The invention relates to derivatives and metabolites of ambrisentan, including compounds of general Formula (I) or salts, hydrates, solvates, racemates, or optical isomers thereof, wherein R
1
is —H or —OCH
3
; R
2
is —H, lower alkyl (e.g. C
1
-C
4
alkyl) or glycosidyl; and R
3
and R
4
are independently —CH3, —C(O)H or —CH
2
OR
6
, wherein R
6
is —H or a hydrocarbyl group having 1 to 20 carbon atoms. In some embodiments, compounds of Formula (I) exhibit selective affinity for ET
A
receptors and serve as endothelin receptor antagonists. In some embodiments, the compounds correspond to metabolites of ambrisentan produced by the enzymatic action of cytochrome P450 or uridine diphosphate glucuronosyl transferase enzymes, for example as elucidated in pre-clinical or clinical studies.
本发明涉及ambrisentan的衍生物和代谢物,包括一般式(I)的化合物或其盐、水合物、溶剂合物、外消旋体或光学异构体,其中R1为-H或-OCH3;R2为-H、较低的烷基(例如C1-C4烷基)或葡萄糖苷基;R3和R4独立地为-CH3、-C(O)H或-CH2OR6,其中R6为-H或具有1到20个碳原子的烃基。在某些实施例中,式(I)的化合物表现出对ETA受体的选择性亲和力,并作为内皮素受体拮抗剂。在某些实施例中,这些化合物对应于通过细胞色素P450或尿苷二磷酸葡糖醛酸转移酶酶的催化作用产生的ambrisentan的代谢物,例如在临床前或临床研究中阐明的代谢物。
