Adenosine dialdehyde, a purine nucleoside analogue, is a potent inhibitor of S-Adenosylhomocysteine hydrolase (SAHH) (K_i=3.3 nM)^[1]. Adenosine Dialdehyde exhibits potent anti-tumor activity in vivo and can be used for the cancer research^[1][2].

Adenosine dialdehyde suppresses MNB cell replication in tissue culture with concentra tions of 1.5 μM with producing 50% inhibition^[2].

Adenosine dialdehyde (subcutaneous injection; 1.5-2.5 mg/kg; infused over a 7-day period ( minipump infusion)) significantly increases the mean life span of tumor bearing mice from 20.9 days in diluent treated controls to 35.3 days in AD treated animals^[3].
Adenosine dialdehyde (subcutaneous injection; 1.5-2.5 mg/kg; two 7-day periods interspersed by a 7-day drug free interval( minipump infusion))increases mean life span 80% in diluent treated controls (controls, 21.3 days; AD treated 38.4 days) in mice^[3].
Adenosine dialdehyde (subcutaneous injection; 2-3 mg/kg; infused over a 7-day period ( minipump infusion)) does not exhibit any hematopoietic toxicity in mice, and it can significantly suppress murine neuroblastoma tumor growth with little systemic toxicity^[3].
