Compound guide

PINEALON

A pathway-focused guide to molecular mechanisms, published evidence, and the limits of interpretation.

Overview

A Summary:PINEALON

Pinealon is the research name for the tripeptide Glu–Asp–Arg, abbreviated EDR. The selected studies examine oxidative stress in cells and a specific rat developmental-stress model.

Reported responses include reactive oxygen species, cell viability and the timing of ERK1/2 activation. No single validated receptor target is established by these findings.

Cell observations and a prenatal hyperhomocysteinemia rat model do not establish human cognitive improvement, safety or clinical efficacy. The studies also do not identify the composition or properties of this catalog vial.

Research model

Cellular & MolecularHow PINEALON Is Studied

These receptors, enzymes, and signaling networks define the primary laboratory questions associated with this research material.

01Reactive oxygen species and viability

Oxidative-stress model

At the cellular or molecular level

A cell study reported changes in ROS accumulation and necrotic cell death in stressed cerebellar granule cells, neutrophils and PC12 cells.

02Associated signaling observations

ERK / cell-cycle response

At the cellular or molecular level

The same study reported altered ERK1/2 activation timing and cell-cycle behavior. These associations do not demonstrate direct binding to ERK, DNA or a specific receptor.

03Behavior and neuronal stress endpoints

Rat prenatal-stress model

At the cellular or molecular level

A rat study of prenatal hyperhomocysteinemia assessed offspring learning-related behavior and isolated neuronal stress responses. Its developmental and disease-model context is essential.

Map the research pathway

From target to research question

Follow each target through its intracellular signal, the model being observed, and the evidence boundary that governs interpretation.

01

Oxidative-stress model

Reactive oxygen species and viability

A cell study reported changes in ROS accumulation and necrotic cell death in stressed cerebellar granule cells, neutrophils and PC12 cells.

Reactive oxygen species and viability

ROS assays and propidium-iodide cell-death measurements; a lower signal does not identify a direct receptor.

Interpret with limits

Pathway activity does not establish safety, efficacy, or suitability for personal use.

02

ERK / cell-cycle response

Associated signaling observations

The same study reported altered ERK1/2 activation timing and cell-cycle behavior.

Associated signaling observations

ERK activation time course and cell-cycle measurements; the direct-target mechanism remains uncertain.

Interpret with limits

Pathway activity does not establish safety, efficacy, or suitability for personal use.

03

Rat prenatal-stress model

Behavior and neuronal stress endpoints

A rat study of prenatal hyperhomocysteinemia assessed offspring learning-related behavior and isolated neuronal stress responses.

Behavior and neuronal stress endpoints

Spatial-learning tasks plus neuronal ROS and cell-death readouts; species and developmental context constrain translation.

Interpret with limits

Pathway activity does not establish safety, efficacy, or suitability for personal use.

Research interpretation

How to read the pathway.

01

Reactive oxygen species and viability

The measurements concern cellular stress and survival under specified laboratory conditions.

02

Associated signaling observations

A downstream signaling change is a clue about a response, not proof of the molecule’s first target.

03

Behavior and neuronal stress endpoints

Behavior in this specialized animal model is not evidence of a human memory benefit.

Evidence boundary

Cell observations and a prenatal hyperhomocysteinemia rat model do not establish human cognitive improvement, safety or clinical efficacy. The studies also do not identify the composition or properties of this catalog vial.
