Methods, compositions, and compounds for modulating the activity of an endothelin peptide are provided. The methods use compositions that contain compounds that include those of the formula:
1
where X is selected from groups that include O, S, and NH; Y is selected from O
+
and N, and R
1
and R
2
are each selected independently from among alkyl, lower alkenyl, lower alkynyl, lower haloalkyl, halide, pseudohalide or H, except that R
2
is not halide. R
3
, R
4
and R
5
are selected from among groups that include hydrogen, halide, alkoxy, alkyl, haloalkyl; and R
7
is selected from groups that include (CH
2
)
r
R
18
, in which r is 0 to 6 and R
18
is selected from groups that include aryl, particularly pyrimidinyl and phenyl. The methods are effected by contacting endothelin receptors with one or more of the compounds or with compositions containing one or more of the compounds prior to, simultaneously with, or subsequent to contacting the receptors with an endothelin peptide.
本发明提供了用于调节内皮素肽活性的方法、组合物和化合物。该方法使用包含下列公式1中化合物的组合物:其中X选自包括O、S和NH的基团;Y选自O+和N,R1和R2各自独立地选自烷基、较低烯基、较低炔基、较低卤代烷基、卤素、伪卤素或H,但R2不是卤素。R3、R4和R5选自包括氢、卤素、烷氧基、烷基、卤代烷基的基团;R7选自包括(
CH2)rR18的基团,其中r为0到6,R18选自包括芳基,特别是
嘧啶基和苯基的基团。该方法通过在与内皮素肽接触之前、同时或之后将内皮素受体与一个或多个化合物或包含一个或多个化合物的组合物接触来实现。
