Solasodine (Purapuridine, Solancarpidine, Solasodin, Salasodine, Salasdine) is a poisonous alkaloid chemical compound that occurs in plants of the Solanaceae family. Solasodine reduces the mRNA level of matrix metalloproteinase-2 (MMP-2), MMP-9 and extracellular inducer of matrix metalloproteinase (EMMPRIN), but increases the expression of reversion-inducing cysteine-rich protein with kazal motifs (RECK). Solasodine downregulates oncogenic microRNA-21 (miR-21), which has been known to target RECK. Solasodine also reduces PI3K/Akt signaling pathways and downregulates expression of miR-21.
