Aristolochic acid A

Aristolochic acid A (Aristolochic acid I; TR 1736) is the main component of plant extract Aristolochic acids, which are found in various herbal plants of genus Aristolochia and Asarum. Aristolochic acid A significantly reduces both activator protein 1 (AP-1) and NF-κB activities. Aristolochic acid A reduces BLCAP gene expression in human cell lines^[1]. In Vitro:Aristolochic acid A (150, 200 μM, 24 hours) inhibits the cell viabilities of kidney cells HEK293 and HK-2^[1].
Aristolochic acid A (100, 200 μM, 24 hours) causes a concentration-dependent decrease in bladder cancer-associated protein (BLCAP) mRNA levels in kidney cells (HEK 293 and HK-2) , and bladder cancer cell line (HT-1376)^[1].
Aristolochic acid A (100, 200 μM, 24 hours) weakens the BLCAP protein signals in a dose-dependent manner in both HEK293 and HT-1376 cells^[1]. In Vivo:Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

Aristolochic acid A can be used to induce nephrotoxicity models. Pharmacokinetic studies show that in male C57BL/6 mice, the concentration of Aristolochic acid A in the kidneys is higher than in the liver 30 minutes after intraperitoneal administration (10 mg/kg). The plasma concentration of Aristolochic acid A also peaks approximately 30 minutes after administration^[2].
