Description

CPI-455 is a specific KDM5 inhibitor with an IC50 of 10 nM for full-length KDM5A in enzymatic assays. CPI-455 shows over 200-fold selectivity for KDM5 relative to KDM2, 3, 4, 6, and 7 enzymes.

Targets

KDM5 ^[1]
(in enzymatic assays)

10 nM

In vitro
In vitro	CPI-455 mediates KDM5 inhibition, elevates global levels of H3K4 trimethylation (H3K4me3) and decreases the number of DTPs in multiple cancer cell line models treated with standard chemotherapy or targeted agents.^[1]
Cell Research	Cell lines	Melanoma (M14) cell lines, breast cancer (SKBR3) cell lines, NSCLC (PC9) cell lines
	Concentrations	6.25-25 μM
	Incubation Time	4 days, 5 days
	Method	Cells are plated in 6-well plates and treated with various concentrations of CPI-455 for up to 4 d. Cells are collected at various time points, and global levels of H3K4me3 and total H3 are determined using MSD ELISA.

In Vivo
In vivo	Dual blockade of B7-H4 and KDM5B (CPI-455, 50/70 mg/kg, ip, daily) in mice elicits protective immunity. Treatment with CPI-455 to selectively targets H3K4-specific JmjC demethylases. CPI-455 increases CXCL11, CXCL9, and CXCL10 following infection, with maximum levels observed 48 hours after infection.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
