Abstract: Disclosed are methods of purifying the compound (22E)-(24R)-2-methylene-22-dehydro-1?,24,25-trihydroxy-19-nor-vitamin D3 to obtain the compound in crystalline form. The methods typically include the steps of dissolving (22E)-(24R)-2-methylene-22-dehydro-1?,24,25-trihydroxy-19-nor-vitamin D3 in a solvent comprising ethyl acetate and hexane to form a solution, allowing crystals of (22E)-(24R)-2-methylene-22-dehydro-1?,24,25-trihydroxy-19-nor-vitamin D3 to form and precipitate from the solution, and recovering the crystals of (22E)-(24R)-2-methylene-22-dehydro-1?,24,25-trihydroxy-19-nor-vitamin D3 from the solution.

Abstract: A method of treating an MS patient with homosalate, octyl salicylate, or a combination is disclosed.

Abstract: An oral dosage form comprising a single dose of 25-hydroxy-vitamin D3 sufficient to elevate the serum level in a human to a concentration in the range of 30 ng/ml to 200 ng/ml for at least 7 days and a pharmaceutically suitable oral carrier system, wherein subsequent single doses at least every 7 days are sufficient to sustain the serum level in a human to a concentration in the range of 30 ng/ml to 200 ng/ml at steady-state pharmacokinetics is disclosed.

Abstract: Disclosed are 1?,25-dihydroxy-24,24-difluoro-2-methylene-19-nor-vitamin D analogs and their pharmaceutical uses. These new vitamin D analogs are 19-nor-vitamin D analogs having two fluorine atom substitutions at the 24 position (C-24) in the side chain and optionally having a 2-methylene substituent.

Abstract: This invention discloses 2-methylene-(22E)-25-hexanoyl-24-oxo-26,27-cyclo-22-dehydro-19-nor-vitamin D analogs, and specifically 2-methylene-(22E)-25-hexanoyl-24-oxo-26,27-cyclo-22-dehydro-19-nor-1?-hydroxyvitamin D3, 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.

Abstract: A method of treating an MS patient with homosalate, octyl salicylate, or a combination is disclosed.
