USP1-IN-9 (Compound 1m) is a reversible and noncompetitive inhibitor of the ubiquitin-specific enzyme (USP1) with an IC50 value of 8.8 nM. It is designed and synthesized as a pyridine [2,3-d] pyrimidine-7(8H)-1 derivative based on the structures of ML323 and KSQ-4279. USP1-IN-9 has a good inhibitory effect on USP1/UAF and has a strong anti-proliferative effect on breast cancer cells. USP1-IN-9 combined with the PARP inhibitor olaparib can enhance the killing effect on MDA-MB-436/OP cells. USP1-IN-9 is expected to be used in cancer research.

Biological Activity


Targets USP-1 8.8 nM (IC50)
ln Vitro USP1-IN-9 (20, 100, 500 nM, 24 h) increased the level of monoubiquitinated proliferating cell nuclear antigen (Ub-PCNA) in non-small cell lung cancer (NSCLC) cells in a dose-dependent manner, and USP1-IN-9 also showed an increase in Ub-PCNA at a concentration as low as 20 nM [1]. USP1-IN-9 (0.5 μM, 7 days) significantly inhibited the colony-forming ability of NSCLC cells [1]. USP1-IN-9 (1 nM, 24 h) alone caused a slight cell cycle arrest in olaparib-resistant breast cancer cells, while the combination of olaparib (HY-10162) and USP1-IN-9 caused cell cycle arrest [1]. The combination of USP1-IN-9 (100 nM, 7 days) and olaparib can enhance the killing effect of olaparib on breast cancer cells[1].
ln Vivo USP1-IN-9 (10 mg/kg, ig) was rapidly absorbed and showed good metabolic stability in male ICR mice[1].
Cell Assay Western Blot Analysis[1]
Cell Types: NSCLC
Tested Concentrations: 20, 100, 500 nM
Incubation Duration: 24 h
Experimental Results: Elevated the monoubiquitinated PCNA (Ub-PCNA) levels in a dose-dependent manner in NSCLC cells.

Cell Viability Assay[1]
Cell Types: NSCLC
Tested Concentrations: 0.5 nM
Incubation Duration: 7 days
Experimental Results: Exhibited a substantial inhibition of the colony forming capacity of breast cancer cells compared to the untreated control. Cell Cycle Analysis[1]
Cell Types: Breast cancer cells and olaparib-resistant breast cancer
Tested Concentrations: 1 nM
Incubation Duration: 24 h
Experimental Results: Resulted in a minor increase in cells within the S phase, whereas the combination of olaparib and USP1-IN-9 led to an accumulation of cells within the S phase and G2/M phase.

Cell Viability Assay[1]
Cell Types: Olaparib-resistant breast cancer
Tested Concentrations: 100 nM
Incubation Duration: 7 days
Experimental Results: Alone exhibited a reduction of 30% and did not demonstrate significant cell killing. The inhibition rate of colony formation was further elevated to 50 % combined with USP1-IN-9 and olaparib(100 nM).

Solubility Data


Solubility (In Vitro) May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples
Solubility (In Vivo) Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.

Injection Formulations
(e.g. IP/IV/IM/SC)

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.
