摘要:The present invention relates to methods and intermediates for chemical synthesis of polypeptides and proteins, and more particularly to methods and intermediates for chemically ligating a peptide fragment containing N-terminal N-methyl-cysteine (SEQ ID NO: 1) with another peptide fragment having C-terminal thioester to generate a β-(methylamino)-thioester intermediate that spontaneously rearranges to form an amide bond. Furthermore, the invention relates to methods of converting N-methyl-thiazolidine to N-methyl-cysteine (SEQ ID NO: 1) of polypeptides and proteins. The invention also relates to methods of synthesizing peptide-thioester from peptide-acid fluoride.

标题 :Universal one-pot and up-scalable synthesis of SERS encoded nanoparticles
发明人：PAZOS PÉREZ NICOLÃ?S; MIR DE SIMÓN BERNAT
权利人:MEDCOM ADVANCE S A; MEDCOM ADVANCE S A
摘要:The universal one-pot and up-scalable synthesis of SERS encoded nanoparticles relies on the controlled co-absorption of mercaptoundecanoic acid (MUA) and the Raman code on the metallic surfaces of the nanoparticles. In contrast to most of the reported procedures which typically involve complex steps, the present method has demonstrated to be an easy and fast one-pot approach for the production of SERS-encoded nanoparticles. This versatile strategy allows for the SERS codification of particles with every molecule with affinity toward the metal surface, independently of its chemical nature, as exemplified here in the fabrication of 31 different encoded particles using the same standard procedure. In addition to the easiness of preparation, scalability to the liter regime, stability in aqueous solutions including PBS and chemical diversity, our SERS-encoded particles show considerably higher optical efficiency than those fabricated by using PEG or PVP polymers.
