A biodegradable amphiphilic poly(aminoester) dendrimer for safe and effective siRNA delivery

Small interfering RNA (siRNA)-based therapeutics represent a novel and compelling drug modality, provided that safe and competent vectors are available for their delivery. Here, we report a biodegradable amphiphilic poly(aminoester) dendrimer for effective siRNA delivery. This dendrimer is readily b...

Description
Summary:Small interfering RNA (siRNA)-based therapeutics represent a novel and compelling drug modality, provided that safe and competent vectors are available for their delivery. Here, we report a biodegradable amphiphilic poly(aminoester) dendrimer for effective siRNA delivery. This dendrimer is readily biodegradable upon enzyme action, and harnesses the delivery features of both lipid and polymer vectors thanks to its lipid/dendrimer hybrid structure. This study opens new perspectives for developing biodegradable and biocompatible vectors for siRNA therapeutics. An amphiphilic poly(aminoester) dendrimer demonstrating excellent siRNA delivery performance with advantageous biodegradability and the integrated delivery features of both lipid and polymer vectors.
