P110 heptapeptide
Based on 1 publication(s) in Google Scholar
P110 heptapeptide is a peptide inhibitor of the Drp1-Fis1 interaction. P110 heptapeptide has anti-inflammatory, immunomodulatory, mitochondrial protective, and neuroprotective activities. Without blocking the physiological functions of Drp1, P110 heptapeptide reduces pathological functions in many models of neurodegeneration, ischemia, and sepsis. P110 heptapeptide can be used for research on neurological and inflammatory diseases.

Biological Activity
Description
In Vitro
P110 heptapeptide (2 μM; 16-24 h) inhibits Drp1-Fis1 interaction, suppresses mitochondrial fragmentation and ROS production, prevents mitochondrial membrane potential decline, and maintains mitochondrial size and morphology in LPS (HY-D1056)-treated H9c2 cardiac myocytes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. Further protocols information, click here.
In Vivo
P110 heptapeptide (loaded into macrophage-derived exosomes; tail vein injection; single dose) significantly alleviates cerebral ischemia-reperfusion injury, reduces infarct size, and improves neurological function in male rats with transient middle cerebral artery occlusion[3].

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5 mg/mL (6.61 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

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.

LPS-Induced Endotoxemia/Systemic Inflammation
Lipopolysaccharide (LPS)-induced endotoxemia is a widely used in vivo model of acute systemic inflammation in which LPS, a Gram-negative bacterial endotoxin, activates innate immune signaling primarily through TLR4, leading to rapid and transient induction of pro-inflammatory cytokines such as TNF-α, IL-6, and IL-1β in circulation and tissues. This cytokine surge is commonly used as a measurable readout of systemic inflammatory activation and immune dysregulation, and is typically assessed within hours after intraperitoneal LPS administration in mouse models of endotoxemia. The model captures key features of systemic inflammatory response syndrome, including cytokine release, immune cell activation, and downstream tissue responses, and has been used to evaluate anti-inflammatory interventions such as cytokine modulation, lipid mediators, and immune cell-targeting therapies.

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
