General Description
Fusaric acid is a novel proton-affinitive derivatizing agent, having an ionization moiety and a hydrophobic moiety. It is commonly used for the derivatization of alcohols and phenols, by liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS).
Biological Activity
fusaric acid is a mycotoxin produced by several species of fusarium [1]. mycotoxins are biologically active secondary fungal metabolites found as contaminants of food- and feedstuff. mycotoxin is capable of causing disease and death in both humans and animals.fusaric acid is a potent inhibitor of dopamine β-hydroxylase. fusaric acid uncompetitively inhibited the activity of dopamine β-hydroxylase with an ic50 of 30 μm in an. fusaric acid lowered endogenous levels of norepinephrine and epinephrine in brain, spleen, heart, and adrenal glands. fusaric acid inhibited dopamine β-hydroxylase activity in adrenal medulla in vivo [2]. fusaric acid altered brain and pineal neurotransmitters. in the brain and pineal gland of rats, intraperitoneally (100 mg/kg) administration of fusaric acid increased the level of 5ht, 5-hydroxyindoleacetic acid (5hiaa), tyrosine, and dopamine [3].exposure to acute doses of fusaric acid caused vomiting and neurochemical changes in swine. fusaric acid might act synergistically with trichothecene mycotoxins to cause vomiting and feed refusal in pigs consuming trichothecene-contaminated feedstuffs [4].
Safety Profile
A poison by ingestion,
intraperitoneal, subcutaneous, and
intravenous routes. When heated to
decomposition it emits toxic fumes of NOx.
Purification Methods
Dissolve it in CHCl3, dry (Na2SO4), filter, evaporate and recrystallise the residue from 50 parts of pet ether (b 40-60o), CHCl3/pet ether or EtOAc, then sublime it in vacuo. The amide crystallises from MeOH with m 128.2-129.0o. The copper salt forms bluish violet crystals from H2O and has m 258-259o.

Check Digit Verification of cas no
The CAS Registry Mumber 536-69-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 536-69:
(5*5)+(4*3)+(3*6)+(2*6)+(1*9)=76
76 % 10 = 6
So 536-69-6 is a valid CAS Registry Number.

Concise Total Synthesis and Antifungal Activities of Fusaric Acid, a Natural Product
Huang, Bin Bin,Liu, Ya Yi,Zhu, Peng Fei,Jiang, Yi Cheng,Ouyang, Ming-An
, (2020/09/04)
The total synthesis of a natural product alkaloid fusaric acid (FA), which exhibits herbicide, fungicide, insecticide and even diverse notable pharmacological activities, was accomplished in four steps using commercially available materials. The synthesis, based on a unified and flexible strategy using 6-bromonicotinaldehyde as a common intermediate, is concise, convergent, practical and can be carried out on a two-gram scale. This approach could be readily applicable to the synthesis of its analogues. In addition, FA had a wide range of inhibitory activities against 14 plant pathogenic fungi in this study, which demonstrated that as a leading compound, and it has great potential to be further developed as an agricultural fungicide.

Taking advantage of microwave-assisted synthesis, efficient and expedite procedures for preparation of a library of fusaric acid and 39 analogues are reported. The fusaric acid analogues were tested in cell-based screening assays for inhibition of the las and rhl quorum sensing system in Pseudomonas aeruginosa and the lux quorum sensing system in Vibrio fischeri. Eight of the 40 compounds in the library including fusaric acid inhibited lux quorum sensing and one compound inhibited activity of the las quorum sensing system. To our delight, none of the compounds showed growth inhibitory effects in the tested concentration ranges.
Synthesis of substituted pyridines via regiocontrolled [4 + 2] cycloadditions of oximinosulfonates
Renslo, Adam R.,Danheiser, Rick L.
, p. 7840 - 7850 (2007/10/03)
Diels-Alder cycloadditions of oximinosulfonate 8 with a variety of 1, 3-dienes proceed with regiochemistry opposite to that observed with conventional imino dienophiles, providing expeditious synthetic routes to substituted pyridines, tetrahydropyridines, and pyrrolines. The oximinosulfonate 8 is prepared in one convenient synthetic operation from Meldrum's acid and reacts with conjugated dienes at -78 C in the presence of 2 equiv of dimethylaluminum chloride to afford [4 + 2] cycloadducts in good to excellent yield. Exposure of these cycloadducts to the action of NaOMe and JV-chlorosuccinimide in methanol-THF at room temperature then produces substituted pyridines. The utility of this new two-step annulation protocol is demonstrated in total syntheses of the pyridine alkaloids fusaric acid and (S)-(+)-fusarinolic acid. Heating the [4 + 2] cycloadducts derived from 8 in a mixture of acetonitrile and pH 7 phosphate buffer induces an unusual Stieglitztype rearrangement leading to the formation of interesting spirobicyclic pyrrolines.
