Cabotegravir (GSK-1265744) is a orally active and long-acting HIV integrase strand transfer inhibitor and organic anion transporter 1/3 (OAT1/OAT3) inhibitor with IC₅₀ values of 2.5 nM, 0.41 μM and 0.81 μM for HIV_ADA, OAT3 and OAT1, respectively. Cabotegravir is primarily metabolized by uridine diphosphate glucuronosyltransferase (UGT) 1A1, with low potential to interact with other antiretroviral agents (ARVs). Cabotegravir can be used to research AIDS.

For research use only. We do not sell to patients.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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 90% Corn Oil
Solubility: ≥ 1.67 mg/mL (4.12 mM); Clear solution

This protocol yields a clear solution of ≥ 1.67 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 (16.7 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
