  Design, Synthesis, and Binding Affinities of Pyrrolinone-Based Somatostatin Mimetics

  摘要：

  Tetrapyrrolinone somatostatin (SRIF) mimetics (cf. 1), based on a heterochiral (D,L-Mixed) pyrrolinone scaffold, were designed, synthesized, and evaluated for biological activity. The iterative synthetic sequence, incorporating the requisite functionalized coded and noncoded amino acid side chains, comprised a longest linear synthetic sequence of 23 steps. Binding affinities at two somatostatin receptor subtypes (hsst 4 and 5) reveal micromolar activity, demonstrating that the D,L-Mixed pyrrolinone scaffold can be employed to generate functional mimetics of peptide beta-turns.
