体内（毎回新しく調製した物を用意してください）

Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%Ethanol 1 40%PEG300 2 5%Tween80 3 50%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	2.050mg/ml (5.02mM)	Taking the 1 mL working solution as an example, add 50 μL 41 mg/ml clarified Ethanol stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	NCT-503 is a phosphoglycerate dehydrogenase (PHGDH) inhibitor with the IC50 value of 2.5 μM. It is inactive against a panel of other dehydrogenases and shows minimal cross-reactivity in a panel of 168 GPCRs.
in vitro	NCT-503 has reasonable aqueous solubility, and exhibits favorable absorption, distribution, metabolism and excretion (ADME) properties^[1]. This compound selectively blocks glucose-derived serine synthesis but at the same time triggers SHMT1-dependent one-carbon unit wasting to synthesize serine from glycine. This futile cycle depletes the cell of nucleotides and leads to cell cycle arrest^[2].
in vivo	NCT-503 has good exposure (AUClast=14,700 hr*ng/mL), half-life (2.5 hr) and Cmax (~20 µM in plasma) following intraperitoneal administration with significant partitioning into the liver and brain. PHGDH inhibition by this compound selectively increases necrosis in MDA-MB-468 xenografts, but not in MDA-MB-231 xenografts. It also reduces the growth and weight of PHGDH-dependent MDA-MB-468 xenografts but does not affect the growth or weight of PHGDH-independent MDA-MB-231 xenografts^[1].
