脂联素是一种具有胰岛素敏感作用的脂联素,分泌自脂肪细胞,以高、中和低分子量形式(HMW、MMW和LMW)进入循环。 HMW脂联素寡聚体具有最强的胰岛素敏感活性。 WSF-P-1(N-甲基-1,2,3,4,5,6-六氢-1,1,5,5-四甲基-7H-2,4α-甲基萘烯-7-胺)是通过化学修饰从天然倍半萜长叶烯中提取的。本研究发现WSF-P-1可以激活3T3-L1脂肪细胞和293T细胞中的AMPK。WSF-P-1通过激活AMPK促进HMW脂联素的组装,并增加3T3-L1脂肪细胞中HMW /总脂联素比例。我们证明了钙依赖性CaMKK信号通路参与了WSF-P-1诱导的AMPK激活和脂联素多聚化。 WSF-P-1还可以激活3T3-L1脂肪细胞中的GLUT1介导的葡萄糖摄取,使其成为治疗2型糖尿病、肥胖症和其他与肥胖相关的代谢疾病的潜在药物候选物。
Adiponectin, an adipokine with insulin-sensitizing effect, is secreted from adipocytes into circulation as high, medium, and low molecular weight forms (HMW, MMW, and LMW). The HMW adiponectin oligomers possess the most potent insulin-sensitizing activity. WSF-P-1(N-methyl-1,2,3,4,5,6-hexahydro-1,1,5,5-tetramethyl-7H-2,4α-methanonaphthalen-7-amine) is derived from natural sesquiterpene longifolene by chemical modifications. We found that WSF-P-1 activates AMPK in both 3T3-L1 adipocytes and 293T cells in this study. Activation of AMPK by WSF-P-1 promotes the assembly of HMW adiponectin and increases the HMW/total ratio of adiponectin in 3T3-L1 adipocytes. We demonstrated that the Ca2+-dependent CaMKK signaling pathway is involved in WSF-P-1-induced AMPK activation and adiponectin multimerization. WSF-P-1 also activates GLUT1-mediated glucose uptake in 3T3-L1 adipocytes, making it a potential drug candidate for the treatment of type 2 diabetes, obesity, and other obesity-related metabolic diseases.
