PAD4-IN-4
PAD4-IN-4 (compound 28) is a potent PAD4 inhibitor (IC50=0.79±0.09 μM). PAD4-IN-4 improves the tumor immune microenvironment by reshaping neutrophil phenotype, upregulating the proportions of dendritic cells and M1 macrophages, and reducing the amount of myeloid-derived suppressor cells. PAD4-IN-4 can be used for Triple-negative breast cancer research.

PAD4-IN-4 displays substantial inhibitory activity toward PAD2 and PAD4 (IC50=2.97 ± 0.29 and 0.79 ± 0.09 μM), with the best PAD4 selectivity[1].
PAD4-IN-4 suppresses the proliferation of TNBC cells in vitro (4T1 IC50: 2.39 ± 0.54 μM; MDA-MB468 IC50: 2.34 ± 0.23 μM), with relatively low toxicity toward normal breast cells (MCF-10A IC50: 8.39 ± 0.60 μM)[1].
PAD4-IN-4 (0.5, 1, 2 μM; 48 h) has enhanced antimetastasis activity for TNBC cells[1].
PAD4-IN-4 (0.5, 1, 2 μM; 48 h) is a potent PAD4 inhibitor for blocking histone citrullination and neutrophil extracellular trap (NET) formation[1].
