Description:

WARNING: This product is for research use only, not for human or veterinary use.

PaPE-1 is a pathway Preferential Estrogen, activating the extranuclear signaling pathway without activity on the nuclear signaling pathway. PaPE-1 elicited anti-apoptotic effects by inhibiting Aβ-induced caspase activities as well as attenuating apoptotic chromatin condensation, and in these ways, PaPE-1 prevented neuronal cell death. Posttreatment with PaPE-1 also downregulated the Aβ-affected mRNA expression of apoptosis-specific factors, such as Bax, Gsk3b, Fas, and Fasl, except for Bcl2, which was upregulated by PaPE-1.

More Info
Alzheimer's disease (AD) is a multifactorial and severe neurodegenerative disorder characterized by progressive memory decline, the presence of Aβ plaques and tau tangles, brain atrophy, and neuronal loss. Available therapies provide moderate symptomatic relief but do not alter disease progression.
Product Data
Biological target:
PaPE-1 activates the extranuclear signaling pathway without activating the nuclear signaling pathway. PaPE-1 bound 50,000-fold less well to ERα and Erβ estrogen receptors. PaPE-1 activated extranuclear-initiated ER-regulated genes, but showed essentially no activation of nuclear-initiated estrogen receptor (ER) gene targets such as the progesterone receptor.
In vitro activity:
PaPE-1 is a potential therapy that targets non-nuclear ERs for Alzheimer's disease (AD). In a cellular model of AD, PaPE-1 reduced Aβ-induced neurotoxicity, oxidative stress, and apoptosis. While its role in controlling the external apoptotic pathway is debated, PaPE-1 notably restored mitochondrial function, suggesting its anti-AD mechanism primarily targets mitochondrial apoptosis. Reference: Neurotox Res. 2020 Dec;38(4):957-966. https://pubmed.ncbi.nlm.nih.gov/33025361/
In vivo activity:
In a mouse Alzheimer's disease (AD) model, PaPE-1 posttreatment reduced neurodegeneration, restored neurite growth, and inhibited AD-related gene expression. Following 24 h of exposure, PaPE-1 inhibited Aβ-evoked effects, demonstrated by reduced parameters of neurotoxicity, oxidative stress, and apoptosis.
