  Hydroxamic Acids as Potent Inhibitors of Endothelin-Converting Enzyme from Human Bronchiolar Smooth Muscle

  摘要：

  Hydroxamic acids 6a-h, derived from malonyl amino acids, and 25a-d, derived from succinyl amino acids, were synthesized as inhibitors of human bronchiolar smooth muscle endothelin-converting enzyme (HBSM ECE). Several unexpected side reactions were discovered, particularly in the synthesis of hydroxamates derived from succinates. In vitro evaluation against human bronchiolar ECE revealed that in all cases hydroxamates derived from malonate were more potent than hydroxamates derived from succinate. Isopropyl and isobutyl P-1' side chains were suitable; omission of the P-1' Side chain seriously diminished potency. In the P-2' position, several amino acids gave potent malonate-derived hydroxamate inhibitors (6b,d-h, IC50 = 0.2-6.8 nM), and beta-Ala provided an extremely potent inhibitor (6c, IC50 = 0.01 nM). C-terminus carboxylates are much more potent ECE inhibitors than the corresponding amides. Most of the hydroxamates were also potent inhibitors of thermolysin and neutral endopeptidase (NEP); however, the P-2' beta-Ala derivative 6c uniquely inhibited HBSM ECE much more potently than NEP.
