Biological Activity
Kd: 0.54 nM (Factor D)[1]
Danicopan (ACH-4471) inhibits the proteolytic activity of purified Factor D against its natural substrate Factor B in complex with C3b, blocking production of Bb fragment in a dose-dependent manner with an IC50 value of 0.015 μM[1]. Danicopan (ACH-4471) potently inhibits hemolysis with IC50 values ranging from 0.0040 μM to 0.027 μM (IC90 values from 0.015 μM to 0.11 μM)[1].

Danicopan purchased from MedChemExpress. Usage Cited in: Cancers (Basel). 2022 Jan 8;14(2):305. [Abstract]
cSCC cell cultures (UT-SCC-12A) were treated with a small-molecule factor D inhibitor (danicopan; ACH-4471) or DMSO as vehicle control for 24 h. The levels of complement factor B (FB) and its 60 kDa cleavage derivative in conditioned media of cSCC cells were determined by Western blot analysis.
Danicopan purchased from MedChemExpress. Usage Cited in: Cancers (Basel). 2022 Jan 8;14(2):305. [Abstract]
cSCC cells (UT-SCC-12A) with high basal FD expression levels were treated with small molecule FD inhibitors (danicopan; ACH-4471) or DMSO. Targeted inhibition of FD significantly suppressed cell proliferation.

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 (3.58 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Please enter the basic information of animal experiments:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
