DC57002	LIPID C24	C24 is a novel multiprotic ionizable lipid. C24 lipid nanoparticle (LNP) has a multistage protonation behavior resulting in greater endosomal protonation and greater translation compared to the standard reference MC3 LNP. C24 LNP also lower injection site inflammation and higher stability compared to MC3 LNP.
DC67480	Sanofi Lipid VII	Lipid VII is a novel ionizable cationic lipid developed by Sanofi.Lipid VII demonstrates exceptional performance as a lipid nanoparticle delivery system, combining high efficiency with outstanding safety. Cellular assays reveal VII achieves 180,000 RLU transfection efficiency under serum conditions, surpassing traditional SS-OP systems by 2.25-fold while maintaining perfect 100% cellular viability and eliminating cytotoxicity risks that plague alternatives. In vivo systemic delivery shows rapid whole-body biodistribution, reaching photon emission levels exceeding 1.00E+10 photons/sec within 48 hours. VII exhibits superior organ targeting with a liver-specific accumulation ratio of 9.0, outperforming SS-OP systems by 50%, while reducing off-target spleen accumulation by 20%. Its versatility is further validated in therapeutic protein expression, where structural analogs achieve erythropoietin concentrations of 14 ng/mL, exceeding industry standards by 180%. For vaccine applications, VII generates a median HAI titer of 7,611 against H1N1 influenza—540 times higher than baseline buffers and more than double the next-best formulation. This evidence establishes VII as a breakthrough technology, offering unmatched efficiency, precision targeting, and clinical-grade safety across diverse applications.
DC65412	Acuitas Lipid III-2	Acuitas Lipid III-2 is an ionizable amine lipid with two identical ester tails adjacent to C6 position relative to amine from patent:WO2017075531A1 with the similar activity as ALC-0315. The head of lipid is propanolamine which can effectively encapsulate mRNA used in gene therapies which depends on the availability of a safe and efficient delivery vehicle.
DC60789	SM-86 Analog-1	SM-86 Analog-1 is a novel ionizable lipid designed to improve the delivery of RNA via lipid nanoparticles (LNPs) It is derived from SM-86,with 8 carbon within its hydrophobic tail.
DC153158	ND-O1 (SM-86 Analog-2)	ND-O1 (SM-86 Analog-2) is a novel ionizable lipid designed to improve the delivery of siRNA via lipid nanoparticles (LNPs) for treating liver fibrosis. It is derived from SM-86 (structurally similar to SM-102, used in COVID-19 mRNA vaccines) but incorporates an ether bond within its hydrophobic tail, a first-of-its-kind modification aimed at enhancing delivery efficiency. In Vitro Efficiency: ND-O1 LNPs (LNP-O1) showed significantly higher siRNA transfection efficiency in activated fibroblasts compared to Lipid 5 LNPs (LNP-M). In Vivo Efficacy: In a CCl4-induced liver fibrosis mouse model, LNP-O1/siHSP47 (loaded with HSP47-targeting siRNA) reduced HSP47 expression by ~84%, threefold more effective than LNP-M. This led to a dramatic reduction in collagen deposition and marked improvement in liver fibrosis. Safety: The ether bond modification did not introduce additional toxicity, maintaining biocompatibility. ND-O1 represents a breakthrough in ionizable lipid design, demonstrating that strategic placement of ether bonds in hydrophobic tails can enhance LNP performance without compromising safety. Its success highlights its potential for clinical translation in RNA-based therapies for liver fibrosis and other hepatic diseases.
DC67219	Lipid 29 analogue-3	Lipid 29 analogue-3 is an ionizable lipid designed for the delivery of RNA-based therapeutics, such as mRNA or siRNA.
DC67217	Moderna Lipid 48	Moderna Lipid 48 is an novel ionizable amine lipid used for mRNA delivery from Moderna patent WO2017049245A2
DC67216	Moderna Lipid 26（Lipid M）	Moderna Lipid 26（Lipid M） is an ionizable cationic lipid (pKa = 6.75) that has been used in the generation of lipid nanoparticles (LNPs) for mRNA delivery in vivo. LNPs containing lipid M and encapsulating mRNA encoding influenza virus genes increase anti-influenza virus IgG titers in cynomolgus monkeys without inducing local edema, erythema, or systemic levels of IL-6.
