A non-toxic biologically active compound is provided having the following general formula (I), wherein n is an integer from 1 to 14, preferably from 2 to 4, and R is an organic moiety, preferably a group different from but structurally substantially similar to 2-methyl naphthoquinone, or a group P-C(R1)-P, where each P stands for a -PO(OH)2 group and R1 is a (poly)isoprenyl group, hydroxy, halogen (preferably chloro or bromo), or hydrogen, or a pharmaceutically acceptable derivative thereof. These compounds are useful for the treatment or prevention of certain disorders in a mammal, especially a human being, for example postmenopausal loss of bone in women, juvenile or senile osteoporosis in men and women, cardiovascular calcification and other ectopic calcifications. |
