The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: cis-4-Aminocyclohexane carboxylic acid(SMILESS: N[C@H]1CC[C@H](CC1)C(O)=O,cas:3685-23-2) is researched.Category: chiral-oxygen-ligands. The article 《Characterization of an inhibitory receptor in rat hippocampus. A microiontophoretic study using conformationally restricted amino acid analogs》 in relation to this compound, is published in British Journal of Pharmacology. Let’s take a look at the latest research on this compound (cas:3685-23-2).

The inhibitory potencies of GABA [56-12-2], β-alanine [107-95-9], and glycine [56-40-6] in rat hippocampal pyramidal cells were determined and compared with those of substituted aminocyclopentane and aminocyclohexane carboxylic acids (ACPC and ACHC resp.). The order of effectiveness of the small aliphatic amino acids was GABA > β-alanine > glycine. GABA-induced inhibition was inhibited by iontophoresis of bicuculline or picrotoxin but not strychnine-HCl. The inhibitory abilities of the substituted ACPC and ACHC derivatives was a direct function of the separation of NH2 and CO2H groups in both series of cyclic amino acids. The most potent inhibition was observed when the spatial separation was similar to that of the extended GABA mol. (4.74 Å). Inhibition by (±)-cis-3-aminocyclopentanecarboxylic acid was blocked by simultaneous application of bicuculline or picrotoxin, but not by strychnine-HCl. The physiol. active conformation of GABA is probably the fully extended mol. and one dimension of the postsynaptic receptor site is probably within the range 4.2-4.8 Å.

Formula: C7H13NO2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about Synthesis of di- and tripeptides containing 4-aminocyclohexanecarboxylic acid. Author is Chen, Wen-Yih; Olsen, Richard K..

Amino acid derivatives were coupled to cis- and trans-4-aminocyclohexanecarboxylic acid with diethylphosphoryl cyanide as coupling reagent. Treatment of trans-I (R = Me3CO2C, R1 = OH) with diethylphosphoryl cyanide, followed by condensation with L-valine Me ester gave trans I (R = Me3CO2C, R1 = Val-OMe) (II). Deprotection and coupling of II with N-tert-butoxycarbonyl-L-alanine gave trans-I (R = Me3CO2C-Ala-, R1 = Val-OMe). Similar transformations were effected with cis-I (R = Me3CO2C, R1 = OH). Other coupling procedures investigated were the carbodiimide, p-nitrophenyl active ester, and sym. anhydride methods, which were less satisfactory for coupling to cyclohexane amino acids.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Microchemical Journal called Analysis of metabolites and metabolic mechanism in Bt transgenic and non-transgenic maize, Author is Zhang, Liyuan; Yu, Runzhong; Yu, Yingbo, which mentions a compound: 3685-23-2, SMILESS is N[C@H]1CC[C@H](CC1)C(O)=O, Molecular C7H13NO2, Safety of cis-4-Aminocyclohexane carboxylic acid.

The gas chromatog.-mass spectrometry was used to isolate and identify metabolites of non-transgenic and Bacillus thuringiensis transgenic maize. The non-targeted metabolomics technique was used to anal. the metabolic pathway and mechanism of two kinds of maize. The methanol was used as extractant and the N,O-bis(trimethylsilyl) trifluoroacetamide was used as derivatization reagent. 38 kinds of metabolites were isolated and identified from non-transgenic maize, and 61 kinds of metabolites were isolated and identified in Bacillus thuringiensis transgenic maize. The specific metabolites between non-transgenic and Bacillus thuringiensis transgenic maize were analyzed. The metabolic pathway of specific metabolites was analyzed by KEGG annotation. The metabolic mechanism of non-transgenic maize and Bacillus thuringiensis transgenic maize was explored. The result indicated there were more metabolites involved in metabolic pathways in Bacillus thuringiensis transgenic maize than in non-transgenic maize, and tricarboxylic acid cycle and energy metabolism pathways of Bacillus thuringiensis transgenic maize are found to be higher than that of non-transgenic maize. The metabolic pathway of Bacillus thuringiensis transgenic maize conforms to the biol. activity law.

Quality Control of 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 The uptake and radioautographical localization of (±)-[3H]cis-aminocyclohexanecarboxylic acid by the isolated frog retina. Author is Cunningham, Jo; Marshall, J.; Neal, M. J..

