- Antiureolytic Activity of Substituted 2,5-Diaminobenzoquinones
-
A series of 2,5-bis(alkyl/arylamino)-1,4-benzoquinones (1–12) were investigated in vitro for their potential to inhibit the activity of jack bean urease. Compounds 1–6, 8, 9, 11 and 12 effectively inhibited the jack bean urease activity by 90.8 % when tes

Although quinones present a large array of biological activities, a few studies on the herbicidal potential of 2,5-bis(alkyl/arylamino)-1,4-benzoquinones have been reported to date. In this work, starting from benzoquinone, 13 2,5-bis(alkyl/arylamino)-1,4

- 2-(N-Alkyl-p-hydroxyanilino)-1,4-benzoquinones from p-Benzoquinones and Primary Aliphatic Amines. Studies on Quinones VI
-
In acetic (aqueous or chloroform) solution p-benzoquinones yield with primary aliphatic amines mainly 2-(N-alkyl-p-hydroxy-anilino)-1,4-benzoquinones besides the 2-alkylamino- and 2,5-bis(alkylamino)-quinones.The methyl-, ethyl-, n-propyl-, n-butylhomologues of p-benzoquinone and the isomer methylderivatives of toluquinone are described.Their structure were established by spectroscopic (UV/VIS, IR, NMR) methods and by synthesis of the methylderivative 3a from p-benzoquinone and p-hydroxy-N-methyl-aniline.The influence of other acids on the reaction was studied. - Keywords: N-Alkyl-p-hydroxyanilino-1,4-quinones; Quinones; Solvent influence
