  Optimization of Alkylidene Hydrazide Based Human Glucagon Receptor Antagonists. Discovery of the Highly Potent and Orally Available 3-Cyano-4-hydroxybenzoic Acid [1-(2,3,5,6-Tetramethylbenzyl)-1H-indol-4-ylmethylene]hydrazide

  摘要：

  Highly potent human glucagon receptor (hGluR) antagonists have been prepared employing both medicinal chemistry and targeted libraries based on modification of the core (proximal) dimethoxyphenyl group, the benzyl ether linkage, as well as the (distal) benzylic aryl group of the lead 2, 3-eyano-4-hydroxybenzoic acid (3,5-dimethoxy-4-isopropylbenzyloxybenzylidene)hydrazide. Electron-rich proximal aryl moieties such as mono- and dimethoxy benzenes, naphthalenes, and indoles were found to be active. The SAR was found to be quite insensitive regarding the linkage to the distal aryl group, since long and short as well as polar and apolar linkers gave highly potent compounds. The presence of a distal aryl group was not crucial for obtaining high binding affinity to the hGluR. In many cases, however, the affinity could be further optimized with substituted distal aryl groups. Representative compounds have been tested for in vitro metabolism, and structure-metabolism relationships are described. These efforts lead to the discovery of 74, NNC 25-2504, 3-cyano-4-hydroxybenzoic acid [1-(2,3,5,6-tetramethylbenzyl)-1H-indol-4-ylmethylenelhydrazide, with low in vitro metabolic turnover. 74 was a highly potent noncompetitive antagonist of the human glucagon receptor (IC50 = 2.3 nM, K-B = 760 pM) and of the isolated rat receptor IC50 = 430 pM, K-B = 380 pM). Glucagon-stimulated glucose production from isolated primary rat hepatocytes was inhibited competitively by 74 (K-i = 14 nM). This compound was orally available in dogs (F-po = 15%) and was active in a glucagon-challenged rat model of hyperglucagonemia and hyperglycemia.

  Human glucagon receptor antagonists based on alkylidene hydrazides

  摘要：

  A series of alkylidene hydrazide derivatives containing an alkoxyaryl moiety was optimized. The resulting hydrazide-ethers were competitive antagonists at the human glucagon receptor. Pharmacokinetic experiments showed fast clearance of most of the compounds tested. A representative compound [4-hydroxy-3-cyanobenzoic acid (4-isopropylbenzyloxy-3,5-dimethoxy-methylene)hydrazide] with an IC50 value of 20 nM was shown to reduce blood glucose levels in fasted rats.
