Description

Biochem/physiol Actions

Prototype of the 4-hydroxycoumarin class of anticoagulants, which act as vitamin K antagonists, preventing formation of prothrombin. There are many reports that dicumarol also inhibits NADPH:quinone oxidoreductase (NQO(1)). In one, it inhibited NQO(1) in a pancreatic cancer cell line, causing increased formation of superoxide and inhibiting cell growth.

Synthesis and structure-activity relationships of lapacho analogues. 1. Suppression of human keratinocyte hyperproliferation by 2-substituted naphtho[2,3-b]furan-4,9-diones, activation by enzymatic one- and two-electron reduction, and intracellular generation of superoxide.

Alexandra Reichstein et al.

Journal of medicinal chemistry, 55(16), 7273-7284 (2012-08-01)

A series of linearly anellated lapacho quinone analogues substituted at the 2-position of the tricyclic naphtho[2,3-b]furan-4,9-dione system were synthesized and evaluated for their ability to suppress keratinocyte hyperproliferation using HaCaT cells as the primary test system. While very good in

Inhibitors of NQO1: identification of compounds more potent than dicoumarol without associated off-target effects.

Katherine Ann Scott et al.

Biochemical pharmacology, 81(3), 355-363 (2010-10-26)

The enzyme NAD(P)H quinone oxidoreductase (NQO1) can function both as a detoxifying enzyme as well as chaperone protein. The latter property has been extensively characterized by the use of dicoumarol which inhibits the chaperone properties of NQO1 in cells. However

Pharmacological inhibitors of NAD(P)H quinone oxidoreductase, NQO1: structure/activity relationships and functional activity in tumour cells.

Karen Ann Nolan et al.

Biochemical pharmacology, 80(7), 977-981 (2010-07-06)

NAD(P)H quinone oxidoreductase (NQO1) has multiple functions in the cell including an ability to act as a detoxifying enzyme and as a protein chaperone. The latter property is particularly important in oncology as one of the client proteins of NQO1
