Product Description
AN0128 is a boron-containing antibacterial and anti~inflammatory agent. AN0128 The minimum inhibitory concentration (MIC) values for S. aureus, S. epidermidis, P. acnes, and B. subtilis are 1, 0.5, 0.3, and 1 μg/mL. AN0128 may be utilized in the research/study of periodontal and dermatological diseases.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
AN0128 (compound 2g; 10 μM; 24-48 hours) has a potent inhibitory effect on human peripheral blood mononuclear cells (PBMCs) when it comes to the production of proinflammatory cytokines (TNF-α, IL-1β), but not on the release of IFN-γ or IL-4 without inhibition [1].
ln Vivo
AN0128 (1%, 5%; administered topically daily for 7 days) significantly inhibits the production of inflammatory infiltrates and minimizes bone loss [2].
Animal Protocol
Animal/Disease Models: Experimental periodontitis in 12weeks old male SD (SD (Sprague-Dawley)) rats (weight 275 to 300 g each) [2]
Doses: 1% AN0128 in 40% Transcutol P, 40% PBS and 20% ethanol vehicle Daily topical application for 7 days.
Experimental Results: Similar to ketorolac, bone area and bone volume increased by 50% and 35% respectively, and bone loss and inflammation were diminished by 38% and 42% respectively.

Animal/Disease Models: Experimental periodontitis in 12weeks old male SD (SD (Sprague-Dawley)) rats (weight 275 to 300 g each) [2]
Doses: Use with Total Toothpaste 5%
Route of Administration: Apply daily via cotton-tipped applicator . Results for 7 days: better than Total toothpaste, increasing bone mass by 33% and reducing bone loss by 47%.

Additional Infomation
AN0128 is a novel compound that contains a boron atom within a borinic acid complex. AN0128 has broad spectrum activity against a wide variety of Gram positive bacteria, including many that are known skin colonizers. Of particular importance is P. acnes and its causal role in acne vulgaris. The rise in antibiotic resistance of P. acnes to standard antibiotics necessitates the development of new treatment agents. AN0128 is a good candidate for a topical antibiotic and is currently being developed by Anacor as a novel therapeutic for acne and atopic dermatitis.
Drug Indication
Investigated for use/treatment in acne, atopic dermatitis, pediatric indications, and psoriasis and psoriatic disorders.
Mechanism of Action
AN0128 inhibits the release of pro-inflammatory cytokines, including TNF- alpha, without affecting the normal immune response.

Solubility Data
Solubility (In Vitro)
DMSO : ~125 mg/mL (~312.45 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.20 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.08 mg/mL (5.20 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)

5 mM 0.4999 mL 2.4996 mL 4.9993 mL
10 mM 0.2500 mL 1.2498 mL 2.4996 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
