15-oxygenated sterols, having the ability to inhibit the biosynthesis of mevalonic acid, and produce other effects derived from their ability to inhibit the biosynthesis of mevalonic acid, are disclosed. The 15-oxygenated sterols correspond to the structural formula: ##STR1## where: R.sub.1 is --OH, .dbd.O, --OR.sub.4, ##STR2## a sulfate group, or a Mg, Na, or K salt of a sulfate group; R.sub.2 is --OH, .dbd.O, or ##STR3## R.sub.3 is .alpha.H, .beta.H, or an .alpha.C.sub.1 to C.sub.6 alkyl group; R.sub.r is a C.sub.1 to C.sub.6 alkyl group and preferably a C.sub.1 to C.sub.3 alkyl group; R.sub.5 is a C.sub.1 to C.sub.20 aliphatic group, a substituted C.sub.1 to C.sub.20 aliphatic group, or a phenyl group; and n is a whole number from 2 to 6 and preferably from 2 to 4. The basic ring structure may be saturated or unsaturated, and when it is possible for the R.sub.1 and R.sub.2 substituents to be in more than one steric position, they may be in either the .alpha. or .beta. position. It is of course understood that the basic sterol structure may contain substituents that do not adversely effect the properties of the compound at positions other than those of R.sub.1, R.sub.2, and R.sub.3.
本发明涉及15-氧化甾醇,其具有抑制甲烷酸生物合成的能力,并产生其他源自其抑制甲烷酸生物合成能力的效应。这些15-氧化甾醇对应于结构式:##STR1## 其中:R.sub.1为--OH,.dbd.O,--OR.sub.4,##STR2## 硫酸盐基团,或硫酸盐基团的Mg、Na或K盐;R.sub.2为--OH,.dbd.O或##STR3## R.sub.3为.alpha.H,.beta.H或.alpha.C.sub.1至C.sub.6烷基;R.sub.r为C.sub.1至C.sub.6烷基,优选为C.sub.1至C.sub.3烷基;R.sub.5为C.sub.1至C.sub.20脂肪族基、取代的C.sub.1至C.sub.20脂肪族基或苯基;n为2至6的整数,优选为2至4。基本环结构可以是饱和的或不饱和的,当R.sub.1和R.sub.2取代基可以处于多个立体位时,它们可以处于.alpha.或.beta.位置。当然,基本甾醇结构可能包含在R.sub.1、R.sub.2和R.sub.3以外的位置不会对化合物性质产生不良影响的取代基。
