Abstract

This invention discloses 3-desoxy-2-methylene-vitamin D analogs, and specifically (20S)-3-desoxy-1α,25-dihydroxy-2-methylene-vitamin D₃ and (20R)-3-desoxy-1α,25-dihydroxy-2-methylene-vitamin D₃ as well as pharmaceutical uses therefor. These compounds exhibit relatively high binding activity and pronounced activity in arresting the proliferation of undifferentiated cells and inducing their differentiation to monocytes thus evidencing use as anti-cancer agents especially for the treatment or prevention of osteosarcoma, leukemia, colon cancer, breast cancer, skin cancer or prostate cancer. These compounds also exhibit relatively high calcemic activity evidencing use in the treatment of bone diseases.
