Dehydroevodiamine
Based on 3 publication(s) in Google Scholar
Dehydroevodiamine is a blood-brain barrier-permeable, orally effective AChE and BACE1 inhibitor (IC50 = 40.96 μM). Dehydroevodiamine is isolated and extracted from Evodia rutaecarpa. Dehydroevodiamine attenuates neurotoxicity through multiple targets by inhibiting BACE1 to block Aβ production, inhibiting AChE activity, scavenging ROS, and suppressing calcium influx. Dehydroevodiamine can be used for research on Alzheimer's disease, cerebral ischemia, vascular dementia, and other cognitive disorder-related diseases.

Protocols
-
Neurotoxicity Study
This protocol assesses in vitro neurotoxicity by combining neuronal viability, mitochondrial/metabolic activity, neurite outgrowth, and optional neuronal network function readouts. Calcein-AM or resazurin/PrestoBlue readouts estimate viable or metabolically active cells; βIII-tubulin immunofluorescence detects neuronal morphology and neurite networks; TMRE detects mitochondrial membrane potential; and MEA recordings detect functional changes in neuronal network activity.
-
Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
-
ROS/oxidative-stress fluorescent staining
ROS/oxidative-stress fluorescent staining uses cell-permeant fluorogenic probes that become fluorescent after oxidation inside cells or tissues; commonly used examples include DCFH-DA/DCFDA for broad cellular oxidant detection, DHE for superoxide-related signal detection, MitoSOX for mitochondrial superoxide-related signal detection, and CellROX probes for oxidative-stress-associated fluorescence readouts. The assay detects probe oxidation rather than a single ROS species unless the probe and analysis method have been chemically validated for that species. DCFH-DA enters cells, is deacetylated by intracellular esterases to DCFH, and produces fluorescent DCF after oxidation, so the readout is used as an operational measure of total cellular oxidative stress rather than a species-specific ROS measurement. DHE and MitoSOX can report superoxide-related oxidation, but red fluorescence alone can include non-specific ethidium-like oxidation products; HPLC or optimized spectral approaches are
-
Ca2+ Staining Technique
Ca2+ staining is an experimental technique that utilizes specific fluorescent probes (such as Fluo-4 AM, Fura-2, etc.) to qualitatively or quantitatively detect dynamic changes in intracellular Ca2+ concentrations; this is achieved by monitoring the changes in fluorescent signals generated when these probes bind to free intracellular calcium ions. The underlying principle relies primarily on the presence of chelating groups within the probe's molecular structure that possess high affinity for calcium ions.

Alzheimer’s Disease Modeling
Alzheimer’s Disease (AD) is a neurodegenerative disorder characterized by a progressive decline in cognitive functions and loss of specific types of neurons and synapses. Alzheimer's symptoms can be simulated in mice by injecting drugs (such as Aβ) or genetically modified.
