Disease relevance of Aristolochia

• Among fractions of Aristolochia cymbifera and Myroxylon balsamum, the hexane extracts showed the best results against Staphylococcus spp. and Pseudomonas aeruginosa [1].

High impact information on Aristolochia

• In this study, a rapid MEKC method using 40 mM sodium borate buffer containing 50 mM SDS as surfactant was developed for the analysis of aristolochic acid (AA) in Aristolochia plants [2].
• The mechanical properties of young stems of Aristolochia macrophylla Lam. and Aristolochia brasiliensis Mart. et Zucc. were studied during elongation growth and primary differentiation [3].
• Talaumidin, a tetrahydrofuran neolignan isolated from the root of Aristolochia arcuata, was shown to be an intriguing small molecule with neurotrophic activity in the primary culture of rat cortical neurons [4].
• The ethanol-water extract of Aristolochia taliscana Hook and Arn (Aristolochiaceae) yielded a compound which was identified as dehydrodiisoeugenol by means of elemental analysis, IR, UV, NMR, and mass spectra, and direct comparison with a synthetic sample [5].
• This is exemplified by aristolochic acids present in Aristolochia spp, undergoing reduction of the nitro group by hepatic cytochrome P450 (CYP1A1/2) or peroxidases in extrahepatic tissues to reactive cyclic nitrenium ion [6].

Associations of Aristolochia with chemical compounds

• 2-Deoxyribonolactones and four tetrahydroisoquinoline alkaloids were isolated from the acetone extract of the leaves of Aristolochia arcuata Mast., together with pinitol, sequoyitol, glycerol, fructose, sucrose, eupomatenoid-7, salsolinol, and 6,7-dihydroxy-1,1-dimethyl-1,2,3,4-tetrahydroisoquinoline [7].
• Tetrahydroisoquinoline alkaloids and 2-deoxyribonolactones from Aristolochia arcuata [7].
• This is the first report of isoquinolones and biphenyl ethers from this plant which may be representative units for the formation of bisbenzylisoquinoline alkaloids that are common metabolites of Aristolochia species [8].
• The interaction of aristololactam-beta-D-glucoside (ADG), a natural glucoside derivative of aristolochia group of alkaloids, with protonation-induced structures (H(L)-form) of poly(dG-dC).poly(dG-dC) and poly(dG-m(5)dC).poly(dG-m(5)dC) has been studied using different biophysical techniques [9].
• One new biphenyl ether, aristogin C (1), and two new porphyrins, aristophylls A (2) and B (3), as well as 11 known compounds, were isolated from the leaves of Aristolochia elegans [10].

Gene context of Aristolochia

• Aristolochic acid, an alkaloid (8-methoxy-6-nitrophenanthro(3,4-d)-1,3-dioxole-5-carboxylic acid) from the medicinal plant Aristolochia radix, interacts with these PLA2 enzymes [11].

Analytical, diagnostic and therapeutic context of Aristolochia

• The seeds of Aristolochia clematitis, obtained from plants growing in the endemic region, were extracted with ethanol and analyzed by high-performance liquid chromatography for their aristolochic acid content [12].
