Synthesis and SAR of 2-aryloxy-4-alkoxy-pyridines as potent orally active corticotropin-releasing factor 1 receptor antagonists

A series of 2-aryloxy-4-alkoxy-pyridines (1) was identified as novel, selective, and orally active antagonists of the corticotropin-releasing factor 1 (CRF1) receptor. Among these, compound 2 (CP-316311) is a potent and selective CRF1 receptor antagonist with an IC50 value of 6.8 nM in receptor binding and demonstrates oral efficacy in central nervous system (CNS) in vivo models. The regiochemistry of compounds in this series was determined by an X-ray structural analysis. A method to control regioselectivity via pyridine-N-oxides was developed. The synthesis of compounds in series 1 (Figure 1) and [3H]-2 as well as the structure-activity relationship (SAR) are discussed. The in vitro, ex vivo, and in vivo properties of representative compounds are described herein. Compound 2 was advanced to phase II depression trials to test the hypothesis that CRF1 antagonists could be used clinically as antidepressant drugs.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 453-20-3 is helpful to your research. Synthetic Route of 453-20-3

Domino Two-Step Oxidation of beta-Alkoxy Alcohols to Hemiacetal Esters: Linking a Stoichiometric Step to an Organocatalytic Step with a Common Organic Oxidant

Primary and secondary beta-alkoxy alcohols can be cleanly and efficiently oxidized into hemiacetal esters in a cascade two-step process. mCPBA serves both as a stoichiometric oxidant in the first TEMPO-catalyzed step, converting alcohols to aldehydes/ketones, and as a reagent in the second Baeyer?Villiger stoichiometric oxidation, transforming the aldehydes/ketones into hemiacetal esters. The use of an oxidant common to both steps enables the domino reaction to proceed under a single experimental setting. Longer oxidative cascade sequences are possible when this new methodology is applied to suitable substrates.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C4H8O2, you can also check out more blogs about453-20-3

Metabolomics and the diagnosis of human diseases-a guide to the markers and pathophysiological pathways affected

This review was designed as a handbook of metabolomic markers of high significance for a wide range of human diseases. This is the first report to collate results from recent studies in a format that allows ready identification of key metabolites by cross-comparisons of results from one disease to another. All the data presented in this work were obtained by previous research carried out exclusively during clinical trials in humans. Also, discussion of the pathophysiological pathways linked to the markers described is provided. The clinical assays focused on non-targeted or targeted metabolomics and metabolite profiling (focused assays which only refer to a limited array of known biomarkers, applying discriminatory and bioinformatic tools to them) as well as predictive modelling based on clinical trials. The data also highlight pathways and biological compounds that are disrupted at early stages of the diseases, in order to help elucidate target compounds and the pathophysiology of the considered diseases for early prognosis and diagnosis using noninvasive samples (saliva, sputum, serum, plasma, blood, urine, tissue, faecal water or faeces). In the tables, the candidate metabolites for biomarkers of diagnosis, or the biomarkers themselves, are detailed, indicating the type of sample in which they were detected and their up-or down-regulation (if calculated). The metabolites derived from each study have been filtered carefully, according to the analytical platform, and biostatistical discriminant analyses developed. Among the pool of data provided, those reaching a level of significance of p=0.05-0.0001, according to the Bonferroni correction, Steel-Dwass t-or Wilcoxon matched pair tests, are shown.

Coumarin derivatives protect against ischemic brain injury in rats

Neuroprotection strategies are of great importance in the treatment of ischemic brain injury. Screening of our in-stock coumarin derivatives identified compound 1 as exhibiting neuroprotective activity. Subsequently, a structural optimization was carried out, which led to the discovery of the potent compound 20. This compound signi ficantly attenuated the damage in a cell line derived from a pheochromocytoma of the rat adrenal medulla induced by oxygen-glucose deprivation in vitro. Furthermore, compound 20 exhibited clear neuroprotection in middle cerebral artery occlusion rats by reducing infarct size and brain-water content, improving neurological function, and suppressing neuronal loss and neuropathological changes in the cortex and hippocampus. Pharmacokinetic evaluation indicated that compound 20 could penetrate the blood-brain barrier of rats.

CATALYST CONTAINING AMIDINE GROUPS

The use of an amidine of formula (I) and/or a conversion product thereof as a catalyst for the crosslinking of a composition based on silane group-containing polymers. The amidine of formula (I) and the conversion products thereof are essentially odourless at room temperature and non-volatile and accelerate the crosslinking of the composition very well without impairing the storage stability of the composition, and are very compatible in the composition. As a result, the compositions do not have a tendency to separate, migrate or evaporate the catalyst.

Perovskite type oxide-supported Ni catalysts for the production of 2,5-dimethylfuran from biomass-derived 5-hydroxymethylfurfural

The hydrogenolysis of C-O and C=O in 5-hydroxymethylfurfural for the production of furan biofuel 2,5-dimethylfuran (DMF) is of great importance for biomass refining. However, development of non-noble metal-based catalysts which perform stably for this process is still challenging. Here, perovskite-supported Ni catalysts were used for the hydrogenolysis of 5-hydroxymethylfurfural at 230C, with 98.3% yield of DMF being obtained. The effects of reaction conditions such as temperature and pressure were investigated and discussed, and the catalyst could maintain good activity after being used at least 5 times. In order to further explore the reaction mechanism, dynamic experiments at different times were carried out and a possible reaction pathway was proposed. The development of efficient perovskite-supported Ni catalysts verified their great potential in biomass conversion.
