Leptin, the product of the obese gene, is an adipocyte-secreted protein hormone playing a key role in the progression of obesity and hepatic steatosis. In this study, 28 novel (thio)urea and guanidine-based analogues have been synthesized and N-(1-(4-(3-(2-chloroethyl)ureido)benzyl)piperidin-4-yl)-3-(trifluoromethyl) benzamide (7i) was found to be a potent regulator of leptin expression in 3T3-L1 adipocytes. Treatment with 7i at a dose of 50 mg/kg/day for 35 days reduced the body weight and liver weight of diet-induced obesity mice by 13.5% and 18.4%, respectively, while also improving the serum levels of triglyceride, total cholesterol, leptin, adiponectin, LDL-c, HDL-c. Hematoxylin-eosin (H&E) and Oil Red O staining also confirmed that 7i ameliorated fat deposition in liver tissue and restricted the size of adipocytes in obesity-related fatty liver disease.
瘦素,作为肥胖基因的产物,是一种由脂肪细胞分泌的蛋白质激素,在肥胖症和脂肪肝的发展过程中扮演着关键角色。在本研究中,合成了28种新型(硫)脲和胍类类似物,并发现N-(1-(4-(3-(2-氯乙基)脲代)苄基)哌啶-4-基)-3-(三氟甲基)苯甲酰胺(7i)能够有效调控3T3-L1脂肪细胞中的瘦素表达。在饮食诱导的肥胖小鼠中,以每日50 mg/kg的剂量连续给药35天,可使小鼠体重和肝脏重量分别减少13.5%和18.4%,同时还能改善血清中的甘油三酯、总胆固醇、瘦素、脂联素、LDL-c、HDL-c水平。苏木精-伊红(H&E)和油红O染色也证实了7i能够减轻肝脏组织的脂肪沉积,并限制与肥胖相关的脂肪肝疾病中脂肪细胞的大小。
