  Synthesis and pharmacological activity of 1,3,6-trisubstituted-4-oxo-1,4-dihydroquinoline-2-carboxylic acids as selective ETA antagonists

  摘要：

  A series of 1,3,6-trisubsituted-4-oxo-1,4-dihyroquinoline-2-carboxylic acid analogs (2a-m) were designed and synthesized and their pharmacological activity determined, with the objective to better understand their SAR as potential ETA selective inhibitors. Most of the compounds displayed significant ETA antagonist activity having IC50 for inhibition of binding of the [I-125] ET-1 to ETA receptor < 10 nM, with good selectivity for ETA antagonism over ETB receptor. Based on the in vitro results, SAR of this series of compounds requires an alkoxy substituent at the 6-position to be a straight and saturated chain up to three carbons long, since substitution of unsaturated and branched alkyloxy groups results in decrease in ETA antagonist activity. In this series, compound 2c (6-O-n-propyl analog) was found to be most potent (IC50 = 0.11 nM) with ETB/ETA selectivity of 8303. (C) 2010 Elsevier Ltd. All rights reserved.
