The antidiabetic effects of the methanol extract of the stem bark of (Cp) have been demonstrated in various experimental models. Besides, this extract is rich in 8-formyl-7-hydroxy-5-isopropyl-2-methoxy-3-methyl-1,4-naphthaquinone, 2,4,6-Trimethoxyphenol and vavain. However, it remains unknown whether Cp can mitigate cardiometabolic syndrome (CMS). The present study assessed the curative properties of Cp against Monosodium Glutamate (MSG)-induced CMS in rats. Male neonate Wistar rats were intraperitoneally administered with MSG (4 mg/g/day) during the first 5 days of life (postnatal days 2-6). They were kept under standard breeding conditions up to 5 months of age for the development of CMS. Diseased animals were then orally treated with atorvastatin (80 mg/kg/d) or Cp (75 and 150 mg/kg/day) for 28 days during which food intake, body mass, blood pressure, heart rate, glucose, and insulin tolerance were monitored. Plasma and tissues were collected on day 29th to assess the lipid profile, oxidative stress, and inflammatory parameters. The histomorphology of the adipose tissue was also evaluated. Cp significantly (p < 0.001) reduced the obesogenic and lipid profiles, adipocyte size, blood pressure, and oxidative and inflammatory status in MSG-treated rats. Cp also ameliorated glucose (p < 0.05) and insulin sensitivities (p < 0.001) hence, reducing animals' cardiometabolic risk score (p < 0.001). The curative effect of Cp on cardiometabolic syndrome is related to its capacity to reduce oxidative stress, inflammation, dyslipidemia, and increase insulin sensitivity. These results demonstrate the potential of Cp as a good candidate for alternative treatment of CMS.
可乐果茎皮甲醇提取物的抗糖尿病作用已在多种实验模型中得到证实。此外,该提取物富含8-甲酰基-7-羟基-5-异丙基-2-甲氧基-3-甲基-1,4-萘醌、2,4,6-三甲氧基苯酚和可可碱。然而,可乐果是否能减轻心脏代谢综合征(CMS)仍不清楚。本研究评估了可乐果对味精(MSG)诱导的大鼠心脏代谢综合征的治疗特性。雄性新生Wistar大鼠在出生后的前5天(出生后第2 - 6天)腹腔注射味精(4毫克/克/天)。它们在标准饲养条件下饲养至5个月龄以发展出心脏代谢综合征。然后对患病动物口服阿托伐他汀(80毫克/千克/天)或可乐果(75和150毫克/千克/天),持续28天,在此期间监测食物摄入量、体重、血压、心率、血糖和胰岛素耐受性。在第29天收集血浆和组织,以评估血脂谱、氧化应激和炎症参数。还评估了脂肪组织的组织形态学。可乐果显著(p < 0.001)降低了味精处理大鼠的致肥胖和血脂谱、脂肪细胞大小、血压以及氧化和炎症状态。可乐果还改善了葡萄糖(p < 0.05)和胰岛素敏感性(p < 0.001),从而降低了动物的心脏代谢风险评分(p < 0.001)。可乐果对心脏代谢综合征的治疗作用与其降低氧化应激、炎症、血脂异常以及提高胰岛素敏感性的能力有关。这些结果表明可乐果有望成为心脏代谢综合征替代治疗的良好候选药物。
