QC6352 is an orally active KDM4 inhibitor with anti-tumor and anti-proliferative activity. QC6352 has in vivo inhibitory effects on PDX models of breast and colon cancer and reduces the number of chemoresistant cell populations. QC6352 inhibits KDM4 different isoforms with IC₅₀s of 104 nM (KDM4A), 56 nM (KDM4B), 35 nM (KDM4C), and 104 nM (KDM4D), respectively. QC6352 has moderate inhibitory activity against KDM5 with an IC₅₀ of 750 nM (KDM5B).

KDM5-C70 is an ethyl ester derivative of KDM5-C49 and a potent, cell-permeable and pan-KDM5 histone demethylase inhibitor. KDM5-C70 has an antiproliferative effect in myeloma cells, leading to genome-wide elevation of H3K4me3 levels.

KDOAM-25 citrate is a potent and highly selective histone lysine demethylases 5 (KDM5) inhibitor with IC₅₀s of 71 nM, 19 nM, 69 nM, 69 nM for KDM5A, KDM5B, KDM5C, KDM5D, respectively. KDOAM-25 citrate increases global H3K4 methylation at transcriptional start sites and impairs proliferation in multiple myeloma MM1S cells.

AS8351 (NSC51355) is a KDM5B inhibitor, which can induce and sustain active chromatin marks to facilitate the induction of cardiomyocyte-like cells.

GSK467 is a cell penetrant and selective KDM5B (JARID1B or PLU1) inhibitor with a K_i of 10 nM and an IC₅₀ of 26 nM. GSK467 shows 180-fold selectivity for KDM4C and no measurable inhibitory effects toward KDM6 or other Jumonji family members.

TK-129 is an orally active, low-toxicity, potent KDM5B inhibitor (with high affinity; IC₅₀=44 nM). TK-129 exerts cardioprotective effects by inhibiting KDM5B and blocking the KDM5B-associated Wnt pathway. TK-129 reduces ang II-induced activation of cardiac fibroblasts in vitro and reduces isoprenaline-induced myocardial remodelling and fibrosis in vivo. TK-129 can be used in studies of cardiovascular disease.

KDM5A-IN-1 is a potent, orally bioavailable pan-histone lysine demethylases 5 (KDM5) inhibitor with IC₅₀s of 45 nM, 56 nM and 55 nM for KDM5A, KDM5B and KDM5C, respectively, and with an EC₅₀ value of 960 nM for PC9 H3K4Me3. KDM5A-IN-1 is significantly less potent against other KDM5B enzymes (1A, 2B, 3B, 4C, 6A, 7B).

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.

JQKD82 (JADA82) trihydrochloride is a cell-permeable and selective KDM5 inhibitor. JQKD82 trihydrochloride increases H3K4me3 and can be used for the research of multiple myeloma.

KDM5-IN-1 is a potent, selective and orally bioavailable KDM5 inhibitor with an IC₅₀ of 15.1 nM.

PBIT is a specific inhibitor of the Jumonji AT-rich Interactive Domain 1 (JARID1) enzymes. PBIT inhibits JARID1B (KDM5B or PLU1) histone demethylase with an IC₅₀ of about 3 μM . PBIT also inhibits JARID1A and JARID1C with IC₅₀s of 6 μM and 4.9 μM, respectively.

KDM5-C49 (KDOAM-20) is a potent and selective inhibitor of KDM5 demethylases, with IC₅₀s of 40 nM, 160 nM, and 100 nM for KDM5A, KDM5B, and KDM5C enzymes, respectively. KDM5-C49 can be used for the research of cancer.

N19-0881 (Compound 33) is an orally active, potent and selective KDM5A/5B histone lysine demethylase inhibitor (IC₅₀= 0.013 μM and 0.002 μM, respectively). N19-0881 is promising for research of epigenetically dysregulated tumors (e.g., breast cancer).

JQKD82 (JADA82) is a cell-permeable and selective KDM5 inhibitor. JQKD82 increases H3K4me3 and can be used for the research of multiple myeloma.
