, p. 6052 - 6057 (2010)
Several members of the phenylamino-1,4-naphthoquinone series were prepared in order to investigate structure-activity relationships (SAR) and to explore the antitumor effects associated with this scaffold. The cytotoxic effects of the aminoquinones (ECsu
Substituted 1,4-Naphthoquinones vs. the Ascitic Sarcoma 180 of Mice
Hodnett, Ernest M.,Wongwiechintana, Chinda,Dunn, William J.,Marrs, Pam
, p. 570 - 574 (1983)
Twelve 1,4-naphthoquinones have been tested against the ascitic form of sarcoma 180 in Swiss mice.Statistical analysis shows that the most important molecular parameter determining their effectiveness in prolonging the life of mice bearing this tumor is their redox potentials.Although the toxicities of the compounds are also related to the redox potentials in the same way, the therapeutic indexes can be increased by adding substituents of greater lipophilicity.The naphthoquinones differ greatly in antitumor activities and may inhibit the growth of malignant cells by different mechanisms

, p. 259 - 268 (2019)
Five new chemo-receptors, based on arylamino-naphthoquinone, possessing electron donating and electron withdrawing substituents have been prepared by single step green method. These receptors are found to be highly selective and sensitive towards cyanide
Synthesis, antimicrobial properties, and inhibition of catalase activity of 1,4-naphtho-and benzoquinone derivatives containing N-, S-, O-substituted

, p. 589 - 600 (2019)
1,4-Naphthoquinones are an important class of compounds present in a number of natural products. In this study, a new series of 1,4-naphthoquinone derivatives were synthesized. All the synthesized compounds were tested for in vitro antimicrobial activity.
Spectroscopic and theoretical studies on the nucleophilic substitution of 2,3-dichloronaphthoquinone with para-substituted anilines in solid state via initial charge transfer complexation
Satheshkumar, Angupillai,Elango, Kuppanagounder P.
, p. 378 - 383,6 (2012)
Various spectroscopy techniques (UV-Vis, DRS, FT-IR, 1H NMR, LC-MS) and theoretical computations have been employed to investigate the mechanism of the nucleophilic substitution reaction of 2,3- dichloronaphthoquinone (DCNQ) with para-substitut
Synthesis of novel 2-(fluoroanilino)-3-(2,4-dinitroanilino) derivatives of 1,4-naphthoquinone

, p. 5248 - 5251 (2015)
Several novel 2-(fluoroanilino)-3-(2,4-dinitroanilino) derivatives of 1,4-naphthoquinone have been synthesized in good to excellent yields. First, 2-chloro-3-(2,4-dinitroanilino)-1,4-naphthoquinone was prepared in two steps beginning with the reaction of
Thermolysis of 2-azido-3-(R-anilino)-1,4-naphthoquinones. Nitrene insertion versus hydrogen abstraction

2-chloro-3-(R-anilino)-1,4-naphthoquinones react with sodium azide upon refluxing in DMF. The thermochemistry of 2-azido-3-(R-anilino)-1,4-naphthoquinone is strongly modified by the substituent on aniline. Having an strong electron-donor like O-R results
Discovery of Novel 2-Aniline-1,4-naphthoquinones as Potential New Drug Treatment for Leber's Hereditary Optic Neuropathy (LHON)
Varricchio, Carmine,Beirne, Kathy,Aeschlimann, Pascale,Heard, Charles,Rozanowska, Malgorzata,Votruba, Marcela,Brancale, Andrea

Leber's hereditary optic neuropathy (LHON) is a rare genetic mitochondrial disease and the primary cause of chronic visual impairment for at least 1 in 10 ?000 individuals in the U.K. Treatment options remain limited, with only a few drug candidates and therapeutic approaches, either approved or in development. Recently, idebenone has been investigated as drug therapy in the treatment of LHON, although evidence for the efficacy of idebenone is limited in the literature. NAD(P)H:quinone oxidoreductase 1 (NQO1) and mitochondrial complex III were identified as the major enzymes involved in idebenone activity. Based on this mode of action, computer-aided techniques and structure-activity relationship (SAR) optimization studies led to the discovery of a series naphthoquinone-related small molecules, with comparable adenosine 5′-triphosphate (ATP) rescue activity to idebenone. Among these, three compounds showed activity in the nanomolar range and one, 2-((4-fluoro-3-(trifluoromethyl)phenyl)amino)-3-(methylthio)naphthalene-1,3-dione (1), demonstrated significantly higher potency ex vivo, and significantly lower cytotoxicity, than idebenone.
