Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	mTDO ^[1] (in P815B cells) 2 μM
In vitro	LM10 (Ki=5.6 μM) displays an excellent selectively prolfile and does not display any inhibitory potency on IDO^[1].
In vivo	LM10 has high plasma concentration and oral bioavailability in mouse. The plasma concentration of this compound after oral administration of 160 mg/kg/day is between 20 and 40 μg/mL (87-175 μM), a concentration about 40 times above the IC50 measured in the cellular assay performed with the physiological concentration of plasma tryptophan. Systemic treatment of immunized mice with this chemical at 160 (mg/kg)/day prevents the growth of TDO-expressing P815 tumor cells. Moreover, mice treated with it do not show obvious signs of toxicity^[1]^[2].
