A quinuclidine derivative represented by the following general formula (I), a pharmaceutically acceptable salt thereof, a hydrate thereof or a solvate thereof, which has strong squalene synthase inhibiting activity and is useful as a cholesterol lowering agent without causing side effects.
(Symbols in the formula represent the following meanings;
R1: a hydrogen atom, a halogen atom or a lower alkyl group,
R2: a hydrogen atom, a hydroxyl group or a lower alkoxy group,
: a single bond or a double bond, with the proviso that R2 does not exist when is a double bond,
X and Y: the same or different from each other and each represents a bond, an oxygen atom (-O-), a carbonyl group (-CO-), a group represented by the formula -S(O)p- or a group represented by the formula -NR3-,
p: 0, 1 or 2,
R3: a hydrogen atom or a lower alkyl group which may have a substituent,
A: a saturated or unsaturated lower alkylene group, a group of the formula -(CH2)mZ(CH2)n- or a group of the formula -(CH2)mZ(CH2)nCR4=,
Z: an oxygen atom (-O-), a group of the formula -S(O)q-, a carbonyl group (-CO-) or a group of the formula -NR5-,
R4: a hydrogen atom, a halogen atom or a lower alkyl group,
R5: a hydrogen atom or a lower alkyl group,
m and n: the same or different from each other and each is 0 or an integer of 1 to 5,
m + n: an integer of 1 to 5
q: 0, 1 or 2,
with the proviso that, when either one of X and Y is a bond, A is a group represented by the formula -(CH2)mZ(CH2)nCR4=.)

(式中符号代表以下含义;
R1:氢原子、卤素原子或低级烷基、
R2:氢原子、羟基或低级烷氧基、
R2:单键或双键,但 R2 为双键时不存在、
X和Y:彼此相同或不同,各自代表一个键、一个氧原子(-O-)、一个羰基(-CO-)、一个由式-S(O)p-代表的基团或一个由式-NR3-代表的基团、
p:0、1 或 2、
R3:氢原子或可带有取代基的低级烷基、
A:饱和或不饱和低级亚烷基、式-(CH2)mZ(CH2)n-或式-(CH2)mZ(CH2)nCR4=的基团、
Z:氧原子(-O-)、式-S(O)q-的基团、羰基(-CO-)或式-NR5-的基团、
R4:氢原子、卤素原子或低级烷基、
R5:氢原子或低级烷基、
m 和 n:相同或互不相同,各自为 0 或 1 至 5 的整数、
m+n:1 至 5 的整数
q:0、1 或 2、
但条件是,当 X 和 Y 中任何一个是键时,A 是由式-(CH2)mZ(CH2)nCR4=代表的基团。)
