Melittin

Synonyms: MLT, Forapin, Forapine

Melittin (MLT, Forapin, Forapine) is an activator of phospholipase A2 (PLA2) that stimulates the activity of the low molecular weight PLA2, while it does not the increase the activity of the high molecular weight enzyme.

Description Melittin (MLT, Forapin, Forapine) is an activator of phospholipase A2 (PLA2) that stimulates the activity of the low molecular weight PLA2, while it does not the increase the activity of the high molecular weight enzyme.
Targets
PLA2 [1]
In vitro
In vitro

In vitro studies using TNF-α/IFN-γ-stimulated human keratinocytes shows that melittin inhibits the increased expression of chemokines, such as CCL17 and CCL22, and pro-inflammatory cytokines, including IL-1β, IL-6 and IFN-γ, through the blockade of the NF‐κB and STAT signalling pathways.[2]
Cell Research Cell lines HaCaT cell line
Concentrations 0.1 μg/mL, 0.5 μg/mL, 1 μg/mL
Incubation Time 30 min
Method

The human keratinocyte HaCaT cell line is cultured in high glucose DMEM supplemented with 10% (v/v) FBS and antibiotics at 37°C in a humidified 5% CO2 incubator. HaCaT (5.0 × 105 cells/mL) cells are seeded in the complete medium. 24 hours later, the medium is changed to serumfree mediumwith bee venom (1, 10 and 100 ng/mL) and melittin (0.1, 0.5 and 1 μg/mL). After 30 min, the cells are stimulated with 10 ng/mL TNF-α/IFN-γ for 9 h.
In Vivo
In vivo

Melittin exhibits potent anti-atopic activities, shown by decreased Atopic dermatitis (AD)-like skin lesions, induced by DNCB in mice.[2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
