autotaxin in 1

Autotaxin-IN-1 is a potent autotaxin inhibitor used in the treatment of osteoarthritis pain. It exhibits favorable potency (IC50=2.2 nM), pharmacokinetic (PK) properties, and a robust PK pharmacodynamic (PD) relationship[1].

Lysophosphatidylcholine 18:2 is a mouse metabolite functionally related to linoleic acid.18:2 LysoPC is a major component of oxidized low-density lipoproteins (LDLs), and low plasma levels of LPC 18:2 have been associated with metabolic disorders such as impaired glucose tolerance, insulin resistance, type 2 diabetes, and coronary artery disease.1-Linoleoyl 1-Linoleoyl-2-Hydroxy-sn-glycero-3-PC is also a substrate for the generation of lysophosphatidic acid (LPA) from Autotaxin (LysoPLD), which plays an important role in cell motility.

Sphingomyelins are complex membrane lipids composed of phosphorylcholine, sphingosine, and an acylated group, such as a fatty acid. Lysosphingomyelin is a naturally-occurring lipid which is produced by the removal of the acylated group of sphingomyelin by a deacylase. Lysosphingomyelin may, in turn, serve as a substrate for autotaxin, which removes choline to produce sphingosine-1-phosphate. The receptors and signaling pathways that are activated by lyso-sphingosine are diverse and vary between cell types. Lysosphingomyelin occurs naturally in plasma, is a constituent of lipoproteins, and is increased in some diseases, including dermatitis and Niemann-Pick disease.

ATX inhibitor 15 (compound 30) is an indole-based carbamate derivative with a strong inhibitory effect on autotaxin (ATX), demonstrated by an IC50 of 2.17 nM. It effectively inhibits ATX activity in vivo, suppresses the expression of pro-fibrotic genes, and exhibits protective effects in Bleomycin-induced lung fibrosis in mice [1].

Autotaxin-IN-6 (compound 23) is a potent inhibitor of autotaxin (ATX), exhibiting an IC50 of 30 nM, and attenuates cell migration with potential applications in anticancer research [1].

Palmitoleoyl 3-carbacyclic phosphatidic acid (3ccPA 16:1) serves as a moderately effective autotaxin (ATX) inhibitor, exhibiting an IC50 value of 620 nM. This compound finds utility in melanoma research[1].

Cyclic Phosphatidic Acids (cPAs) are naturally occurring lysophosphatidic acid (LPA) analogs, characterized by a 5-membered ring formed between the sn-2 hydroxy group and the sn-3 phosphate. Carba-derivatives of cPA (ccPA) modify the sn-2 (2-ccPA) or sn-3 (3-ccPA) linkage, hindering the conversion of cPA into LPA. Oleoyl 3-Carbacyclic Phosphatidic Acid (3-ccPA 18:1) incorporates the 18:1 fatty acid oleate at the sn-1 position on the glycerol backbone, acting as a cyclic LPA analog. This compound, at a concentration of 25 μM, blocks MM1 cells' transcellular migration through mesothelial cell monolayers induced by fetal bovine serum (by 90.1%) or LPA (by 99.9%), without impeding cell proliferation. Additionally, 3-ccPA 18:1, in the 0.1-1.0 μM range, notably suppresses autotaxin, which plays a vital role in various cancer cell behaviors including survival, growth, migration, invasion, and metastasis.
