Estrogen receptor Inhibitor

Estrogen receptor-IN-2 is a potent estrogen receptor inhibitor formed by the conjugation of Tam (HY-13757)-NHC and gold (I). Estrogen receptor-IN-2 significantly downregulates estrogen receptor (ER) levels, inhibits ER-mediated downstream signaling pathways, and induces immunogenic cell death (ICD) mediated by damage-associated molecular patterns (DAMPs). Estrogen receptor-IN-2 can overcome drug resistance in MCF-7^Y537S mutant cells via the RAMP3/CALCR signaling pathway. It is suitable for research on endocrine-resistant breast cancer.

Regaloside C is an anti-inflammatory agent and antioxidant that scavenges ABTS and DPPH free radicals. Regaloside C targets multiple molecules including TNF-α, MMP-2, ERα, AKT1, TLR4 and HSP90-α. Regaloside C is applicable to research related to inflammatory diseases.

2-Hydroxyestrone (Catecholestrone) is a specific receptor-mediated antiestrogenic agent. 2-Hydroxyestrone is anticarcinogenic.

CS-1-103 is a potent estrogen receptor (ER) TRACER (transcriptional regulation via active control of epigenetic reprogramming). CS-1-103 inhibits ER transcriptional activity with an EC₅₀ of 0.36 μM by recruiting methyl-CpG binding domain protein 2 (MBD2), HDACs and the nucleosome remodeling and deacetylase (NuRD) complex. CS-1-103 can be used for breast and prostate cancer research.
