3,9-disubstituted-spiro[5.5]undecanes of formula (I):
wherein R represents hydrogen or an unsubstituted or substituted C2-C6 alkyl or C2-C6 alkenyl group,
n is an integer from 0 to 4
and Y is oxygen or sulphur; and the symbol means a single or double bond with the proviso that
(i) when is a single bond
A represents a C-H or C-ORI group, wherein R1 is H or CH3, and
B represents a substituted C1-C6 lower alkyl or C2-C6 alkenyl chain;
(ii) when is a double bond
A represents a carbon atom C and
B represents: a = N-NR2-C(=Z)NHR3 group, wherein R2 and R3 are hydrogen, C1-C6 lower alkyl, benzyl or phenyl, or R2 and R3, taken together with the nitrogen atoms, form an unsubstituted or substituted 5- or 6-membered ring, and Z is oxygen, sulphur or NR9, wherein R9 is H, C1-C4 lower alkyl, CN or taken together with R2 or R3 forms an unsubstituted or substituted monoheterocyclic 5-or 6-membered ring;
and their pharmaceutically acceptable salts. These compounds may be used for the preparation of a medicament for the treatment of cardiovascular disorders, hypertension and/or cardiac failure.
式 (I) 的 3,9-二取代螺[5.5]十一烷:
其中 R 代表氢或未取代或取代的 C2-C6 烷基或 C2-C6 烯基、
n 是 0 至 4 的整数
Y 是氧或硫;符号表示单键或双键,但有以下条件
(i) 当为单键时
A 代表 C-H 或 C-ORI 基团,其中 R1 是 H 或 CH3,以及
B 代表取代的 C1-C6 低级烷基或 C2-C6 烯基链;
(ii) 当为双键时
A 代表碳原子 C 和
B 代表:=N-NR2-C(=Z)NHR3 基团,其中 R2 和 R3 为氢、C1-C6 低级烷基、苄基或苯基,或 R2 和 R3 与氮原子一起形成未取代或取代的 5 或 6 元环,Z 为氧、硫或 NR9,其中 R9 为 H、C1-C4 低级烷基、CN 或与 R2 或 R3 一起形成未取代或取代的单杂环 5 或 6 元环;
及其药学上可接受的盐类。这些化合物可用于制备治疗心血管疾病、高血压和/或心力衰竭的药物。
