  Inhibition of Adenosine Deaminase by Analogues of Adenosine and Inosine, Incorporating a Common Heterocyclic Base, 4(7)-Amino-6(5)H-imidazo[4,5-d]pyridazin-7(4)one

  摘要：

  Four nucleoside analogues (1-4) containing a common heterocyclic base, 4(7)-ammo-6(5)H-imidazo[4,5-d]pyridazin-7(4)one, were screened against calf-intestine adenosine deaminase. Compounds I and 3 with K-i values of 10-12 mu M are more than four times as potent inhibitors of ADA compared with 2 and 4, with K-i values of 51-52 mu M. Also, 3 is not a substrate of ADA. Nucleosides 3 and 4 also exhibit moderate in vitro activity against breast cancer cell lines, while all four are only minimally or nontoxic to the normal cells.
