The data suggest that tranilast acts as a competitive inhibitor of either indoleamine 2, 3-dioxygenase (IDO), tryptophan 2,3 di-oxygenases (TDO) or both, and demonstrates a therapeutic response to manipulation of the kynurenine pathway.

Suppression and potentiation of 5‐hydroxytryptophan‐induced hypoglycaemia by α‐monofluoromethyldopa: correlation with the accumulation of 5‐hydroxytryptamine in the liver

The results further support the hypothesis that the accumulation of 5‐HT in the liver is causally related to the hypoglycaemia induced by 5‐ HTP and indicate that the LPS‐induced 5-HT accumulation in the Liver is not derived from stimulation of5‐HT synthesis.

The metabolism of L-tryptophan by liver cells prepared from fed and 48 h-starved rats was studied and tryptophan was degraded exclusively through kynurenine; there was no evidence of formation of either indol- 3-ylacetic acid or 5-hydroxyindol-3-ylACetic acid.

It is concluded that alterations in free tryptophan concentrations consequent to changes in albumin binding may be an important factor in regulating tryPTophan uptake and catabolism by the liver.

The possibility that pyruvate transport into mitochondria may be rate limiting and involved in the regulation of gluconegenesis is discussed, and alpha-cyano-4-hydroxycinnamate was shown to be accompanied by the transport of a proton (or by exchange with an OH-ion), which allowed measurements of pyruVate transport at higher temperatures to be made.
