Methode voor het bereiden van in vivo formulering: Neem μL DMSO mastervloeistof, voeg vervolgens toe μL Maïsolie, mengen en helder maken.

Opmerking: 1. Zorg ervoor dat de vloeistof helder is voordat u het volgende oplosmiddel toevoegt.
2. Zorg ervoor dat u het/de oplosmiddel(en) in de juiste volgorde toevoegt. U moet ervoor zorgen dat de verkregen oplossing, bij de vorige toevoeging, een heldere oplossing is voordat u verdergaat met het toevoegen van het volgende oplosmiddel. Fysische methoden zoals vortexen, echografie of een warmwaterbad kunnen worden gebruikt om het oplossen te bevorderen.

Werkingsmechanisme

Targets/IC₅₀/Ki	TLR7 TLR8
In vitro	Resiquimod (R-848) activeert immuuncellen en induceert proliferatie van wild-type miltcellen via de Toll-like receptor 7 (TLR7)-MyD88-afhankelijke signaalroute. Deze verbinding moduleert ook dendritische cellen om cytomegalovirus- en HIV-1-specifieke T-celresponsen te versterken. Het induceert de differentiatie van myeloïde suppressorcellen naar macrofagen en dendritische cellen, en kan kankerimmunotherapie verbeteren door immunosuppressieve MDSC's te verminderen.
In vivo	Bij wild-type muizen induceert Resiquimod (R-848) (50 nmol, i.p.) verhoogde serumconcentraties van IFN-alpha, TNF-alpha en IL-12, terwijl noch TLR7-deficiënte muizen, noch MyD88-deficiënte muizen een toename van deze cytokines vertonen. In een muismodel van allergische astma vermindert deze verbinding (i.n., 20 μg/muis) allergeen-geïnduceerde luchtwegreactiviteit en ontsteking via reductie van Nrf2-signalering.
