USP1-IN-9

Copy Product Info
😃Good
Catalog No. T210294

USP1-IN-9 (Compound 1m) is a reversible and non-competitive inhibitor of ubiquitin-specific protease (USP1) with an IC50 value of 8.8 nM. It is synthesized based on the structures of ML323 and KSQ-4279 as a pyrido[2,3-d]pyrimidin-7(8H)-one derivative. USP1-IN-9 exhibits excellent inhibition of USP1/UAF and demonstrates strong antiproliferative effects on breast cancer cells. When combined with the PARP inhibitor olaparib, USP1-IN-9 enhances the cytotoxic effect on MDA-MB-436/OP cells. USP1-IN-9 holds potential for research in the field of cancer.

Targets&IC50
USP1:8.8 nM
In vitro
USP1-IN-9, at concentrations of 20, 100, and 500 nM for 24 hours, elevates the level of monoubiquitinated proliferating cell nuclear antigen (Ub-PCNA) in non-small cell lung cancer cells (NSCLC) in a dose-dependent manner, and this increase in Ub-PCNA is evident even at a low concentration of 20 nM.
In vivo
Administered at 10 mg/kg via intragastric route, USP1-IN-9 is rapidly absorbed in male ICR mice and exhibits good metabolic stability. Pharmacokinetic parameters of USP1-IN-9 in mice show a dose of 10 mg/kg orally, with a T_max of 0.25 hours, C_max of 4780 ± 2090 ng/mL, AUC_0-t of 35,800 ± 13,500 ng·h/mL, and a T_1/2 of 7.61 ± 4.67 hours.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
TargetMol | Animal experiments For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.
Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSOTargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSOTargetMol | reagent stock solution to 400 μL PEG300TargetMol | reagent and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH2OTargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
