In an article，Which mentioned a new discovery about 87988-94-1

The kinetics of enolization and degradation of N-(5-methyl-4-isoxazolyl)- 4-amino-1,2-naphthoquinone (1) was investigated in aqueous solutions over a pH range of 7.30 to 12.25, at 35 C and at constant ionic strength (mu = 0.5) using reversed-phase HPLC. Pseudo-first-order kinetics was observed throughout the pH range studied. The rate of enolization (k(e)), the keto- enol equilibrium constant (K(t)), and specific base catalysis rate constant (k(OH)) were determined. Good agreement between the theoretical pH-rate profile and the experimental data supports the proposed transformation process. The average recovery for 1 and its tautomerization product 2- hydroxy-N-(5-methyl-4-isoxazolyl)-1,4-naphthoquinone 4-imine (2) from mixtures of different composition was evaluated.

Synthetic Route of 87988-94-1, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.87988-94-1, Name is 5-Methylisoxazol-4-amine, molecular formula is C4H6N2O. In a Article，once mentioned of 87988-94-1

The rational design and synthesis of a highly potent inhibitor of HIV-1 protease have been accomplished. The inhibitor, SB 206343, is based on a model derived from the structure of the MVT-101/HIV-1 protease complex and contains a 4(5)-acylimidazole ring as an isosteric replacement for the P1′- P2′ amide bond. It is a competitive inhibitor with an apparent inhibition constant of 0.6 nM at pH 6.0. The three-dimensional structure of SB 206343 bound in the active site of HIV-1 protease has been determined at 2.3 A resolution by X-ray diffraction techniques and refined to a crystallographic discrepancy factor, R (=Sigma||F(o)| – |F(c)|?Sigma|F(o)|), of 0.194. The inhibitor is held in the enzyme by a set of hydrophobic and polar interactions. N-3 of the imidazole ring participates in a novel hydrogen- bonding interaction with the bound water molecule, demonstrating the effectiveness of the imidazole ring as an isosteric replacement for the P1′- P2′ amide bond in hydroxyethylene-based HIV-1 protease inhibitors. Also present are hydrogen-bonding interactions between N-1 of the imidazole ring and the carbonyl of Gly-127 as well as between the imidazole acyl carbonyl oxygen and the amide nitrogen of Asp-129, exemplifying the peptidomimetic nature of the 4(5)-acylimidazole isostere. All of these interactions are in qualitative agreement with those predicted by the model.

87988-94-1, Name is 5-Methylisoxazol-4-amine, belongs to isoxazole compound, is a common compound. COA of Formula: C4H6N2OIn an article, once mentioned the new application about 87988-94-1.

4-Aminoisoxazoles can be acylated with a wide variety of activated carboxylic acids.Hydrogenation of the resulting amides gives alpha-(acylamino)enaminones, which cyclize to 4(5)-acylimidazoles upon treatment with base.This method allows for the synthesis of acylimidazoles with a wide range of substituents at C-2.Utilization of N-substituted 4-aminoisoxazoles in the same sequence of reactions yields 1-substituted 5-acylimidazoles, a substitution pattern not otherwise easily prepared.Treatment of alpha-(acylamino)enaminones, derived from N-unsubstituted isoxazoles, with primary amines leads to incorporation of the amine at the beta-position with concomitant expulsion of ammonia.This sequence efficiently yields 1-substituted and 1,2-disubstituted 4-acylimidazoles but does not give satisfactory yields of 5-substituted 4-acylimidazoles due to steric inhibition of the amine exchange.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Product Details of 87988-94-1. Introducing a new discovery about 87988-94-1, Name is 5-Methylisoxazol-4-amine

The degradation kinetics of N-(5-methyl-4-isoxazolyl)-4-amino-1,2- naphthoquinone (1) was studied in aqueous solution over a pH range of 0.65- 7.50, at 35 C and at a constant ionic strength of 0.5. The degradation rates were determined by high-pressure liquid chromatography and were observed to follow pseudo-first-order kinetics with respect to the concentration of 1. The pH-rate profile was linear with slope -1 under acidic pH, becoming pH independent from 3.50 to 7.50. Good agreement between the theoretical pH-rate profile and the experimental data supports the proposed degradation process. The catalytic rate constants for hydrogen ion and water were k(H) = 0.901 M-1 h-1 and k(o) = 1.34 x 10-3 h-1, respectively. These data are appropriate to develop a stable dosage form of 1. The accuracy, peak sharpness, and asymmetry factor for the analytical method were determined.

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.Product Details of 87988-94-1, you can also check out more blogs about87988-94-1
