  Synthesis, in vitro pharmacology and biodistribution studies of new PD 156707-derived ETA receptor radioligands

  摘要：

  It is assumed that the regulation of cardiac endothelin (ET) receptor density is abnormal in heart diseases. From that perspective, an ET receptor radioligand is needed to assess ET receptor density in vivo. The nonpeptidyl ETA receptor antagonist PD 169390 was labelled with radioiodine to give a putative radioligand for SPECT. Labelling with [I-125]iodide and [I-123]iodide was accomplished with good to excellent radiochemical yields. The affinities of the nonradioactive reference and those of selected precursor compounds for ETA receptors were determined, using [I-125]iodine labelled endothelin-1 with mouse ventricular membranes. All employed substances exhibited potent in vitro pharmacological characteristics with K-i values comparable to that of the lead compound PD 156707. Biodistribution studies and scintigraphic imaging experiments in mice, however, showed no significant uptake of the [I-123] derivative in the heart. (c) 2005 Elsevier Ltd. All rights reserved.

  Summary:  Knockout (KO) models have provided important insights into the function of many receptors and signalling molecules. However, analysis of endothelin (ET) receptor knockouts has been complicated by the development of lethal phenotypes. In this paper, we present our strategy for examining endothelin-B- (ETB) receptor function in the context of other strategies for rescuing the lethal phenotype of ETB knockout mice.

  摘要：基因敲除（KO）模型为了解许多受体和信号分子的功能提供了重要线索。然而，对内皮素（ET）受体基因敲除的分析因出现致死表型而变得复杂。在本文中，我们结合其他挽救 ETB 基因敲除小鼠致死表型的策略，介绍了我们研究内皮素-B（ETB）受体功能的策略。
