Rational design of cationic lipids for siRNA delivery.

    https://www.ncbi.nlm.nih.gov/pubmed/20081866
    We adopted a rational approach to design cationic lipids for use in formulations to deliver small interfering RNA (siRNA). Starting with the ionizable cationic lipid 1,2-dilinoleyloxy-3-dimethylaminopropane (DLinDMA), a key lipid component of stable nucleic acid lipid particles (SNALP) as a benchmark, we used the proposed in vivo mechanism of action of ionizable cationic lipids to guide the design of DLinDMA-based lipids …Author: Sean C Semple, Akin Akinc, Jianxin Chen, Ammen P Sandhu, Barbara L Mui, Connie K Cho, Dinah W Y Sah,...

    Nov 10, 2013 · The complexation of cationic lipids with siRNA was investigated utilizing dynamic light scattering (DLS) and a RiboGreen fluorescence-based assay that can detect free, non-encapsulated RNA. Nanoparticle formation was observed when both the lipids and siRNA were mixed together at N/P ratios above 1.0, as determined by the RiboGreen assay (data ...Author: Anthony S.

    Direct nose-to-brain (N-to-B) delivery enables the rapid transport of drugs to the brain, while minimizing systemic exposure. The objective of this work was to engineer a nanocarrier intended to enhance N-to-B delivery of RNA and to explore its potential utility for the treatment of neurological disorders. Our approach involved the formation of electrostatically driven nanocomplexes between a ...
