Effect of two andrographolide derivatives on cellular and rodent models of non-alcoholic fatty liver disease.


The prevalence of Non-Alcoholic Fatty Liver Disease (NAFLD) is increasing and there is an increasing interest in natural products to treat NAFLD. This study aimed to evaluate the hepatoprotective effect of andrographolide and two of its derivatives; in one the OH group at C-14 was removed and in the other OH groups at C-3 and C-19 were protected. Andrographolide (AN) was isolated from the aerial parts of Andrographis paniculata Wall. Isoandrographolide (IAN) and 3,19-acetonylidene andrographolide (ANA) were derivatized from AN. Drug likeness of the compounds was studied using DataWarrior. The effect of the compounds in ameliorating hepatic steatosis and lipotoxicity was assessed using palmitate-oleate induced steatotic HepG2 cell lines. In vivo efficacy of the compounds was assessed by using HFD fed rats. IAN showed comparatively high drug score and low irritability than AN. MTT assay indicated that the treatment with IAN had comparatively less toxicity than AN and ANA to HepG2 cells. The treatment with IAN significantly reduced the lipid accumulation and the leakage of LDH and transaminases, while the treatments with AN and ANA did not prohibit the leakage. In the in vivo experiment, the treatment with IAN showed comparatively better hepatoprotection by reducing the serum lipid, transaminases and ALP levels than with AN and ANA. Our results showed that IAN could be a promising lead to treat NAFLD with comparatively low toxicity and improved efficacy.
