MLN3126, an antagonist of the chemokine receptor CCR9, ameliorates inflammation in a T cell mediated mouse colitis model
Int Immunopharmacol 2018 Jul;60:160-169.PMID:29730559DOI:10.1016/j.intimp.2018.04.049.
C-C chemokine receptor 9 (CCR9) is the homing receptor for C-C motif chemokine ligand 25 (CCL25), and contributes to the maintenance of mucosal immunity and pathogenesis of inflammatory bowel disease (IBD) through the recruitment of T cells into the gut mucosa. Recent reports suggest that the interaction of CCR9 and CCL25 in the large intestine correlate with disease severity of colonic IBD. MLN3126 is an orally available small molecular compound with potent and selective CCR9 antagonist activity. MLN3126 inhibited CCL25-induced calcium mobilization in human CCR9 transfected cells and CCL25-induced chemotaxis of mouse primary thymocytes in a dose-dependent manner. The potential effect of MLN3126 in an activated T cell transfer mouse colitis model was compared with that of an anti-tumor necrosis factor (TNF)-α antibody. CCL25 protein was detected in the colon of mucosal epithelial cells and CCR9+ CD4+ T cells were observed in the lamina propria of the colon of mice with colitis. Dietary administration of MLN3126 to the mice maintained sufficient concentration of the compound in the plasma and dose-dependently inhibited progression of colitis compared to the vehicle control group. Anti-TNF-α antibody, a surrogate for a standard of care for IBD treatment, was also efficacious in the colitis model. These results suggest that MLN3126 would be a promising orally available CCR9 antagonist to treat colonic IBD.
Mechanism for Covalent Binding of MLN3126, an Oral Chemokine C-C Motif Receptor 9 Antagonist, to Serum Albumins
Drug Metab Dispos 2018 Mar;46(3):204-213.PMID:29269409DOI:10.1124/dmd.117.078782.
N-{4-Chloro-2-[(1-oxidopyridin-4-yl)carbonyl]phenyl}-4-(propan-2-yloxy)benzenesulfonamide (MLN3126) is an orally available chemokine C-C motif receptor 9 selective antagonist. In nonclinical pharmacokinetic studies of MLN3126, nonextractable radioactivity was observed in plasma after oral administration of 14C-labeled MLN3126 ([14C]MLN3126) to Sprague-Dawley (SD) rats. In this study, the nonextractable radioactive component was digested with trypsin or a nonspecific protease, pronase, after chemical reduction to obtain drug-peptide adducts or drug-amino acid adducts. The chemical structure of these adducts was characterized by liquid chromatography/mass spectrometry. The results demonstrated that the major part of the nonextractable radioactivity was accounted for by covalent binding via the Schiff base formed specifically between the ε-amino group of lysine residue 199 in rat serum albumin and the carbonyl group of MLN3126. The half-life (t1/2) of the total radioactivity in plasma during and after 21 daily multiple oral administrations of [14C]MLN3126 to SD rats was approximately 5-fold shorter than the reported t1/2 of albumin in rats. The data indicated that the covalent binding was reversible under physiologic conditions. The formation of the covalent binding was also confirmed in in vitro incubations with serum albumins from rats, humans, and dogs in the same manner, indicating that there are no qualitative interspecies differences in the formation of the Schiff base.
