摘要:
A peptidic mimetic of RNA having a guanine-adenine-guanine code as a base sequence was prepared as a leading compound of Vero-toxin inhibitors. The synthesized hexapeptide is composed from two gamma-guanyl-beta-hydroxy-alpha-L-amino acids and one gamma-adenyl-beta-hydroxy-alpha-L-amino acid, which were prepared by using L-threonine aldolase-catalyzed reaction, in addition to three glycines. On designing this peptide, the beta-hydroxyl groups in the novel cc-amino acids are compared to the 2'-hydroxyl groups of RNA, and glycine was chosen as the mimic of the phosphate groups in the RNA backbone.
