2-Bromo 17β-Estradiol (CAS 15833-07-5)

2-Bromo 17β-estradiol is a brominated derivative of the naturally occurring estrogen, estradiol, where a bromine atom is covalently attached at the 2nd position of the estradiol molecule. This modification significantly alters its biochemical properties and interactions with estrogen receptors, making it useful in molecular biology and biochemistry research. The presence of the bromine atom introduces unique electronic and steric effects, which can influence the molecule′s binding affinity and selectivity towards estrogen receptor subtypes. In studies focusing on the estrogen receptor′s structure-activity relationship, 2-Bromo 17β-estradiol serves as a pivotal compound for elucidating the molecular dynamics and conformational changes upon ligand binding. This compound is also utilized in labeling studies to track the distribution and localization of estrogen receptors within various cell types, aiding in the understanding of estrogen-mediated signaling pathways. Through these applications, 2-Bromo 17β-estradiol contributes to a deeper insight into the regulatory mechanisms of estrogen receptors and their role in cellular functions.
