H1650 and H1975Non-small cell lung cancerEvodiamine (0, 2, 4, 8, 16 μM; 24 h) suppressed IFN-γ-induced PD-L1 expression in H1975 and H1650 cells. MUC1-C mRNA and protein expression were decreased by evodiamine (0, 2, 4, 8, 16 μM; 24 h) in NSCLC cells as well. Evodiamine (0, 2, 4, 8, 16 μM; 24 h) downregulated the PD-L1 expression and diminished the apoptosis of T cells. It inhibited MUC1-C expression and potentiated CD8+ T-cell effector function.Elevating CD8+ T cells and downregulating the MUC1-C/PD-L1 signaling pathway[94]
A549, H460, H1299, and H1650Non-small cell lung cancerThe cells were treated with evodiamine (3 μM), erlotinib (20 μM), or the combination for 48 h. Combining evodiamine with erlotinib successfully inhibited cell proliferation and survival in wild-type EGFR NSCLC cells, characterized as erlotinib-resistant. In addition, evodiamine plus erlotinib significantly increased the apoptotic rate (61.86%) of NSCLC cells, as compared to single-agent treatment alone (evodiamine ∼33.71%; erlotinib ∼21.92%).mTOR/S6K1- mediated downregulation of Mcl-1[95]
Caco-2 and HT-29Colorectal adenocarcinomaEvodiamine (10 μM) enhanced the effect of berberine (0, 2.5, 5, 10, 20, 40 μM) on cell viability with IC50 values ranging from 38.85 μM to 15.82 μM in Caco-2 cells at 24 h, but evodiamine did not have this effect in HT-29 cells.Attenuating the overexpression of P-gp gene[96]
