HY-N6710S

α-Zearalenol-d4
α-Zearalenol-d4 is a deuterated labeled α-Zearalenol . α-Zearalenol is a Mycotoxin with high affinity for the estrogen receptors (ER), α-Zearalenol is the derivative of zearalenone (ZEN), causes reproductive disorders in animals, due to its xenoestrogenic effects .

HY-13636S

Fulvestrant-d3
Fulvestrant-d₃ is the deuterium labeled Fulvestrant. Fulvestrant (ICI 182780) is a pure antiestrogen and a potent estrogen receptor (ER) antagonist with an IC₅₀ of 9.4 nM. Fulvestrant is also a GPR30 agonist. Fulvestrant effectively inhibits the growth of ER-positive MCF-7 cells with an IC₅₀ of 0.29 nM. Fulvestrant also induces autophagy and has antitumor efficacy .

4,4'-Sulfonyldiphenol-d8

1 Publications Verification

4,4'-Sulfonyldiphenol-d₈ (Bisphenol S (4,4'-Sulfonyldiphenol)-d₈) is the deuterium labeled 4,4'-Sulfonyldiphenol (HY-W011927).4,4'-Sulfonyldiphenol (Bisphenol S; Bis(4-hydroxyphenyl) sulfone), a substitute for Bisphenol A (HY-18260), is widely used in industrial and consumer products. 4,4'-Sulfonyldiphenol is an estrogen receptor (ER) agonist and can competitively bind to thyroid hormone receptors (TR) with IC₅₀ values for TRα and TRβ are 2650 μM and 2294 μM respectively, thereby affecting breast development and reducing the expression of androgen receptor (AR) in fetal testes. 4,4'-Sulfonyldiphenol promotes the progression of glioblastoma by upregulating the EZH2 mediated PI3K/AKT/mTOR pathway. Under chronic exposure, 4,4'-Sulfonyldiphenol can cause significant lipid deposition and dyslipidemia in the mouse liver by upregulating JunB and Atf3, and has a role in causing obesity at low doses. 4,4'-Sulfonyldiphenol induces intestinal inflammation by altering the intestinal microbiome. 4,4'-Sulfonyldiphenol accelerates the progression of atherosclerosis in zebrafish embryo larvae.

HY-19822S3

Elacestrant-d6
Elacestrant-d₆ (RAD1901-d₆) is a deuterated labeled Elacestrant (HY-19822). Elacestrant is a selective estrogen receptor (estrogen *receptor*, ER) degrader (SERD) with oral activity, with IC₅₀ values of 48 and 870 nM for ERα and ERβ, respectively. Elacestrant can also effectively inhibit the growth of ER ⁺ breast cancer cell lines both in vitro and in vivo.
