Description: Penciclovir sodium (BRL39123) is a guanosine analog used as an antiviral drug for the treatment of various herpesvirus infections. It has activity against HSV types 1 and 2 with IC50 of 0.04-1.8 μg/mL and 0.06-4.4 μg/mL, respectively. As a nucleoside analogue, Penciclovir exhibits low toxicity and good selectivity. Penciclovir is absorbed poorly when given orally, thus it is used as a topical treatment, and is the active ingredient in the cold sore medications such as Denavir, Vectavir and Fenivir.
| ln Vitro |
Penciclovir sodium (0-100 µg/ml) exhibits anti-herpesvirus action, with EC50s for HSV-1 (HFEM), HSV-2 (MS), VZV (Ellen), CMV (AD-169), BHV-1 (Oxford 1964), BHV-2 (New York 1), EHV-1 (Quai Hals), FHV-1 (B927), and SVV, respectively, 0.5, 0.8, 2.4, 52, 100, 1.2, 1.6, 0.9, >100 µg/ml[1]. To uninfected human cells, penciclovir sodium (0–100 µg/ml) exhibits no toxicity[1].

| Additional Infomation |
Penciclovir Sodium is the sodium salt form of penciclovir, a synthetic acyclic guanine derivative with antiviral activity, mainly used to treat infections from herpes simplex virus (HSV) types 1 and 2. In HSV infected cells, penciclovir is phosphorylated by viral thymidine kinase and subsequently converted by cellular kinases into the active metabolite, penciclovir triphosphate, which competitively inhibits viral HSV polymerase by blocking deoxyguanosine triphosphate substrate binding. As a result, herpes viral DNA synthesis and replication are selectively inhibited.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 3.6332 mL | 18.1660 mL | 36.3319 mL | |
| 5 mM | 0.7266 mL | 3.6332 mL | 7.2664 mL | |
| 10 mM | 0.3633 mL | 1.8166 mL | 3.6332 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.
