  Identification of Orally Active, Potent, and Selective 4-Piperazinylquinazolines as Antagonists of the Platelet-Derived Growth Factor Receptor Tyrosine Kinase Family

  摘要：

  We have previously found that the 4-[4-(N-substituted carbamoyl)-1-piperazinyl]-6,7-dimethoxyquinazolines can function as potent and selective inhibitors of platelet-derived growth factor receptor (PDGFR) phosphorylation. A series of highly potent, specific, orally active, small molecule kinase inhibitors directed against members of PDGFR receptor have been developed through modifications of the novel quinazoline template I. Systematic modifications in the A-bicyclic ring and D-rings of protype I were carried out to afford potent analogues, which display IC50 values of <250 nM in cellular betaPDGFR phosphorylation assays. An optimized analogue in this series, 75 (CT53518), inhibits Flt-3, betaPDGFR, and c-Kit receptor phosphorylation with IC50 values of 50-200 nM, whereas 15-20-fold less potent activity against CSF-1R was observed. This analogue also inhibits autophosphorylation of Flt-3 ligand-stimulated wild-type Flt-3 and a constitutively activated Flt-3/internal tandem duplication (ITD) with IC50 values of 30-100 nM. Through this optimization process, 75 was found to be metabolically stable and has desirable pharmacokinetic properties in all animal species studied (F% > 50%, T-1/2 > 8 h). Oral administration of 75 promotes mice survival and significantly delayed disease progression in a Flt-3/ITD-mediated leukemia mouse model and shows efficacy in a nude mouse model of chronic myelomonocytic leukemia.

  摘要：

  我们以前曾报道过，一系列的4- [4-（N-取代的（硫代）氨基甲酰基）-1-哌嗪基] -6,7-二甲氧基喹唑啉衍生物是有效的和选择性的血小板衍生生长因子受体（PDGFR）磷酸化抑制剂。并证明了多种生物学效应，例如通过口服给药抑制大鼠颈动脉球囊损伤后新内膜的形成。在这里，我们研究了6,7-二甲氧基喹唑啉基部分的结构活性关系。关于6,7-二甲氧基，乙氧基类似物显示出有效的活性（16b的IC（50）为0.04 microM； 17a的IC（50）为0.01 microM），烷基的进一步延伸降低了活性。有趣的是，甲氧基乙氧基（16j的IC（50）为0.02 microM; 17h的IC（50）为0.01 microM）和乙氧基乙氧基（17j的IC（50）为0。02 micro M）类似物显示出最有效的活性，表明插入的氧原子与β-PDGFR显着相互作用。在三环喹唑啉衍生物中，2-氧代咪唑并[4,5-

  Based on the potent phosphodiesterase 10 A (PDE10A) inhibitor PQ‐10, we synthesized 32 derivatives to determine relationships between their molecular structure and binding properties. Their roles as potential positron emission tomography (PET) ligands were evaluated, as well as their inhibitory potency toward PDE10A and other PDEs, and their metabolic stability was determined in vitro.
