19-nor-vitamin D analogs having an additional dihydrofuran ring connecting the 1α-oxygen and carbon-2 of the A-ring of the analog, and pharmaceutical uses therefore, are described. These compounds exhibit selective in vitro and in vivo activities, making them therapeutic agents for the treatment or prophylaxis of autoimmune diseases, some types of cancers, secondary hyperparathyroidism, psoriasis, or other skin diseases.

19-nor-vitamin D analogs having an additional dihydrofuran ring connecting the 3β-oxygen and carbon-2 of the A-ring of the analog, and pharmaceutical uses therefore, are described. These compounds exhibit selective in vitro and in vivo activities, making them therapeutic agents for the treatment or prophylaxis of autoimmune diseases, some types of cancers, metabolic bone diseases, osteomalacia, osteopenia, secondary hyperparathyroidism, psoriasis, or other skin diseases.

reduced activity compared to the natural hormone 1, but the binding, differentiation, and transcriptional activities of analogue 5 are markedly higher than that of 4 constrained in the alpha-chair conformation. Surprisingly, in vivo tests in mice showed that the analogue 4 significantly increases serum calcium at dose levels similar to 1alpha,25-(OH)2D3. These seemingly discordant results are discussed
