Xenoestrogen
Xenoestrogens are clinically significant because they can mimic the effects of endogenous estrogen and thus have been implicated in precocious puberty and other disorders of the reproductive system.
Estrogen and neurodegenerative diseases
Estrogen can be divided into four classes: 1) Animal Estrogens that includes estrone (E1), estradiol (E2), and estriol (E3); 2) Plant Estrogens (Phytoestrogens); 3) Fungi Estrogens (Mycoestrogens) and 4) Synthetic Estrogens (xenoestrogens). Xenoestrogens contain a large number of compounds that are synthesized or naturally exist. These estrogens imitate estrogen structure and can be designed to satisfy the need of new drugs. They may have a significant impact on neurodegenerative disease treatment due to their ease of synthesis and targeted specificity.
