Phosphinic peptide
WebPhosphinic acid peptides (phosphinic pseudopeptides) are peptide isosteres where one peptide bond is substituted by the nonhydrolysable phosphinate moiety -P(O)(OH)-CH2- or … Webfamily of pseudo-peptides, termed phosphinic peptides. The chemical structure of phosphinic peptides shares some features with that of intermediates formed during the hydrolysis of peptides by proteolytic enzymes (fig. 1). Based on this analogy, phosphinic peptides have been proposed to represent a source of synthetic protease in-hibitors [1–3].
