  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.

  Replacement of one of the morpholine groups of the phosphatidylinositol 3-kinase (PI3K) inhibitor ZSTK474 (1) with sulfonamide containing substituents produced a new class of active and potent PI3Kα inhibitors. Solubility issues prevented all but the 6-amino derivative 17 from being evaluated in vivo, but the clear activity of this compound demonstrated that this class of PI3K inhibitor shows great

  磷脂酰肌醇3-激酶（PI3K）抑制剂ZSTK474（1）的一个吗啉基团被含磺酰胺的取代基取代产生了新型的活性和有效PI3Kα抑制剂。溶解度问题阻止了除6-氨基衍生物17以外的所有化合物在体内的评估，但该化合物的明显活性表明此类PI3K抑制剂具有广阔的前景。
