Hazard Information | Back Directory | [Description]
Umbralisib (TGR-1202) tosylate is an orally active, potent and selective dual PI3Kδ and casein kinase-1-ε (CK1ε) inhibitor, with EC50
of 22.2 nM and 6.0 μM, respectively. Umbralisib tosylate exhibits
unique immunomodulatory effects on chronic lymphocytic leukemia (CLL) T
cells. Umbralisib tosylate can be used for haematological malignancies
reseach. | [Uses]
RP 5264 is a novel PI3K inhibitor that enhances Brentuximab Vedotin-induced lymphoma cell death. | [Brand name]
Ukonig | [General Description]
Class: lipid kinase;
Treatment: MZL, FL;
Other name: TGR-1202;
Elimination half-life = 91 h;
Protein binding > 99.7% | [Pharmacokinetics]
Umbralisib has a prolonged half-life of 91 h,
which enables once-daily dosing. However, the
recommended dosage of 800 mg is the highest
among all the PI3K inhibitors in use, presumably due
to its limited oral bioavailability. | [Synthesis]
The synthesis of Umbralisib is as follows: To a solution of intermediate 13 (0.134 g, 0.494 mmol) in THF (2.0 ml), intermediate 5 (0.150 g, 0.494 mmol) and triphenylphosphine (0.194 g, 0.741 mml) were added and stirred at RT for 5 min. Diisopropylazodicarboxylate ( 0.15 ml, 0.749 mmol) was added heated to 45°C. After 2h, the reaction mixture was quenched with with water and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography with ethyl acetate : petroleum ether to afford Umbralisib as an off-white solid (0.049 g, 20 %).
