2-(2,4-dihydroxyphenyl)naphthalene-1,4-dione, also known as juglone, is a chemical compound derived from the breakdown of the pigment lawsone. It is a polyphenolic compound with a molecular formula of C14H8O4 and a molecular weight of 240.21 g/mol. Juglone is a yellow crystalline solid that is soluble in organic solvents such as ethanol, acetone, and chloroform. It exhibits various biological activities, including anti-inflammatory, anti-cancer, and anti-bacterial properties. The compound is also known for its ability to inhibit the growth of certain plants, making it a potential herbicide. Juglone is found in the heartwood and bark of the black walnut tree (Juglans nigra) and is responsible for the tree's allelopathic effects on surrounding vegetation.

Check Digit Verification of cas no

The CAS Registry Mumber 51595-08-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,9 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 51595-08:
(7*5)+(6*1)+(5*5)+(4*9)+(3*5)+(2*0)+(1*8)=125
125 % 10 = 5
So 51595-08-5 is a valid CAS Registry Number.

The tyrosinase-inhibitory effects of 2-phenyl-1,4-naphthoquinone analogs: importance of the (E)-β-phenyl-α,β-unsaturated carbonyl scaffold of an endomethylene type

Ullah, Sultan,Akter, Jinia,Kim, Su J.,Yang, Jungho,Park, Yujin,Chun, Pusoon,Moon, Hyung R.

, p. 95 - 103 (2019)

In order to investigate the effect of the (E)-β-phenyl-α,β-unsaturated carbonyl scaffold of an endomethylene type on tyrosinase inhibition, 2-phenyl-1,4-naphthoquinone derivatives were synthesized by Michael addition of substituted benzenes to 1,4-naphtho

This work was aimed to the development of a set of new naphtoquinone derivatives that can act against glioma. The compounds were tested in order to find out their ability to inhibit the growth of glioma cells, and the results of these assays were correlated with electrochemical analysis and NMR-based reoxidation kinetic studies, suggesting that a redox mechanism underlies and may explain the observed biological behavior. In addition to a full description of the synthetic pathways, electrochemistry, NMR and single crystal X-ray diffraction data are provided.
