《Structure-activity relations of arecaidine derivatives on the guinea pig isolated atria》 was published in European Journal of Pharmacology in 1967. These research results belong to Christiansen, Anneliese; Lullmann, Heinz; Mutschler, Ernst. Application of 1690-72-8 The article mentions the following:

The influence of arecaidine esters, arecaidine methiodide esters, dihydroarecaidine esters, and dihydroarecaidine methiodide esters was tested on the amplitude of contraction of elec. stimulated isolated atria from the guinea pig. The amplitude of contraction was reduced by all arecaidine esters. This effect was abolished by atropine. Arecaidine Et ester possessed the highest activity and arecaidine iso-Pr ester was the least active. Like arecaidine Me ester, arecaidine methiodide Me ester showed muscarine-like properties. Quaternary esters with a longer chain showed nicotine-like action or acted as inhibitors. Dihydroarecaidine esters and dihydroarecaidine methiodide esters were antagonists; only dihydroarecaidine Me ester and dihydroarecaidine methiodide Me ester showed muscarine-like action. The experimental process involved the reaction of Methyl 1-methylpiperidine-3-carboxylate(cas: 1690-72-8Application of 1690-72-8)

《The action of tertiary and quaternary arecaidine and dihydroarecaidine esters on the guinea pig isolated ileum》 was published in British Journal of Pharmacology and Chemotherapy in 1966. These research results belong to Gloge, Holger; Luellmann, Heinz; Mutschler, Erich. Application of 1690-72-8 The article mentions the following:

A homologous series of tertiary and quaternary arecaidine esters (methyl to isobutyl), as well as the corresponding dihydrocompds., were investigated quant. on the isolated ileum of the guinea pig. The tertiary arecaidine esters are agonists. Highest activities (effective doses) are observed for the Et ester (E.D.50 = 1.5 × 10-4M) and for arecoline, the Me ester (E.D.50 = 5.8 × 10-8M). Esters with a longer side-chain show considerably lower activity. The intrinsic activities of arecaidine Et ester, arecoline, and dimethylaminoethyl acetate are higher than that of acetylcholine. Hydrogenation of the double bond in the ring markedly reduces the affinity and intrinsic activity of the tertiary arecaidine esters. Hydrogenated esters with a longer side-chain act as inhibitors. Quaternization by means of iodomethylation exerts varying influences on the intrinsic activities of arecaidine esters. In the case of the Me ester the intrinsic activity is somewhat reduced whereas that of the Et ester considerably decreases upon iodomethylation, thus yielding a partial antagonist. Similar transformation of esters with a longer side-chain leads to a complete loss of intrinsic activity. The quaternized compounds thus obtained are inhibitors with atropine-like action. Iodoethylation and iodopropylation even abolish the intrinsic activities of esters with a short side-chain. Hydrogenation of the double bond in the ring of the quaternary compounds similarly diminishes the activity as observed for the tertiary compounds For aliphatic N atoms, quaternization is essential in order to enable a reaction with the acetylcholine receptors of the muscarine type. In the case of ring N atoms, the tertiary protonated form is necessary for obtaining a high intrinsic activity upon combination with the receptor mol. In arecaidine esters, quaternization of the ring N atom reduces or even destroys intrinsic activity, in proportion to the length of the ester side-chain.

Aims/Introduction: To detect serum adipsin levels in individuals with different glucose tolerance, and investigate the relationship between adipsisn and the first phase of insulin secretion. Materials and Methods: A total of 56 patients with newly diagnosed type 2 diabetes mellitus, 36 patients with impaired glucose tolerance (IGT) and 45 individuals with normal glucose tolerance were enrolled. Intravenous glucose tolerance tests were carried out to evaluate pancreatic beta-cell function. The serum levels of adipsin, interleukin-1beta and high-sensitivity C-reactive protein were assayed. Results: Serum adipsin levels were significantly lower in the type 2 diabetes mellitus and the IGT patients than those in the normal glucose tolerance group (P < 0.05). The acute insulin response and area under the curve showed a progressive decrease in the normal glucose tolerance and IGT groups, and decreased to the lowest levels in the type 2 diabetes mellitus group (P < 0.05). Adipsin was found to be negatively correlated with waist-to-hip ratio, free fatty acid, fasting plasma glucose, 2-h postprandial plasma glucose, glycated hemoglobin, homeostasis model assessment of insulin resistance, interleukin-1beta and high-sensitivity C-reactive protein (P < 0.05 or P < 0.001), and positively correlated with homeostasis model assessment of beta-cell function, high-density lipoprotein cholesterol, the area under the curve of the first phase insulin secretion and acute insulin response (P < 0.05 or P < 0.001). Stepwise multiple regression analysis showed that homeostasis model assessment for beta-cell function and acute insulin response were independently related to adipsin (P < 0.05). Conclusions: Serum adipsin levels were lower in type 2 diabetes mellitus and IGT patients, and correlated with the first phase of insulin secretion. Adipsin might be involved in the pathology of type 2 diabetes mellitus. I hope this article can help some friends in scientific research.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, HPLC of Formula: C8H15NO2, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1690-72-8, Name is Methyl 1-methylpiperidine-3-carboxylate, molecular formula is C8H15NO2. In a Article, authors is Mendivil, Carlos O.，once mentioned of 1690-72-8

