Selective dual inhibitors of PI3 delta and gamma protein kinases
The present invention relates to a selective dual delta (δ) and gamma (γ) PI3K protein kinase modulator (S)-N-(5-(4-amino-1-(1-(5-fluoro-3-(3-fluorophenyl)-4-oxo-4H-chromen-2-yl)ethyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-methoxyphenyl) methane sulfonamide, methods of preparing them, pharmaceutical compositions containing them and methods of treatment, prevention and/or amelioration of PI3K kinase mediated diseases or disorders with them.
1. A method of treating leukemia in a patient in need thereof, comprising administering to the patient an effective amount of (S)-N-(5-(4-amino-1-(1-(5-fluoro-3-(3-fluorophenyl)-4-oxo-4H-chromen-2-yl)ethyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-methoxyphenyl)methanesulfonamide or a pharmaceutically acceptable salt thereof.
2. A method of treating chronic lymphocytic leukemia (CLL), non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL) acute myeloid leukemia (AML), multiple myeloma (MM), small lymphocytic lymphoma (SLL), or indolent non-Hodgkin's lymphoma (I-NHL) disease in a patient in need thereof, the method comprising administering to the patient an effective amount of (S)-N-(5-(4-amino-1-(1-(5-fluoro-3-(3-fluorophenyl)-4-oxo-4H-chromen-2-yl)ethyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-methoxyphenyl)methane sulfonamide or a pharmaceutically acceptable salt thereof.
3. A method for the treatment of leukemia, acute lymphocytic leukemia, acute lymphoblastic leukemia, B-cell lymphoma, T-cell lymphoma, Hodgkin's lymphoma, non-Hodgkin's lymphoma, hairy cell lymphoma, Burkett's lymphoma, acute or chronic myelogenous leukemia, myelodysplastic syndrome, promyelocytic leukemia, osteoarthritis, allergic rhinitis, or lupus erythematosus comprising administering to a subject in need thereof an effective amount of (S)-N-(5-(4-amino-1-(1-(5-fluoro-3-(3-fluorophenyl)-4-oxo-4H-chromen-2-yl)ethyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-methoxyphenyl)methanesulfonamide or a pharmaceutically acceptable salt thereof.
4. The method of claim 3 , further comprising administering an additional active agent selected from anti-cancer agents, anti-inflammatory agents, immunosuppressive agents, steroids, non-steroidal anti-inflammatory agents, antihistamines, analgesics, and mixtures thereof.
5. A process for the preparation of compound of formula (I)
comprising the steps of:
(a) reacting 5-bromo-2-methoxyaniline with methane sulphonyl chloride
to give N-(5-bromo-2-methoxyphenyl)methanesulfonamide (Intermediate 1)
(b) reacting Intermediate 1 with bis(pinacolato)diboron to give N-(2-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methanesulfonamide (Intermediate 2)
and
(c) reacting 2-(1-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl)-5-fluoro-3-(3-fluorophenyl)-4H-chromen-4-one
with intermediate 2 in the presence of a suitable base to give a compound of formula (I).
