Herein, we describe new quinazoline and tetrahydropyridothieno[2,3-d]pyrimidine derivatives with an acrylamido group at positions 6 and 7 respectively, and with variable anilino, sulfonamido and cycloalkylamino substituents at position 4. The lipophilic and steric properties of the position 4 substituent seem crucial for activity. Several compounds were more active than gefitinib in inhibiting the
在这里,我们描述了新的喹唑啉和四氢吡啶并噻吩并[2,3- d ]嘧啶衍生物,分别在位置6和7具有丙烯酰胺基,在位置4具有可变的苯胺基,磺酰胺基和环烷基氨基取代基。位置4的亲脂性和空间性取代基似乎对活性至关重要。几种化合物比吉非替尼 在抑制野生型EGFR酶,表达突变型EGFR的细胞系(H1975)的自磷酸化以及具有野生型和突变型EGFR的细胞系的生长中 酪氨酸激酶。此外,描述了由甲亚氨酸酯衍生物新颖合成喹唑啉核。
