J Control Release 2009; 142:206-13. [PMID: 19900495 DOI: 10.1016/j.jconrel.2009.10.025] [Citation(s) in RCA: 48] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2009] [Revised: 09/14/2009] [Accepted: 10/27/2009] [Indexed: 01/09/2023]
Abstract
Alterations in the physicochemical characteristics of peptide drugs can transform their biological and pharmaceutical features. In the present study, we explored the potentials of lithocholic acid (LCA)-modified exendin-4 derivatives as novel long-acting GLP-1 receptor agonists. Exendin-4 was modified with lithocholic acid at two lysine residues to produce three derivatives that were obtained by reverse-phase HPLC separation, namely, Lys(12)-LCA-exendin-4 (LCA-M2), Lys(27)-LCA-exendin-4 (LCA-M1), and Lys(12,27)-LCA-exendin-4 (LCA-Di)). The biological, pharmacological, and physicochemical characteristics of these three exendin-4 analogues were then investigated. Although slight reductions in the GLP-1 receptor binding capacity and insulinotropic activity of exendin-4 were observed after derivatization, the mono-LCA substitutions, especially LCA-M1, well-preserved antidiabetic activity in type 2 diabetic mice when administered subcutaneously or intraperitoneally. Furthermore, the pharmacokinetic characteristics were dramatically enhanced, that is, absorption was delayed and elimination half-life was increased (1.6+/-0.4 and 9.7+/-1.4h by exendin-4 and LCA-M1, respectively). The enhanced long-acting characteristics of the derivative was found to be due to albumin binding and nanoparticle formation, and these were verified by the restoration of normoglycemia in type 2 diabetic mice after single injection (>24h, >10 nmol/kg, s.c.) and daily injections (15 nmol/kg/day) maintained normoglycemia for the 4-week administration period. Furthermore, antidiabetic potentials, such as, glucose clearance kinetics and percentage areas occupied by pancreatic beta-cells were also enhanced by long-term LCA-M1 administration. The present study demonstrates that the derivatization of exendin-4 with LCA offers a possible means of producing a long-acting GLP-1 receptor agonist.
