BACKGROUND Aristolochia species used in the practice of traditional herbal medicine contains aristolochic acid (AA), an established human carcinogen contributing to urothelial carcinomas of the upper urinary tract. AA binds covalently to genomic DNA, forming aristolactam (AL)-DNA adducts. Here we investigated whether AA is also an etiologic factor in clear cell renal cell carcinoma (ccRCC). M...
Antiallergic activity of Aristolochia bracteolata was evaluated by using compound 48/80 induced anaphylaxis, dermatitis rhinitis and pruritus, as a preclinical model for acute phase of hypersensitivity reactions. The late phase hypersensitivity was evidenced by considering toluidine diisocyanate induced volume of bronchoalveolar fluid secretion and its inhibition. The possible antiallergic mech...
Balkan endemic nephropathy (BEN) is a devastating tubulointerstitial kidney disease affecting men and women living in rural areas of Bosnia–Herzegovina, Bulgaria, Croatia, Romania and Serbia [1]. The disease occurs exclusively in farming villages situated in valleys of the Danube River and its tributaries. Since its first description in 1956, the geographic distribution as well as other epidemi...
Aristolochic acid (AsA) is produced from Aristolochia fangchi, and has been used as a Chinese herbal medicine. AsA possesses various biological activities including antiplatelet, antifungal, and anti-inflammatory properties. The aim of this study was to examine the mechanisms of AsA in inhibiting platelet aggregation. AsA (75 - 150 microM) exhibited more-potent activity of inhibiting platelet a...
This review constitutes an overview of our investigations of aristolochic acid nephropathy, a chronic kidney disease associated with carcinomas of the upper urinary tract. Our studies began by confirming the hypothesis that chronic dietary poisoning by aristolochic acid was responsible for endemic (Balkan) nephropathy. A unique TP53 mutational signature in urothelial tumors and the presence of ...
BACKGROUND Aristolochic acid is a toxin found in plants of the genus Aristolochia, to which humans can be exposed either through certain Chinese herbal medicines or through inadvertent commingling with food crops. Our objective was to estimate cumulative exposures of aristolochic acid associated with increased risk of end-stage renal disease (ESRD), and to conduct a systematic review and meta-a...
Aristolochia maurorum L. of Jordanian origin has been investigated phytochemically, quantitatively, and biologically. Three atypical alkaloids, namely aristolochic acid I (1), aristolochic acid II (2) and aristolochic acid IIIa (3), have been isolated and identified. Of these known 1-phenanthrenecarboxylic acids, 2 and 3 are reported for the first time from this species. The identified compound...
