lipid 5

Lipid 5, an amino lipid compound, demonstrates proficient mRNA delivery in rodent and primate models, with favorable pharmacokinetics and minimal toxicity.

LNP Lipid-5 is an ionizable lipid (amino lipid) used in the formulation of lipid nanoparticles (LNP).

3D-Monophosphoryl Lipid A-5 (3D-MPLA-5) is a TLR agonist that can serve as an adjuvant in vaccines to enhance their immunogenicity.

Methyl alpha-eleostearate (α-ESA) is a conjugated polyunsaturated fatty acid commonly found in plant seed oil. This fatty acid accounts for about 60% of the total fatty acid composition of bitter gourd seed oil and about 70% in tung oil. α-ESA is metabolized and converted to conjugated linoleic acid (9Z,11E-CLA) in rats. It has shown potential as a tumor growth suppressor. In colon cancer Caco-2 cells, α-ESA induced apoptosis through up-regulation of GADD45, p53, and PPARγ. In DLD-1 cells supplemented with α-ESA, apoptosis was induced via lipid peroxidation with an EC50 of 20 μM. It also inhibits DNA polymerases and topoisomerases with IC50s ranging from ~5-20 μM for different isoforms of the enzymes. α-ESA methyl ester is a neutral, more lipid soluble form of the free acid.

Sphingosine-1-phosphate (S1P) is a bioactive lipid that exhibits a broad spectrum of biological activities including cell proliferation, survival, migration, cytoskeletal organization, and morphogenesis. It exerts its activity by binding to five distinct G protein-coupled receptors, S1P1 EDG-1, S1P2 EDG-5, S1P3 EDG-3, S1P4 EDG-6, and S1P5 EDG-8. W140 is an inactive enantiomer of W146, a selective S1P1 antagonist (Ki = 77 nM), that binds to the S1P1 receptor with a Ki of 4.6 μM (2a = W146; 2b = W140 in supplemental material). It exhibits no biological activity in vivo and can therefore serve as an effective control compound for experiments involving W146.

98N12-5, a novel multi-tail ionizable lipid, demonstrates efficient in vivo siRNA delivery to the liver.

cis-13,16,19-Docosatrienoic acid methyl ester is an ester form of docosatrienoic acid, a rare ω-3 fatty acid. This compound is not easily detectable in the normal phospholipid polyunsaturated fatty acid pool and at a concentration of 5 μM, it inhibits the binding of [3H]-LTB4 to porcine neutrophils. The methyl ester form exhibits greater lipid solubility than the free acid, potentially making it more suitable for certain formulations.

LNP Lipid-6 is an ionizable lipid (amino lipid) that is utilized in the preparation of lipid nanoparticles (LNP).

2′-Hydroxy-5′-nitrohexadecanamide is an inhibitor of lysosomal hydrolase and a lipid containing pentadecanoic acid and a terminal nitrophenol group. It induces intracellular lipid accumulation by inhibiting the activity of lysosomal hydrolases. Additionally, 2′-Hydroxy-5′-nitrohexadecanamide can be used for synthesizing chromogenic substrates to assay sphingomyelinase activity.
