LDL receptor gene expression promoters containing a 1,2,4-triazine derivative of the formula (I): ##STR1## wherein R.sup.1 is optionally substituted phenyl or heterocycle; R.sup.2 is optionally substituted phenyl, naphthyl, aralkyl, 5- or 6-membered aromatic heterocycle, alkyl, or alkenyl; X is O, S or NR.sup.4 ; R.sup.3 is optionally substituted phenyl, naphthyl, aralkyl, 5- to 6-membered aromatic heterocycle, alkyl, cycloalkyl or alkenyl, provided that when X is NR.sup.4, then it may form an optionally substituted nitrogen-containing heterocycle, or a pharmaceutically acceptable salt thereof, which can increase the expression dose (the amount of mRNA) of LDL receptor gene, and thus increase the amount of LDL receptor, and reduce the serum cholesterol level, and are useful in the treatment of hyperlipidemia.
含有1,2,4-三嗪衍生物的LDL受体基因表达启动子,其公式为(I):##STR1## 其中R.sup.1是可选取代的苯基或杂环;R.sup.2是可选取代的苯基、萘基、芳基烷基、5-或6-成员芳香杂环、烷基或烯基;X是O、S或NR.sup.4;R.sup.3是可选取代的苯基、萘基、芳基烷基、5-到6-成员芳香杂环、烷基、环烷基或烯基,但当X为NR.sup.4时,它可以形成可选取代的含氮杂环,或其药学上可接受的盐,可增加LDL受体基因的表达剂量(mRNA的量),从而增加LDL受体的数量,降低血清胆固醇水平,并有助于治疗高脂血症。
