Descrizione generale

Tenuazonic acid is a biologically active compound and its mode of action involves the inhibition of protein biosynthesis.
Tenuazonic acid is a mycotoxin, which belongs to the class of tetramic acids, the largest family of natural products. It is generally isolated from phytopathogenic fungal species like Alternaria alternata, A. longipes and A. tenuissima.

Applicazioni

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Tenuazonic acid may be used as an analytical reference standard for the quantification of the analyte in the following:
  • Cornflakes using high-performance liquid chromatography (HPLC) technique.
  • Human urine samples using isotope dilution assay method and liquid chromatography coupled to a hybrid triple quadrupole/linear ion trap mass spectrometer.
  • Cereals using high-performance liquid chromatography–electrospray ionization ion-trap multistage mass spectrometry (HPLC- ESI ion-trap (IT) MS2). ESI Fourier transform-ion cyclotron resonance tandem mass spectrometry (FTICR-MS2) technique is used for product characterization, post derivatization with 2,4-dinitrophenylhydrazine.

The group of the small-spored Alternaria species is particularly relevant in foods due to its high frequency and wide distribution in different crops. These species are responsible for the accumulation of mycotoxins and bioactive secondary metabolites in food. The taxonomy

The synthesis of 3-acyltetramic acids, the substructure of bioactive natural products, via O-acylation of tetramic acids with carboxylic acids followed by acyl migration, has been investigated. This acylation sequence is mediated by N,N'-dicyclohexylcarbodiimide (DCC) and 4-dimethylaminopyridine (DMAP) and is very

3-Acetyl-5-isopropyltetramic acid (3-AIPTA), a derivate of tetramic acid, is responsible for brown leaf-spot disease in many plants and often kills seedlings of both mono- and dicotyledonous plants. To further elucidate the mode of action of 3-AIPTA, during 3-AIPTA-induced cell necrosis

A stable isotope dilution assay (SIDA) for the Alternaria mycotoxin tenuazonic acid was developed. Therefore, [(13)C(6),(15)N]-tenuazonic acid was synthesized from [(13)C(6),(15)N]-isoleucine by Dieckmann intramolecular cyclization after acetoacetylation with diketene. The synthesized [(13)C(6),(15)N]-tenuazonic acid was used as the internal standard for

Molecularly imprinted porous polymer microspheres selective to Alternaria mycotoxins, alternariol (AOH) and alternariol monomethyl ether (AME), were synthesized and applied to the extraction of both mycotoxins in food samples. The polymer was prepared using 4-vinylpiridine (VIPY) and methacrylamide (MAM) as
