Thiazolopyrimidines of formula (I): wherein W represents a thiazole ring; R1 and R2 form, together with the N atom to which they are attached, a group of the following formula (IIa): in which A is a ring system; m is 0, 1 or 2; R3 is H or C1-C6 alkyl; and R4 is an indole group which is unsubstituted or substituted; and the pharmaceutically acceptable salts thereof are inhibitors of PI3K and are selective for the p110δ isoform, which is a class Ia PD kinase, over both other class Ia and class Ib kinases. The compounds may 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 function disorders and neurological disorders.
公式(I)的
噻唑嘧啶类化合物:其中W代表
噻唑环;R1和R2与它们所连接的N原子一起形成以下公式(IIa)的基团:其中A是一个环系;m为0、1或2;R3为H或C1-C6烷基;R4为未取代或取代的
吲哚基团;其药学上可接受的盐是
PI3K的
抑制剂,并且是选择性作用于p110δ亚型的类Ia PD激酶,而不是其他类Ia和类Ib激酶。这些化合物可用于治疗由
PI3激酶引起的异常细胞增长、功能或行为所引起的疾病和障碍,如癌症、免疫性疾病、心血管疾病、病毒感染、炎症、代谢/内分泌功能障碍和神经系统障碍。
