The chains and segments of unordered cationic polypeptides are complex and may produce unexpected biol. activities. Herein, the Ugi’s 4CC reaction is adopted to synthesize a cationic alternating copolymer comprising ornithine and glycine (poly(Orn-alter-Gly)) with an ordered sequence for enhanced bacterial resistance. In this technique, potassium isocyanate, 4-(N-carbobenzyloxyamino)-1-butyraldehyde and 1-(4-Methoxyphenyl)ethylamine react to produce MPE-substituted poly(Orn-alter-Gly) in one step without using a catalyst and then poly(Orn-alter-Gly) is obtained by removing the N-(1-p-methoxyphenethyl) (MPE) group. 1H NMR, Fourier transform IR spectroscopy, and automatic amino acid anal. confirm that ornithine and glycine are linked alternately in the poly(Orn-alter-Gly) chains. Both MPE-substituted poly(Orn-alter-Gly) and poly(Orn-alter-Gly) have excellent antibacterial activity against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa as well as excellent biocompatibility. The synthesis strategy and materials provide new information on how to obtain ordered sequence cationic polypeptides. In the experimental materials used by the author, we found 4-Aminobutan-1-ol(cas: 13325-10-5Related Products of 13325-10-5)
4-Aminobutan-1-ol(cas: 13325-10-5) is used in the synthesis of NSAIDs with anti-inflammatory properties. Also used in the synthesis of polyamine transport ligands with specificity against human cancers allowing easy access to specific cancer cells.Related Products of 13325-10-5
