General description

5-Methoxy-L-tryptophan is a L-tryptophan metabolite that exhibits anti-inflammatory and tumor-suppressing activities. 5-Methoxy-L-tryptophan is synthesized by tryptophan hydroxylase (TPH) and hydroxyindole O-methyltransferase (HIOMT). A recent study indicates 5-methoxytryptophan as a biomarker of the progression of chronic kidney disease (CKD). Its levels decrease during disease and treatment with 5-methoxytryptophan ameliorates kidney fibrosis in mice model of CKD. 5-Methoxytryptophan appears to inhibit IκB/NFκB signaling and enhances Keap1/Nrf2 signaling in mice models of unilateral ureteral obstruction.

Application

5-Methoxy-L-tryptophan finds application in cell biology, biochemical and metabolomics research.

5-Methoxytryptophan (5-MTP) is a tryptophan metabolite with recently discovered anti-inflammatory and tumor-suppressing activities. Its synthesis is catalyzed by a hydroxyindole O-methyltransferase (HIOMT)-like enzyme. However, the exact identity of this HIOMT in human cells remains unclear. Human HIOMT exists in several
