The invention provides non-hormonal vitamin D conjugated to apelin proteins that result in increased absorption, bioavailability or circulating half-life when compared to non-conjugated forms. In some embodiments, the vitamin D targeting groups are coupled to the apelin proteins via the third carbon on the vitamin D backbone.

Therapeutic vitamin D conjugates

The invention provides a parathyroid hormone (PTH) compound comprising a PTH peptide. The PTH compound has a significantly increased bioavailability or circulating half-life when compared to a bioavailability or a circulating half-life of a native form of the PTH peptide. The PTH compound has a significantly greater serum concentration at multiple timepoints post-administration to a rat when compared to that of a native PTH peptide.
