, and pharmaceutical uses therefor. This compound exhibits relatively high transcription activity as well as pronounced activity in arresting the proliferation of undifferentiated cells and inducing their differentiation to the monocyte thus evidencing use as an anti-cancer agent and for the treatment of skin diseases such as psoriasis as well as skin conditions such as wrinkles, slack skin, dry skin and insufficient sebum secretion. This compound also shows low activity in vivo on bone calcium mobilization, and therefore may be used to treat autoimmune disorders or inflammatory diseases in humans as well as renal osteodystrophy. This compound may also be used for the treatment or prevention of obesity.
Cyclopropane-containing vitamin D analogs of formulas I and IV are provided. Such compounds may be used in preparing pharmaceutical compositions and are useful in treating a variety of biological conditions.

Inhoffen-Lythgoe diol is described for the first time. As an application, the syntheses of 1α, 18,25-trihydroxyvitamin D3 (2, dienyne route) and 18,25-dihydroxyvitamin D3 (3, Wittig-Horner approach) are described. The synthetic strategy allows further functionalization of the hormone 1α,25-dihydroxyvitamin D3 at C-18.
