Picein
Based on 1 publication(s) in Google Scholar
Picein is an antioxidant and anti-inflammatory agent. Picein can be isolated from the leaves of Picrorhiza kurroa. Picein reduces MDA levels and increases the levels of SOD, GPX and TAC. Picein alleviates oxidative stress and promotes bone regeneration in osteoporotic bone defects by inhibiting Ferroptosis (via activation of the Nrf2/HO-1/GPX4 pathway). Picein prevents scopolamine (HY-N0296)-induced passive avoidance memory impairment in rats. Picein can be used in research related to osteoporotic bone defects and Alzheimer's disease.

In Vitro
Picein (10-80 μM; 24 h) shows no toxicity to rat bone marrow mesenchymal stem cells (BMSCs), and Picein (80 μM; 2 h pretreatment followed by 24, 48, 72 h erastin incubation) significantly restores the viability of rat BMSCs impaired by Erastin[1].
Picein (80 μM) significantly restores the viability of HUVECs impaired by Erastin[1].
Picein (80 μM; 48 h) significantly promotes M2 polarization of Raw 264.7 macrophages and reverses the inhibitory effect of 5 μM erastin[1].
Picein (for 7-21 days) significantly reverses the inhibitory effect of 5 μM erastin on osteogenic differentiation of rat bone marrow mesenchymal stem cells (BMSCs), which is verified by increased alkaline phosphatase (ALP) activity, enhanced mineralization level, and upregulated expression of osteogenesis-related proteins and genes[1].
Picein reduces ROS levels and restores mitochondrial function in neuroblastoma SH-SY5Y cells treated with Menadione (HY-B0332), indicating its potential as a neuroprotective agent[3].

Protocol for Shuttle Box Test (TDPA)
The Shuttle Box Test for TDPA, or temporally dissociated passive avoidance, measures hippocampus-dependent associative learning by testing whether a rodent avoids entering a dark compartment that was previously paired with foot shock after a temporal delay between dark-compartment entry and shock delivery. The main behavioral readout is crossover or step-through latency from the light chamber into the dark chamber; increased latency across training or retention trials reflects learned avoidance memory rather than motor performance alone.

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

Research Protocol for Inflammation-related Diseases
The NLRP3 inflammasome is a cytosolic innate immune signaling platform that integrates priming signals and danger-signal activation to promote caspase-1 activation, maturation of IL-1β and IL-18, and gasdermin D-mediated pyroptotic cell death. The core experimental logic is to determine whether inflammatory disease phenotypes are driven by increased NLRP3 expression, ASC-containing inflammasome assembly, caspase-1 cleavage, GSDMD cleavage, and extracellular release of IL-1β/IL-18 rather than by nonspecific cell injury alone. The pathway is strongly linked to inflammation-related disease phenotypes because monosodium urate crystals activate NALP3/NLRP3 inflammasome signaling in gout-like crystal inflammation, cholesterol crystals activate NLRP3 inflammasomes in atherogenesis models, and DSS-induced intestinal inflammation has been reported to involve NLRP3 inflammasome activity. However, experimental colitis studies also show context-dependent protective effects of NLRP3 inflammasome co

Ferroptosis Solutions
Ferroptosis is an iron-dependent, non-apoptotic form of regulated cell death characterized by lethal lipid peroxidation and sensitivity to suppression by iron chelators or lipophilic radical-trapping antioxidants. The core pathway links cystine uptake through system Xc−, glutathione availability, GPX4-dependent detoxification of phospholipid hydroperoxides, iron-dependent oxidative reactions, and polyunsaturated-phospholipid metabolism into a cell-death program that is biochemically and morphologically distinct from apoptosis, necrosis, and autophagy. The ferroptosis pathway is experimentally linked to phenotype through chemical and genetic perturbation. Erastin induces ferroptosis by inhibiting cystine uptake through system Xc− and weakening antioxidant defenses, while GPX4 inhibition or depletion causes lipid peroxide accumulation and ferroptotic cancer-cell death. ACSL4 and oxidizable arachidonoyl- or adrenoyl-containing phosphatidylethanolamines shape ferroptosis sensitivity by con

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.
