    • This invention relates to novel physiological oxysteroids and oxysteroid hormones which are C27 modified sterols, particularly derivatives of intermediates in cholesterol synthesis, including lanosterol, zymosterol and desmosterol, including C27 diol and C27 acid derivatives, as well as related compounds and analogs thereof. The invention relates to treatment of cholesterol-related conditions by modulating the rate of cholesterol synthesis or cholesterol metabolism by administration of the oxysteroids, analogs or antagonists thereof. Methods are provided for ameliorating, treating or preventing macular degeneration by administering an agent which stimulates the expression or activity of steroid sulphotransferase (SLUT2), particularly SLUT2B1b, or which stimulates the expression or activity of CYP27A1 or sterol 27-hydroxylase. Assays for identification of analogs, antagonists or modulators of the oxysteroids or of sterol 27-hydroxylase are provided.

    • This invention relates to cholesterol synthesis and to the accumulation and regulation of cholesterol levels in body tissue. More specifically, the invention provides that the compound 26-aminocholesterol, ##STR1## and analogs and derivatives thereof, exhibit biological activity as a potent inhibitor of cholesterol synthesis and/or cholesterol accumulation in body tissue. The compounds strongly inhibit of the enzyme HMGCoA reductase and low density lipoprotein accumulation by non-hepatic cells. Surprisingly, it has been discovered that 26-aminocholesterol is selective for fibroblast (plasma) cells, and has little or no effect on hepato (liver) cells. Therapeutic compounds according to the invention include substituted or unsubstituted sterols of the formula: ##STR2## wherein the carbon atoms at positions 5 and 6 of the sterol are one of saturated and unsaturated, R.sub.1 is one of a 3-hydroxyl group and a 3-keto group, R.sub.2 is one of a hydroxyl group and a keto group, and wherein at least one of R.sub.3, R.sub.4 and R.sub.5 is an amino group and the others are each selected from the group consisting of hydrogen and an amino group.
    • 本发明涉及胆固醇合成和身体组织中胆固醇水平的积累和调节。 更具体地说,本发明提供化合物26-氨基胆固醇及其类似物及其衍生物作为胆固醇合成和/或体内组织中胆固醇积聚的有效抑制剂具有生物活性。 该化合物强烈地抑制HMGCoA还原酶和非肝细胞的低密度脂蛋白积累。 令人吃惊的是,已经发现26-氨基胆固醇对成纤维细胞(血浆)细胞是选择性的,并且对肝细胞(肝)细胞几乎没有或没有影响。 根据本发明的治疗化合物包括具有下式的取代或未取代的甾醇:其中固醇的5和6位的碳原子是饱和和不饱和的之一,R 1是3-羟基和3- 酮基,R2是羟基和酮基之一,其中R3,R4和R5中的至少一个是氨基,其它各自选自氢和氨基。
