Field of application
NT1-O12B, an endogenous chemical and a neurotransmitter-derived lipidoid (NT-lipidoid), is an effective carrier for enhanced brain delivery of several blood-brain barrier (BBB)-impermeable cargos. Doping NT1-O12B into BBB-impermeable lipid nanoparticles (LNPs) gives the LNPs the ability to cross the BBB. NT-lipidoids formulation not only facilitate cargo crossing of the BBB, but also delivery of the cargo into neuronal cells for functional gene silencing or gene recombination.

Cat. No. Product name Field of application
DC67521 Lipid TD5 TD5 is a brain-targeting lipid nanoparticle (BLNP) engineered for efficient mRNA delivery to the central nervous system (CNS) via intrathecal injection. It incorporates a tryptamine-derived ionizable lipid headgroup, myristic acid hydrocarbon tails, and a biodegradable carbonate ester linker, enabling pH-dependent mRNA encapsulation (81.7% efficiency) and brain cell-specific targeting. With a hydrodynamic diameter of 107.5 nm, near-neutral pKa (7.30), and mild positive charge, TD 5 demonstrates superior CNS tropism through serotonin receptor (5-HT1A)-mediated endocytosis. In vitro, TD-5 achieved 80.8% GFP expression in SH-SY5Y neuronal cells, outperforming MC3 LNPs by 50-fold. Following intrathecal administration in mice, TD-5 mediated GFP expression in 29.6% of neurons and 38.1% of astrocytes brain-wide, with 10-fold higher CNS specificity than peripheral organs. Genome editing studies showed TD5-delivered Cas9/sgRNA induced tdTomato activation in ≈30% of neurons and 40% of astrocytes across key brain regions. Safety profiling revealed minimal systemic immune responses (lower IL-6, IL-12p40 vs MC3 LNPs), normal hepatic/renal biomarkers, and no histopathological toxicity. The optimized structure balances myristic chain hydrophobicity for membrane interaction, ionizable amines for mRNA complexation, and tryptamine-mediated targeting for enhanced CNS uptake, establishing TD5 as a promising platform for CNS gene therapies.
DC82025 306-O12B-3 306-O12B-3 is an ionizable lipidoid with cationic properties, commonly used in lipid nanoparticle (LNP) formulations for antisense oligonucleotide (ASO) delivery. When administered intravenously in mice, LNPs incorporating 306-O12B-3 exhibit liver-specific accumulation. Studies show that ASO-loaded LNPs containing 306-O12B-3 effectively silence hepatic PCSK9 expression by targeting the proprotein convertase subtilisin/kexin type 9 gene. Additionally, when combined with the cationic lipidoid NT1-O14B (Item No. 37095), these LNPs can deliver tau-targeting ASOs to the brain, reducing tau protein levels in mice.
DC60212 NT1-O14B NT1-O14B is a tryptamine-containing cationic lipidoid.1 It has been used in combination with other lipids in the formation of lipid nanoparticles (LNPs). Intravenous administration of LNPs containing NT1-O14B and encapsulating antisense nucleotides against tau decreases tau brain levels in mice.
