This invention provides smooth muscle cell proliferation inhibitors of formula I having the structure
wherein
Y is C or N;
where n is 0-3;
X is
R1, and R2 are independently, hydrogen, alkyl of 1 to 6 carbon atoms, or halo, acetyl, phenyl, CF3, CN, OH, NO2, NH2, alkoxy of 1 to 6 carbon atoms, or cyanoalkoxy of 2 to 7 carbon atoms;
R3 is hydrogen, acylamide of 2 to 6 carbon atoms or alkoxy of 1 to 6 carbon atoms;
R4, R5, R6, R7, and R8 are each, independently, acyl of 1 to 6 carbon atoms, benzyl substituted with R1, and R2; or benzoyl substituted with R1 and R2;
R9 and R10 are each, independently, acyl of 1 to 6 carbon atoms, or the R9 and R10 groups on the 4′ and 6′ positions of the maltose may be taken together to form a cyclic acetal which may be substituted with alkyl of 1 to 6 carbon atoms, two alkyl groups each having 1 to 6 carbon atoms, pyridine substituted with R1, phenyl substituted with R1, benzyl substituted with R1, 2-phenylethyl substituted with R1, or 3-phenylpropyl substituted with R1;
with the provisio that when R1 or R2 are cyanoalkoxy of 2-7 carbon atoms, R3 is not acylamide, and further provided that when R1, R2, or R3 are alkoxy of 1-6 carbon atoms, at least one of R1, R2, R3, or R4 are not hydrogen;
or a pharmaceutically acceptable salt thereof.
这项发明提供了一种具有结构的平滑肌细胞增殖抑制剂,其中Y为C或N;n为0-3;X为R1,R2分别独立地为氢、1到6个碳原子的烷基、卤素、乙酰、苯基、三氟甲基、氰基、羟基、硝基、1到6个碳原子的烷氧基,或2到7个碳原子的氰基烷氧基;R3为氢、2到6个碳原子的酰胺基或1到6个碳原子的烷氧基;R4、R5、R6、R7和R8分别独立地为1到6个碳原子的酰基、用R1和R2取代的苄基,或用R1和R2取代的苯甲酰基;R9和R10分别独立地为1到6个碳原子的酰基,或在麦芽糖的4′和6′位置上的R9和R10基团可以结合在一起形成一个环状缩醛,该缩醛可以用1到6个碳原子的烷基、每个具有1到6个碳原子的两个烷基、用R1取代的吡啶、用R1取代的苯基、用R1取代的苄基、用R1取代的2-苯乙基或用R1取代的3-苯基丙基取代;条件是当R1或R2为2-7个碳原子的氰基烷氧基时,R3不是酰胺基,并且进一步规定当R1、R2或R3为1-6个碳原子的烷氧基时,R1、R2、R3或R4中至少有一个不是氢;或其药用可接受盐。
