Used in Environmental Studies:
3,7,9-TRIHYDROXY-1-METHYL-6H-DIBENZO[B,D]PYRAN-6-ONE is used in the study of indoor air, soil, and plants, as it is a mycotoxin present in these environments. This helps in understanding the impact of Alternariol on human health and the environment.
Used in Pharmaceutical Research:
3,7,9-TRIHYDROXY-1-METHYL-6H-DIBENZO[B,D]PYRAN-6-ONE is used as a research compound in the development of new drugs and therapies, particularly in the field of cancer treatment, due to its cytotoxic properties.
Used in Agriculture:
3,7,9-TRIHYDROXY-1-METHYL-6H-DIBENZO[B,D]PYRAN-6-ONE is used in the study of Alternaria species, which are common mycoflora infecting small grain cereals. This helps in developing strategies to control the growth of these molds and reduce the contamination of cereals with Alternariol.
Biochem/physiol Actions
Alternaria mycotoxins are generally associated with undried food grains post-harvest. The disease caused by Alternaria mycotoxin results in a discolored halo in fruits and spotting in leaves. Alternariol (AOH) is cytotoxic and fetotoxic to microbes and mammalian cells. AOH displays inhibitory effect on cell proliferation and has estrogenic functionality.

Check Digit Verification of cas no
The CAS Registry Mumber 641-38-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 641-38:
(5*6)+(4*4)+(3*1)+(2*3)+(1*8)=63
63 % 10 = 3
So 641-38-3 is a valid CAS Registry Number.

Concise Syntheses of Alternariol, Alternariol-9-monomethyl Ether and Their D 3-Isotopologues
Gebauer, Julian,Koch, Matthias,Sebald, Michael A.
, (2022/01/27)
Alternariol (AOH) and alternariol-9-monomethyl ether (AME) are two secondary metabolites of Alternaria fungi which can be found in various foodstuffs like tomatoes, nuts, and grains. Due to their toxicity and potential mutagenic activity the need for the development of high-throughput methods for the supervision of AOH and AME levels is of increasing interest. As the availability of both native and labeled AOH and AME analytical standards is very limited, we herein present a novel and concise approach towards their synthesis by employing a ruthenium- catalyzed ortho-arylation as the key step. Finally, we demonstrate their suitability as internal standards in stable-isotope dilution assay (SIDA)-HPLC-MS/MS analysis, a technique commonly used for the quantification of natural products in food and feed.
Synthesis of alternariol through an intramolecular biaryl coupling reaction using palladium reagent
Abe, Hitoshi,Fukumoto, Tomoko,Takeuchi, Yasuo,Harayamac, Takashi
, p. 265 - 271 (2008/09/17)
The facile synthesis of altemariol was accomplished through an intramolecular biaryl coupling reaction of the phenyl benzoate derivative, which was prepared by the simple esterification of the corresponding phenol and benzoic acid using a palladium reagen

, p. 2233 - 2237 (2007/10/02)
A novel method for the preparation of 6-aryl-2,4-dimethoxybenzoic acids involving the Alder-Rickert reaction of 1,5-dimethoxycyclohexa-1,4-dienes and arylpropiolic esters is described.This strategy has been extended to the synthesis of the mould metabolite alternariol and methyl trimethylaltenusin.
