In vivo NMS-P118 is proved to be metabolically stable, it modestly inhibits two cytochrome P450 family members (CYP-2B6 IC50, 8.15 μM; CYP-2D6 IC50, 9.51 μM) out of eight isoforms tested. NMS-P118 has low in vivo clearance, and complete oral bioavailability. The pharmacokinetic profile of NMS-P118 in rat dosed iv at 10 mg/kg and orally at 10 and 100 mg/kg, mirrors that observed in the mouse, with oral bioavailability >65%, and linearity of exposure with dose. Its treatment dramatically decreases intratumoral PAR levels at 1, 2, and 6 h after administration and partial recovery of PAR levels is observed at 24 h. NMS-P118 shows excellent ADME and pharmacokinetic profiles, high oral availability in the mouse and rat, and high efficacy both as a single agent and in combination with Temozolomide in BRCA1-mutated MDA-MB-436 and BRCA2 deficient Capan-1 human tumor xenograft models, respectively[1].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: HeLa cells
  • Concentrations: --
  • Incubation Time: 30 mins
  • Method: 6000 cells/well are seeded in 96-well plates in MEM/10% FCS and incubated for 24 h at 37℃, 5% carbon dioxide. Test compounds are then added at the required concentration for 30 min. DNA damage is then induced by adding hydrogen peroxide at the concentration of 0.1 mM for 15 min. Concentration curves are prepared in MEM/10% FCS from compound stocks in DMSO, and final DMSO concentration is 0.002% (v/v). Duplicate wells for each concentration point are prepared with a typical highest compound concentration of 20 μM and serial dilution 1:3. Plates are dried and fixed by adding cold methanol−acetone (70:30) solution for 15 min at room temperature, fixing solution is aspired, and wells are air-dried for 5 min and then dehydrated in PBS. Nonspecific binding sites are blocked by incubating wells for 30 min in PBS containing 5% (w/v) FBS 0.05% Tween 20. Wells are then incubated for 1 h at room temperature in PBS containing anti-PAR mouse monoclonal antibody diluted 1:200 in blocking solution. After three washes in PBS, wells incubate in PBS (w/v) 5% FBS 0.05% Tween 20 containing 2 μg/mL Cy2-conjugated Goat anti-mouse secondary antibody and 1 μg/mL DAPI. After washing further three times in PBS, cellular PAR immunoreactivity is assessed.
Animal Research:[1]
  • Animal Models: Balb, Nu/Nu mice
  • Dosages: 10 mg/kg
  • Administration: i.v.

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.
