Application

β-Lapachone has been used:
  • as an anticancer compound in catalase-inhibitable luminol/hydrogen peroxide (HRP)-dependent chemiluminometric assay in Lewis lung carcinoma (LLC) cells and isolated mitochondria
  • as a naphthoquinone to study its effects on the growth and differentiation of mice granulocyte and macrophage progenitor cells
  • as a substrate to study the enzyme activity of human recombinant NAD(P)H dehydrogenase 1 (NQO1) protein

Actions biochimiques/physiologiques

β-Lapachone acts as a DNA topoisomerase type I inhibitor. It exhibits anti-fungal, anti-bacterial, trypanocidal, and antiviral properties. β-Lapachone also inhibits nitric oxide (NO) and inducible NO synthase (iNOS) in alveolar macrophages.
β-Lapachone is a naturally occurring quinone obtained from the bark of the lapacho tree (Tabebuia avellanedae) with cancer chemopreventive properties. Induces apoptosis in HL-60 and human prostate cancer cells.

Quinones represent a large and diverse class of antitumor drugs and many quinones are approved for clinical use or are currently undergoing evaluation in clinical trials. For many quinones reduction to the hydroquinone has been shown to play a key

beta-Lapachone and certain of its derivatives directly bind and inhibit topoisomerase I (Topo I) DNA unwinding activity and form DNA-Topo I complexes, which are not resolvable by SDS-K+ assays. We show that beta-lapachone can induce apoptosis in certain cells, such

β-Lapachone (β-lap) is a promising antitumoral agent. DNA base oxidation and alkylation are among the expected damages by β-lap. Herein, we have explored the role that the homologous recombination pathway (HR), a critical DNA repair process in Saccharomyces cerevisiae, has

Agents, such as β-lapachone, that target the redox enzyme, NAD(P)H:quinone oxidoreductase 1 (NQO1), to induce programmed necrosis in solid tumors have shown great promise, but more potent tumor-selective compounds are needed. Here, we report that deoxynyboquinone kills a wide spectrum

The aim of this study was to encapsulate lapachone (β-lap) or inclusion complex (β-lap:HPβ-CD) in liposomes and to evaluate their physicochemical characteristics. In addition, the investigation of the main aspects of the interaction between β-lap and 2-hydroxypropyl-β-cyclodextrin (HPβ-CD), using both