Uptake of aminocyclohexanecarboxylic acid (I) [39275-59-7] by frog retinas was temperature-sensitive and highly Na-dependent, and was inhibited by GABA [56-12-2], L-2,4-diaminobutyric acid (II) [1758-80-1], and β-alanine [107-95-9] with IC50 values of 0.32, 0.23, and 9.0 mM, resp. Radioautog. studies indicated that the sites of I-3H and GABA-3H uptake were identical, the compounds being accumulated almost exclusively in the horizontal cells. II-3H and β-alanine-3H were accumulated predominantly in the Mueller cells and photoreceptors, resp. Although II possesses affinity for the I (GABA) transport system in the horizontal cells, I and GABA apparently have no affinity for the (high affinity) II transport system in the Mueller cells.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Triazine-Cored Lanthanide-Based Metal-Organic Frameworks Featuring Unique Water Chains and Strong Characteristic Emissions, published in 2019, which mentions a compound: 3685-23-2, Name is cis-4-Aminocyclohexane carboxylic acid, Molecular C7H13NO2, Electric Literature of C7H13NO2.

A new triazine-cored tricarboxylic acid, N,N’,N”-1,3,5-triazine-2,4,6-triyltris(cis-4-aminocyclohexane-carboxylicacid)(H3L), was prepared by replacing the chlorine atoms of cyanuric chloride with cis-4-aminocyclohexane-carboxylic acid, which was used for the construction of a series of triazine-cored lanthanide-based metal-organic frameworks (MOFs). All these MOFs were structurally authenticated, revealing that they are isostructural and exist as two-dimensional (2D) coordination networks with the general formula [Ln(L)(H2O)2]·5.5 H2O (Ln = 1·Gd, 2·Tb, 3·Eu). A unique one-dimensional water chain, composed of primary tetrameric cyclic rings and dodecameric cyclic rings, was found entrapped in the lattice. Moreover, all these compounds display bright characteristic photoluminescence. Particularly, for 1, apart from the strong blue emission peak (Φf = 20.6 %) corresponding to the intraligand transition under near-UV excitation, the characteristic emissions of Gd3+ cation (Φf = 5.0 %) were unexpectedly observed upon excitation at 273 nm.

Author is Ivica, Josko; Gauthier, Jeannette; Power, Patricia; Lamy, Andre; Potter, Murray.

Tranexamic acid is a drug used during open cardiac surgery to prevent blood loss. The blood levels of 10-100μg/mL are reported to be in the therapeutic range and higher levels are linked to increased incidence of adverse effects. The aim of this study was to optimize and validate an LC-MS/MS method for serum tranexamic acid and measure its levels in patients from the DEPOSITION Pilot trial in order to prove the concept that topical administration will yield lower serum concentration The method development was carried out in several steps including sample preparation, and optimization of chromatog. and tandem mass spectrometry parameters. Method validation including day-to-day precision with 4 QC levels, limit of detection, sample stability, carryover, and concentration-signal linearity was carried out. Ninety patient samples were analyzed using the validated method. Fast and efficient LC-MS/MS method for anal. of tranexamic acid in serum was developed. The run time was 7 min with the total time of one hour including the sample preparation The method precision was acceptable (%CV = 10.5-12.6%) with no sample carryover observed The matrix effect on the anal. sensitivity was negligible and the lower limit of detection was 0.5μg/mL. The difference in the mean adjusted concentrations between topical (45 patients) and i.v. (45 patients) groups was statistically significant (0.1154μg/mL/kg vs. 0.2542μg/mL/kg, p < 0.0001). Rapid and simple LC-MS/MS method for anal. of tranexamic acid was optimized and validated. The laboratory has played a crucial role in proving the concept that topical administration yields significantly lower systemic levels of tranexamic acid, and thus decreases the risk of adverse outcomes in patients undergoing open cardiac surgery. From this literature《Analysis of serum tranexamic acid in patients undergoing open heart surgery》,we know some information about this compound(3685-23-2)Recommanded Product: cis-4-Aminocyclohexane carboxylic acid, but this is not all information, there are many literatures related to this compound(3685-23-2).

Formula: C7H13NO2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about Knoevenagel Reaction. Kinetic study of the reaction of (+)-3-methyl-cyclohexanone with malononitrile. Author is Prout, Franklin S.; Beaucaire, Victor D.; Dyrkacz, Gary R.; Koppes, William M.; Kuznicki, Robert E.; Marlewski, Theordore A.; Pienkowski, James J.; Puda, Jacqueline M..

The condensation of malononitrile with (+)-3-methylcyclohexanone produced an 80-85% yield of (-)-3-methylcyclohexylidenemalononitrile. The reaction, followed polarimetrically in aqueous alc., is kinetically second order and efficiently catalyzed by weak bases (ω-amino acids, cyclic amino acids, NH4OAc) furnishing solutions having an apparent pH 7.5-8.0. With β-alanine as catalyst, the Ea was 7.6 kcal/mole compared to 11 kcal/mole uncatalyzed. Stronger bases (Barbital, NaOAc, LOAc, KF, piperidine) effect more rapid condensation but poorer kinetics because of telomerization of malononitrile at the higher pHs.
