Cluster of differentiation 73 (CD73) converts adenosine 5'-monophosphate to immunosuppressive adenosine, and its inhibition was proposed as a new strategy for cancer treatment. We synthesized 5'- O-[(phosphonomethyl)phosphonic acid] derivatives of purine and pyrimidine nucleosides, which represent nucleoside diphosphate analogues, and compared their CD73 inhibitory potencies. In the adenine series
分化簇73(CD73)将5'-单磷酸腺苷转化为免疫抑制腺苷,其抑制作用被提出作为一种新的癌症治疗策略。我们合成了嘌呤和嘧啶核苷的5'-O-[(膦酰基甲基)膦酸]衍生物,它们代表核苷二磷酸类似物,并比较了它们对CD73的抑制作用。在腺嘌呤系列中,大多数核糖修饰和1-deaza和3-deaza都是有害的,但可以容忍7-deaza。耐受尿嘧啶被N3-甲基取代,但不能被较大的基团或2-硫代取代。不容许1,2-二膦酰基-乙基修饰。N4-(芳基)烷氧基-胞嘧啶衍生物,特别是具有庞大的苄氧基取代基的化合物,显示出增强的效力。最有效的抑制剂是5' -5-氟尿苷(4l),N4-苯甲酰基胞苷(7f),N4- [O-(4-苄氧基)]胞苷(9h)和N4- [O的O-[(膦酰基甲基)膦酸]衍生物-(4-萘-2-基甲氧基)]-胞苷(9e)(在人CD73上Ki值为5-10 nM)。在两种尿苷二磷酸激活的P2Y受体亚型上
