Diethylstilbestrol-d4

Diethylstilbestrol-d4 is a stable isotope-labeled compound of Diethylstilbestrol (DES). DES is a synthetic non-steroidal estrogen that exerts biological effects mainly by activating the estrogen receptor (ER). DES is widely used in biomedical research to study estrogen signaling pathways, endocrine disruption, and the mechanisms of related diseases. Its in vitro activity is typically in the nanomolar to micromolar range, depending on experimental conditions and cell type. DES is commonly used in cell culture experiments to investigate its effects on cell proliferation, differentiation, and gene expression; in animal models, DES is used to evaluate its effects on the reproductive system, endocrine function, and tumorigenesis. The dose or concentration used in experiments typically depends on the experimental design and research objectives.
