Emavusertib
Based on 7 publication(s) in Google Scholar
Emavusertib is an orally active inhibitor for IRAK4 (IC50=57 nM) and FLT3. Emavusertib inhibits NF-κB and MyD88 signaling pathways, reduces the generation of pro-inflammatory cytokines like IL-6 and IL-10, thereby exhibiting anti-inflammatory and anti-proliferative activities against cancer cells, leading to cell apoptosis. Emavusertib exhibits antitumor activity in mouse model

[PMID: 33335659] |
Emavusertib (CA-4948) is over 500-fold more selective for IRAK-4 compared to IRAK-1. Emavusertib reduces TNF-α, IL-1β, IL-6 and IL-8 release from TLR-Stimulated THP-1 Cells with an IC50 <250 nM. Emavusertib also has antiproliferative activity due to inhibition of receptor-type tyrosine-protein kinase FLT3[1].
Emavusertib exhibits >350-fold higher binding affinity for IRAK-4 than that observed for IRAKs 1, 2 and 3[3].
Emavusertib (10 μM, 72 h) decreases the percentage of proliferating cells and induces a moderate increase in the sub-G0 fraction in marginal zone lymphomas (MZL) cell lines[3].
Emavusertib (10 μM, 72 h) induces a significant increase in the apoptotic cell population of MZL cells, particularly when combined with Ibrutinib (HY-10997) compared to ibrutinib and emavusertib alone[3].

Emavusertib (25-150 mg/kg, Orally, once daily, for 14 consecutive days) induces tumor growth inhibition in mice[3].

Animal Model:Mice bearing OCI-LY10 tumors[3]
-
Dosage:25, 50, or 150 mg/kg (once daily), 12.5, 25, or 50 mg/kg (twice daily)
-
Administration:Orally, once daily or twice daily, for 14 consecutive days
-
Result:Induced tumor growth inhibition. Emavusertib administered as a twice-daily divided dose was equivalent to the corresponding once-daily dose with regards to antitumor activity, i.e., 12.5 mg/kg BID versus 25 mg/kg QD.
