fertility and certain cancers. The endogenous ligands human chorionic gonadotropin (hCG) and LH bind to the large N terminal domain of the receptor. We recently reported on the first radiolabeled low molecular weight (LMW) agonist for this receptor, [3H]Org 43553, which was now used to screen for new LMW ligands. We identified a terphenyl derivative that inhibited [3H]Org 43553 binding to the receptor, which
黄体生成素(LH)受体在生育和某些癌症中起重要作用。人绒毛膜促性腺激素(hCG)和LH的内源性配体与受体的大N末端结构域结合。我们最近报道了该受体的第一种放射性标记的低分子量(LMW)激动剂,[ 3 H] Org 43553,目前已用于筛选新的LMW配体。我们鉴定出一种抑制[ 3 H] Org 43553与受体结合的三联苯衍生物,这使我们合成了许多衍生物。该三联苯系列中最有效的化合物24(LUF5771)能够将[ 3 H] Org 43553的解离速率提高3.3倍(在10μM下)。在功能测定中,存在24会导致Org 43553和LH的效能降低2至3倍。因此,本文提出的化合物是第一种变构抑制LH受体的LMW配体。
