  Renin inhibitors. Synthesis of transition-state analog inhibitors containing phosphorus acid derivatives at the scissile bond

  摘要：

  The synthesis of five amino phosphorus derivatives, 1a-e, is described. The derivatives were incorporated into a series (18) of analogues of the 5-14 portion of angiotensinogen, in most cases at the scissile Leu-Val bond. The resultant compounds were tested in vitro for their ability to inhibit human plasma renin. Replacement of the scissile bond with the phosphinic analogue of Leu10-Val11 (1b) gave the most potent inhibitors, having IC50 = 7.5 x 10(-8) M for H-Pro-His-Pro-Phe-His-(1b)-Ile-His-Lys-OH and IC50 = 1.0 x 10(-7) M for Z-Arg-Arg-Pro-Phe-His-(1b)-Ile-His-NH2. The shorter phosphonic acid sequence Z-Pro-Phe-His-(1d) retained biological activity with an IC50 = 6.4 x 10(-6) M.

  Hybrid peptides endomorphin-2/DAMGO: Design, synthesis and biological evaluation

  摘要：

  Endomorphin-2 [Tyr-Pro-Phe-Phe-NH2] and DAMGO [Tyr-D-Ala-Gly-(N-Me)Phe-Gly-ol] are natural (EM2) and synthetic (DAMGO) opioid peptides both selective for mu opioid receptor with high analgesic activity. In this work we report synthesis, in vitro and in vivo biological evaluation of five new hybrid EM2/DAMGO analogues, with the aim to obtain compounds with high affinity at mu-opioid receptor, high activity in animal nociception tests (hot plate and tail flick) and improved enzymatic stability. Double N-methylation on both Phe residues and C-terminal ethanolamide led to analogue 6e, which possesses a good in vitro mu affinity (K-i(mu) = 34 nM), combined with a remarkable in vivo antinociceptive activity.

  formation remains a critical aspect of N‐methylated peptide synthesis. In this study, we synthesized a variety of dipeptides in high yields, without severe racemization, from equivalent amounts of amino acids. Highly reactive N‐methylimidazolium cation species were generated in situ to accelerate the amidation. The key to success was the addition of a strong Brønsted acid. The developed amidation enabled
