Asymmetric synthesis of Boc- N -methyl- p -benzoyl-phenylalanine. preparation of a photoreactive antagonist of Substance P
摘要:
The asymmetric synthesis of (S)-Boc-N-methyl-p-benzoyl-phenylalanine was performed by alkylation of sultam Boc-sarcosinate. The levorotatory sultam led to (S)-Boc-N-methyl amino acids with high optical purity. This photoreactive amino acid was incorporated into the sequence of a Substance P peptide antagonist. Comparison of the affinity and antagonistic properties of Biotinyl-apa-[D-Pro(9), MePhe(pBz)(10), Trp(11)]SP for human tachykinin NK-1 receptor demonstrated that this photoreactive antagonist should be a suitable tool for photolabelling studies, (C) 1998 Elsevier Science Ltd.
