2,6-DIMETHYL-N-(5-METHYL-3-ISOXAZOLYL)BENZAMIDE

The molecule of the title compound, 2,6-dimethyl-N(5-methyl-3-isoxazolyl)benzamide, consists of two parts which are approximately planar, an N-3-amido-5-methylisoxazole group and a 2,6-dimethyl-benzene group. The least-squares planes of the isoxazole and benzene rings make an angle of 83.54(9)degrees. An intramolecular C-H…O hydrogen bond [2.877(3)Angstrom, 110(2)degrees] forms a pseudo six-membered ring and contributes to the planarity of the isoxazole group. A delocalized orbital spreads out from the isoxazole ring to the carbonyl group. The structure is made up of dimers; molecules belonging to the same dimer are related by a centre of symmetry and linked together by two N-H…N hydrogen bonds[2.983(3) Angstrom, 163(3)degrees].

Fluorescent probes of the isoxazole-dihydropyridine scaffold: MDR-1 binding and homology model

Isoxazole-1,4-dihydropyridines (IDHPs) were tethered to fluorescent moieties using double activation via a lanthanide assisted Weinreb amidation. IDHP-fluorophore conjugate 3c exhibits the highest binding to date for IDHPs at the multidrug-resistance transporter (MDR-1), and IDHP-fluorophore conjugates 3c and 7 distribute selectively in SH-SY5Y cells. A homology model for IDHP binding at MDR-1 is presented which represents our current working hypothesis. (C) 2013 Elsevier Ltd. All rights reserved.

Medicinal Chemistry Perspective of Fused Isoxazole Derivatives

Nitrogen containing heterocyclic rings with an oxygen atom is considered as one of the best combination in medicinal chemistry due to their diversified biological activities. Isoxazole, a five membered heterocyclic azole ring is found in naturally occuring ibetonic acid along with some of the marketed drugs such as valdecoxib, flucloxacillin, cloxacillin, dicloxacillin, and danazol. It is also significant for showing antipsychotic activity in risperidone and anticonvulsant activity in zonisamide, the marketed drugs. This review article covers research articles reported till date covering biological activity along with SAR of fused isoxazole derivatives.

3-Pyridylisoxazoles as prototypes of antiaggregatory agents

A series of 5-alkyl-3-pyridylisoxazoles was synthesized using the 3-(3-pyridyl)isoxazole scaff old. All compounds of the series possessed antiaggregatory activity in the concentration range of 6aEuro cent 10(-6)-6aEuro cent 10(-4) mol L-1. Analysis of the experimental data on the antiaggregatory activity revealed the presence of spatial constraints for the alkyl substituents in position 5 of the isoxazole ring. 5-Alkyl-3-(3-pyridyl)isoxazoles are rather selective for platelet membrane receptors.

Elucidation of a Novel Bioactivation Pathway of a 3,4-Unsubstituted Isoxazole in Human Liver Microsomes: Formation of a Glutathione Adduct of a Cyanoacrolein Derivative after Isoxazole Ring Opening

Studies on the biotransformation of isoxazole rings have shown that molecules containing a C3-substituted isoxazole or a 1,2-benzisoxazole can undergo a two-electron reductive ring cleavage to form an imine. In the absence of a C3 substituent, the isoxazole ring opens via deprotonation of the C3 proton followed by N-O bond cleavage to yield an alpha-cyanoenol analog. We report the identification of a novel bioactivation pathway of a 3,4-unsubstituted isoxazole in human liver microsomes. After the enzyme-catalyzed cleavage of the 3,4-unsubstituted isoxazole ring of N-((2-isopropyl-7-methyl-1-oxoisoindolin-5-yl)methyl)isoxazole-5-carboxamide (P) in human liver microsomes, the formed alpha-cyanoenol (M1) condenses with formaldehyde to generate an alpha,beta-unsaturated Michael acceptor intermediate (a cyanoacrolein derivative, VII), which further reacts with the cysteinyl thiol of glutathione to yield a GSH adduct of a cyanoacrolein derivative (M3). The same adduct also is formed when M1, generated in 0.1 N NaOH aqueous solution, reacts with formaldehyde and GSH. (13)C-labeled methanol was used to confirm that methanol from the drug stock solution was oxidized by liver microsomal enzymes to formaldehyde and the carbon atom from methanol was finally incorporated in the corresponding GSH adduct. The formation of isoxazole ring-opened products (M1 and M2) in human liver microsomes is NADPH-dependent. M1 and M2 were found in human liver microsomes preincubated with 1-aminobenzotriazole (1 mM) and NADPH (5 mM) at similar to 10% of the levels found in the samples in the absence of 1-aminobenzotriazole, suggesting that this biotransformation pathway is primarily catalyzed by cytochrome P450. The formation of M3 also was inhibited by 1-aminobenzotriazole at a similar level.

A collection of 91 3-(arylthiomethyl)isoxazole-4,5-dicarboxamides was prepared starting from dimethyl 3-(chloromethyl)isoxazole-4,5-dicarboxylate. The thioether moieties in these compounds were subsequently oxidized to give the corresponding 3-(arylsulfonylmethyl)isoxazole-4,5-dicarboxamides. By carefully controlling stoichiometry and reaction conditions, the C4 and C5 carbomethoxy groups could be differentially derivatized to carboxamides. A total of 182 trisubstituted isoxazoles are reported and deposited in the National Institutes of Health Molecular Repository; an 80 compound subset was evaluated for insecticidal activity.
