SF-9-2
SF-9-2 is a PD-L1/PD-1 binding inhibitor (IC50 = 24.9 nM). SF-9-2 inhibits epithelial-mesenchymal transition, migration, invasion, and proliferation of SK-N-SH cells, and also induces apoptosis and cell cycle arrest. SF-9-2 blocks PD-L1-induced SK-N-SH cell growth through the MAPK signaling pathway. SF-9-2 restores GSK-3β activity and enhances PD-L1 degradation through the ubiquitin-proteasome pathway. SF-9-2 inhibits tumor growth in the SK-N-SH NOG mouse model without significant toxicity. SF-9-2 also acts as an immune checkpoint inhibitor, blocking PD-L1 to restore T cell function. SF-9-2 can be used in neuroblastoma research.

SF-9-2 (0.5-16 μM, 48 h) exhibits significant inhibitory activity against SK-N-SH (IC50 = 5.9 μM) and SK-N-AS cells (IC50 = 8.67 μM) but has minimal inhibitory effects on SH-SY5Y and SK-N-BE (2) cells, and exhibits weak cytotoxic effects on normal cell MRC-5 (IC50 = 12.15 μM)[1].
SF-9-2 (1-6 μM, 24 h) inhibits the proliferation, migration, invasion and epithelial-mesenchymal transition (EMT), and induces mitochondria-dependent apoptosis and cell cycle arrest in SK-N-SH cells[1].
SF-9-2 (2.5-8 μM, 24-48 h) inhibits the MAPK pathway and downregulates PD-L1 Levels through targeting the ERK signaling pathway in SK-N-SH Cells[1].
SF-9-2 (2.5-5 μM, 24 h) induces PD-L1 internalization and proteasomal degradation mediated by GSK-3βin SK-N-SH Cells[1].
SF-9-2 (2.25-200 nM) decreases the fluorescence signal, effectively blocking the PD-1/PD-L1 immune checkpoint in 293T cells overexpressing PD-1 and Fc-PD-L1 protein[1].
SF-9-2 (1-16 μM, 48 h) increased the secretion level of IFN-γ in PBMCs and shows no obvious toxicity to PBMCs at concentrations of 1, 2, and 4 μM[1].
SF-9-2 (1-8 μM, 48 h) can exhibit both direct tumoricidal activity and T cell-mediated cytotoxicity against SK-N-SH cells[1].
