60924-75-6 Usage

Definition

ChEBI: A member of the class of asterriquinones that is asterriquinone in which the hydrogens of both of the hydroxy groups have replaced by methyl groups.

Check Digit Verification of cas no

The CAS Registry Mumber 60924-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,9,2 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 60924-75:
(7*6)+(6*0)+(5*9)+(4*2)+(3*4)+(2*7)+(1*5)=126
126 % 10 = 6
So 60924-75-6 is a valid CAS Registry Number.

AstPT catalyses both reverse N1- and regular C2 prenylation of a methylated bisindolyl benzoquinone

Tarcz, Sylwia,Ludwig, Lena,Li, Shu-Ming

, p. 108 - 116 (2014/01/06)

Prenylated bisindolyl benzoquinones exhibit interesting biological activities, such as antidiabetic or anti-HIV activities. A number of these compounds, including asterriquinones, have been isolated from Aspergillus terreus. In this study, we identified two putative genes by genome mining, ATEG-09980 and ATEG-00702, which share high sequence similarity with the known bisindolyl benzoquinone prenyltransferase TdiB from Aspergillus nidulans. The coding sequences were cloned and overexpressed in E. coli. The overproduced recombinant proteins were purified to near homogeneity and used for enzyme assays with asterriquinone D in the presence of dimethylallyl diphosphate. HPLC analysis showed that product formation was only detected in enzyme assays with EAU29429 encoded by ATEG-09980, not in those with EAU39348 encoded by ATEG-00702. Product isolation and structure elucidation by NMR and MS analyses led to identification of N1-reversely and C2-regularly monoprenylated derivatives, as well as N1′,N1′′reversely, N1′-reversely, C2′′-regularly diprenylated derivatives. This proved that EAU29429 functions as an asterriquinone prenyltransferase (AstPT) and indicated the involvement of EAU29429 rather than EAU39348 in the biosynthesis of methylated asterriquinones. Furthermore, incubation of monoprenylated enzyme products with AstPT resulted in the formation of the diprenylated derivatives. Copyright

Partial deacetylation of asterriquinone diacetate by aqueous sodium bicarbonate in pyridine

Kaji,Kimura,Iwata,Kiriyama

, p. 1818 - 1820 (2007/10/03)

Asterriquinone (ARQ); 2,5 -bis[1-(1,1-dimethyl-2-propenyl)-1H-indol-3- yl]-3,6-dihydroxy-2,5-cyclohexadiene-1,4-dione and ARQ monoacetate are metabolites from mycelium of Aspergillus terreux IFO 6123. ARQ diacetate was convened into ARQ monoacetate by treatment with 5% aq. NaHCO3 in pyridine at 80°C for 5 min, and the yield was 93.4%. Similarly, by treatment with 5% aq. NaHCO3 in acetone at room temperature, 2,5-diacetoxy-p-xyloquinone and 2,5- diacetoxy-p-benzoquinone were convened into 2-acetoxy-5-hydroxy-p-xyloquinone (yield, 85.8%) and 2-acetoxy-5-hydroxy-p-benzoquinone (yield, 66.7%), respectively.
