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.

Therapeutic vitamin d conjugates

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

Insulin vitamin D conjugates

The invention provides non-hormonal vitamin D conjugated via the third carbon on the vitamin D backbone to parathyroid hormone (PTH) proteins that result in increased absorption, bioavailability or circulating half-life when compared to non-conjugated forms.

The invention provides carriers that enhance the absorption, half-life or bioavailability of therapeutic compounds. The carriers comprise targeting groups that bind the Vitamin D Binding protein (DBP), conjugation groups for coupling the targeting groups to the therapeutic compounds, and optionally scaffolding moieties.

Carriers for improved drug delivery

The invention provides non-hormonal vitamin D conjugated to therapeutic RNA compounds that result in the compounds having increased absorption, bioavailability or circulating half-life when compared to non-conjugated forms. The vitamin D targeting groups are coupled to the therapeutic RNA compounds via the third carbon on the vitamin D backbone.

RNAi vitamin D conjugates

The invention provides carriers that enhance the absorption, half-life or bioavailability of Ghrelin peptides. The carriers comprise targeting groups that bind the Vitamin D Binding protein (DBP), conjugation groups for coupling the targeting groups to the therapeutic compounds, and optionally scaffolding moieties.
