Design and synthesis of heterofunctional V1a-selective vasopressin receptor ligands with lysine at position 9
in Journal of Molecular EndocrinologyABSTRACT
A peptide analogue of [8-arginine]vasopressin (AVP) with Lys substituted for Gly at position 9 ([d(CH2)5Tyr(Me)2LysNH29]AVP; ALVP) has been synthesized as a precursor for the production of heterofunctional vasopressin receptor ligands. Three heterofunctional ligands have been prepared by attaching biotin and a photoreactive cross-linker capable of iodination, either alone or in combination, to the ε-amino group of Lys at position 9 in ALVP. The binding characteristics of these novel ligands have been determined at the V1a and V2 vasopressin receptors by employing membrane preparations of rat liver and kidney respectively. All of the analogues synthesized during the course of this study bound selectively, and with high affinity, to the V1a vasopressin receptor subtype. Our results demonstrate that the strategies described in this paper provide a convenient means of synthesizing heterofunctional vasopressin receptor ligands with preservation of subtype-specific, high affinity binding characteristics. These parameters establish the potential value of the analogues as probes for investigating V1a receptor structure and function.
Journal of Molecular Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
