The design and synthesis of a new class of nonpeptide direct thrombin inhibitors, built on the structure of 1-(pyridin-4-yl)piperidine-4-carboxamide, are described. Starting from a strongly basic 1-amidinopiperidine derivative (6) showing poor thrombin (fIIa) and factor Xa (fXa) inhibition activities, anti-fIIa activity and artificial membrane permeability were considerably improved by optimizing the basic P1 and the X-substituted phenyl P4 binding moieties. Structure-activity relationship studies, usefully complemented with molecular modeling results, led us to identify compound 13b, which showed excellent fIIa inhibition (Ki = 6 nM), weak anti-Xa activity (K i = 5.64 muM), and remarkable selectivity over other serine proteases (e.g., trypsin). Compound 13b showed in vitro anticoagulant activity in the low micromolar range and significant membrane permeability. In mice (ex vivo), 13b demonstrated anticoagulant effects at 2 h after oral dosing (100 mg·kg-1), with a significant 43% prolongation of the activated partial thromboplastin time (aPTT), over controls (P < 0.05).

HPLC of Formula: C9H8O4, In a article, mentioned the application of 70918-54-6, Name is (S)-1,4-Benzodioxane-2-carboxylic acid, molecular formula is C9H8O4

Oximes and oxime ethers are privileged building blocks and can be conveniently converted to ketones, amines, hydroxylamines, and nitriles. We describe the catalytic decarboxylation of aliphatic carboxylic acids to oxime ethers. With AgNO3 as the catalyst, valuable oxime ethers bearing various substituents could be easily obtained. The broad substrate scope, easy accessibility of aliphatic carboxylic acids, and mild reaction conditions make this strategy immediately applicable to the synthesis, late-stage functionalization, and modification of biologically active compounds. Experimental studies show the reaction undergoes a radical process.

HPLC of Formula: C10H10O4, In a article, mentioned the application of 3663-79-4, Name is Methyl 1,4-Benzodioxane-2-carboxylate, molecular formula is C10H10O4

The methyl ester of 1,4-benzodioxane-2-carboxylic acid 1 and the mesylate of 2-hydroxymethyl-1,4-benzodioxane 2 are synthetic intermediates whose enantiomers can be advantageously used to prepare a number of enantiopure 2-substituted 1,4-benzodioxanes from readily accessible (±)-1,4-benzodioxane-2-carboxilic acid. We have previously demonstrated the conglomerate nature of the enantiomeric systems of 1 and 2. Herein, we report the resolution of their racemates by preferential crystallization according to an entrainment procedure. In particular, the entrainment resolution of 1 showed good efficiency, which makes the present method a competitive alternative to the classical resolutions of 1,4-benzodioxane-2-carboxylic acid with dehydroabietylamine and para-substituted 1-phenylethylamines that we have recently reported.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C10H10O4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3663-79-4, in my other articles.

Treatment of O-(beta-arylethyl) arylimidates with 1,3-diiodo-5,5-dimethylhydantoin (DIH) under irradiation with a tungsten lamp in 1,2-dichloroethane gave the corresponding 2,4-diaryl-5-iodoxazoles and 2,4-diaryloxazoles in good to moderate yields, respectively, depending on the aryl group. It was proposed that the reactions proceeded through the formation of N-iodoimidates by the reaction of O-(beta-arylethyl) arylimidates with DIH, followed by the formation of iminyl radicals via homolytic N?I bond cleavage, the 1,5-H shift by the iminyl radicals, the C?I bond formation of the formed carbon-centered radicals with iodine, the nucleophilic cyclization by the imino groups to form 2,4-diaryloxazolines, the oxidation of the formed 2,4-diaryloxazolines to 2,4-diaryloxazoles, and the iodination of the formed 2,4-diaryloxazoles to 2,4-diaryl-5-iodoxazoles with DIH.
