HIV-1 |
In Vitro
BMS-818251 (administered 1 h before infection at 12.5-20 nM) identifies single-amino-acid mutations on the HIV-1 BG505 envelope protein. These mutations cluster around the binding site of BMS-818251 and confer viral resistance to BMS-818251[1].
BMS-818251 (serial dilution starting from 20 μM; 2 days) potently inhibits the entry of HIV-1 NL4-3 pseudovirus into TZM-bl cells, with an EC50 of 0.019 nM[2].
BMS-818251 (serial dilution starting from 20 μM; 2 days) potently neutralizes a panel of 30 cross-subtype HIV-1 primary isolates in TZM-bl cells, with a geometric mean IC50 of approximately 0.002 μM[2].
BMS-818251 (serial dilution starting from 20 μM; 2 days) potently neutralizes a panel of 208 HIV-1 isolates spanning multiple subtype clades in TZM-bl cells, with a geometric mean IC50 of 0.0015 μM and a median IC50 of 0.0005 μM[2].
BMS-818251 binds to purified BG505 DS-SOSIP.664 HIV-1 Env trimer at 37 °C with an affinity of 0.047 μM[2].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5 mg/mL (8.76 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.
