purine riboside triphosphate

Purine riboside triphosphate, a derivative of purine riboside, exhibits structural similarity to adenosine. This naturally occurring base analog possesses inhibitory effects on carcinogenic growth, particularly in cancer ascites cells, by strongly impeding RNA and DNA synthesis.

Purine riboside-5'-O-triphosphate sodium 是 Nebularine (HY -103694) 的活性代谢产物，作为 DNA 引物酶 ATP 和 GTP 聚合活性的抑制剂，其IC50值分别为 35 µM 和 28 µM。此外，Purine riboside-5'-O-triphosphate sodium 还能抑制钙调素依赖性蛋白激酶II (calmodulin-dependent protein kinase II (CaMKII))，其Ki值为 590 µM。
