FD223

Customer Review

Based on 1 Customer Validation

FD223 is a potent and selective phosphoinositide 3-kinase delta (PI3Kδ) inhibitor. FD223 displays high potency (IC₅₀=1 nM) and good selectivity over other isoforms (IC₅₀s of 51 nM, 29 nM and 37 nM, respectively for α, β and γ). FD223 exhibits efficient inhibition of the proliferation of acute myeloid leukemia (AML) cell lines by suppressing p-AKT Ser473 thus causing G1 phase arrest during the cell cycle. FD223 has potential for the research of leukemia such as AML.

In Vitro

FD223 exhibits notable anti-proliferative activities in the p110δ-positive AML cell lines HL-60, MOLM-16, EOL-1 and KG-1, with the IC₅₀ of 2.25 μM, 0.87 μM, 2.82 μM, and 5.82 μM, respectively. FD223 shows weak anti-proliferative activity against p110δ unexpressed MM.1R cell line, with the IC50 value of 23.13 μM^[1].
FD223 (MOLM-16 cells; 0.1-5 μM; 16 hours) dose-dependently reduces phosphorylation of Akt (Ser473), which is consistent with the positive control Idelalisib, illustrating that the activity of PI3K/Akt pathway in MOLM-16 cell is blocked^[1].
FD223 (MOLM-16 cells; 24 hours; 1-5 μM) arrests the cell cycle at the G1 phase similar to that of positive control Idelalisib^[1].
FD223 (1-5 μM; 48 hours) dose-dependently induces cellular apoptosis^[1].

Stock Solution Working Solution

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 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (6.48 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: 2.5 mg/mL (6.48 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
