Aristolochic acids are a family of carcinogenic, mutagenic, and nephrotoxic compounds commonly found in the plant family Aristolochiaceae, including Aristolochia and Asarum (wild ginger), which are commonly used in Chinese herbal medicine. Aristolochic acid I is the most abundant of the aristolochic acids and is found in almost all Aristolochia species. Aristolochic acids are often accompanied by aristolactams.
The aristolochic acids are among a group of substituted 10-nitro-1-phenantropic acids, biogenetically derived from benzylisoquinoline precursors, which in turn originate from tyrosine. The biosynthesis of aristolochic acid therefore begins at tyrosine (2), which is converted to dopa (3). Dopa is subsequently converted into dopamine (4) and further converstion of dopamine into 3,4-dihydroxyphenylacetaldehyde (5) results in the formation of norlaudanosoline (6) via a spontaneous Pictet-Spengler condensation of the two molecules. Evidence of these precursors was confirmed by 14C experiments where labeled compounds were administered to Aristolochia sipho and aristolochic acid was successfully extracted. Modification of norlaudanosoline is continued with a methylation of two alcohol groups to give orientaline (7). Orientaline undergoes a cyclization event to give the addition of the 5-membered ring into orientalinol (8), subsequently undergoing a methyl shift and aromatization event (9) to yield prestephanine (10). The final steps are the formation of stephanine (11) and the addition of a carboxylate to yield aristolochic acid (12). Comer et al. originally proposed a postulated pathway from norlaudanosoline to aristolochic acid in 1968 very similar to the described pathway but Sharma et al. confirmed the presence of the intermediate compounds via DL-[3-14C] tyrosine trapping experiments in Aristolochia bracteata in 1982. After the general backbone of aristolochic acid is synthesized, post-synthetic modifications are performed; for example, aromatization of one of the rings yields aristolochic acid I as seen at the top of the page.
Aristolochic acids are hypothesized to be causative agents in Balkan endemic nephropathy; and a related—possibly identical—condition known as "Chinese herbs nephropathy". Exposure to aristolochic acid is associated with a high incidence of uroepithelial tumorigenesis, and is linked to urothelial cancer.
In April 2001, the Food and Drug Administration issued a consumer health alert warning against consuming botanical products, sold as "traditional medicines" or as ingredients in dietary supplements, containing aristolochic acid. The agency warned that consumption of aristolochic acid-containing products was associated with "permanent kidney damage, sometimes resulting in kidney failure that has required kidney dialysis or kidney transplantation. In addition, some patients have developed certain types of cancers, most often occurring in the urinary tract."
In August 2013, two studies identified an aristolochic acid mutational signature in upper urinary tract cancer patients from Taiwan. The carcinogenic effect is the most potent found thus far, exceeding the amount of mutations in smoking-induced lung cancer and UV-exposed melanoma. Exposure to aristolochic acid may also cause certain types of liver cancer.
