NSC 319726 is a p53(R175) mutant activator that inhibits the growth of p53(R175) mutant cells and acts on p53(R175) mutant cells with IC50 of 8 nM, which has no inhibition on p53 wild-type cells. NSC 319726 is a potent copper ion-carrier that can be used in cuproptosis studies.

| Method | immunoprecipitation | |
| Cell Lines | R175H cells | |
| Concentrations | 1 μM | |
| Incubation Time | 24 h | |
| Results | We incubated TOV112D cells with either ZMC1 or NTA and performed immunoprecipitation (IP) experiments with the antibody PAB240, which specifically recognizes misfolded and unfolded p53. |
| Molecular Weight | 234.32 |
| Formula | C11H14N4S |
| CAS Number | 71555-25-4 |
| Solubility (25°C) | DMSO 16 mg/mL |
| Storage |
Powder -20°C 3 years ; 4°C 2 years In solvent -80°C 6 months ; -20°C 1 month |
| Species | Mouse | Rat | Rabbit | Guinea pig | Hamster | Dog |
| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
