Human carbonic anhydrase inhibitory profile of mono- and bis-sulfonamides synthesized via a direct sulfochlorination of 3- and 4-(hetero)arylisoxazol-5-amine scaffolds
摘要:
Three distinct series of isoxazole-based primary mono- and bis-sulfonamides have been synthesized via direct sulfochlorination, each of them delivering nanomolar inhibitors of human carbonic anhydrase. Certain pronounced SAR trends have been established and rationalized by in silico docking. These findings expand the structure-activity knowledge base for heterocycle-containing sulfonamide carbonic anhydrase inhibitors and further validate the power of direct electrophilic sulfochlorination as a means of introducing the pharmacophoric primary sulfonamide group into structurally diverse aromatic precursors.

An asymmetric Friedel–Crafts hydroxyalkylation reaction of 5-aminoisoxazoles with pyrazole-4,5-diones was developed under the catalysis of 5% chiral copper complexes. This reaction exhibits functional group tolerance and excellent enantioselectivity. Moreover, the reaction can be scaled up and its mechanism was studied.
efficient catalytic asymmetric Michael-type reaction of azonaphthalenes with 5-aminoisoxazoles has been developed. The reaction was based on the utilization of a chiralphosphoricacid as the catalyst, delivering a large panel of axiallychiral heterobiaryl diamines in generally good yields with excellent enantioselectivities. The gram-scale reaction and postmodification of the chiral product demonstrated
