FD223 |
| Catalog No.GC62973 |
FD223 est un inhibiteur puissant et sélectif de la phosphoinositide 3-kinase delta (PI3Kδ). FD223 affiche une puissance élevée (IC50 = 1 nM) et une bonne sélectivité par rapport aux autres isoformes (IC50 de 51 nM, 29 nM et 37 nM, respectivement pour α, β et γ). FD223 présente une inhibition efficace de la prolifération des lignées cellulaires de leucémie myéloÏde aiguë (LMA) en supprimant p-AKT Ser473, provoquant ainsi un arrêt de la phase G1 au cours du cycle cellulaire. FD223 a un potentiel pour la recherche sur la leucémie telle que la LAM.

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[1].
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].
FD223 (20 and 40 mg/kg; p.o, per day for 14 consecutive days) displays potent antitumor efficacy in MOLM-16 xenograft model with the tumor volume reduction of 49% at a dose of 40 mg/kg/day (po), and shows no significant toxicity in the preliminary safety assessment[1].FD223 (i.v.; dose of 2 mg/kg; p.o.; 10 mg/kg rats) shows a moderate plasma clearance rate after intravenous administration with C =0.191 L•h-1•kg-1. In the po route, it shows a half-life (t1/2) of 3.74 h and a Cmax of 1104 ng/mL, good oral plasma exposures (AUC0-∞>9000 h•ng/mL) and acceptable oral bioavailability (17.6%)[1].
