EGX358
EGX358 is a selective, orally active estrogen receptor β (ERβ) agonist with an EC50 of 27.4 nM for ERβ. EGX358 enhances object recognition ability, spatial memory and memory consolidation, and attenuates drug-induced vasomotor responses. EGX358 alleviates partial uterine atrophy without inducing uterine hypertrophy, while it does not alter anxiety-like behavior, depression-like behavior or body weight. EGX358 can be used in research related to Alzheimer's disease and menopause.

Biological Activity

ERβ 27.4 nM (EC50) |
EGX358 potently activates ERβ with an EC50 of 27.4 nM, and exhibits 750-fold selectivity for ERβ over ERα[1].
EGX358 shows 750-fold higher selectivity for ERβ than for ERα, and exhibits no off-target activity against a panel of other nuclear receptors[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
EGX358 (oral administration; once daily; for 64 consecutive days) reduces senktide-induced elevation of tail skin temperature in ovariectomized mice, enhances their spatial recognition and object recognition memory, without altering body weight, anxiety-like or depression-like behaviors of the mice, nor affecting the expression/phosphorylation levels of brain proteins[3].
EGX358 (10 mg/kg; p.o.; once daily; for 8 weeks) significantly enhances object recognition memory in ovariectomized EFAD mouse models of Alzheimer's disease[4].
EGX358 (0.5 mg/kg; p.o.; once daily; for 64 days) reduces senktide-induced vasodilation, improves spatial recognition memory and object recognition memory in young ovariectomized mice, and exerts no adverse effects on mouse body weight, anxiety-like behavior or depression-like behavior[2].

Animal Model:APOE-TR+/+/5xFAD+/− (EFAD) (female, ovariectomized at 5 months of age; homozygous for human APOE3 (E3FAD) or heterozygous for human APOE3 and APOE4 (E3/4FAD))[1]
-
Dosage:10 mg/kg
-
Administration:p.o.; daily; 8 weeks
-
Result:Enhanced object recognition memory in both genotypes but did not improve object placement memory.
Reduced tail-skin temperature elevation in E3FAD mice but not in E3/4FAD mice.
Did not affect anxiety-like behavior or body weight; slightly increased uterine weight without causing hypertrophy.

Dosage:0.5 mg/kg
-
Administration:p.o.; daily; 64 days
-
