BRAFV600-mutant melanoma short-term cultures 2 μM 4 days To verify the resistance of MITF-low/NF-κB-high melanoma short-term cultures to RAF and MEK inhibitors. Cancer Discov. 2014 Jul;4(7):816-27.
BRAFV600-mutant melanoma cell lines 2 μM 4 days To assess the sensitivity of BRAFV600-mutant melanoma cell lines to the RAF inhibitor PLX4720, finding that MITF-high cell lines were sensitive to PLX4720, while MITF-low/NF-κB-high cell lines were resistant. Cancer Discov. 2014 Jul;4(7):816-27.
ER3 1.2 μM 16 h To evaluate the effect of Bemcentinib on autophagic flux in ER3 cells, results showed that Bemcentinib significantly reduced the starvation-induced degradation of long-lived proteins, indicating the blockage of autophagic flux. J Thorac Oncol. 2020 Jun;15(6):973-999.
HCC827 0.8 μM 24 h To investigate the effect of Bemcentinib on autophagic flux in HCC827 cells, results showed that Bemcentinib treatment increased the numbers of LC3A/B-positive autophagosomes and lysosomes, indicating the blockage of autophagic flux. J Thorac Oncol. 2020 Jun;15(6):973-999.
344SQ_Z-cad cells 2 μM 72 h Bemcentinib specifically killed GFP+ mesenchymal cells, while selumetinib specifically killed RFP+ epithelial cells.

MCF-7/ADR cells 1 µM 24 h To evaluate the inhibitory effect of R428 on Axl activity and its impact on the expression of epithelial and mesenchymal markers in MCF-7/ADR cells. Results showed that R428 significantly inhibited Axl activity and reduced the expression of mesenchymal markers N-cadherin and Vimentin. Theranostics. 2016 May 24;6(8):1205-19.
BaF3-EpoR-JAK2V617F cells 0.5, 1, 2, 3, 4, 5 µM 48 h To assess the effect of Bemcentinib on the viability of BaF3-EpoR-JAK2V617F cells, the results showed that Bemcentinib significantly reduced cell viability. Hemasphere. 2021 Aug 11;5(9):e630.
SET-2 cells 0.5, 1, 2, 3, 4, 5 µM 48 h To assess the effect of Bemcentinib on the viability of SET-2 cells, the results showed that Bemcentinib significantly reduced cell viability. Hemasphere. 2021 Aug 11;5(9):e630.
BMDCs 40 nM 24 h BGB324-treated BMDCs showed increased secretion of IFN-b, indicating that Axl inhibition promotes type I interferon production. Cell Rep Med. 2022 Mar 15;3(3):100554.
PC9 cells 100 nM 7 days To assess cell viability, the results showed that Bemcentinib inhibited the viability of PC9 cells. Cell Rep Med. 2024 Sep 17;5(9):101703.
