Compounds represented by general formula (I), salts thereof, or hydrates of both, useful as excellent squalene synthase inhibitors wherein R1 is hydrogen or hydroxyl; HAr is an optionally substituted aromatic heterocycle; Ar is an optionally substituted aromatic ring; W is (1) a -CH¿2?-CH2- group which may be substituted, (2) a -CH=CH- group which may be substituted, (3) -C C-, (4) -NH-CO-, or the like; and X is a single bond, optionally substituted C1-6 alkylene, (5) -Q- [wherein Q is oxygen, sulfur, CO, or N(R?2¿) (wherein R2 is C¿1-6? alkyl or C1-6 alkoxy)], (6) -NH-CO-, or the like.
摘要:
A compound having excellent squalene synthetase inhibitory activity. It is a compound (I) represented by the following general formula, a salt thereof, or a hydrate of either. (I) In the formula, R1 means optionally substituted vinyl or an optionally substituted aromatic ring; n is an integer of 0 to 2; X, Y, and Z are the same or different and each means optionally substituted carbon, nitrogen, etc.; CyA means an optionally substituted 5- to 14-membered nonaromatic cyclic amino group optionally containing oxygen or sulfur; W means -C=C-, etc.; and A means a group of the formula (II) (wherein R8 represents hydrogen, hydroxy, etc.; B2 represents optionally substituted carbon or nitrogen; and c is 0 or 1), etc.
