PHGDH ^[1]
(Cell-free)

2.5 μM

In vitro

NCT-503 has reasonable aqueous solubility, and exhibits favorable absorption, distribution, metabolism and excretion (ADME) properties^[1].

NCT-503 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
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 NCT-503 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].
Animal Research	Animal Models	NOD.SCID mice bearing MDA-MB-231 and MDA-MB-468 orthotropic xenografts
	Dosages	40 mg/kg

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

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.
