Synthesis, Antibacterial Activity and Cytotoxicity of Novel Janus Peptide Dendrimers
摘要:
In an attempt to find new antibacterial agents, a series of well-defined Janus peptide dendrimers, which feature multiple anionic groups and amphiphilic structure, were synthesized and characterized in detail. The antibacterial activities of all the synthesized dendrimers were tested and screened by using the two-fold serial dilution method. Several compounds showed activity against E. coli, S. aureus, methicillin-resistant S. aureus, and E. faecalis. Further cytotoxicity assays showed that the antibacterial dendrimers were nontoxic against HEK293.

In the search for better antioxidants with more satisfactory lipophilicity, a series of Janus dendrimers that consisted of gallic acid and alkyl chains as the peripheral groups, were designed and synthesized. These dendrimers take advantage of a dendritic display to carry multi-antioxidants and multi-lipophilic moieties simultaneously. Consequently, the resulting dendrimers, which showed satisfactory lipophilicity and better antioxidant activity than the gallic acid monomer, are potential novel lipophilized antioxidant agents.
