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.
15-氧化甾醇具有抑制甲烷酸生物合成的能力,并产生其他效应,源自它们抑制甲烷酸生物合成的能力。15-氧化甾醇对应于以下结构式:其中:R.sub.1为--OH,.dbd.O,--OR.sub.4,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R.sub.3为.alpha.H,.beta.H,或.alpha.C.sub.1至C.sub.6烷基基团;R.sub.r为C.sub.1至C.sub.6烷基基团,最好是C.sub.1至C.sub.3烷基基团;R.sub.5为C.sub.1至C.sub.20脂肪基团,取代的C.sub.1至C.sub.20脂肪基团,或苯基团;n为2至6的整数,最好为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取代基可能在多个立体位置时,它们可以位于α或β位置。当然,基本甾醇结构可能包含不会对化合物的性质产生不利影响的取代基,这些取代基位于R.sub.1,R.sub.2和R.sub.3之外的位置。
