Efficient Transformation of Alkyl 3-nitro-5-(aryl/alkyl) isoxazole-4-carboxylates into 3-amino- and 3-hydrazinyl-5-aryl/alkyl-isoxazole-4-carboxylates in Aqueous Solution

An efficient protocol for transforming alkyl 3-nitro-5-(aryl/alkyl)isoxazole-4-carboxylates into 3-amino- and 3-hydrazinyl-5-aryl/alkyl-isoxazole-4-carboxylates is described. The reaction that is carried out in aqueous acetonitrile solution generally afford the products without any chromatographic purification. Investigations with the substrate scope reveal that this protocol is compatible only when the ester group is present at the C-4 position of the isoxazole ring.

Isoxazole derivatives of silatrane: synthesis, characterization, in silico ADME profile, prediction of potential pharmacological activity and evaluation of antimicrobial action

A new family of mono- (3a-h) and bis- (4a-g) isoxazole-bridged silatranes has been synthesized by the reaction of 3-aminopropylsilatrane (1) and 3-substituted 5-chloro-methylisoxazoles (2a-h). The structure of the isoxazole-silatrane hybrids is characterized by elemental analysis, FT-IR, UV, NMR (H-1,C-13,Si-29 and(15)N) spectroscopy, high-resolution mass spectrometry, and X-ray diffraction analysis. Thein silicoADME (absorption, distribution, metabolism, excretion) assessment reveals that properties of mono-adducts (3a-h) are similar to those of drugs obeyed to the Lipinski’s rule. The calculated screening of potential pharmacological activity profiles (in silicoPASS program) of isoxazole-silatranes shows that all synthesized compounds (both mono- and bis-substituted) may have high antitumor action, unlike starting isoxazoles. The preliminary screening of the synthesized silatranes for antimicrobial activity againstEnterococcus durans,Bacillus subtilis,Escherichia coli,andPseudomonas aeruginosaindicates that all test samples are active only against gram-positive microorganisms. Silatrane3fdisplays minimal inhibitory concentration (MIC 12.5 and 6.2 mu g ml(-1)) againstE. duransandB. subtilisas compared with standard drug gentamicin (MIC 25 and 50 mu g ml(-1)).

Design, synthesis and antitrypanosomatid activities of 3,5-diaryl-isoxazole analogues based on neolignans veraguensin, grandisin and machilin G

Using bioisosterism as a medicinal chemistry tool, 16 3,5-diaryl-isoxazole analogues of the tetrahydrofuran neolignans veraguensin, grandisin and machilin G were synthesized via 1,3-dipolar cycloaddition reactions, with yields from 43% to 90%. Antitrypanosomatid activities were evaluated against Trypanosoma cruzi, Leishmania (L.) amazonensis and Leishmania (V.) braziliensis. All compounds were selective for the Leishmania genus and inactive against T. cruzi. Isoxazole analogues showed a standard activity on both promastigotes of L. amazonensis and L. braziliensis. The most active compounds were 15, 16 and 19 with IC50 values of 2.0, 3.3 and 9.5 mu M against L. amazonensis and IC50 values of 1.2, 2.1 and 6.4 mu M on L. braziliensis, respectively. All compounds were noncytotoxic, showing lower cytotoxicity (>250 mu M) than pentamidine (78.9 mu M). Regarding the structure-activity relationship (SAR), the methylenedioxy group was essential to antileishmanial activity against promastigotes. Replacement of the tetrahydrofuran nucleus by an isoxazole core improved the antileishmanial activity.

Polymorphic and solvate structures of ethyl ester and carboxylic acid derivatives of WIN 61893 analogue and their stability in solution

3-Ethyl ester- (1) and 3-carboxylic acid-isoxazole (2) derivatives of an antiviral drug analogue WIN 61893 were synthesized and characterized by X-ray crystallography and NMR spectroscopy. Crystallization experiments afforded two polymorphic structures for the ethyl ester derivative and two solvate structures for the carboxylic acid derivative based on their ability to form intermolecular hydrogen bonding interactions with the solvent molecules. The conformations of the derivatives depended greatly on the orientation of the planar isoxazole and phenyl-oxadiazole ring systems with respect to one another and were found to take up perpendicular, linear or tilted conformations. The carboxylic acid derivative was furthermore observed to undergo isoxazole ring cleavage by decarboxylation in DMSO solution and transforming into a beta-keto nitrile ring-opening product over several days, whereas, the isoxazole ring of the ethyl ester derivative was not affected.

Synthetic Route of 446292-10-0, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about 446292-10-0 is helpful to your research.

Reactions of an imidazo[4,5-c]isoxazole-6-carboxylate with electron deficient acetylenes

The synthesis of the first examples of the imidazo[4,5-c]isoxazole ring system has recently been reported,(2) but little is known about the chemistry of this heterocycle. In this paper we describe our investigation into the behaviour of an imidazo[4,5-c]isoxazole-6-carboxylate ester with acetylenic esters and ketones. A complex reaction sequence is found to occur, involving addition of two molecules of alkyne followed by ring opening and fragmentation, leading to the formation of 2-pyrrol-2-yl imidazoles in moderate yield. The mechanism and scope of the reaction is discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
