Naturally Occurring Hydroxy Napthoquinones and Their Iron Complexes as Modulators of Radiation Induced Lipid Peroxidation in Synaptosomes
The modulation of radiation induced lipid peroxidation in synaptosomes by iron (II) and iron (III) complexes of two naturally occurring and therapeutically relevant naphthoquinones viz. 5,hydroxy-1,4 naphthoquinone; juglone and 2,hydroxy-1,4 naphthoquinone; lawsone, have been studied. At lower concentrations the complexes enhance lipid peroxidation predominantly through redox cycling as observe...
متن کاملNovel naphthoquinone derivatives and evaluation of their trypanocidal and leishmanicidal activities.
Herein, we report the synthesis of 12 new naphthoquinone derivatives, 6 substituted 1,4-naphthoquinones and 6 heterocycle-fused naphthoquinones, as well as evaluation of their trypanocidal and leishmanicidal activities. Compounds 11a and 13a were active against the amastigote stage of T. cruzi and showed low cytotoxic effects. With respect to leishmanicidal assays, all compounds were inactive a...
متن کاملCytotoxic Naphthoquinones from Alkanna cappadocica
In a continuing program to discover new anticancer agents from plants, especially naphthoquinones from the Alkanna genus, Alkanna cappadocica was investigated. Bioassay-guided fractionation of a dichloromethane/methanol (1:1) extract of the roots led to the isolation of four new and four known naphthoquinones. The known compounds are 11-deoxyalkannin (1), , -dimethylacrylalkannin (2), 11-O-acet...
متن کاملBiflorin: an o-naphthoquinone of clinical significance.
Biflorin is an o-naphthoquinone with proven cytotoxic effects on tumor cells showing antimicrobial, antitumor and antimutagenic activities. Biflorin is an isolated compound taken from the roots of the plant Capraria biflora L. (Schrophulariaceae), indigenous of the West Indies and South America, which is located in temperate or tropical areas. This compound has shown to be strongly active again...
متن کاملAntibodies to 1,2-naphthoquinone.
SUMMARY We have prepared an antibody against 1,2-naphthoquinone. This was accomplished by conjugating the quinone to bovine gamma-globulin. The conjugation product showed a visible light absorption peak of 445 m/u. The globulin-quinone antigen was used to produce rabbit antibodies shown to be specific for 1,2-naphthoquinone. The antibodies could be demonstrated by tanned cell hemagglutination a...
