S-Ac7-DOg
S-Ac7-DOG is a cationic lipid with biodegradability, low immunogenicity and high nucleic acid transfection capacity, which is commonly used to construct lipid nanoparticles for nucleic acid molecule delivery. S-Ac7-DOG can bind to mRNA, microRNA and self-amplifying RNA through electrostatic interaction. Lipid nanoparticles formed by S-Ac7-DOG enter cells via an energy-dependent endocytic pathway, release nucleic acid cargos, induce antigen-specific CD8+ T cell responses, promote the generation of precursor memory T cells, and regulate neuroinflammatory pathways. S-Ac7-DOG can be used in the research of retinal diseases, neuroinflammation and cancer.

S-Ac7-DOg (5 h; stored at 4 °C)-loaded mRNA and saRNA LNPs exhibit consistent physicochemical properties (size, PDI, zeta potential, encapsulation efficiency) suitable for in vitro retinal delivery[1].
S-Ac7-DOg LNPs (0.5 μg; 24 h) mediate efficient cellular uptake and high transfection efficiency in ARPE-19 and MIO-M1 cells for mRNA delivery, with mRNA cargo inducing more eGFP-positive cells than saRNA cargo[1].
S-Ac7-DOg-based LNP (5-80 nM siRNA; 24 h) efficiently silences luciferase activity in Luc-BV2 mouse microglial cells, with comparable performance to other leading formulations at a 40 nM siRNA dose[2].
S-Ac7-DOg-based LNP (5-80 nM siRNA; 24 h) exhibits no cytotoxicity in BV2 mouse microglial cells at siRNA concentrations ranging from 5 to 80 nM after 24 h incubation[2].
S-Ac7-DOg-based LNP (40 nM miR-124; 24 h) achieves the highest miR-124 transfection efficiency in BV2 mouse microglial cells after 24 h incubation at a 40 nM miRNA dose[2].
S-Ac7-DOg-based LNP (40 nM Cy5-miR-124; 1-6 h) are internalized by BV2 mouse microglial cells via an energy-dependent, cholesterol-requiring endocytic pathway, and successfully escape from endosomes over time[2].
S-Ac7-DOG LNPs (50-200 ng mRNA; 24 h) mediate 10- to 100-fold higher eGFP expression than MC3 LNPs in HEK293T, MC38, and CT26 cells, while maintaining low cytotoxicity[3].
S-Ac7-DOG LNPs (50-200 ng mRNA; 24 h) exhibit significantly higher transfection efficiency than MC3 LNPs in CT26 cells, with no difference in cellular LNP association[3].
S-Ac7-DOG LNPs induce earlier onset of human RBC lysis at acidic pH values relative to MC3 LNPs, indicating enhanced membrane rupture activity at higher endosomal pH[3].
S-Ac7-DOG LNPs undergo more robust disassembly in the presence of anionic DOPS:DOPC liposomes at acidic pH values relative to MC3 LNPs, indicating enhanced membrane interaction capacity[3].
S-Ac7-DOG modified eLNPs can effectively bind mRNA and maintain colloidal stability and mRNA binding ability after storage.[4].
S-Ac7-DOG eLNP+ mRNA showed no detectable cytotoxicity and completely protected the mRNA from RNase degradation; cellular uptake was also higher[4].

S-Ac7-DOg (5 μg; intramuscular injection; single administration) achieves higher local miR-124 levels in the muscles of healthy mice than MC3-LNP, and induces lower expression levels of proinflammatory cytokines[2].
S-Ac7-DOG LNPs (5 μg mRNA; intramuscular injection; single administration) mediate sustained, local mRNA expression at the injection site, while reducing off-target liver distribution, resulting in higher muscle-to-systemic bioluminescence ratios and higher spleen-to-liver bioluminescence ratios[3].
S-Ac7-DOG LNPs (5 μg mRNA; intramuscular injection; single administration) exhibit low reactogenicity and unique cell tropism compared with MC3 LNPs[3].
