Decomposition of Piloty's acid derivatives - Toward the understanding of factors controlling HNO release

摘要

The recent interest in the clinical applications of Piloty's acid derivatives as HNO donors for the treatment of cardiovascular system dysfunction has led us to the examination of factors controlling HNO release from selected ortho-substituted N-hydroxysulfonamides. Here we present the kinetic and quantum mechanical studies on the mechanism of HNO release from selected ortho-substituted N-hydroxysulfonamides and in vivo examination of the antiaggregatory properties of N-hydroxy-(2-bromobenzene)sulfonamide complex with sodium salt of beta-cyclodextrin sulfobutyl ethers-ethyl ethers as compared with Angeli's salt.
