(+)-Usniacin Chemical Properties,Usage,Production
Preparation
Weigh 5.0 g of chopped Usnea longiflora into a 500 mL flask, and extract with 75 mL of ethyl acetate for 2 times, 4 h each time, and combine the extracts. Suction filtration, concentrated to 1/6~1/8 of the original volume, naturally cooled, crystallized, filtered off the mother liquor, and dried at 80°C to obtain the crude usnic acid. 30 times the amount of benzene-ethanol (volume ratio 1:1) mixed solvent was added to the crude product, refluxed for 2 h, filtered while hot, the filtrate was concentrated to 1/5 of the original volume, and crystals were precipitated by cooling. Dry at 80 ℃, recrystallize twice with ethyl acetate, and the obtained relatively pure pale yellow needle crystal is the fine usnic acid.
Uses
Usnic acid is used as fragrance; preservative in deodorants; in anti ac ne formulations; antibiotic for topical application.
Uses
Usnic Acid acts as an antibacterial and antifungal agent, and are often seen used in cosmetics and facial application chemicals.
Uses
(+)-Usnic acid has been used to study the following:
- The mechanism of its antimicrobial activity in bacterial cells.
- Its ability as an antibiofilm agent against Group A Streptococci (GAS).
- Its ability as a potent anti-virulent compound against Candida albicans.
- The mechanism of its toxic effect on hepatocytes.
- Its ability to inhibit the motility of human lung cancer cells.
Definition
ChEBI: (-)-usnic acid is the (-)-enantiomer of usnic acid. It has a role as an EC 1.13.11.27 (4-hydroxyphenylpyruvate dioxygenase) inhibitor. It is a conjugate acid of a (-)-usnic acid(2-). It is an enantiomer of a (+)-usnic acid.
General Description
(+)-Usniacin is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG.
Biological Activity
mic: 0.05 μg/62.5 μl to 3.1 μg/62.5 μlmicroorganisms can colonize a wide variety of medical devices, putting patients at risk for systemic and local infectious complications, including local-site infections, endocarditis, and catheter-related bloodstream infections. (+)-usniacin is a secondary lichen metabolite that possesses antimicrobial activity against various planktonic gram-positive bacteria.
Contact allergens
Usnic acid is a component of lichens, also used as a topical antibiotic. Allergic contact dermatitis from lichens occurs mainly occupationally in forestry and horticultural workers, and in lichen pickers.
in vitro
(+)-usniacin showed antimicrobial activity against the same microorganisms as that of acetone extract. among the three analogues it was the most active one having quite low mic values. furthermore, (+)-usniacin did not show any activity against a. hydrophila and b. cereus whereas (d)-usnic acid did. on the other hand, (+)-usniacin was active against y. enterocolitica whereas (d)-usnic acid was not active [1].
Purification Methods
This very weak acid is the natural form which is recrystallised from Me2CO, MeOH or *C6H6. At 25o it is soluble in H2O (<0.01%), Me2CO (0.77%), EtOAc (0.88%), MeOCH2CH2OH (0.22%) and furfural (7.32%).
