SX-682 is a novel CXCR1/2 inhibitor (IC50s: CXCR1 = 42 nM, CXCR2 = 20 nM).1?It displayed robust synergistic activity with immune checkpoint blockade against castration resistant prostate cancer.2 It significantly reduced tumor burden in a Ptenfl/fl/Lkb1fl/fl mouse model of lung squamous cell cancer when used in combination with anti-PD1 therapy.3 SX-682 significantly inhibited trafficking of neutrophilic myeloid-derived suppressor cells (PMN-MDSCs) enhancing anti-PD1 immune checkpoint blockade, T cell-based immunotherapy, and NK-cell immunotherapy.4,5 | [storage]
