The propargyl alcohol on reaction with aldoxime and NaOCl in DCM gave exclusively (3-arylisoxazol-5-yl) methanol 1. The compound 1 was oxidized to an aldehyde 2 followed by reaction with aniline resulted in Schiff’s base 3. The compounds 3 were further reacted with various aldehydes having alpha-hydrogen using molecular iodine as catalyst and which yielded 5-(3-alkylquinolin-2-yl)-3- aryl isoxazole derivatives 4. All the final compounds 4 were screened against four human cancer cell lines (A549, COLO 205, MDA-MB 231 and PC-3) and among these compounds 4n showed potent cytotoxicity against all the cell lines at IC50 values of <12 muM.

Nonnucleoside reverse transciptase inhibitors (NNRTI) are a class of drug molecules with a specific target of HIV-1 reverse transcriptase (RT). In the present work, we evaluated a set of selected oxazole and carboxamide derivatives to identify potential pharmacophoric features using molecular docking approach. The docking approach employed has been validated by enrichment factor calculation at top 1% (EF1%). It shows a considerable improvement in EF1%value compared to earlier reported study carried out on specific dataset of ligands and decoys for RT, in the directory of useful decoys (DUD). The carboxamide derivatives show better activity as NNRT inhibitors than oxazole derivatives. From this study, four pharmacophoric groups including a triazine ring, an aniline substituent, a benzyl amide moiety and a trimethylphenoxy substituent have been recognized and used for designing new NNRT inhibitors. Newly designed molecules show significant enhancement in docking scores over the native ligand, parent and other training set molecules. In addition, some functional groups have also been identified to assist in improving the activity of these pharmacophores. Thus a nitrile group, an amide and fluoro substitution turn out to be an important requisite for NNRT potential inhibitors.

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Computed Properties of C10H7NO4, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 33282-15-4, name is 5-(4-Hydroxyphenyl)isoxazole-3-carboxylic acid. In an article，Which mentioned a new discovery about 33282-15-4

The chemical transformation of CO2 under mild conditions remains a great challenge because of its exceptional kinetic and thermodynamic stability. Two important reactions in the transformation of CO2 are the N-formylation reaction of amines using hydrosilanes and CO2, and the cycloaddition of CO2 to epoxides. Here, we report the high efficiency of bifunctional metallosalen complexes bearing quaternary phosphonium salts in catalyzing both of these reactions under solvent-free, mild conditions without the need for co-catalysts. The catalysts’ bifunctionality is attributed to an intramolecular cooperative process between the metal center and the halogen anion. Depending on the reaction, this activates CO2 by permitting either the synergistic activation of Si?H bond via metal?hydrogen coordinative bond (M?H) or the dual activation of epoxide via metal?oxygen coordinative bond (M?O). The one-component catalysts are also shown to be easily recovered and reused five times without significant loss of activity or selectivity. The current results are combined with previous work in the area to propose the relevant reaction mechanisms.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 33282-15-4, help many people in the next few years.Computed Properties of C10H7NO4

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.
