DC33635	DODAP	DODAP, also known as 1,2-Dioleoyl-3-dimethylammonium-propane, is a cationic lipid. It has been used as a component in liposomes that can be used to encapsulate siRNA, immunostimulatory oligodeoxynucleotides, antisense oligonucleotides, or chemotherapeutic agents for in vitro and in vivo delivery.
DC33636	DOTAP	DOTAP, also known as 1,2-Dioleoyl-3-trimethylammoniumpropane, is a cationic liposome-forming compound used for transfection of DNA, RNA, and other negatively charged molecules into eukaryotic cells. It has been used in gene delivery vectors for gene ther
DC60848	Lipid 854	Lipid 854 is an ionizable cationic lipid that has been used in the generation of lipid nanoparticles (LNPs) for the delivery of mRNA in vivo. Lipid 854 has been optimized based on Lipid 88.
DC60842	Lipid H7T4-4	H7T4-4 is an ionizable lipid designed for mRNA delivery via lipid nanoparticles (LNPs). It features a cyclic amine headgroup (derived from cyclen tetrahydrochloride) and four C14 hydrophobic alkyl tails, synthesized through a Michael addition reaction between cyclen and 1,2-epoxytetradecane. With a high transition temperature (Tm = 58.6°C) due to strong intermolecular interactions from its cyclic headgroup and multi-tail structure, H7T4-4 alone forms rigid aggregates incompatible with mRNA encapsulation. However, when blended with low-Tm helper lipids (e.g., DOPE, Tm = -16°C), the system’s overall Tm decreases, enabling stable LNP formation. Optimized formulations (20% H7T4-4, 41% DOPE, 38% cholesterol, 1% DMG-PEG) exhibit efficient mRNA encapsulation (>90%) and transfection. Structural analyses (SAXS, cryo-TEM) confirm monodisperse LNPs with lamellar/hexagonal phases. In vivo, H7T4-4 LNPs show tumor-targeted and intranasal mRNA delivery with reduced off-target accumulation compared to SM-102-based LNPs. This rational design highlights Tm-guided helper lipid selection to overcome rigidity challenges in ionizable lipids.
DC60800	18-2-9b2	18-2-9b2 is a dendron-like degradable ionizable lipid which facilitates mRNA delivery to splenic macrophages. 18-2-9b2 LNP encapsulating therapeutic BTB domain and CNC homologue 1 (BACH1) mRNA exhibited proficient BACH1 expression and subsequent Spic downregulation in splenic red pulp macrophages (RPM) in a Spic-GFP transgene model.
DC65362	BP Lipid 114	BP Lipid 114 is a well-designed ionizable lipid optimized for mRNA encapsulation and delivery. Its ethanolamine headgroup, ester bonds at the C6 and C8 positions, and 9-carbon tail contribute to efficient mRNA complexation, stability during delivery, and improved biodegradability. These properties make it a valuable component in LNPs for gene therapy and other mRNA-based therapeutic applications.
DC65390	BP Lipid 135	BP Lipid 135 is a well-designed ionizable lipid optimized for mRNA encapsulation and delivery. Its propanolamine headgroup, ester bonds at the C8 position, and 9-carbon tail contribute to efficient mRNA complexation, stability during delivery, and improved biodegradability. These properties make it a valuable component in LNPs for gene therapy and other mRNA-based therapeutic applications.
DC60579	Lipid B3	Lipid B3 is a biodegradable ionizable lipid for liver targeted delivery. Lipid B3-LNP shows high delivery efficacy and low toxicity in delivering RNA to liver cells.
DC85555	2-Octyldecyl 6-[[4-(decyloxy)-4-oxobutyl](2- hydroxyethyl)amino]hexanoate	YK-009 is a novel ionizable lipid for mRNA delivery. Comparisons of YK009-LNP-mRNA and commercial MC3-LNP-mRNA showed that YK009-LNP-mRNA vaccines had good biodistribution patterns, favorable tissue clearance, and high delivery efficiency. Furthermore, our study proved that YK009-LNP-Omicron mRNA could trigger a robust immune response and immune protection against the SARS-CoV-2 Omicron variant.
DC82301	IC-8(lipid MIC5)	IC8 is an ionizable cationic lipid. It has been used in combination with other lipids for the formation of lipid nanoparticles (LNPs). Immunization with severe acute respiratory coronavirus 2 (SARS-CoV-2) spike glycoprotein mRNA in IC8- and manganese-containing LNPs induces IgG responses to SARS-CoV-2 Delta and Omicron variants in mice.1 Administration of mRNA encoding B7-H3 X CD3 bispecific T cell engaging (BiTE) antibodies in IC8-containing LNPs reduces tumor growth in MV4-11 and A375 mouse xenograft models.
