Edralbrutinib
Based on 1 Customer Validation
Edralbrutinib (TG-1701) is a highly selective, orally available irreversible BTK inhibitor, with an EC50 of 6.70 nM and a Kd of 3 nM against human BTK. Edralbrutinib inhibits downstream signaling of the B cell receptor, induces dephosphorylation of Ikaros Ser442/445, promotes nuclear exclusion of Ikaros, attenuates Ikaros gene signatures, and exerts anti-tumor activity. Edralbrutinib can be used in research related to B-cell non-Hodgkin lymphoma, chronic lymphocytic leukemia, mantle cell lymphoma, follicular lymphoma, and diffuse large B-cell lymphoma.

Biological Activity
Edralbrutinib (TG-1701) (1 μM) exhibits high selectivity for BTK over 440 other human kinases, with a BTK Kd of 3 nM when tested at 1 μM[1].
Edralbrutinib (TG-1701) inhibits wild-type BTK enzymatic activity with an EC50 of 6.70 nM in a cell-free kinase activity assay[1].
Edralbrutinib (TG-1701) (0.1-100 nM) achieves full BTK occupancy in BTK-sensitive DoHH-2 follicular lymphoma cells at a concentration of 30 nM[1].
Edralbrutinib (TG-1701) (72 h) inhibits viability of 10 parental B-NHL cell lines with a mean GI50 of 6.4 μM after 72-hour incubation, including a mean GI50 of 4.3 μM in MCL cell lines and a GI50 of 3.83 μM in REC-1 MCL cells[1].
Edralbrutinib (TG-1701) (1 μM; 24 h) at 1 μM for 24 hours impairs Ikaros signaling in BTK-sensitive REC-1 MCL cells by downregulating pBTK and MYC, upregulating YES1 (to a greater extent than ibrutinib), and inducing nuclear exclusion of Ikaros[1].
Edralbrutinib (TG-1701) (1 μM; 24 h) at 1 μmol/L for 24 hours induces nuclear exclusion of Ikaros in BTK-sensitive JEKO-1 MCL cells, reducing nuclear Ikaros levels by 50% to 70%[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Edralbrutinib (25 mg/kg; p.o.; once daily; 17 days) inhibits BTK-sensitive REC-1 MCL xenograft growth by 53% over 17 days and modulates the Ikaros signaling pathway, including reduced MYC expression and increased YES1 expression[1].
Edralbrutinib (25 mg/kg; p.o.; once daily; 17 days) does not significantly inhibit tumor growth in the noncanonical NF-κB-driven BTK inhibitor-resistant UPN-IbruR MCL xenograft model, with no associated modulation of Ikaros signaling pathway components[1].
