Metodo per preparare il liquido master di DMSO: mg farmaco predissolto in μL DMSO ( Concentrazione del liquido master mg/mL, Vi preghiamo di contattarci prima se la concentrazione supera la solubilità del DMSO del lotto del farmaco. )

Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungereμL PEG300, mescolare e chiarire, quindi aggiungereμL Tween 80, mescolare e chiarire, quindi aggiungere μL ddH₂O, mescolare e chiarire.

Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungere μL Olio di mais, mescolare e chiarire.

Nota: 1. Si prega di assicurarsi che il liquido sia limpido prima di aggiungere il solvente successivo.
2. Assicurarsi di aggiungere il/i solvente/i in ordine. È necessario assicurarsi che la soluzione ottenuta, nellaggiunta precedente, sia una soluzione limpida prima di procedere allaggiunta del solvente successivo. Metodi fisici come il vortex, gli ultrasuoni o il bagno dacqua calda possono essere utilizzati per facilitare la dissoluzione.

Meccanismo dazione

Targets/IC₅₀/Ki	PDE2 (Cell-free assay) 6.4 μM(Ki) PDE5 (Cell-free assay) 9.5 μM(Ki) PDE4 (Cell-free assay) 11.1 μM(Ki) PDE3 (Cell-free assay) 13.9 μM(Ki) PDE1 (Cell-free assay) 15.0 μM(Ki)
In vitro	Luteolin è un flavonoide presente in Terminalia chebula, che è un inibitore non selettivo della fosfodiesterasi PDE per PDE1-5 con Ki di 15,0 μM, 6,4 μM, 13,9 μM, 11,1 μM e 9,5 μM, rispettivamente. Questo composto inibisce la produzione di TNF-alfa stimolata da LPS con un IC50 inferiore a 1 μM. Inibisce la fosforilazione di Akt indotta da LPS, così come di IkappaBalpha.
