A photoremovable ligation auxiliary for use in polypeptide synthesis
摘要:
A photoremovable auxiliary for use in peptide synthesis via the native chemical ligation method is described. A 2-mercapto-1-(2-nitrophenyl)ethylamine (Mnpe-amine) moiety was attached to the N-terminus of a peptide via the periodate oxidation of a seryl peptide. The resulting peptide was then ligated to a peptide thioester, and UV (365 nm) irradiation resulted in the removal of the auxiliary from the peptide. (C) 2003 Elsevier Ltd. All rights reserved.
Synthesis and protein kinase C binding activity of benzolactam-V7
摘要:
Benzolactam-V7 (3a), a simplified analogues of (-)-indolactam-V with twist-form conformation, was synthesized and evaluated as a new protein kinase C modulator. Both 3a and its-7-substituted analogue 3c showed weak binding activity to displace PDBU binding from recombinant PKC alpha. (C) 1999 Elsevier Science Ltd. All rights reserved.
