Description: D-Lin-MC3-DMA, an ionizable cationic lipid, is a potent siRNA delivery vehicle.
In Vivo: Lipid nanoparticles (LNPs) containing distearoylphosphatidlycholine (DSPC), and ionizableamino-lipids such as dilinoleylmethyl-4-dimethylaminobutyrate (DLin-MC3-DMA) are potent siRNA delivery vehicles in vivo. LNP-siRNA systems optimize to achieve maximum gene silencing potency in hepatocytesfollowing IV administration in mice contain DLin-MC3-DMA (MC3), DSPC, cholesterol and a polyethyleneglycol (PEG)-lipid at mole ratios of 50/10/38.5/1.5. DLin-MC3-DMA exhibits an optimized pKa value that leads to dramatically enhanced potency[1].

DC59010 C14-4 (C14-494,Lipid B-4,Lipid B4) C14-4 (C14-494,Lipid B-4,Lipid B4) is a novel ionizable lipid with the highest T-cell transfection efficiency and low cytotoxicity.The C14-4 ionizable lipid has been explored for CAR-T therapy.To screen the excellent formulations for mRNA delivery, a lipid library of 24 ionizable lipids was constructed to make iLNPs, which were used to deliver luciferase mRNA into Jurkat cells.[115] The optimal iLNPs formulation was C14-4 iLNPs (C14-4 ionizable lipid, DOPE, chol, and PEG at a molar ratio of 35%, 16%, 46.5%, and 2.5%) (Figure 6c). The optimal dose of luciferase mRNA for C14-4 iLNPs was 30 ng. Compared with electroporated CAR T cells, the CAR T cells engineered via C14-4 iLNPs showed potent cancer-killing activity when they were cocultured with Nalm-6 acute lymphoblastic leukemia cells. To obtain a safer and more effective CAR mRNA delivery vehicle, the orthogonal design provided 256 potential formulations, and 16 representative iLNPs formulations were evaluated.Through evaluating the safety, delivery efficiency, and transfection efficiency of 16 iLNPs, the formulation B10 (C14-4 ionizable lipid, DOPE, chol, PEG at a molar ratio of 40%, 30%, 25%, and 2.5%) was screened out as the optimal performing formulation. The luciferase expression based on B10 formulation was increased threefold than the initial formulation. Reducing the accumulation and clearance of iLNPs in the liver can increase the expression of CAR mRNA in T cells, further improving the therapeutic effect of CAR-T. Studies have shown that cholesterol analogs can alter the mechanisms of intracellular circulation and enhance the delivery of mRNA, which may be related to the reduced recognition of iLNPs by the Niemann Pick C1 (NPC1) enzyme.The addition of a hydroxyl group to various locations in the cholesterol molecule can alter the binding kinetics between the modified cholesterol and NPC1, and reduced NPC1 recognition of cholesterol. The results showed that replacement of 25% and 50% 7 α-hydroxycholesterol for cholesterol in iLNPs improved mRNA delivery to primary human T cells in vitro by 1.8-fold and twofold, respectively.C14-4 is one of the ionizable lipids to efficiently deliver mRNA to Jurkat cells or primary human T cells. It will effectively promote the development of mRNA delivery by iLNPs for CAR-T therapy.

DC58046 C12-200 C12-200 is a cationic lipid for Lipid NanoParticles as delivery systems for enabling the therapeutic potential of siRNA, mRNA or CRISPR as they exhibit remarkable in vivo potencies at low doses.C12-200 is a common positive control ionizable lipid for exploring new ionizable lipids. C12-200 is an ionizable lipid with five tails. The tri-palmitoyl-Sglyceryl cysteine linked to the pentapeptide (Pam3)-modified C12-200 iLNPs was developed to deliver tumor antigen mRNA for enhancing the mRNA-mediated cancer immunotherapy. The results of the therapeutic evaluation showed that Pam3- modified C12-200 iLNPs could almost inhibit tumor growth in tumor-bearing mice. To improve delivery efficiency, the formulation was optimized to replace the phospholipids from DSPC to DOPE, and the result showed that optimized formulation induced EPO protein expression was seven times that of the initial formulation,[35] and the formulation has been used in the study for mRNA-mediated human α-galactosidase protein replacement therapy in mice and nonhuman primates.
