In Vitro

Withaferin A has antiinflammatory activity, and potently inhibits NF-kB activation by preventing the TNF-induced activation of Ik-B kinase beta via a thioalkylation-sensitive redox mechanism^[1].
Withaferin A also has anticancer activity. Withaferin A targets the IF protein vimentin, causes aggregation of vimentin filaments in bovine aortic endothelial cells (BAECs) at 3 μM, and induces vimentin fragmentation in endothelial cells at 10 μM^[2].
Withaferin A (0.5, 1.5 μM) alone or incombination with cisplatin (CIS) dose-dependently reduces tumorigenic potential of ALDH1 positive cancer stem cells (CSCs)^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Withaferin A (2 mg/kg, i.p.) shows potent angiogenesis inhibitory activity via vimentin in mice^[2]. Withaferin A (2 mg/kg) combined with cisplatin (CIS) regulates the expression of ALDH1 marker, and downregulates the expression of securin in tumors collected from mice^[3].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 0.83 mg/mL (1.76 mM); Clear solution

This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 0.83 mg/mL (1.76 mM); Clear solution

This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 0.83 mg/mL (1.76 mM); Clear solution

This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay^[3]

Ovarian epithelial cancer cell line A2780 is maintained in RPMI1640 medium supplemented with insulin (5 μg/mL), penicillin/streptomycin (100 IU/mL and 100 μg/mL respectively) and 10% fetal bovine serum (FBS) from Hyclone. Withaferin A, cisplatin (CIS) and other reagents are prepared in DMSO. Cisplatin is prepared fresh each time^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration^[2]

Mice^[2]
Vimentin homozygous-deficient mice (Vim^−/−) and mice that are vimentin-heterozygous deficient (Vim^+/−) in the 129/Svev background are used in the assay. In brief, mice between 4 and 6 wk of age are anesthetized by intraperiteoneal (i.p.) injection of ketamine and xylazine. Corneas are topically anesthetized by application of proparacain eye drop, and 1 μL drop of dilute 0.15 M sodium hydroxide is applied for 1 min. The cornea is immediately washed extensively in saline solution, and corneal and limbal epithelium gently removed by scraping. The cornea is topically treated with atropine eye drop and covered with tobramycin and erythromycin antibiotic eye ointment. Withaferin A or 12-D WS (2 mg/kg solubilized in DMSO) or vehicle (DMSO) is injected i.p. in respective drug or control groups of mice after their recovery from corneal injury, and subsequently every day thereafter for a period of 10 days. Mice are humanely killed and eyes enucleated. The anterior segment half of eyes are dissected and corneal buttons are prepared. Corneal tissues are fixed in 100% acetone for 20 min, washed in PBS for 1 hr, and blocked for 18 hr in 1% BSA-PBS at 4°C. Cornea whole-mount staining is performed by incubating tissues in FITC-conjugated rat anti-mouse CD31 antibody (1:333 dilution in 1% BSA-PBS) for 12 hr, washed away for 24 hr at 4°C in 1% BSA-PBS, and affixed to glass slides with a coverslip. Fluorescent staining is visualized on microscope, and quantified by importing digital images to NIH ImageJ^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
