Isoxazole ring as a useful scaffold in a search for new therapeutic agents

Due to its relatively easy synthesis, isoxazole ring has been as an object of interest for chemists and pharmacologists from research groups all over the world. Its chemical modifications include both connection of isoxazole with other aromatic, heteroaromatic or non aromatic rings and substitution with different alkyl groups. Thanks to their usually low cytotoxicity, isoxazole derivatives are still popular scaffolds for the development of new agents with variable biological activities, such as antimicrobial, antiviral, anticancer, anti-inflammatory, immunomodulatory, anticonvulsant or anti-diabetic properties. This review discusses the chemical structure of recently developed isoxazole derivatives with regards to their activity and potential therapeutic use. (C) 2017 Elsevier Masson SAS.

Interesting results of catalytic hydrogenation of 3-(2-nitrophenyl)isoxazoles and 3-(nitrophenyl)-4,5-dihydroisoxazoles

The palladium-on-carbon assisted hydrogenolysis of substituted 3-(2-nitrophenyl)isoxazoles, irrespective of substitution on the isoxazole ring, invariably leads to reduction of the nitro to the amino group with concomitant regiospecific ring closure to yield substituted 4-aminoquinolines. In contrast similar hydrogenation of 3-(2-, 3-, and 4-nitrophenyl)-4,5-dihydroisoxazoles (2-isoxazolines) results in reduction of the nitro group only with conservation of the dihydroisoxazole ring to yield the corresponding 3-(aminophenyl)-4,5-dihydroisoxazoles.

Effect of isoxazole derivatives of tetrahydrofuran neolignans on intracellular amastigotes of Leishmania (Leishmania) amazonensis: A structure-activity relationship comparative study with triazole-neolignan-based compounds

Isoxazole analogues derived from the neolignans veraguensin, grandisin, and machilin G were previously synthesized with different substitution patterns through the bioisosterism strategy. These compounds were tested on intracellular amastigotes of Leishmania (Leishmania) amazonensis; the derivatives proved to be active against intracellular amastigotes, with IC50 values ranging from 0.4 to 25 mu M. The most active analogues were 4 ‘, 14 ‘, 15 ‘, and 18 ‘, with IC50 values of 0.9, 0.4, 0.7, and 1.4 mu M, respectively, showing high selectivity indexes (SI = 277.0; 625.0; 178.5 and 357.1). Overall, the isoxazole analogues did not induce nitric oxide (NO) production by infected cells; there was no evidence that NO influences the antileishmanial mechanism of action, except for compound 4 ‘. Trimethoxy groups as substituents seemed to be critical for antileishmanial activity. The SAR study demonstrated that the isoxazole compounds were more active than 1,2,3-triazole compounds with the same substitution pattterns, demonstrating the importance of the bioisosterism strategy in drug design.

ELECTRON-IMPACT MASS-SPECTRAL FRAGMENTATION PATTERNS OF ISOXAZOLINES

Electron-impact mass spectra of 32 isoxazolines, viz. monocyclic, bicyclic and tricyclic isoxazolines are reported. The major fragmentation pattern for the isoxazolines with alkyl, aryl, methoxycarbonyl, (methylthio)methyl substituents at C-5 is alpha-cleavage while there is a competition between the groups at C-5 for elimination in the case of 5,5-disubstituted isoxazolines. Bicyclic and tricyclic isoxazolines undergo ring fission to afford (isoxazole+allyl radical cation) and (isoxazole + cyclopentane radical cation) respectively, to reduce the ring strain present in the parent isoxazolines. In the case of 5-(2-methylphenyl)-isoxazolines, the isoxazole cation is observed as the base peak arising out or CH3 loss followed by H-migration.

Semisynthesis and acaricidal activities of isoxazole and pyrazole derivatives of a natural product bisdemethoxycurcumin

Sixteen isoxazole and pyrazole derivatives of bisdemethoxycurcumin (BDMC) modified in beta-diketone were synthesized, and their structures were confirmed by IR, H-1 NMR, C-13 NMR, MS and elemental analysis. Preliminary acaricidal activities against female adults of Tetranychus cinnabarinus (Boisduval) and Panonychus citri (McGregor) were evaluated using the slide-dip method. The results indicated that some of these compounds exhibit more pronounced acaricidal activity than BDMC, especially compound 4, which displays acaricidal activity comparable to that of pyridaben.

Isoxazole-Derived Amino Acids are Bromodomain-Binding Acetyl-Lysine Mimics: Incorporation into Histone H4 Peptides and Histone H3

A range of isoxazole-containing amino acids was synthesized that displaced acetyl-lysine-containing peptides from the BAZ2A, BRD4(1), and BRD9 bromodomains. Three of these amino acids were incorporated into a histone H4-mimicking peptide and their affinity for BRD4(1) was assessed. Affinities of the isoxazole-containing peptides are comparable to those of a hyperacetylated histone H4-mimicking cognate peptide, and demonstrated a dependence on the position at which the unnatural residue was incorporated. An isoxazole-based alkylating agent was developed to selectively alkylate cysteine residues in situ. Selective monoalkylation of a histone H4-mimicking peptide, containing a lysine to cysteine residue substitution (K12C), resulted in acetyl-lysine mimic incorporation, with high affinity for the BRD4 bromodomain. The same technology was used to alkylate a K18C mutant of histone H3.
