Journal of Medicinal Chemistry, 1977
A series of 3-halo-5-phenyl- and 3-phenyl-5-haloisoxazoles has demonstrated anthelmintic activity at doses ranging from 16 to 500 mg/kg orally against the rat roundworm, Nippostrongylus braziliensis. In the 5-phenyl series a halogen at the 3 position of the isoxazole ring was required for activity.

Isoxazoles with antipicornavirus activity
Journal of Medicinal Chemistry, 1985The synthesis and evaluation of a series of 3,5-disubstituted isoxazoles as antipicornavirus agents have led to the discovery of several compounds effective in vitro against rhinovirus type 2 and poliovirus type 2. Compound 32 was found more effective than 4',6-dichloroflavan against both viruses and was evaluated orally in mice infected ...

Acta Crystallographica Section C Crystal Structure Communications, 1996
The title compound, ethyl 3-(9-anthryl)-5-methyl-4-isoxazolecarboxylate, C 21 H 17 NO 3 , possesses two planar ring systems that lie at 80° from coplanarity. The bond linking the two ring systems is 1.489 (3) A, indicating only partial conjugation between the two ring systems.

Isoxazoles, benzisoxazoles, isoxazolines, and isoxazolidines are classes of heterocyclic compounds having a remarkable number of applications and are very versatile building blocks in organic synthesis. The major developments on the chemistry of these heterocycles reported in the literature from 1996 to 2006 are reviewed.

Inorganica Chimica Acta, 1975
Abstract A number of divalent 3d metal chloride and perchlorate complexes with isoxazole were obtained by interaction of salt and ligand in triethyl orthoformate-ethanol. Characterization of these complexes was based on spectral (ir--electronic), magnetic and conductance evidence.

Isoxazoles I: Protonation of Isoxazole Derivatives in Aqueous Sulfuric Acid
Journal of Pharmaceutical Sciences, 1973The protonation of 3-amino-5-methylisoxazole, 5-amino-3,4-dimethylisoxazole, sulfamethoxazole (N-sulfanilamido-5-methyl-3-isoxazole), and sulfisoxazole (N-sulfanilamido-3,4-dimethyl-5-isoxazole) in aqueous sulfuric acid was studied. The pKSH+ and log SH+/S or log SH2+2/SH+ values were determined by UV spectrophotometry.
