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.

1-(3-p-Tolylisoxazol-5-yl)cyclohexanol

The title compound, C16H19NO2, contains two molecules in the asymmetric unit. Each molecule is composed of three interconnected rings, two essentially planar rings, viz. the isoxazole and the methylbenzyl aromatic ring [maximum deviations of 0.0027 (13) and 0.0031 (19) angstrom from the isoxazole and methylbenzyl ring planes, respectively, in the first molecule, 0.0018 (12) and 0.019 (2) angstrom in the second molecule], and one cyclohexanol ring having a chair conformation. Although the two molecules have similar bond distances and angles, they differ in the orientation of the cyclohexanol ring with respect to the tolylisoxazole unit. In the first molecule, the dihedral angle between the isoxazole and methylbenzyl rings is 22.03 (8)degrees and between the isoxazole and cyclohexanol rings is 30.15 (8)degrees. The corresponding values in the second molecule are 6.13 (10) and 88.44 (8)degrees, respectively. In the crystal, the molecules are linked by O-H center dot center dot center dot O and O-H center dot center dot center dot N hydrogen bonds, building up a zigzag chain parallel to the a axis.

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. you can also check out more blogs about 22264-50-2. Product Details of 22264-50-2.

Isoxazole Alters Metabolites and Gene Expression, Decreasing Proliferation and Promoting a Neuroendocrine Phenotype in beta-Cells

Novel strategies are needed to modulate beta-cell differentiation and function as potential beta-cell replacement or restorative therapies for diabetes. We previously demonstrated that small molecules based on the isoxazole scaffold drive neuroendocrine phenotypes. The nature of the effects of isoxazole compounds on beta-cells was incompletely defined. We find that isoxazole induces genes that support neuroendocrine and beta-cell phenotypes and suppresses genes important for proliferation. Isoxazole alters beta-cell metabolites and protects glucose-responsive signaling pathways under lipotoxic conditions. Finally, we show that isoxazole improves glycemia in a mouse model of beta-cell regeneration. Isoxazole is a prime candidate to alter cell fate in different contexts.

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.
