Application

Ro 61-8048 has been used as a kynurenine 3-monooxygenase (KMO) inhibitor to study its effects on nicotinamide adenine dinucleotide (NAD+) concentration in hepatocytes of mice.

Biochem/physiol Actions

Inhibition of kynurenine 3-hydroxylase by Ro 61-8048 reduces the episodes of dystonia and dyskinesias induced by decreased levels of kynurenic acid.
Ro 61-8048 is an inhibitor of kynurenine 3-monooxygenase (KMO) that increases kynurenic acid levels and reduces extracellular glutamate in the brain.

Human African trypanosomiasis, or sleeping sickness, is caused by the protozoan parasites Trypanosoma brucei rhodesiense or Trypanosoma brucei gambiense, and is a major cause of systemic and neurological disability throughout sub-Saharan Africa. Following early-stage disease, the trypanosomes cross the blood-brain

In mammals, the majority of the essential amino acid tryptophan is degraded via the kynurenine pathway (KP). Several KP metabolites play distinct physiological roles, often linked to immune system functions, and may also be causally involved in human diseases including

Several lines of evidence support the hypothesis that abnormally elevated brain levels of kynurenic acid (KYNA), a metabolite of the kynurenine pathway (KP) of tryptophan degradation, play a pathophysiologically significant role in schizophrenia and other major neurodevelopmental disorders.

Our prior studies showed that dysfunctional plasmacytoid dendritic cells (pDCs) contribute to multiple myeloma (MM) pathogenesis. Specifically, pDC interactions with tumor and T/NK effector cells in the bone marrow (BM) milieu induce immune suppression and MM cell proliferation. Delineation of
