Nonpeptide RGD antagonists: A novel class of mimetics, the 5,8-disubstituted 1-azabicyclo[5.2.0]nonan-2-one lactam
摘要:
The 1-azabicyclo[5.2.0]nonan-2-one lactam 1 adequately substituted on both cycles A and B as scaffolds mimics the conformationally constrained beta-turn of the tripeptide RGD signaling motif of fibronectin. Using an in vitro assay, we establish that trans diastereoisomer 1b dissociates a soluble fibronectin-integrin alpha(5)beta(1) complex at concentrations comparable to those of a linear RGDS peptide as a competitor.
