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.

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

Progesterone is required for maintenance of pregnancy, and peripheral concentrations of progesterone are affected by both production and inactivation. Hepatic cytochrome P450 (EC 1.14.14.1) and aldo-keto reductase (EC 1.1.1.145-151) enzymes play a pivotal role in the first step of steroid

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

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
