Developing Isoxazole as a Native Photo-Cross-Linker for Photoaffinity Labeling and Chemoproteomics.
Angewandte Chemie, 2022Photoaffinity labeling is a powerful technique to interrogate drug-protein interactions in native cellular environments. Photo-cross-linkers are instrumental for this technique. However, the introduction of unnatural photo-cross-linkers may significantly

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 ...
