Purity: ≥98%
Dolutegravir (formerly also known as GSK1349572; GSK-1349572; Tivicay) is a novel, potent and orally bioavailable two-metal-binding HIV integrase inhibitor approved to treating HIV infections. It inhibits HIV integrase with IC50 of 2.7 nM in a cell-free assay. Dolutegravir has been approved by FDA for use in combination with other medications for the treatment of HIV/AIDS infection. It demonstrated modest activity against raltegravir-resistant signature mutants Y143R, Q148K, N155H, and G140S/Q148H. It is used for the treatment of HIV-infected adults who have never received any HIV therapy (treatment-naïve) and HIV-infected adults who have previously taken HIV therapy (treatment-experienced). It may also be used, as part of post exposure prophylaxis, to prevent HIV infection following potential exposure.
| ln Vitro |
Dolutegravir (S/GSK1349572) has an EC50 of 0.51 nM against HIV-1 in PBMCs, 0.71 nM in MT-4 cells, and 2.2 nM in the pseudotyped self-inactivating virus (PHIV) assay. Dolutegravir's 50% cytotoxic concentrations (CC50) in proliferating IM-9, U-937, MT-4, and Molt-4 cells are, in order, 4.8, 7.0, 14, and 15 μM. The CC50 values in unstimulated and stimulated PBMCs are 189 μM and 52 μM, in that order. Dolutegravir's 0.51 nM EC50 against HIV-1 in PBMCs indicates that a cell-based therapeutic index of at least 9,400 is required[1].

| ln Vivo |
In rats (0.23 mL/min/kg) and monkeys (2.12 mL/min/kg), the plasma clearance after a single intravenous (IV) dose of dolutegravir is low. Both the rat and monkey have half-lives of roughly six hours, and their steady-state volume of distribution (VSS) is small. When given orally as a solution to one male monkey and five fast-fasting rats, dolutegravir is highly bioavailable and quickly absorbed (75.6 and 87.0%, respectively). After oral administration of a suspension to non-fasted rats up to 250 mg/kg and non-fasted monkeys up to 50 mg/kg, dolutegravir exposure (Cmax and AUC) increased with increasing dose, however the rise is less than proportional[3].

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
