Broxyquinoline
Based on 2 publication(s) in Google Scholar
Broxyquinoline (Dibromohydroxyquinoline) is an effective inhibitor of severe fever with thrombocytopenia syndrome virus (SFTSV) with an IC50 of 5.8 µM. Additionally, Broxyquinoline is an inhibitor of CpACBP1 with an IC50 of 64.9 μM. CpACBP1 is a fatty acyl-CoA binding protein of Cryptosporidium parvum, thus Broxyquinoline has the potential to inhibit parasite growth. Broxyquinoline shows promise for research in the field of infectious diseases.

Biological Activity
Broxyquinoline (1 mM, 10 μM, 44 h) has almost no active effect on Human ileocaecal colorectal adenocarcinoma (HCT-8) cells[1]. Broxyquinoline (0-1.0 mM, 44 h) exhibits antiparasitic activity in vitro[1]. Broxyquinoline (10 μM, 72 h) does not show significant toxicity to Vero cells and exhibits activity against severe fever with thrombocytopenia syndrome virus (SFTSV) [2].

Solvent & Solubility
DMSO : 31.25 mg/mL (103.15 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: 2.08 mg/mL (6.87 mM); Suspended solution; Need ultrasonic
