TH588 (TH-588) is a novel and highly potent inhibitor of human 7,8-Dihydro-8-oxoguaninetriphosphatase MTH1 (NUDT1) with antitumor activity. It exhibits good metabolic stability and has an IC50 of 5 nM for inhibiting MTH1. Cancers have abnormal redox regulation, which leads to the production of reactive oxygen species, which harms both free dNTPs and DNA. To stop damaged bases from being incorporated during DNA replication, the MTH1 protein sanitizes oxidized dNTP pools. The MTH1 protein in cells is powerfully and specifically engaged and inhibited by TH588, a first-in-class nudix hydrolase family inhibitor. The inhibitor binds to MTH1's active site, as shown by protein co-crystal structures.

| ln Vitro |
TH588 selectively kill U2OS and other cancer cell lines with less toxic to several primary or immortalized cells. Additionally, TH588 causes DNA damage, which results in DNA repair and an ATM-p53-mediated death response in U2OS cells. [1]
|
| ln Vivo |
TH588 (30 mg/kg s.c.) inhibits MTH1 to slow the growth of tumors in mice with xenografts of the breast tumor MCF7 or the colorectal tumor SW480. TH588 (30 mg/kg s.c.) also slows the growth of tumors in mice bearing xenografts from patients with BRAFV600E mutations. [1]

| Animal Protocol |
SCID mice bearing SW480 xenografts or MCF-7 xenografts; NOD-SCID IL2Rγnull (NOG) mice bearing patient with BRAFV600E mutated xenografts
30 mg/kg, once daily s.c. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.47 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (8.47 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (8.47 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
