Isoxazol-5-amine (cas: 14678-05-8) belongs to isoxazole derivatives. Isoxazoles are aromatic heterocycles containing an N–O bond. The weakness of this bond allows the ring opening of these heterocycles under reductive conditions. The most common methods for N–O bond cleavage in isoxazoles are hydrogenation with palladium or platinum catalysts or with Raney Ni. Recent developments have shown that Mo(CO)6 efficiently cleaves the N–O bond in isoxazoles.Related Products of 14678-05-8

The aromatic compounds of the thick-skinned melon “Golden Phoenix” were detected by combining solid phase micro-extraction with GC-MS method. The “Golden Phoenix” melons were stored in two different conditions (CA conditions: temperature 6±0.5°C, O₂ 4%-6%, CO₂ 0.2%-0.5%, and ozone storage conditions: 0.45 μL/L ozone for 3 min every 48 h). More 30 volatile compounds of thick-skinned melons were detected after they were stored for 52 d. Of them 20 esters were identified tentatively and their peak areas reached 85.49% with CA storage, and 17 esters were identified tentatively and their peak areas reached 67.15% with ozone storage. The esters were the main aromatic compounds of the thick-skinned melons.

Soil metabolism of the herbicide isoxaben in winter wheat crops was written by Rouchaud, Jean;Gustin, Fabrice;Callens, Dany;Van Himme, Michel;Bulcke, Robert. And the article was included in Journal of Agricultural and Food Chemistry in 1993.HPLC of Formula: 14678-05-8 This article mentions the following:

Winter wheat fields were treated with the herbicide isoxaben after sowing. Trials were made in 1990-1991 and 1991-1992. The main isoxaben soil metabolite was demethoxyisoxaben (N-[3-(1-ethyl-1-methylpropyl)isoxazol-5-yl]-2-hydroxy-6-methoxybenzamide), i.e., the monodemethoxylation product of isoxaben. 5-Isoxazolone (3-(1-ethyl-1-methylpropyl)isoxazolin-5-one) was the second main isoxaben metabolite. When 5-aminoisoxazole (5-amino-3-(1-ethyl-1-methylpropyl)isoxazole) was detected in soil, it always was at very low concentrations It never accumulated in soil; 4 mo before winter wheat harvest, it could not be detected in soil. Benzamides 2,6-dimethoxybenzamide and 2-hydroxy-6-methoxybenzamide and 2,6-dimethoxybenzoic acid also were detected in soil. Organic fertilizer treatments increased isoxaben soil persistence. At the crop’s end, their effects, however, progressively disappeared, the soil residues of isoxaben and of its metabolites becoming very low and similar in the organic fertilizer treated and untreated plots. 5-Aminoisoxazole was not detected. Thus, isoxaben was soil-metabolized into nontoxic products, unable to generate toxic ones, during the wheat crops whose soil had been treated or not treated with organic fertilizers. In the experiment, the researchers used many compounds, for example, Isoxazol-5-amine (cas: 14678-05-8HPLC of Formula: 14678-05-8).

14678-05-8, Name is Isoxazol-5-amine, belongs to isoxazole compound, is a common compound. category: IsoxazolesIn an article, once mentioned the new application about 14678-05-8.

Diastereoselectivity and configurational preference for synthetic reaction of novel bis-Betti base derivatives of 2,6-dihydroxynaphthalene were studied through density functional theory (DFT). Enthalpy, entropy and Gibbs free energy of reactions as well as stereochemistry, thermodynamic stability and spectroscopic analysis of products were investigated. The calculated 1H nuclear magnetic resonance (NMR) and infrared (IR) spectra of different configurations were compared to experimental data in order to find the preferred isomer. The diastereoselectivity of reaction was estimated through the calculated equilibrium distribution of stereoisomers. According to these results, preparation of bis-Betti bases is an exothermic process accompanied by a decrease in entropy. The calculated gas phase heats of formation of title compounds are positive. Since the energy difference between stereoisomers is quite small, the change of Gibbs free energy during the reaction favors one configuration over other possibilities. These results are in good agreement with the experimental observations.

The answer is in thermodynamics and kinetics.In a document type is Conference Paper, and a compound is mentioned, 14678-05-8, Isoxazol-5-amine, introducing its new discovery.

It is known that ciliates exhibit chemosensory behavior. An assay implementing this response was performed with Tetrahymena thermophila, a well-studied representative of the ciliates. A concentration-dependent avoiding reaction was observed for all substances of the test battery, comprising a heterogeneous set of 43 compounds from the European Inventory of Existing Chemicals. Comparisons were made between toxic data from this chemosensory test and chemical concentrations leading to effects on Tetrahymena growth, and EC values from recommended aquatic toxicity tests. Low correlation coefficients indicate that the chemosensory response reflects chemical interactions, which cannot be adequately explained by these other tests. The chemosensory assay proved to be more sensitive in the majority of cases than the Tetrahymena growth test and standard tests with fish and Daphnia. Tetrahymena is able to recognize and avoid about half the substances at concentrations lower than those effective in the algae growth inhibition test. The behavioral response of Tetrahymena could provide further toxicological information and serve as a complementary sublethal end point for ecotoxicological screening purposes.

Quality Control of Isoxazol-5-amine, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 14678-05-8, name is Isoxazol-5-amine. In an article，Which mentioned a new discovery about 14678-05-8

Although some findings have reported the medicinal properties of Jimson weed (Datura stramonium L.), there exist some serious neurological effects such as hallucination, loss of memory and anxiety, which has been reported in folklore. Consequently, the modulatory effect of alkaloid extracts from leaf and fruit of Jimson weed on critical enzymes of the purinergic [ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase), ecto-5?-nucleotidase (E-NTDase), alkaline phosphatase (ALP) and Na+/K+ ATPase] system of neurotransmission was the focus of this study. Alkaloid extracts were prepared by solvent extraction method and their interaction with the activities of these enzymes were assessed (in vitro) in rat brain tissue homogenate and in vivo in rats administered 100 and 200 mg/kg body weight (p.o) of the extracts for thirty days, while administration of single dose (1 mg/kg body weight; i.p.) of scopolamine served as the positive control. The extracts were also investigated for their Fe2+ and Cu2+ chelating abilities and GC?MS characterization of the extracts was also carried out. The results revealed that the extracts inhibited activates of E-NTPDase, E-NTDase and ALP in a concentration dependent manner, while stimulating the activity of Na+/K+ ATPase (in vitro). Both extracts also exhibited Fe2+ and Cu2+ chelating abilities. Considering the EC50 values, the fruit extract had significantly higher (P < 0.05) modulatory effect on the enzymes? activity as well as metal chelating abilities, compared to the leaf extract; however, there was no significant difference (P > 0.05) in both extracts? inhibitory effects on E-NTDase. The in vivo study revealed reduction in the activities of ENTPDase, E-NTDase, and Na+/K+ ATPase in the extract-administered rat groups compared to the control group, while an elevation in ALP activity was observed in the extract-administered rat groups compared to the control group. GC?MS characterization revealed the presence of atropine, scopolamine, amphetamine, 3-methyoxyamphetamine, 3-ethoxyamhetamine cathine, spermine, phenlyephirine and 3-piperidinemethanol, among others in the extracts. Hence, alterations of activities of critical enzymes of purinergic signaling (in vitro and in vivo) by alkaloid extracts from leaf and fruit of Jimson weed suggest one of the mechanisms behind its neurological effects as reported in folklore.
