Single-step synthesis of kyotorphin in frozen solutions by chymotrypsin
摘要:
A novel method of Kyotorphin (H-Tyr-Arg-OH) synthesis without protecting and deprotecting procedures is described -alpha-chymotrypsin-catalyzed aminolysis of H-Tyr-OEt by H-Arg-OH in frozen mixtures. In this one-step process yields of the peptide product above 80% have been obtained.
