SP-8356

SP-8356, an anti-inflammatory synthetic Verbenone derivative, is a potent, orally active cluster of differentiation 147 (CD147) inhibitor. SP-8356 inhibits CD147-cyclophilin A (CypA) interaction and reduces MMP-9 activity. SP-8356 exerts anti-breast cancer effects by inhibiting NF-κB signaling. Anti-atherosclerotic effects[1][2][3].

SP-8356 (5-10 μM; 48 hours) inhibits growth of various types of breast cancer cell lines in a time- and dose-dependent manner[1].SP-8356 (10 μM; 48 hours) increases percentage of MDA-MB231 cells in S phase and decreases casapas-3 and cleaved PARP[1]. Cell Proliferation Assay[1] Cell Line: MDA-MB231, MDA-MB453, 4T1, and MCF-7 cells

SP-8356 (10 mg/kg; i.p.; every three days until the 42nd day) inhibits tumor growth in a xenograft mouse model[1].SP-8356 (50 mg/kg; p.o.; daily one day after carotid artery ligation for three weeks) prevents the formation of plaque and attenuates its vulnerability[2]. Animal Model: Five-week-old female NOD/SCID mice (MDA-MB231 xenografts)[1]
