  Synthesis of 2-Chloro-6-aryloxy- and 2-Chloro-6-alkoxyarylpurines and Their Properties in the Purine Nucleoside Phosphorylase (PNP) System

  摘要：

  A seri es of 2-chloro-6-aryloxy- and 2-chloro-6-alkoxyarylpurines was synthesized and their kinetic properties in the purine nucleoside phosphorylase (PNP) system were determined. All compounds showed inhibitory activity (IC50 in the range 0.5-76 mu M) vs. hexameric ("high-molecular weight") PNP from E. coli. By contrast, no inhibition vs. trimeric Cellulomonas PNP was detected.

  The present invention relates to nucleotides, analogs of mRNA 5'-end (cap) containing sulfur atom at the position 5' of 7-methylguanosine nucleoside. The disclosed compounds are recognized (bound and non-hydrolyzed) by DcpS enzyme (Decapping Scavenger), and thus may find therapeutic use as inhibitors thereof. DcpS is cap-specific enzyme with pyrophosphatase activity, which was identified as a therapeutic target in the treatment of spinal muscular atrophy (SMA). Some of the compounds disclosed have additional modifications in the phosphate chain, wh ich modulate their affinity for DcpS enzyme. The present invention also relates to mRNAs modified at the 5' end with mRNA 5'-end (cap) analogs containing 5'- phosphorothiolate moiety, which mRNAs have an increased stability and translational activity in cellular conditions, to a method of their preparation, their uses, and to a pharmaceutical formulation containing them, wherein L1 and L2 are independently selected from the group comprising O and S, wherein at least one of L1 and L2 is not O.

  本发明涉及核苷酸，含有硫原子的mRNA 5'-端（帽子）的类似物，在7-甲基鸟苷核苷酸的5'位置。所公开的化合物被DcpS酶（去帽清道夫）识别（结合并不水解），因此可能作为其抑制剂在治疗中发挥作用。DcpS是帽子特异性酶，具有焦磷酸酶活性，已被确定为治疗脊髓性肌萎缩（SMA）的治疗靶点。所公开的一些化合物在磷酸链中具有额外的修饰，调节它们对DcpS酶的亲和力。本发明还涉及在mRNA的5'端修饰了含有5'-磷硫酸酯基团的mRNA 5'-端（帽子）类似物的mRNAs，这些mRNAs在细胞条件下具有增强的稳定性和翻译活性，以及它们的制备方法，用途和含有它们的制药配方，其中L1和L2分别选择自包括O和S的组中，其中至少一个L1和L2不是O。
