Product overview

Description & Application

C14-306 is a rationally designed ionizable lipid for brain targeting delivery, characterized by a linear 3,3'-diamino-N-methyldipropylamine (306) core conjugated with tetradecyl (C14) tails. This specific architectural configuration, synthesized via epoxide ring-opening amination, yields a molecular structure that optimally balances hydrophobic character and protonation capacity. The C14 alkyl chains enhance membrane integration and LNP stability, while the multiamine core facilitates efficient mRNA complexation and pH-dependent endosomal disruption. When formulated into LNPs with standard helper lipids (DOPE, cholesterol, DMG-PEG2000), C14-306-based nanoparticles exhibit favorable physicochemical properties, including a monodisperse size distribution near 110 nm and high mRNA encapsulation efficiency (>84%). High-throughput in vivo barcoding screening identified C14-306 LNPs as lead candidates for brain delivery, demonstrating a significant tropism for neuronal cells over liver tissue. In validation studies, LNPs incorporating C14-306 achieved a 6.9-fold increase in luciferase mRNA transfection in the mouse brain compared to the SM-102 benchmark, coupled with a substantial reduction in hepatic off-target expression. Flow cytometry confirmed preferential transfection of NeuN+ neurons, and safety assessments indicated no significant blood-brain barrier compromise or induction of systemic inflammation. The efficacy of C14-306 is attributed to its tailored pKa, promoting extended circulation and enhanced endosomal escape within brain cells. C14-306 represents a promising platform for systemic mRNA therapeutics targeting neurological disorders.

Handling guidance

Shipping, storage and sampling

How is the lipid shipped, and how should I store it?
We generally ship the neat (undissolved) lipid compound rather than an ethanol solution. The neat lipid is stable during transport with ice packs, and shipments originate from Shanghai. Pure form: store at −20 °C for up to 1 year. In solvent: store at −80 °C for up to 6 months or at −20 °C for up to 1 month. Keep sealed and protected from light. Avoid repeated thaw cycles for best results.
Pure lipid or solution — which should I choose?
Pure lipid is generally more stable during shipping and storage, so we usually recommend the pure form. A solution in ethanol or chloroform can be supplied when required by your workflow. Tell us the intended application, solvent and target concentration so the most suitable format can be confirmed.
How should I measure a small amount of oily or viscous lipid?
Ionizable lipids are often oily liquids or viscous semisolids, so material can be lost during repeated weighing or transfer. For a small pack, dissolve the entire quantity and aliquot it volumetrically. For example, add 1 mL ethanol to 25 mg lipid to prepare a 25 mg/mL stock, then use a pipette to withdraw the required amount. For quantities above 100 mg, direct weighing with an analytical balance may be more practical. Always confirm solvent compatibility and solubility first.
Can you support formulation optimization and scale-up?
Yes. Share the RNA cargo, target tissue, administration route, formulation method and assay plan. Our team can discuss starting molar ratios, N/P ratio and scale-up requirements for research workflows.
