Home PI3K/Akt/mTOR Akt inhibitor - ERK inhibitor Usnic acid For research use only.

Usnic acid

Synonyms: Usniacin

Usnic acid (Usniacin) is a furandione found uniquely in lichen that is used widely in cosmetics, deodorants, toothpaste and medicinal creams as well as some herbal products. It exhibits antiviral, antiprotozoal, antiproliferative, anti-inflammatory and analgesic activity. Usnic acid inhibits breast tumor angiogenesis and growth by suppressing VEGFR2-mediated AKT and ERK1/2 signaling pathways.

Biological Activity

Description Usnic acid (Usniacin) is a furandione found uniquely in lichen that is used widely in cosmetics, deodorants, toothpaste and medicinal creams as well as some herbal products. It exhibits antiviral, antiprotozoal, antiproliferative, anti-inflammatory and analgesic activity. Usnic acid inhibits breast tumor angiogenesis and growth by suppressing VEGFR2-mediated AKT and ERK1/2 signaling pathways.
Targets
Akt [3] ERK [3]
In vitro
In vitro

Usnic acid inhibits cell growth involving G0/G1 phase cell cycle arrest and induces cell death via mitochondrial membrane depolarization and induction of apoptosis in human lung carcinoma cells. Usnic acid has shown activity againstmany cancer cells such as lung carcinoma cells, murine leukemia P388 and L1210 cells, colon carcinoma HT-29 and HCT-116 cells, breast adenocarcinoma MCF-7 cells, and cervix adenocarcinoma cells[1]. Usnic acid also selectively inhibits the viability of human breast cancer MCF-7 cells in a concentration- and time-dependent manner, provoking the generation of reactive oxygen species (ROS), which triggers the mitochondrial/caspase apoptotic pathway in MCF-7 cells[2].
Cell Research Cell lines A549 cells
Concentrations 25, 50, and 100 μM
Incubation Time 24 and 48 h
Method

Cells at a density of 1 × 105 are seeded per 60-mm culture plate and treated with either DMSO or indicated concentrations of usnic acid for 24 and 48 h. After each treatment time, cells are harvested by brief trypsinization and then gently mixed with trypan blue and counted using hemocytometer.
In Vivo
In vivo

In an MCF-7 xenograft model, Usnic acid significantly suppresses the growth of tumors by inducing apoptosis in the tumor cells without overt toxic side effects[2].
Animal Research Animal Models 6- to 8-week-old female BALB/c nu/nu mice (subcutaneously injected with MCF-7 cells)
Dosages 25, 50 or 100 mg/kg
Administration i.p.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
