[CAS NO. 34240-05-6]  Adenosine Dialdehyde (ADOX)

Adenosine dialdehyde (AdOx), an indirect inhibitor that can be incorporated by cells. AdOx inhibits S-adenosyl-L-homocystein hydrolase, resulting in the accumulation of S-adenosyl-L-homo cystein (Adoicy), a product inhibitor of methyltransferases that utilize S-adenosyl-L-methionine (AdoMet) as the methyl group donor. AdOx inhibited the Tax-activated NF-κB pathway, resulting in reactivation of p53 and induction of p53 target genes. Analysis of the NF-κB pathway demonstrated that AdOx treatment resulted in degradation of the IκB kinase complex and inhibition of NF-κB through stabilization of the NF-κB inhibitor IκBα. AdOx induced G2/M cell cycle arrest and cell death in HTLV-1-transformed but not control lymphocytes.
