Dimorpholinopyrimidines are useful for inhibiting growth or proliferation of hamartoma tumor cells. Because the Dimorpholinopyrimidines inhibit the growth and proliferation of hamartoma tumor cells they are also useful in treating PTEN hamartoma tumor syndromes. The therapeutic and prophylactic treatments provided by this invention are practiced by administering to a patient in need thereof an amount of a compound of dimorpholinopyrimidine derivative that is effective to inhibit growth or proliferation of the hamartoma tumor cells.
                            Dimorpholinopyrimidines具有抑制错构瘤肿瘤细胞生长或增殖的作用。由于Dimorpholinopyrimidines抑制错构瘤肿瘤细胞的生长和增殖,因此它们也可用于治疗
PTEN错构瘤肿瘤综合症。本发明提供的治疗和预防治疗是通过向需要治疗的患者施用有效抑制错构瘤肿瘤细胞生长或增殖的Dimorpholinopyrimidine衍
生物化合物的量来实施的。
