Description

General description

Aristolochic acid is a naturally occurring plant metabolite found in Aristolochia sp, Bragantia sp. or Asarum sp. plants.[1] It comprises a mixture of nitrophenanthrene carboxylic acids such as aristolochic acid I and II.[2]

Application

Aristolochic acid I have been used:

• as a standard for the analysis of Aristolochia sprucei crude extract by high-performance liquid chromatography[3]
• to study its effects on histone deacetylase 3 (HDAC3) aberration and renal fibrosis[4]
• to induce acute aristolochic acid nephropathy and to study its impact on miRNA and mRNA expression in mice[5]

Biochem/physiol Actions

Aristolochic acid is a potent inhibitor of phospholipase A2 (PLA2), hyaluronidase, and acetylcholinesterase plasma proteases from snake venoms.[6] Aristolochic acid is considered a herbal medicine and shows therapeutic effects against obstetrics, snake bites, gout, and rheumatism.[2] It exhibits anti-inflammatory and anti-malarial properties.[7] In addition, it is also considered a genotoxic mutagen[2] and causes aristolochic acid nephropathy (AAN), characterized by interstitial fibrosis and urothelial cancer.[2]

Potent phospholipase A₂ inhibitor, including calcium ionophore-induced phospholipase A₂ activity in neutrophils. Kidney tumor initiator in experimental animal model.
