Compounds which are inhibitors of cholesterol biosynthesis (by inhibiting de novo squalene biosynthesis), and thus are useful as hypocholesterolemic agents and anti atherosclerotic agents are provided which have the structure
wherein m is 1, 2 or 3; n is 0, 1, 2 or 3;
Y1 and Y2 are H or halogen;
R2, R3 and R4 may be the same or different and are independently H, metal ion, C1 to Cs alkyl or C3 to C12 alkenyl;
X is O, S, NH or NCH2R15 wherein R15 is H or C1 to C5 alkyl; and
R1 is R5-Q1-Q2-Q3- wherein Q1, Q2 and Q3 are the same or different and are independently
or a single bond, with the proviso that if Q1 is a bond, then Q2 and Q3 are bonds and if Q2 is a bond, then Q3 is a bond, and wherein R6 is H, alkyl, halo, or haloalkyl, R7 is H, halo, alkyl or alkylthio; R8 is H, halogen, trimethylsilyl or lower alkyl; R9 is H or lower alkyl-;
R16-C≡C-CH2- (wherein R16 is H or lower alkyl) or CH3(CH2)p where p is an integer from 2 to 7; R10, and R" are the same or different and are independently H, lower alkyl, halogen, haloalkyl or lower alkenyl or R10 and R11 can be taken together to form (CH2)s where s is an integer from 2 to 7; and R13 an R14 are the same or different and are independently lower alkyl, with the proviso that if all of Q1, Q2 and Q3 are bonds, then both R10 and R" cannot be H and R5 cannot be alkyl(CH2)P- with p≦4; including all stereoisomers thereof.
New intermediates, new methods of preparation and a method for using such compounds to inhibit cholesterol biosynthesis are also provided.
所提供的化合物是胆固醇生物合成的抑制剂(通过抑制角鲨烯的从头生物合成),因此可用作降胆固醇药和抗动脉粥样硬化药,其结构为
其中 m 为 1、2 或 3;n 为 0、1、2 或 3;
Y1 和 Y2 是 H 或卤素;
R2、R3 和 R4 可以相同或不同,且独立地为 H、金属离子、C1 至 Cs 烷基或 C3 至 C12 烯基;
X 是 O、S、NH 或 NCH2R15,其中 R15 是 H 或 C1 至 C5 烷基;以及
R1 是 R5-Q1-Q2-Q3-,其中 Q1、Q2 和 Q3 相同或不同,且各自独立
或单键,但如果 Q1 是键,则 Q2 和 Q3 是键,如果 Q2 是键,则 Q3 是键,其中 R6 是 H、烷基、卤代或卤代烷基,R7 是 H、卤代、烷基或硫代烷基;R8 是 H、卤素、三甲基硅基或低级烷基;R9 是 H 或低级烷基-;
R16-C≡C-CH2-(其中 R16 是 H 或低级烷基)或 CH3(CH2)p,其中 p 是 2 至 7 的整数;R10 和 R "相同或不同,且独立地是 H、低级烷基、卤素、卤代烷基或低级烯基,或 R10 和 R11 可合并形成 (CH2)s,其中 s 是 2 至 7 的整数;R13 和 R14 相同或不同,且独立地为低级烷基,但如果 Q1、Q2 和 Q3 全部为键,则 R10 和 R" 不能为 H,R5 不能为 p≦4 的烷基(CH2)P-;包括其所有立体异构体。
此外,还提供了新的中间体、新的制备方法以及使用此类化合物抑制胆固醇生物合成的方法。
