The Headgroup Evolution of Cationic Lipids for Gene Delivery

Zhi, Defu, Zhang, Shubiao, Cui, Shaohui, Zhao, Yinan, Wang, Yinhuan, Zhao, Defeng·2013·Bioconjugate Chemistry

Abstract

Cationic lipids are one of the most widely used nonviral vectors for gene delivery and are especially attractive because they can be easily synthesized and extensively characterized. Additionally, they can best facilitate the elucidation of structure-activity relationships by modifying each of their constituent domains. The polar hydrophilic headgroups enable the condensation of nucleic acids by electrostatic interactions with the negatively charged phosphate groups of the genes, and further govern transfection efficiency. The headgroups of cationic lipids play a crucial role for gene delivery; they can be quaternary ammoniums, amines, aminoacids or peptides, guanidiniums, heterocyclic headgroups, and some unusual headgroups. This review summarizes recent research results concerning the nature (such as the structure and shape of cationic headgroup) and density (such as the number and the spacing of cationic headgroup) of head functional groups for improving the design of efficient cationic lipids to overcome the critical barriers of in vitro and in vivo transfection.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
