The present invention relates to a compound represented by the following formula (1):
[wherein, X1 represents a carboxyl group which may be esterified or the like group;
Y1 represents a single bond, -O- or -N(R1)-;
at least one of A1, A2 and A3 is a group represented by the following formula (2): -R2-a1-R3-a2 →wherein, R2 represents a divalent C2-12 hydrocarbon group, R3 represents a single bond or a divalent C1-12 hydrocarbon group, a1 and a2 individually represent a single bond, -S-, -SO-, -SO2-, -SO2NH-, -O-, -N(R4)-, -CON(R5)-, -C(=O)- or - Si(R6)(R7)- and → means bonding with Q1, Q2 or Q3}, the remaining one or two of A1, A2 and A3 are the same or different and each independently represents a group represented by the following formula (3): -R8-a3-R9-a4 →wherein, R8 and R9 individually represent a single bond or a divalent C1-12 hydrocarbon group, a3 and a4 individually represent a single bond, -S-, -SO-, -SO2-, -SO2NH-, -O-, - N(R10)-, -CON(R11)-, -C(=O)- or -SI(R12)(R13)- and → means bonding with Q1, Q2 or Q3},;
at least one of Q1, Q2 and Q3 represents a cyclic hydrocarbon group or heterocyclic group and the remaining one or two of Q1, Q2 and Q3 individually represent a hydrogen atom, a carboxyl group which may be esterified, a hydrocarbon group or a heterocyclic group] or salt thereof; and a pharmaceutical comprising the same as an effective ingredient. The compound exhibits strong squalene synthetase inhibitory action and is therefore useful as a pharmaceutical for the treatment·prevention of hypercholesterolemia, hyperlipemia or arteriosclerosis.
本发明涉及一种由以下式(1)表示的化合物:[其中,X1代表可能酯化或类似基团的羧基;Y1代表单键,-O-或-N(R1)-;A1、A2和A3中至少有一个是由以下式(2)表示的基团:-R2-a1-R3-a2 →其中,R2代表二价的C2-12碳氢基团,R3代表单键或二价的C1-12碳氢基团,a1和a2分别代表单键,-S-,-SO-,-SO2-,-SO2NH-,-O-,-N(R4)-,-CON(R5)-,-C(=O)-或-Si(R6)(R7)-,→表示与Q1、Q2或Q3结合},A1、A2和A3中剩余的一个或两个是相同或不同的,并且每个独立地表示由以下式(3)表示的基团:-R8-a3-R9-a4 →其中,R8和R9分别代表单键或二价的C1-12碳氢基团,a3和a4分别代表单键,-S-,-SO-,-SO2-,-SO2NH-,-O-,-N(R10)-,-CON(R11)-,-C(=O)-或-SI(R12)(R13)-,→表示与Q1、Q2或Q3结合};Q1、Q2和Q3中至少有一个代表环烃基或杂环烃基,剩余的一个或两个分别代表氢原子,可能酯化的羧基,碳氢基团或杂环烃基的其中一个或两个]或其盐;以及包括其作为有效成分的药物。该化合物表现出强烈的角鲨烯合酶抑制作用,因此可用作治疗高胆固醇血症、高脂血症或动脉硬化的药物。
