  Rapid, Continuous Solution-Phase Peptide Synthesis:  Application to Peptides of Pharmaceutical Interest

  摘要：

  The Fmoc/TAEA and Bsmoc/TAEA methods for the rapid, continuous solution synthesis of peptide segments are shown to be applicable to the gram-scale synthesis of short peptides as well as, for the first time, to the synthesis of a relatively long (22-mer) segment, (hPTH 13-34). In the latter case the crude product was of significantly greater purity than a sample obtained via a solid-phase protocol. The Bsmoc methodology was optimized by a new technique involving filtration of the growing partially deprotected peptide at each coupling-deprotection cycle through a short column of silica gel.

  Thioesters, thiocarbamates, thiocarbazates, semithiocarbazates, peptides, aza-amino acid conjugates, and azapeptides; and a chemoselective and site-specific functionalization protocol of protected thiocarbazates and semithiocarbazates are described. The protocol features the use of Mitsunobu reaction to alkylate specifically the nitrogen atom close to the acylthiol moiety with alcohols to produce protected mono-substituted thiocarbazates that can be stored for months, activated under mild conditions at low temperature using halonium reagents and integrated orthogonally to make substituted semicarbazides that can be used, e.g., as synthons in synthesis of aza-amino acid conjugates, azapeptides and other peptidomimetics. Methods for preparing and using ureases, carbazides, semicarbazides, beta-peptides, azapeptides, and other peptidomimetics and azapeptide conjugates, and uses of ureases, carbazides, semicarbazides, beta-peptides, azapeptides in drug discovery, diagnosis, inhibition, prevention and treatment of diseases are also described.
