The asymmetric synthesis and in vitro characterization of succinyl mercaptoalcohol and mercaptoketone inhibitors of matrix metalloproteinases
摘要:
A series of succinyl based mercaptoketones and diastereomeric mercaptoalcohols were prepared and evaluated in vitro as inhibitors of the matrix metalloproteinases collagenase-1 (MMP-1), stromelysin (MMP-3), and gelatinase-B (MMP-9). (C) 1998 Elsevier Science Ltd. All rights reserved.
Development of Novel G-Protein-Coupled Receptor 54 Agonists with Resistance to Degradation by Matrix Metalloproteinase
摘要:
Kisspeptin-GPR54 signaling is involved in the suppression of cancer metastasis and regulation of hormonal secretion. Recently, matrix metalloproteinase mediated deactivation of kisspeptins through hydrolysis of the Gly-Leu peptide bond has been reported. In the present report, GPR54 agonistic peptides having several nonhydrolyzable Gly-Leu dipeptide isosteres were designed and synthesized. (E)-Alkene- and hydroxyethylene-type isostere-containing analogues maintained the original activity with higher stability in murine serum and resistance to MMP-9-mediated cleavage.
