Fused pyrimidines of formula (I): wherein R-R, A and n have any of the values described in the specification; and pharmaceutically acceptable salts thereof; have activity as inhibitors of PI3K and may thus be used to treat diseases and disorders arising from abnormal cell growth, function or behaviour associated with PI3 kinase such as cancer, immune disorders, cardiovascular disease, viral infection, inflammation, metabolism/endocrine disorders and neurological disorders. Processes for synthesizing the compounds are also described.

Pharmaceutical compounds

Thienopyrimidines of formula (Ia) or (Ib): wherein R-Rhave any of the values described herein, and the pharmaceutically acceptable salt thereof have activity as inhibitors of PI3K and may thus be used to treat diseases and disorders arising from abnormal cell growth, function or behaviour associated with PI3 kinase, in particular the p110 delta subtype, such as immune disorders, cardiovascular disease, viral infection, inflammation, metabolism/endocrine disorders and neurological disorders. Processes for synthesizing the compounds are also described.

Pyrimidine derivatives as PI3K inhibitors

Fused pyrimidines of formula (I): wherein R-R, A and n have any of the values described in the specification; and pharmaceutically acceptable salts thereof; have activity as inhibitors of PI3K and may thus be used to treat diseases and disorders arising from abnormal cell growth, function or behavior associated with PI3 kinase such as cancer, immune disorders, cardiovascular disease, viral infection, inflammation, metabolism/endocrine disorders and neurological disorders. Processes for synthesizing the compounds are also described.

Provided herein are methods of treating diseases or disorders arising from abnormal cell growth, function or behavior associated with PI3 kinase, which method includes administering to a patient in need thereof a compound that is a fused pyrimidine of formula (I): 

Fused pyrimidines of formula (I): where A is a thiophene or furan ring and R-Rand n are defined in the specification. These compounds have activity as inhibitors of PI3K and may thus be used to treat diseased and disorders arising from abnormal cell growth, function or behavior associated with PI3 kinase such as cancer, immune disorders, cardiovascular disease, viral infection, inflammation, metabolism/endocrine disorders and neurological disorders. Processes for synthesizing the compounds are also described.

Fused pyrimidines of formula (I): wherein R-R, A and n have any of the values described in the specification; and pharmaceutically acceptable salts thereof, have activity as inhibitors of PI3K and may thus be used to treat diseases and disorders arising from abnormal cell growth, function or behaviour associated with PI3 kinase such as cancer, immune disorders, cardiovascular disease, viral infection, inflammation, metabolism/endocrine disorders and neurological disorders.
