ILIMAQUINONE

Description

Ilimaquinone is a natural sesquiterpene quinone that has antimicrobial, anti-HIV, anti-mitotic, and anti-inflammatory properties. In mammalian cells, 25 μM ilimaquinone reversibly induces vesiculation of Golgi membranes, blocking the secretory pathway. It inhibits the conversion of S-adenosylhomocysteine (SAH) to homocysteine by SAH hydrolase (IC₅₀ = 40 μM). Ilimaquinone also inhibits DNA polymerase β and dual specificity phosphatase Cdc25B (IC₅₀ = 45.2 and 92 μM, respectively) and, at 10 μM, activates gene expression through hypoxia-inducible factor-1.

The Uses of ILIMAQUINONE

Ilimaquinone is an ADP-ribosylation factor (ARF) and β-COP to the Golgi membrane inhibitor.

The Uses of ILIMAQUINONE

Biological probe for intracellular communications and vesicle-mediated transport.

Definition

ChEBI: A natural product found in Dactylospongia elegans.

General Description

A cell-permeable marine sponge metabolite with anti-microbial, anti-HIV, anti-inflammatory, and anti-mitotic properties. Induces a complete and reversible breakdown of Golgi membranes into smaller vesicular structures and causes depolymerization of microtubules. Inhibits cellular methylations through its interaction with S-adenosylhomocysteinase. Blocks the cytotoxicity of ricin and diphtheria toxin. Acts as an inhibitor of the RNase H activity of HIV-1.
