A small molecule library of pyrido[2,3-d]pyrimidine-2,4-dione derivatives 6–16 was synthesized from 6-amino-1,3-disubstituted uracils 18, characterized, and screened for inhibitory activity against eukaryotic elongation factor-2 kinase (eEF-2K). To understand the binding pocket of eEF-2K, structural modifications of the pyrido[2,3-d]pyrimidine were made at three regions (R1, R2, and R3). A homology
吡啶并的小分子文库[2,3- d ]嘧啶-2,4-二酮衍生物6 - 16从6-氨基-1,3-二取代的尿嘧啶合成18,其特征在于,并筛选针对真核延伸因子的抑制活性-2 激酶 (eEF-2K)。为了理解eEF-2K的结合口袋,在三个区域(R 1、R 2和R 3)对吡啶并[2,3- d ]嘧啶进行了结构修饰。创建了 eEF-2K 的同源模型,并将化合物6(A-484954,雅培实验室)对接在 eEF-2K 的催化域中。化合物6 (IC 50 = 420 nM) 和 在这个初步系列的吡啶并[2,3- d ]嘧啶类似物中,发现9 (IC 50 = 930 nM)是更好的分子。MDA-MB-231 乳腺癌细胞中的 eEF-2K 活性被化合物6显着降低,被化合物9在较小程度上降低,并且不受化合物12 的影响。当EEF-2K活性是通过2-脱氧刺激类似的抑制效果,观察到d -葡萄糖(2-DOG)的治疗,这
