Objective(s): Lapachone is a natural naphthoquinone-derived compound found in Tabebuia avellanedae. It is well-known for its analgesic, anti-inflammatory, anti-microbial, diuretic, and anti-cancerous effects. However, the wound-healing effects of this compound are not known yet. The aim of this study was to investigate the wound healing activity of naphthoquinones (α-l...
The Paraguayan crude drug "tayï pytá" is used to treat cancer, wounds and inflammation. It consist of the bark and trunkwood of Tabebuia heptaphylla (Bignoniaceae). A phytochemical study of the crude drug gave, in addition to previously described naphthoquinones and the known lignans cycloolivil and secoisolariciresinol, three new lapachenol (lapachonone)-, two naphthofuran-, a chromone and a n...
AIM To study in vitro the molecular mechanism of apoptosis caused by beta-lapachone, a quinone obtained from the bark of the lapacho tree (Tabebuia avellanedae). MATERIALS AND METHODS The study was carried out on human bladder carcinoma T24 cell line. Determination of cell viability was done using trypan blue exclusion method, apoptosis quantitative estimation - by DAPI staining and agarose g...
The product of a tree (Tabebuia avellanedae) from South America, β-lapachone, is known to exhibit various pharmacological properties, the mechanisms of which are poorly understood. The aim of the present study was to further elucidate the possible mechanisms by which βlapachone exerts its anti-proliferative action in cultured human prostate cancer cells. We observed that the proliferation-inhib...
β-lapachone, a major component in an ethanol extract of Tabebuia avellanedae bark, is a promising potential therapeutic drug for various tumors, including lung cancer, the leading cause of cancer-related deaths worldwide. In the first part of this study, we found that apoptotic cell death induced in lung cancer cells by high concentrations of β-lapachone was mediated by increased activation of ...
BACKGROUND β-Lapachone is a quinone-containing compound found in red lapacho ( Tabebuia impetiginosa, syn. T avellanedae) trees. Lapacho has been used in traditional medicine by several South and Central American indigenous people to treat various types of cancer. The purpose of this study was to investigate the antimetastatic properties of β-lapachone and the underlying mechanisms using colon ...
The biological activities of the naphthoquinones lapachol and its cyclization product beta-lapachone, extracted from trees of the genus Tabebuia, have been intensively studied. Given continuity to the studies about heterocyclic derivatives obtained from the reaction of these naphtoquinones with amino-containing reagents, 22 derivatives of beta-lapachone, nor-beta-lapachone and lapachol were syn...
Lapachol whose isolation and study at the end of the century by Parternó, is one of the most brilliant chapters of Phytochemistry, especially in conjunction with the work of Max Siewert a communication on the wood of the Argentina Lapachol (Bignoniaceae) tree from Max Siewert, submitted along with Ricardo Napp in Exp. NAC. Philadelphia in 1876. The Lapachol has its origin in the Tabebuia avella...
The clinical utility of cisplatin is limited by nephrotoxicity. Oh et al. report that β-lapachone prevents this nephrotoxicity but not cisplatin's cytotoxicity for cancers. In addition to its potential clinical importance, the beneficial effect of β-lapachone on cisplatin acute kidney injury may illustrate fundamental processes that ordinarily link alterations in nutrient availability and intra...
