Zaragozic acid A Structural

What is Zaragozic acid A?

Chemical properties

White to light tan solid. Soluble in ethanol (10 mg/ml), methanol, DMF, DMSO (10 mg/ml), and water (moderate).

The Uses of Zaragozic acid A

Zaragozic acid A is the major metabolite of a class of unusual bicyclic tricarboxylic acids, produced by a number of fungi in the genera Curvularia, Exserohilum, Setosphaeria and others, discovered at Merck and Glaxo in the early 1990s. In nature, zaragozic acid A acts as broad spectrum antifungal but its mode of action as an inhibitor of squalene synthase, involved in sterol biosynthesis, lead to investigation as a cholesterol lowering agent. Zaragozic acid A prepared by BioAustralis is presented as the free acid rather than the tri-sodium salt to avoid stability problems associated with hydrolysis of the salt.

What are the applications of Application

Zaragozic Acid A is a squalene synthetase inhibitor and fungal metabolite containing a novel 4,6,7-trihydroxy-2,8-dioxobicyclo[3.2.1]octane-3,4,5-tricarboxylic acid core.

Definition

ChEBI: Zaragozic acid A is a polyketide isolated from fungi that is a potent inhibitor of fungal and mammalian squalene synthase. It has a role as an EC 2.5.1.21 (squalene synthase) inhibitor and a fungal metabolite. It is a tricarboxylic acid, an acetate ester, a cyclic ketal, an oxabicycloalkane, a tertiary alcohol and a polyketide.

What are the applications of Application

Zaragozic Acid A is a squalene synthetase inhibitor. it targeted squalene synthase and lowered the cholesterol levels in vivo of marmosets.

Biological Activity

Zaragozic acid A is an inhibitor of acute liver cholsterol synthesis (50% inhibition dose 200 μg/ kg) with Ki value of 78pM. It inhibited cholesterol synthesis in Hep G2 cells.

in vitro

zaragozic acid a, as well as it two analogs zaragozic acid b and c were discovered from an unidentified sterile fungal culture, spororniella intermedia, and leptodontium elatius, respectively. zaragozic acid a, b and c were reported to be three potent competitive inhibitors of rat liver squalene synthase with ki values of 78 pm, 29 pm, and 45 pm, respectively. in addition, zaragozic acid a, b and c could also inhibite cholesterol synthesis in hep g2 cells [1].

in vivo

in the mouse model, zaragozic acid a was found to be an inhibitor of acute hepatic cholesterol synthesis (50% inhibitory dose of 200 μg/kg). the in-vivo inhibition of squalene synthase was accompanied by an accumulation of label from [3hjmevalonate into farnesyl diphosphate, farnesol, as well as organic acids. in summary, these data showed the zaragozic acids were a new class of therapeutic agents with potential for the hypercholesterolemia treatment [1].
