Transferrin Receptor Activator

Apo-Bovine Transferrin refers to iron free Transferrin (HY-P3267), serves as Transferrin receptor ligand and mediates iron release from endothelial cells. Apo-Transferrin can directly bind to hephaestin, which can convert Fe²⁺ to Fe³⁺. Apo-Transferrin mediates iron efflux most likely in cooperation with ferroportin 1. Apo-Bovine Transferrin can be used in neuroretinal research.

DIM-3,5-Cl2 is an inverse NR4A1/NR4A2 agonist with K_D values of 7.7 μM and 12.0 μM for NR4A1 and NR4A2, respectively. DIM-3,5-Cl2 acts as an inverse agonist to downregulate pro-oncogenic and proendometriotic gene products, and as an agonist to enhance NR4A1/2/Sp1/Sp4-mediated CD71 transactivation. DIM-3,5-Cl2 induces ferroptosis via ROS formation, lipoperoxidation, MDA production, and reduced GPX4, SLC7A11 expression. DIM-3,5-Cl2 induces apoptosis via PARP and caspase-3 cleavage, reduced BCL-2 expression, and inhibits cancer cell viability. DIM-3,5-Cl2 can be used for the research of triple negative breast cancer, endometriosis, and colorectal cancer.

HDAC11-IN-3 (Compound A9) is a selective HDAC11 inhibitor (IC₅₀: 4.1 nM). HDAC11-IN-3 has inhibitory effects on U937 and OCI-AML2 acute myeloid leukemia (AML) cell lines (IC₅₀: 10 μM). HDAC11-IN-3 has significant anti-AML activity, inducing apoptosis, cell cycle arrest, and differentiation. HDAC11-IN-3 upregulates the iron transporters transferrin (TF) and transferrin receptor (TFRC), and activates the p62-Keap1-Nrf2-HMOX1 pathway, which together lead to increased intracellular iron levels and induce ferroptosis in AML cells. HDAC11-IN-3 can be used alone or in combination with Cytarabine (HY-13605) for AML research.

PROTAC FSP1 degrader 1 is a highly efficient and selective PROTAC degrader targeting FSP1. PROTAC FSP1 degrader 1 significantly induces the accumulation of intracellular lipid peroxides. PROTAC FSP1 degrader 1 exhibits synergistic induction of ferroptosis with GPX4 inhibitors. PROTAC FSP1 degrader 1 can induce ROS production. PROTAC FSP1 degrader 1 upregulates the mRNA expression of ferroptosis-related proteins (GPX4, FTH1, ACSL4, TfR1, FSP1). PROTAC FSP1 degrader 1 can be used for the study of triple-negative breast cancer.
