ETN029
Based on 1 Customer Validation
ETN029 (MC339) is a selective DLL3 ligand. ETN029 labeled with 225Ac has dose-dependent cytotoxicity in SCLC, NEPC and metastatic melanoma cells and increases the phosphorylation of H2AX expression. ETN029 labeled with 177Lu shows rapid uptake persistent tumor retention and favorable tumor-to-kidney ratio. ETN029 can be used for cancers like SCLC and NEPC imaging and research.

Biologische Aktivität
ETN029 (MC339) binds human DLL3 with picomolar affinity and specificity, showing high cell binding and internalization in both SHP-77 and transgenic CT26.DLL3 cell lines, with minimal binding to DLL3-negative CT26.WT controls[3].
[225Ac]Ac-ETN029 exhibits dose-dependent cytotoxicity in SCLC, NEPC, and metastatic melanoma cell lines and increases the phosphorylation of H2AX, a marker for DNA double-strand breaks[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In CDX models (NCI-H69, SHP-77), a single dose of [225Ac]Ac-ETN029 (0.35-1.4 µCi) resulted in robust tumor regression and prolonged survival[3].
