Hormonal replacement therapy (HRT) has failed to provide a cardioprotective action in postmenopausal women, and thus alternative pharmacological approaches are required. The present study examined the therapeutic potential of the partial estrogen receptor agonist tamoxifen and the angiotensin II type-1 receptor antagonist irbesartan on the hemodynamic profile of ovariectomized (OVX) female Sprague–Dawley rats (9–11 weeks). Three weeks following ovariectomy, uterine atrophy was evident and body weight was increased as compared with sham-operated animals. Left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), and mean arterial pressure (MAP) were significantly increased in the OVX rats as compared with sham rats. One week following ovariectomy, rats were treated with either tamoxifen (10 mg kg–1 day–1) or irbesartan (40 mg kg–1 day–1) for a period of 2 weeks. The administration of tamoxifen to OVX rats partially reversed uterine atrophy and prevented body weight gain, albeit body weight remained significantly lower than in sham-operated animals. LVSP and LVEDP were normalized in the tamoxifen-treated OVX rats, whereas MAP remained elevated. Irbesartan partially reduced the body weight gain of the OVX rats and did not influence uterine atrophy. LVSP and MAP were normalized in irbesartan-treated OVX rats, whereas LVEDP remained elevated. These data demonstrate that irbesartan rather than tamoxifen was efficacious in normalizing MAP in the OVX rats without a secondary effect on the uterus.Key words: ovariectomy, hemodynamics, tamoxifen, AT1 receptor antagonists.

We report the discovery of a novel glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor dual agonist that shows balanced agonism towards both the incretin receptor. The dual agonism of GLP-1 and GIP receptor was achieved by replacing the tryptophan cage of exendin-4 with the C- terminal undecapeptide sequence of oxyntomodulin along with a single amino acid substitution from histidine to tyrosine at the amino terminus of the peptide. The structural modification places lysine 30 of the novel incretin agonist in frame with the corresponding lysine residue in the native GIP sequence. The novel incretin agonist, named I-M-150847, promotes robust glucose-stimulated insulin exocytosis in cultured pancreatic beta cells. Chronic administration of I-M-150847 to mice fed on the high-fat diet improves glucose tolerance, decreases food intake, decreases visceral adiposity and body weight gain demonstrating its therapeutic potential in ameliorating type 2 Diabetes and Obesity.

Background and purpose The incretin hormone, glucose-dependent insulinotropic polypeptide (GIP), secreted by the enteroendocrine K-cells in the proximal intestine, may regulate lipid metabolism and adiposity but its exact role in these processes is unclear. Experimental approach We characterized in vitro and in vivo antagonistic properties of a novel GIP analogue, mGIPAnt-1. We further assessed the in vivo pharmacokinetic profile of this antagonist, as well as its ability to affect high-fat diet (HFD)-induced body weight gain in ovariectomized mice during an 8-week treatment period. Key results mGIPAnt-1 showed competitive antagonistic properties to the GIP receptor (GIPR) in vitro as it inhibited GIP-induced cAMP accumulation in COS-7 cells. Furthermore, mGIPAnt-1 was capable of inhibiting GIP-induced glucoregulatory and insulinotropic effects in vivo and has a favourable pharmacokinetic profile with a half-life of 7.2 hours in C57Bl6 female mice. Finally, sub-chronic treatment with mGIPAnt-1 in ovariectomized HFD mice resulted in a reduction of body weight and fat mass. Conclusion and Implications mGIPAnt-1 successfully inhibited acute GIP-induced effects in vitro and in vivo and sub-chronically induces resistance to HFD-induced weight gain in ovariectomized mice. Our results support the development of GIP antagonists for the therapy of obesity.
