s-adenosylhomocysteine hydrolase

Adenosine Dialdehyde (Periodate-oxidized adenosine) is a purine nucleoside analogue. Adenosine Dialdehyde is a potent inhibitor of S-Adenosylhomocysteine hydrolase (SAHH) (Ki=3.3 nM). Adenosine Dialdehyde exhibits potent anti-tumor activity in vivo.

3-Deazaneplanocin A (DZNep) is a dual inhibitor of histone methyltransferase (EZH2) and S-adenosylhomocysteine hydrolase (AHCY) with antipoxidative activity that inhibits hepatic, renal, peritoneal, and airway fibrosis by inducing proteasomal degradation of its targets and reducing toxicity in animal models.

S-Adenosylhomocysteine (SAH) hydrolase is responsible for the reversible hydrolysis of SAH into adenosine and homocysteine. Inhibition of this enzyme leads to the accumulation of SAH within cells, thereby increasing the SAH to S-adenosylmethionine (SAM) ratio and subsequently inhibiting SAM-dependent methyltransferases. (−)-Neplanocin A, a potent and irreversible inhibitor of SAH hydrolase (Ki= 8.39 nM), exhibits significant antitumor activity against mouse leukemia L1210 cells and holds broad-spectrum antiviral properties. Its efficacy notably surpasses that of the reversible inhibitor 3-deazaneplanocin, especially in combating vesicular stomatitis, evidencing a higher potency with ID50 values of 0.07 μg/ml for Neplanocin A versus 0.3 μg/ml for 3-deazaneplanocin.

3-Deazaadenosine, an inhibitor of S-adenosylhomocysteine hydrolase with a Ki of 3.9 μM, exhibits anti-inflammatory, anti-proliferative, and anti-HIV activity.

Aristeromycin diphosphate is an inhibitor of S-adenosylhomocysteine hydrolase (AHCY), inducing miR-26a and regulating oncogenic EZH2 expression, showing high inhibitory activity against AHCY, and causing growth inhibition of prostate cancer.

3-Deazaadenosine hydrochloride is an inhibitor of S-adenosylhomocysteine hydrolase (Ki: 3.9 µM). It has anti-inflammatory, anti-proliferative, and anti-HIV activity.

Aristeromycin (U 99468) is a broad-spectrum antiviral antibiotic that targets RNA viruses and is an inhibitor of S-adenosylhomocysteine hydrolase (AHCY).

3-deazaneplanocin A (DZNeP)HCl, an analog of adenosine, is a competitive inhibitor of S-adenosylhomocysteine hydrolase with Ki of 50 pM.
