Purity: ≥98%
Dapivirine (also known as TMC120) is a potent non-nucleoside inhibitor for HIV reverse transcriptase with IC50 of 24 nM, it inhibits a broad panel of HIV-1 isolates from different classes, inclucing a wide range of NNRTI-resistant isolates. Dapivirine prevents HIV-induced syncytium formation in the nanomolar range and shows a low cytostatic activity. Dapivirine apparently blocks HIV-1 infection in the primary cultures at a 10 nM concentration, but secondary cultures reveals that a 100 nM concentration is needed to completely prevent proviral integration.
ln Vitro |
Dapivirine (16 μM, 12-48 h) causes apoptosis and suppresses the growth of glioma cells at concentrations of 4-64 μM, 24, 48, 72, 96, and 120 hours[1]. Glioma cell invasion is enhanced by dapivirine (8 and 16 μM, 12 h)[1]. In U87 cells, dapivirine (16 μM, 12 h, 24 h, and 48 h) stimulates autophagy[1]. In primary cultures, dapivirine (TMC120-R147681) appeared to stop infection at a concentration of 10 nM; however, secondary cultures showed that a 100 nM dosage was required to fully prevent proviral integration[3].

ln Vivo |
In mice with human glioblastoma models, dapivirine (16 mg/kg, once every three days for 12 days) has strong anticancer activity[1]. It has been demonstrated that the half-life of dipivirine is between 65 and 90 hours[4].

Cell Assay |
Cell Proliferation Assay[1]
Cell Types: U87 glioblastoma cells. Tested Concentrations: 4, 8, 16 μM. Incubation Duration: 24, 48, 72, 96 and 120 hrs (hours). Experimental Results: Inhibited proliferation of glioma cells. IC50 was 10.73 μM. Apoptosis Analysis[1] Cell Types: U87 glioblastoma cells. Tested Concentrations: 16 μM. Incubation Duration: 12h, 24h and 48h. Experimental Results: Induced apoptosis. diminished caspase-3. |
Animal Protocol |
Animal/Disease Models: U87 cells were subcutaneously (sc) injected into the nude mice[1].
Doses: 16 mg/kg. Route of Administration: Once every 3 days for 12 days. Experimental Results: Dramatically diminished the tumor volumes. A significant decrease in Ki67 (a marker for proliferating cells that is overexpressed in many cancers) staining in sections of dapivirine-treated tumors compared to tumors from vehicle-treated mice. |
Toxicity/Toxicokinetics |
Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation Dapivirine is investigational in the United States, but available overseas as a vaginal ring for pre-exposure prophylaxis of HIV infections (PrEP). In this dosage form, it is acceptable to use during breastfeeding. ◉ Effects in Breastfed Infants A study compared the dapivirine vaginal ring to emtricitabine plus tenofovir for prophylaxis of HIV infections. Of 148 mother-infant pairs who received the dapivirine vaginal ring, no adverse effects in infants were attributed to dapivirine. ◉ Effects on Lactation and Breastmilk Relevant published information was not found as of the revision date. |

Additional Infomation |
Dapivirine is an investigational drug that is being studied as a topicalmicrobicide to prevent sexual transmission of HIV.
Dapivirine belongs to a class of HIV drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs). NNRTIs attach to and block an HIV enzyme called reverse transcriptase. Dapivirine has been investigated for the prevention of HIV-1 Infections and Topical Penile Exposures. Dapivirine is a diarylpyrimidine non-nucleoside reverse transcriptase inhibitor. Dapivirine has activity against wild-type virus strains and strains harboring different NNRTI resistance-inducing mutations and may have direct virucidal activity. |

Solubility (In Vivo) |
Solubility in Formulation 1: 2.08 mg/mL (6.31 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
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 (6.31 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.) |

*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.
