Compounds of formula (I):
{wherein: R1 and R2 each represents a variety of organic groups; R3 and R4 each represents hydrogen or a variety of organic groups; A represents a group of formula (A-1):
[wherein: R5 represents hydrogen, hydroxy or alkyl, R6 represents hydroxy, alkoxy, alkylthio or an amine residue, X and Y each represents oxygen or sulfur, and Z represents a direct single bond between the nitrogen atom shown and the benzene ring shown in formula (I), or an alkylene group],
G represents a single bond, alkylene or substituted alkylene; the broken line represents a single or double bond; when the broken line represents a double bond, D represents a carbon atom; and E represents an ═N—O— group; when the broken line represents a single bond, D represents a CH group or a nitrogen atom, and E represents an oxygen atom, a sulfur atom, an —NH— group or a —CO— group}; and pharmaceutically acceptable salts, esters or other derivatives thereof have the ability to inhibit an ileal bile transporter and so may be used to treat or prevent hypercholesterolemia.
式(I)的化合物:
其中:R1和R2分别代表各种有机基团;R3和R4分别代表氢或各种有机基团;A代表式(A-1)的基团:
[其中:R5代表氢、羟基或烷基,R6代表羟基、烷氧基、烷基硫氧基或胺基残基,X和Y分别代表氧或硫,Z代表氮原子与式(I)中所示苯环之间的直接单键,或者是一个烷基链],
G代表单键、烷基或取代烷基;虚线代表单键或双键;当虚线代表双键时,D代表碳原子;E代表一个-N—O—基团;当虚线代表单键时,D代表一个CH基团或一个氮原子,E代表一个氧原子、硫原子、一个—NH—基团或一个—CO—基团;以及药学上可接受的盐、酯或其他衍生物具有抑制回肠胆汁转运蛋白的能力,因此可用于治疗或预防高胆固醇血症。
