  • Patent number: 6013655
    Abstract: Methods, compositions, and compounds for modulating the activity of an endothelin pepuide are provided. The methods use compositions that contain compounds that include those of the formula: ##STR1## where X is selected from groups that include O, S, and NH; Y is selected from O.sup.+ and N, and R.sup.1 and R.sup.2 are each selected independently from among alkyl, lower allkenyl, lower alkynyl, lower haloalkyl, halide, pseudohalide or H, except that R.sup.2 is not halide. R.sup.3, R.sup.4 and R.sup.5 are selected from among groups that include hydrogen, halide, alkoxy, alkyl, haloalkyl; and R.sup.7 is selected from groups that include (CH.sub.2).sub.r R.sup.18, in which r is 0 to 6 and R.sup.18 is selected from groups that include aryl, particularly pyrimidinyl and phenyl.
