CPI-455 hydrochloride
Based on 17 publication(s) in Google Scholar
CPI-455 hydrochloride is a specific, pan-KDM5 inhibitor with an IC50 of 10 nM for KDM5A. CPI-455 hydrochloride mediates KDM5 inhibition, elevates global levels of H3K4me3, and decreases the number of drug-tolerant persister cancer cells in multiple cancer cell line models treated with standard chemotherapy or targeted agents.

KDM5 |
In Vitro
CPI-455 hydrochloride 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].
CPI-455 hydrochloride, with high measured affinity for the target KDM5 proteins. Within 24 hours, increases in H3K4me3, are observed after exposure to either of the two active compounds, CPI-455 and CPI-766, in a dosedependent manner. IC50 calculation for KDM5 Inhibitor CPI0455 in 3 luminal breast cancer cell lines MCF-7, T-47 and EFM-19 are 35.4, 26.19 and 16.13 μM, respectively[2].
