  Synthesis and Biological Evaluation of Novel Analogues of the Pan Class I Phosphatidylinositol 3-Kinase (PI3K) Inhibitor 2-(Difluoromethyl)-1-[4,6-di(4-morpholinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (ZSTK474)

  摘要：

  A structure activity relationship (SAR) study of the pan class I PI 3-kinase inhibitor 2-(difluoromethyl)-1-[4,6-di(4-morpholinyl)-1,3,5-triazin-2-yl]-1H-benzimidazole (ZSTK474) identified substitution at the 4 and 6 positions of the benzimidazole ring as having significant effects on the potency of substituted derivatives. The 6-amino-4-methoxy analogue displayed a greater than 1000-fold potency enhancement over the corresponding 6-aza-4-methoxy analogue against all three class Ia PI 3-kinase enzymes (p110 alpha, p110 beta, and p110 delta) and also displayed significant potency against two mutant forms of the p110 alpha isoform (H1047R and E545K). This compound was also evaluated in vivo against a U87MG human glioblastoma tumor xenograft model in Ragl(-/-) mice, and at a dose of 50 mg/kg given by ip injection at a qd x 10 dosing schedule it dramatically reduced cancer growth by 81% compared to untreated controls.

  Provided herein are substituted pyrimidine and triazine derivatives, including bicyclic pyrimidine derivatives, their pharmaceutical compositions, their preparation, and their use as agents or drugs for cancer therapy, either alone or in combination with radiation and/or other anticancer drugs. In one embodiment, the pyrimidine and triazine derivatives are morpholino-pyrimidine, morpholino-triazine, pyridyl-pyrimidine, and pyridyl-triazine derivatives which are selective irreversible inhibitors of the p110α isoform of PI3K.

  本文提供了替代嘧啶和三嗪衍生物，包括双环嘧啶衍生物，它们的药物组合物，其制备以及它们作为单独的癌症治疗剂或药物的用途，或与放射线和/或其他抗癌药物组合使用。在一种实施例中，嘧啶和三嗪衍生物是吗啡啶基嘧啶，吗啡啶基三嗪，吡啶基嘧啶和吡啶基三嗪衍生物，它们是PI3K的p110α亚型的选择性不可逆抑制剂。
