摘要
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 after carotid artery ligation for three weeks. The anti-atherosclerotic effect of SP-8356 was assessed using histological and molecular approaches. SP-8356 interfered with CD147-CypA interactions and attenuated matrix metalloproteinase-9 activation. Moreover, SP-8356 induced a decreased in atherosclerotic plaque size in ApoE KO mice and stabilized plaque vulnerability by reducing the necrotic lipid core, suppressing macrophage infiltration, and enhancing fibrous cap thickness through increasing the content of vascular smooth muscle cells. SP-8356 exerts remarkable anti-atherosclerotic effects by suppressing plaque development and improving plaque stability through inhibiting CD147-CypA interactions. Our novel findings support the potential utility of SP-8356 as a therapeutic agent for atherosclerotic plaque.
