(MDA‐MB‐231) and toward the purified recombinant protein. Most of them failed to reach significant inhibition of AMP hydrolysis by CD73 at 100 μm. Among the new compounds, the most interesting candidates, 5 (5′‐deoxy‐5′‐N‐phosphonomethyladenosine) and 7 (5′‐deoxy‐5′‐N‐(ethoxyphosphorylacetate)adenosine), inhibited recombinant CD73 by 36 and 46 % and cellular CD73 by 61 and 45 % at 100 μm, respectively
从关键的中间体5'-氨基核苷合成了5'-氨基腺苷的衍生物,其中包含羧酸甲酯,甲基膦酸酯,双-膦膦酸酯,双(甲基膦酸酯)和α-羧甲基膦酸酯或膦酰基乙酸酯部分。这些核苷酸类似物被设想为5'-单或二磷酸核苷模拟物。在基于细胞的测定(MDA-MB-231)和纯化的重组蛋白中评估了所有化合物对CD73的抑制作用。他们中的大多数失败通过CD73在100μ达到AMP水解的显著抑制米。在新化合物中,最有趣的候选物是5(5'-脱氧-5'- N-膦酰基甲基腺苷)和7(5'-脱氧-5'- N- (ethoxyphosphorylacetate)腺苷),抑制重组CD73由36和46%和细胞CD73由61和45%,在100μ米,分别。分子建模部分地解释了这种缺乏活性的现象,因为最初预测的对接分数令人鼓舞,尤其是对于化合物9而言。
