report the discovery and synthesis of a novel series of dihydrothieno- and dihydrofuropyrimidines (2 and 3) as potent pan Akt inhibitors. Utilizing previous SAR and analysis of the amino acid sequences in the binding site we have designed inhibitors displaying increased PKA and general kinase selectivity with improved tolerability compared to the progenitor pyrrolopyrimidine (1). A representative dihydrothieno
在这里,我们报告发现和合成新型的二氢噻吩并二氢呋喃嘧啶(2和3)作为有效的泛Akt抑制剂。通过使用先前的SAR和结合位点的氨基酸序列分析,我们设计了与祖细胞吡咯并嘧啶相比具有更高的PKA和一般激酶选择性且具有更高耐受性的抑制剂(1)。代表性的二氢噻吩诺化合物(34)进入PC3-NCI前列腺小鼠肿瘤模型,在该模型中,当每天口服200 mg / kg时,它表现出剂量依赖性的肿瘤生长和停滞减少。
