In vitro assessment of the binding and functional responses of ozanimod and its plasma metabolites across human sphingosine 1-phosphate receptors.

Ozanimod is approved in multiple countries for the treatment of adults with either relapsing multiple sclerosis or moderately to severely active ulcerative colitis. Ozanimod is metabolized in humans to form seven active plasma metabolites, including two major active metabolites CC112273 and CC1084037, and an inactive metabolite. Here, the binding and activity of ozanimod and its metabolites across human sphingosine 1-phosphate receptors were determined.

Deconstructing the Pharmacological Contribution of Sphingosine-1 Phosphate Receptors to Mouse Models of Multiple Sclerosis Using the Species Selectivity of Ozanimod, a Dual Modulator of Human Sphingosine 1-Phosphate Receptor Subtypes 1 and 5.

Ozanimod, a sphingosine 1-phosphate (S1P) receptor modulator that binds with high affinity selectively to S1P receptor subtypes 1 (S1P) and 5 (S1P), is approved for the treatment of relapsing multiple sclerosis (MS) in multiple countries. Ozanimod profiling revealed a species difference in its potency for S1P in mouse, rat, and canine compared with that for human and monkey. Site-directed mutagenesis identified amino acid alanine at position 120 to be responsible for loss of activity for mouse, rat, and canine S1P, and mutation back to threonine as in human/monkey S1P restored activity.

The Relationship of UGT2B15 Pharmacogenetics and Lorazepam for Anxiety.

Anxiety affects over 260 million people worldwide. Benzodiazepines are a class of agents used in combination with other therapies for the management of anxiety. Lorazepam is a commonly prescribed benzodiazepine metabolized by uridine 5'-diphosphate-glucuronosyltransferases.
