Abstract: | The autotaxin-lysophophatidic acid (ATX-LPA) signaling pathway is involved in several human diseases such as cancer, autoimmune diseases, inflammatory diseases neurodegenerative diseases and fibrotic diseases. Herein, a series of 4-phenyl-thiazole based compounds was designed and synthesized. Compounds were evaluated for their ATX inhibitory activity using FS-3 and human plasma assays. In the FS-3 assay, compounds 20 and 21 significantly inhibited the ATX at low nanomolar level (IC50 = 2.99 and 2.19 nM, respectively). Inhibitory activity of 21 was found to be slightly better than PF-8380 (IC50 = 2.80 nM), which is one of the most potent ATX inhibitors reported till date. Furthermore, 21 displayed higher potency (IC50 = 14.99 nM) than the first clinical ATX inhibitor, GLPG1690 (IC50 = 242.00 nM) in the human plasma assay. Molecular docking studies were carried out to explore the binding pattern of newly synthesized compounds within active site of ATX. Docking studies suggested the putative binding mode of the novel compounds. Good ATX inhibitory activity of 21 was attributed to the hydrogen bonding interactions with Asn230, Trp275 and active site water molecules; electrostatic interaction with catalytic zinc ion and hydrophobic interactions with amino acids of the hydrophobic pocket. |
