Design and Synthesis of Novel Janus Dendrimers as Lipophilized Antioxidants
摘要:
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.
PEGYLATED LIPID COMPOUNDS AND METHODS OF USE THEREOF
摘要:
The present disclosure relates to PEGylated lipid compounds and pharmaceutically acceptable salts thereof. Such compounds are useful, for example, as constituent parts of lipid nanoparticle (LNP) formulations for delivery of various active agents. The present disclosure further provides LNPs comprising a disclosed compound. Also provided herein are methods of preparing such PEGylated lipid compounds, as well as pharmaceutical compositions comprising an LNP and an active agent; and methods of use thereof.
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.
