The invention provides compounds of the formula:
wherein R1 is aryl, heteroaryl, cycloalkyl or alkyl;
R2 is H, alkyl, nitro, C0
2
R7, CONR5R6 or halo;
R3 and R4 are H, NR5R6, NC(O)R7, halo, trifluromethyl, alkyl, CONR5R6, CO
2
R7, nitrile or alkoxy; R5 and R6 may be the same or different and may be H, alkyl, aryl, heteroaryl or cycloalkyl; or R5 and R6 may together form a saturated, unsaturated or partially saturated 4 to 7 member ring, wherein said ring may optionally comprise one or more further heteroatoms selected from N, O or S; R7 is H or alkyl; A is H, halo, or a group of formula X-L-Y; X is O, S or NR8; R8 is H or alkyl;
L is (CH
2
)
n
, where n is 0, 1, 2, 3 or 4; and Y is aryl, a heterocyclic group, alkyl, alkenyl or cycloalkyl; the products of mono- and di-oxidation of sulphur and/or mono-oxidation of nitrogen moieties in compounds of formula I; or a pharmaceutically acceptable salt thereof. These compounds find use as inhibitors of potassium ion channels and thus are useful in the treatment of various conditions including arrhythmia and type-2 diabetes mellitus.
本发明提供了以下化合物:
其中,R1为芳基、杂环芳基、环烷基或烷基;
R2为H、烷基、硝基、C02R7、CONR5R6或卤素;
R3和R4为H、NR5R6、NC(O)R7、卤素、三氟甲基、烷基、CONR5R6、CO2R7、腈或烷氧基;
R5和R6可以相同也可以不同,可以是H、烷基、芳基、杂环芳基或环烷基;或者R5和R6可以一起形成一个饱和、不饱和或部分饱和的4至7成员环,其中该环可以选择性地包含一个或多个进一步的杂原子,所选择的杂原子为N、O或S;
R7为H或烷基;
A为H、卤素或公式X-L-Y的基团;
X为O、S或NR8;
R8为H或烷基;
L为(CH2)n,其中n为0、1、2、3或4;
Y为芳基、杂环基、烷基、烯丙基或环烷基;
化合物I的硫单氧化物和/或氮单氧化物的单一和双重氧化产物;或其药学上可接受的盐。这些化合物可用作钾离子通道的抑制剂,因此可用于治疗包括心律失常和2型糖尿病在内的各种疾病。
