This study investigated the antifibrotic effect of Prosopis juliflora leaves crude methanolic extract (PJEL) against thioacetamide (TAA)-induced liver fibrosis. The phytochemical analysis of PJEL was performed via HPLC/MS in association with evaluating its free radical scavenging and cytotoxic activities. The antifibrotic activity of PJEL was assessed by dividing Wistar rats into 8 groups: normal control, PJEL1-administered rats (2 mg/ Kg b.w.), PJEL2-administered rats (4 mg/ Kg b.w.), PJEL3-administered rats (8 mg/Kg b.w.), TAA-induced hepatic fibrosis, TTA + PJEL1, TAA + PJEL2, and TAA + PJEL3. Results indicated that PJEL crude methanolic extract is rich in polyphenolic compounds and alkaloids. PJEL exerted free radical scavenging activity with IC of 123.5 μg/mL and cytotoxic activity against a well-differentiated hepatocellular cell line (IC = 11.1 μg/mL). PJEL at a dose of 4 mg/Kg b.w. ameliorated serum ALT activity and improved serum albumin level and hepatic hydroxyproline content in association with a reduction in the fibrosis stage. PJEL elevated hepatic tumor necrosis factor-α and interleukin-6 contents with less necrosis grade. PJEL post-therapy ameliorated the relative expression of Bcl-2, Col1A1, Mmp-9, and Mmp-2 genes in liver. CONCLUSION: PJEL possesses a good therapeutic activity against TAA-induced liver fibrosis via enhancing extracellular matrix removal and stimulating hepatic regeneration to decrease hepatic necrosis.
本研究旨在探讨洋麻叶粗甲醇提取物(PJEL)对硫代乙酰胺(TAA)诱导的肝纤维化的抗纤维化作用。通过 HPLC/MS 分析 PJEL 的植物化学成分,并评估其自由基清除和细胞毒性活性。通过将 Wistar 大鼠分为 8 组来评估 PJEL 的抗纤维化活性:正常对照组、PJEL1 给药组(2mg/kg b.w.)、PJEL2 给药组(4mg/kg b.w.)、PJEL3 给药组(8mg/kg b.w.)、TAA 诱导的肝纤维化组、TAA+PJEL1 组、TAA+PJEL2 组和 TAA+PJEL3 组。结果表明,PJEL 粗甲醇提取物富含多酚类化合物和生物碱。PJEL 具有自由基清除活性,IC 为 123.5μg/mL,对分化良好的肝细胞系具有细胞毒性活性(IC=11.1μg/mL)。PJEL 在 4mg/kg b.w.的剂量下可改善血清 ALT 活性,提高血清白蛋白水平和肝羟脯氨酸含量,并降低纤维化程度。PJEL 增加了肝肿瘤坏死因子-α和白细胞介素-6 的含量,且坏死程度降低。PJEL 治疗后可改善肝脏中 Bcl-2、Col1A1、Mmp-9 和 Mmp-2 基因的相对表达。结论:PJEL 通过增强细胞外基质的去除和刺激肝再生来减少肝坏死,对 TAA 诱导的肝纤维化具有良好的治疗作用。
