Oligo switches: photoresponsive oligonucleotide conjugates by solid-supported click chemistry

Photoresponsive oligonucleotides (ONs) incorporating isoxazole-linked azobenzene (AB) moieties were prepared by resin-supported nitrile oxide-alkyne cycloaddition (NOAC) chemistry. The thermal and photochromic properties of the modified ONs were significantly influenced by the extent of pi-conjugation between the isoxazole and the AB modules.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 17153-20-7 is helpful to your research. Application In Synthesis of 3-Methylisoxazole-4-carboxylic acid.

Novel Hybrid Molecules of Isoxazole Chalcone Derivatives: Synthesis and Study of In Vitro Cytotoxic Activities

Background: Now-a-days, the model of hybrid drugs has acquired recognition in medicine due to their significant role in the treatment of different health problems. Methods: We have synthesized new series of isoxazole-chalcone conjugates (14a-m) by the Claisen-Schmidt condensation of suitable substituted acetophenones with isoxazole aldehydes (12a-d). In vitro cytotoxic activity of the synthesized compounds was studied against four different selected human cancer cell lines by using sulforhodamine B (SRB) method. Results: The adopted scheme resulted in good yields of new series of isoxazole-chalcone conjugates (14a-m). Potent cytotoxic activity was observed for compounds -14a, 14b, 14e, 14i, 14j and 14k against prostate DU-145 cancer cell line. Conclusion: The observed potent cytotoxic activities were due to the presence of 3,4,5-trimethoxyphenyl group.

Synthesis of 3-phenyl-5-(trifluoromethyl)isoxazole and 5-phenyl-3-(trifluoromethyl)isoxazole

Reaction of 4,4,4-trifluoro-1-phenyl-1,3-butanedione with hydroxylamine led to the formation of 5-hydroxy-3-phenyl-5-(trifluoromethyl)-4,5-dihydroisoxazole which was dehydrated to 3-phenyl-5-(trifluoromethyl)isoxazole. This isomer can also be synthesized by reaction of 4-chloro-4-phenyl-1,1,1-trifluoro-3-buten-2-one with sodium azide. The regioisomer, 5-phenyl-3-(trifluoromethyl)isoxazole was synthesized by reaction of 1,1,1-trifluoro-4-phenylbut-3-yn-2-one with hydroxylamine and by the reaction of 3-chloro-1-phenyl-4,4,4-trifluorobut-2-en-1-one with sodium azide.

Mechanism of the migration of the substituent in 1,2,3,7a-tetrahydroimidazo[1,2-b]isoxazole derivatives

The thermolysis of 1,2,3,7a-tetrahydroimidazo[1,2-b]isoxazole derivatives results in intramolecular rearrangements by two main pathways. One rearrangement affords azomethine ylide derivatives. Another rearrangement leads to the migration of the substituent from position 7a to the nitrogen atom. The rate constants of these reactions were determined. Quantum chemical calculations by the DFT method were carried out. Based on the data for the migration of the substituent, the concerted mechanism was proposed.

Development of 4-oxime-1,8-naphthalimide as a bioorthogonal turn-on probe for fluorogenic protein labeling

4-Oxime-1,8-naphthalimide was reported as a novel bioorthogonal turn-on probe based on 1,3-dipolar cycloaddition reactions between in situ generated nitrile oxide and alkenes/alkynes. The resulting isoxazole products displayed dramatically strong fluorescence enhancement upon photoirradiation through isoxazole-oxazole photoisomerization. This new methodology was successfully applied for in situ fluorogenic protein labeling.

Synthesis and Characterization of Isoxazole-Based Energetic Plasticizer Candidates EEIN and IDN

This study presents the synthesis of ethyl 5-[(nitrooxy)methyl]isoxazole-3-carboxylate (EEIN) and isoxazole-3,5-diylbis(methylene) dinitrate (IDN). These compounds, each derived from 5-(hydroxymethyl)isoxazole-3-carboxylate, were fully characterized and their explosive sensitivity properties were determined. EEIN was isolated as a solid material with a relatively low melting temperature and IDN was isolated as a liquid with excellent energetic performance properties. In addition, we report the molecular structure of ethyl 5-[(nitrooxy)methyl]isoxazole-3-carboxylate as determined by single-crystal X-ray diffractometry. These compounds possess promising properties as plasticizing ingredients in propellant formulations.

Syntheses of 3-cyano-7- and 8-substituted-4-(beta -D-ribofuranosyl)-1H-1,5-benzodiazepines were reported. Treatment of isoxazole carbaldehyde with 1,2-diamino-4-nitrobenzene in chloroform gave a Schiffs base, 4-(2-amino-5-nitrophenyl)iminomethyl-5-(2,3,5-tri-O-benzoyl-beta -D-ribofuranosyl)isoxazole in 82% yield with no trace of the other regioisomer. The cyclocondensation of the resulting Schiffs base in benzene containing trifluoroacetic acid (TFA) gave 3-cyano-8-nitro-4-(2,3,5-tri-O-benzoyl-beta -D-rbofuranosyl)-1H-1,5-benzodiazepine in 49% yield. The same reac tion of isoxazole carbaldeyde with 1,2-diamino-4-methoxy- and 4-chlorobenzenes afforded the corresponding Schiffs bases. Extending the reaction time for Schiff’s base gave the corresponding cyanobenzodiazepines in good yields. Debenzoylation of the compounds with sodium methoxide produced deprotected C-nucleosides.
