SP-8356, a Novel Inhibitor of CD147-Cyclophilin A Interactions, Reduces Plaque Progression and Stabilizes Vulnerable Plaques in apoE-Deficient Mice.

ABSTRACT: Interactions between CD147 and cyclophilin A (CypA) promote plaque rupture that causes atherosclerosis-related cardiovascular events, such as myocardial infarction and stroke. Here, we investigated whether SP-8356 ((1S,5R)-4-(3,4-dihydroxy-5-methoxystyryl)-6,6-dimethylbicyclo[3.1.1]hept-3-en-2-one), a novel drug, can exert therapeutic effects against plaque progression and instability through disruption of CD147-CypA interactions in apolipoprotein E-deficient (ApoE KO) mice. Immunocytochemistry and immunoprecipitation analyses were performed to assess the effects of SP-8356 on CD147-CypA interactions. Advanced plaques were induced in ApoE KO mice via partial ligation of the right carotid artery coupled with an atherogenic diet, and SP-8356 (50 mg/kg) orally administrated daily one day afte
