A-METHYL-L-TRYPTOPHAN Chemical Properties,Uses,Production

Chemical Properties

White to off-white powder

Uses

α-methyl-DL-tryptophan is used as a blocker of ATBo, an amino acid transporter whose expression is upregulated in cancer. It is also a substrate or non-transported inhibitor of the amino acid transporter PAT2 (slc36a2).

Biochem/physiol Actions

α-methyl-DL-tryptophan is a blocker of ATBo, an amino acid transporter whose expression is upregulated in cancer.

in vivo

α-Methyl-DL-tryptophan (α-MT) (2 mg/mL; administered in drinking water; continuously administered; throughout the experimental period) inhibits tumor growth in BALB/c nude mice inoculated with ZR-75-1 cells^[1].
α-Methyl-DL-tryptophan (1 mg/mL; administered in drinking water; continuously administered; for 1 week) reduces body weight in wild-type mice on a high-fat diet^[2].

Animal Model:	BALB/c nude mice (female) inoculated with ZR-75-1 cells^[1]
Dosage:	2 mg/mL
Administration:	Administered in drinking water
Result:	Reduced the growth of ZR-75-1 cells. Tumor size was significantly smaller than that in the control group.

Animal Model:	Wild-type C57BL/6 male mice fed a high-fat diet^[2]
Dosage:	1 mg/mL
Administration:	Administered in drinking water, continuously for 1weeks
Result:	Led to a decrease in body weight.
