title: Endothelin receptor antagonists: synthesis and structure-activity relationships of substituted benzothiazine-1,1-dioxides.
abstract: The development of benzothiazine-1,1-dioxide derivatives as a new structural class of potent endothelin receptor antagonists is described. Structure-activity relationships (SAR) revealed that PD164800 (1) is a potent antagonist of the ETA receptor subtype.
