-aminobenzoic acid, and the cis and trans isomers were separated by fractional recrystallization Analogs of dynorphin A(1-13)amide containing cis- and trans-I were prepared by solid-phase peptide synthesis using the 9-fluorenylmethoxycarbonyl (Fmoc) chem. protocol. Results from radioligand binding assays indicated that the peptides have modest affinity for κ opioid receptors and modest κ-receptor selectivity. These analogs containing cis- and trans-I are the first reported dynorphin A analogs constrained in the message sequence that are selective for κ receptors. The analog containing cis-I showed very weak opioid activity in the guinea pig ileum.
Different reactions of this compound(cis-4-Aminocyclohexane carboxylic acid)Name: cis-4-Aminocyclohexane carboxylic acid require different conditions, so the reaction conditions are very important.
