Anti-inflammatory, anti-oxidant and cardio-protective properties of novel fluorophenyl benzimidazole in L-NAME-induced hypertensive rats
European Journal of Pharmacology(2022)
摘要
Background
Chronic inflammation and oxidative stress play important role in development of hypertension. Recently, we have reported novel fluorophenyl benzimidazole (FPD) for vasorelaxation and antihypertensive activity in SHRs. The present study envisaged the anti-inflammatory, anti-oxidant and cardio-protective properties of FPD in L-NAME model of hypertension with special emphasis on reversal of vascular remodeling, gene expression and restoration of hemodynamic.
Methods
Antihypertensive activity of FPD was evaluated in L-NAME treated Wistar rats, and the parameters studied were anti-inflammatory activity, histomorphological changes, gene expression profile and anti-oxidant properties.
Results
FPD at 50 and 100 mg kg−1 once daily for 15 days significantly reduced SBP, DBP and MAP in L-NAME treated rats and the values were well comparable to vehicle control group. Further, FPD treatment showed a significant increase in hepatic GSH content, SOD, catalase activity, decreased MDA level and restoration of pro and anti-inflammatory cytokine levels. The mRNA expression profile of genes associated with regulation of vascular tone, remodeling and inflammation showed a significant level of alteration by chronic L-NAME treatment and was dose-dependently restored upon treatment with FPD. Further, FPD treatment restored serum lipid profile, CK, CK-MB and LDH level and also reversed the histomorphological changes like intimal wall thickening, hyperplasia of cardiomyocytes and ventricular wall thickening.
Conclusions
Taken together, FPD produced potent antihypertensive activity in L-NAME model through vasorelaxation, anti-oxidative and anti-inflammatory properties leading to restoration of serum lipid profile, cardiac biomarker, expression profile of target genes and reversal of histomorphological changes.
