Abstract

Hyperlipidemia is a serious disorders affecting the metabolism of fats in the human body, and it is usually associated with some serious cardiovascular complications increasing the risk for sudden death. Tranilast (TRN) (N-[3’,4’-dimethoxycinnamoyl]-anthranilic acid) is an analog of a tryptophan metabolite. Initially, tranilast was identified as an anti-allergic agent, and used in the treatment of inflammatory diseases, such as bronchial asthma, atypical dermatitis, allergic conjunctivitis, keloids and hypertrophic scars. Nifuroxazide (NFR) is an oral nitrofuran antibiotic that has long been used for management of diarrhea and recently various recent out merging valuable therapeutic impacts were reported. The current study sought the concept of repositioning nifuroxazide in management of hyperlipidemia. Hyperlipidemia was induced in male rabbits using cholesterol enriched diet for 9 weeks and starting from the beginning of 5th week ; TRN (30 and 100 mg/kg) and NFR (100 and 300 mg/kg) were administered once daily for the further 5 weeks ; till the end of the 9th week of the experiment. TRN and NFR significantly recovered balanced lipid profile as serum cholesterol, total glycerides, LDL significantly declined with significant elevation in serum HDL. Meanwhile, serum LDH, CK, ALT and AST activities were significantly corrected. These biochemical changes were correlated with significant improvement in the histopathological examination of hepatic, cardiac and aortic specimen with decreased expression of CD68 and Ki67 in the myocardium and the aorta implying retraction in macrophages’ infiltration and tissue regeneration. Myocardial specimen confirmed significant recovery with preservation of cardiac muscle fibers. Aortic specimen confirmed retraction in the aortic thickness and fewer deposition of fat globules. In conclusion, TRN and NFR attenuated experimentallyinduced hyperlipidemia with significant recovery of serum profile and tissue necrotic changes. The histopathological examination of hepatic, myocardial and aortic specimen confirmed the onset of tissues’ recovery alongside biochemical improvement.
