derivatives (compounds 2a-m) incorporating different chemical moieties on the benzyl ring. Compounds 2a-m show in vitro antiproliferative activity in U87MG glioma cells and, analogous to the bisphosphonate FPPS inhibitors, exhibit immunogenic properties in ex vivo γδ T cells from stimulated peripheral blood mononuclear cells (PBMCs). Using saturation transfer difference (STD) and quantitative 1H nuclear
法呢基焦磷酸合酶(FPPS)是合成类异戊二烯的关键酶,也是含氮双膦酸酯(N-BPs)的关键靶标。N-BPs是有效的选择性FPPS抑制剂,用于治疗骨相关疾病,但药代动力学性能较差。鉴于FPPS在许多与癌症相关的途径中所起的关键作用以及N-BP的药代动力学极限,已筛选出数百种分子以鉴定新的FPPS抑制剂,这些抑制剂具有改善的类药物特性,可用于固体中更广泛的治疗应用,非骨骼肿瘤。先前我们已经表明,N6-异戊烯基腺苷(i6A)及其相关化合物N6-苄基腺苷(2)通过干扰甲羟戊酸途径和抑制FPPS发挥抗神经胶质瘤活性。这里,我们报道了一组N6-苄基腺苷衍生物(化合物2a-m)的设计和合成,该衍生物在苄基环上结合了不同的化学部分。化合物2a-m在U87MG胶质瘤细胞中显示体外抗增殖活性,类似于双膦酸酯FPPS抑制剂,在刺激的外周血单核细胞(PBMC)的离体γδT细胞中显示免疫原性。使用饱和转移差异(ST
