Imidazoles of formula (I)
wherein A is a chemical bond or a straight or branched, saturated or unsaturated, aliphatic residue having from 1 to 6 carbon atoms, optionally substituted and/or optionally including 1, 2 or3 heteroatoms selected from oxygen, sulphur and nitrogen providing (in the case of 2 or 3 heteroatoms) that any such heteroatom is not located adjacent to a further such heteroatom or heteroatoms, the total number of said carbon atoms and heteroatoms not exceeding 6.
R is a fused, saturated or unsaturated, non-aromatic carbocyclic, bi- or tri-cyclic ring system providing that when R is a 9- decahydronaphthyl group, A does not represent a carbonyl group, a saturated or unsaturated, carbocyclic spirocyclic ring system, optionally containing one or more ring heteroatoms selected from oxygen, sulphur and nitrogen; or a saturated or unsaturated. carbocyclic bridged-polycyclic ring system, optionally containing one or more ring heteroatoms selected from oxygen, sulphur and nitrogen and having one or more bridges providing that when R is an adamantanyl group, A does not represent an ethylene radical (-(CH2)2-) substituted at the carbon atom a to the adamantanyl group by a hydroxy, oxo, ether or thioether grouping; or AR together represent a straight or branched, saturated or unsaturated, aliphatic residue having 3 to 6 carbon atoms, optionally substituted and/or optionally including 1, 2 or 3 heteroatoms selected from oxygen, sulphur and nitrogen providing (in the case of 2 or 3 heteroatoms) that any such heteroatom is not located adjacent to a further such heteroatom or heteroatoms, the total number of said carbon and heteroatoms not exceeding 6; which aliphatic residue is substituted by at least two groups, which may be the same or different, selected from the groups specified for R above and acid addition salts and pharmaceutically acceptable bioprecursors thereof.
Methods of preparing the imidazoles are disclosed
The imidazoles and their acid addition salts an bioprecur. sors are useful in the treatment of prophylaxis of thrombo- embolic conditions.
式(I)的咪唑
其中 A 是化学键或直链或支链、饱和或不饱和、脂肪族残基,具有 1 至 6 个碳原子,任选被取代和/或任选包括 1、2 或 3 个选自氧、硫和氮的杂原子,条件是(在 2 或 3 个杂原子的情况下)任何此类杂原子不与另一个或多个此类杂原子相邻,所述碳原子和杂原子的总数不超过 6。
R 是融合的、饱和或不饱和的、非芳香族碳环、双环或三环的环系统,但当 R 是 9-十氢萘基时,A 不代表羰基、饱和或不饱和的碳环螺环系统,可选地含有一个或多个选自氧、硫和氮的环杂原子;或饱和或不饱和的碳环桥聚环系统。(b) 碳环桥式多环环系统,可选择含有一个或多个选自氧、硫和氮的环杂原子,并 具有一个或多个桥,条件是当 R 为金刚烷基时,A 不代表在金刚烷基的碳原子 a 处被羟基、氧代、醚或硫醚基团取代的乙烯基 (-(CH2)2-);或 AR 共同代表直链或支链、饱和或不饱和、具有 3 至 6 个碳原子的脂族残基,可选被取代和/或可选包括 1、2 或 3 个选自氧、硫和氮的杂原子,前提是(在 2 或 3 个杂原子的情况下)任何此类杂原子不与另一个或多个此类杂原子相邻,所述碳原子和杂原子的总数不超过 6;该脂肪族残基被至少两个基团取代,这两个基团可以相同或不同,选自上述 R 所指的基团及其酸加成盐和药学上可接受的生物前体。
已公开咪唑的制备方法
咪唑类及其酸加成盐和生物前体可用于血栓栓塞的预防治疗。