Objectives: Our current understanding of hormone regulation in lung parenchyma is quite limited. We aimed to quantify a diverse array of biologically relevant protein mediators in alveolar lining fluid (ALF), compared to serum concentrations, and explore factors associated with protein compartmentalization on either side of the air-blood barrier. Research Design and Methods: Participants were 24 healthy adult non-smoker volunteers without respiratory symptoms or significant medical conditions, with normal lung exams and office spirometry. Cell-free bronchoalveolar lavage fluid and serum were analyzed for 24 proteins (including enteric and metabolic hormones, apolipoproteins, adipokines, and cytokines) using a highly sensitive multiplex ELISA. Measurements were normalized to ALF concentrations. The ALF: serum concentration ratios were examined in relation to measures of protein size, hydrophobicity, charge, and to participant clinical and spirometric values. Results: ALF measurements from 24 individuals detected 19 proteins, including adiponectin, adipsin, apoA-I, apoA-II, apoB, apoC-II, apoC-III, apoE, C-reactive protein, ghrelin, glucose-dependent insulinotropic peptide (GIP), glucagon-like peptide-1 (GLP-1), glucagon, insulin, leptin, monocyte chemoattractant protein-1, plasminogen activator inhibitor-1, resistin, and visfatin. C-peptide and serpin E1 were not detected in ALF for any individual, and IL-6, IL-10, and TNF-alpha were not detected in either ALF or serum for any individual. In general, ALF levels were similar or lower in concentration for most proteins compared to serum. However, ghrelin, resistin, insulin, visfatin and GLP-1 had ALF concentrations significantly higher compared to serum. Importantly, elevated ALF:serum ratios of ghrelin, visfatin and resistin correlated with protein net charge and isoelectric point, but not with molecular weight or hydrophobicity. Conclusions: Biologically relevant enteric and metabolic hormones, apolipoproteins, adipokines, and cytokines can be detected in the ALF of healthy individuals. For the proteins measured, charge may influence trafficking and compartmentalization to the alveolar airspace more than molecular weight or hydrophobicity. These data may have implications for homeostasis and drug delivery to the lung.

Background: Tuberculous meningitis (TBM) is the most severe form of tuberculosis and results in high morbidity and mortality in children. Diagnostic delay contributes to the poor outcome. There is an urgent need for new tools for the rapid diagnosis of TBM, especially in children. Methods: We collected serum samples from children in whom TBM was suspected at a tertiary hospital in Cape Town, South Africa. Children were subsequently classified as having TBM or no TBM using a published uniform research case-definition. Using a multiplex cytokine array platform, we investigated the concentrations of serum biomarkers comprising biomarkers that were previously found to be of value in the diagnosis of adult pulmonary TB (CRP, SAA, CFH, IFN-gamma, IP-10, Apo-AI, and transthyretin) plus other potentially useful host biomarkers as diagnostic candidates for TBM. Findings: Out of 47 children included in the study, 23 (48.9%) had a final diagnosis of TBM and six were HIV infected. A modified version of the adult 7-marker biosignature in which transthyretin was replaced by NCAM1, diagnosed TBM in children with AUC of 0.80 (95% CI, 0.67?0.92), sensitivity of 73.9% (95% CI, 51.6?89.8%) and specificity of 66.7% (95% CI, 44.7?84.4%), with the other six proteins in the signature (CRP, IFN-gamma, IP-10, CFH, Apo-A1, and SAA) only achieving and AUC of 0.75 (95%CI, 0.61?0.90) when used in combination. A new childhood TBM specific 3-marker biosignature (adipsin, Abeta42, and IL-10) showed potential in the diagnosis of TBM, with AUC of 0.84 (95% CI, 0.73?0.96), sensitivity of 82.6% (95 CI, 61.2?95.0%) and specificity of 75.0% (95% CI, 53.3?90.2%) after leave-one-out cross validation. Conclusion: A previously described adult 7-marker serum protein biosignature showed potential in the diagnosis of TBM in children. However, a smaller childhood TBM-specific 3-marker signature demonstrated improved performance characteristics. Our data indicates that blood-based biomarkers may be useful in the diagnosis of childhood TBM and requires further validation in larger cohort studies.
