ERD-12310A
ERD-12310A is an orally active ERα PROTAC degrader, with a Ki value of 0.95 nM against human ERα and a DC50 of 47 pM for ERα in MCF-7 cells. ERD-12310A forms a ternary complex with ERα and the CRBN E3 ubiquitin ligase, thereby inducing ubiquitination and proteasomal degradation of wild-type and ESR1Y537S mutant ERα. ERD-12310A induces tumor regression in ER+ breast cancer xenografts and inhibits tumor growth in ESR1Y537S mutant breast cancer xenografts. ERD-12310A can be used in studies related to ER-positive breast cancer and ESR1-mutant breast cancer.

In Vitro
ERD-12310A potently and efficiently degrades ERα in MCF-7 cells with a DC50 of 47 pM and Dmax of 103%, and is 10 times more potent than ARV-471[1][2].
ERD-12310A (0.3-10 nM; 4 h) potently degrades ERα in MCF-7 and T47D cells, achieving maximum degradation at 1 nM (4 h) in MCF-7 cells and 10 nM (4 h) in T47D cells[2].
ERD-12310A (10-100 nM; 7 h) degrades >80% of wild-type, ERαY537S mutant, and ERαD538G mutant ERα protein in MCF-7 cell lines at 10 nM and 100 nM following a 7 h treatment, with degradation dependent on cereblon binding[2].
ERD-12310A (5 nM; 4 h, with 2 h pretreatment of blocking agents) mediated ERα degradation in MCF-7 cells requires binding to ERα and cereblon, and is dependent on neddylation and proteasome activity[2].
ERD-12310A (0.5-500 nM; 5 h) does not significantly degrade the neo-substrate GSPT1 in MCF-7 cells at concentrations from 0.5 nM to 500 nM over 5 h, despite potently degrading ERα[2].
ERD-12310A (range of concentrations) potently inhibits MCF-7 cell growth, with activity primarily driven by ERα degradation, and shows a hook effect at 1 μM[2].
ERD-12310A binds to purified human ERα protein with a Ki of 0.95 nM[2].
ERD-12310A (1 μM; 0-60 min) has excellent stability in human, rat, and mouse liver microsomes, with a T1/2 of >60 min across all species[2].
ERD-12310A weakly inhibits most human CYP isoforms (IC50 >10 μM) and moderately inhibits CYP2B6 (IC50 = 2.5 μM) and CYP2C19 (IC50 = 6.0 μM)[2].
ERD-12310A (range of concentrations) is a very weak hERG channel inhibitor, with IC50 >10 μM and 43.7% inhibition observed at 10 μM[2].
ERD-12310A exhibits high plasma protein binding, with 98.9%, 95.7%, and 99.0% bound in human, rat, and mouse plasma, respectively[2].

Protocol
-
Patient-Derived Xenograft (PDX)
Patient-derived xenograft (PDX) models are generated by engrafting primary human tumor tissue directly into immunodeficient mice, allowing in vivo propagation of patient tumor biology without initial in vitro adaptation. These models are used to preserve key histopathological and molecular characteristics of the original tumor and enable assessment of tumor growth dynamics and therapeutic response in a living organism. The biological readout is tumor engraftment and subsequent growth in the murine host, which reflects the ability of human tumor cells to survive, vascularize, and expand in an immunocompromised microenvironment.
-
Patient-Derived Orthotopic Xenograft (PDOX)
Patient-derived orthotopic xenograft (PDOX) modeling implants fresh patient tumor tissue or patient-derived tumor cells into the anatomically corresponding organ or tissue site of immunodeficient mice, usually by surgical orthotopic implantation, to preserve patient tumor histology, local microenvironmental context, invasion, metastatic behavior, and treatment-response features better than subcutaneous implantation. PDOX readouts include tumor engraftment, orthotopic tumor growth, local invasion, metastasis, recurrence after resection, histologic similarity to the donor tumor, biomarker retention, molecular concordance, survival, and response or resistance to therapy. PDOX models are used for preclinical drug testing and individualized therapy evaluation, but engraftment success varies by tumor type and specimen quality.
-
Subcutaneous Cell-Line-Derived Xenograft
Subcutaneous cell-line-derived xenograft (CDX) models are established by implanting cultured human cancer cell lines into immunodeficient mice, where the injected cells form localized tumors that can be monitored in vivo as a measure of tumorigenic potential, growth kinetics, and treatment response. These models are widely used in oncology research because they allow reproducible tumor formation and enable comparative assessment of tumor growth between different cell lines or genetic manipulations in a controlled in vivo microenvironment. Subcutaneous implantation of cancer cells in immunodeficient mice is a standard approach for evaluating tumor growth behavior and therapeutic response across multiple cancer types, including prostate, esophageal, pancreatic, and colon cancer models.
-
Breast Cancer Modeling
Breast cancer is a heterogeneous cancer, and it has been distinguished into four subtypes: luminal A, luminal B, HER2-positive and basal-like. Molecular mutations, epigenetic alterations, hormone exposure and immune microenvironment are related to the progression of breast cancer.
-
Orthotopic Cell-Line Xenograft
Orthotopic cell-line xenograft models involve implantation of human cancer cell lines into the anatomically corresponding organ of immunodeficient mice to reproduce tumor growth within a native microenvironment, enabling more clinically relevant tumor behavior compared with subcutaneous models. These models are widely used because orthotopic placement better recapitulates tumor progression, including invasion and metastatic spread, which are often underrepresented in heterotopic implantation systems. Compared with conventional xenografts, orthotopic implantation is described as more technically complex but provides improved simulation of tumor-microenvironment interactions and metastatic behavior, making it particularly valuable for translational oncology research. Surgical orthotopic implantation approaches have been emphasized as enabling faithful reproduction of clinical cancer features, including metastasis and disease progression patterns that align with the tumor’s organ of origi
