USP1-IN-9

😃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 mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
All types of co-solvents required for the protocol, such asDMSO, PEG300/ PEG400, Tween 80, SBE-β-CD, corn oil are available for purchase on the TargetMol website with a simple click.
