Microginins, Zinc Metalloproteases Inhibitors from the Cyanobacterium Microcystis aeruginosa
摘要:
Eight new linear peptides, microginins 478 (1), 51-A (2), 51-B (3) and 91-A (4) to 91-E (8), congeners of mioroginin, were isolated from the cyanobacterium Microcystis aeruginosa. These structures were elucidated to be 1-8 on the basis of 2D NMR data and chemical degradation. These peptides inhibited aminopeptidase M (1, 2 and 6-8) and angiotensin-converting enzyme (1). Tnt: structure-activity relationship within a series of degradation and derivative products of microginin was investigated by the chemical studies. (C) 2000 Elsevier Science Ltd. All rights reserved.
Total synthesis of microginin, an angiotensin-converting enzyme inhibitory pentapeptide from the blue-green alga Microcystis aeruginosa
摘要:
Microginin, an angiotensin-converting enzyme inhibitory peptide isolated form the blue-green alga Microcystis aeruginosa, and its three diastereoisomers were efficiently synthesized, which unequivocally established the absolute stereostructure of microginin to be 1d.
