3-Deazaadenosine (Synonyms: 3-脱氮腺苷)

Kinase experiment [1]: 

Preparation Method Prior to use, the [8-14C] adenosine was checked for purity using isocratic HPLC elution. The assay incubation mixture contained 0.4 IU of enzyme in 50 L. The metabolites were separated by thin-layer chromatography. The radioactivity was quantitated by cutting the plastic backed TLC plates and placing them in scintillation vials, and counting in a Packard 2000 CA scintillation counter 

Applications IC50: 0.15 (HIV-1, A012 isolate), 0.20 µM (HIV-1, A018 isolate). 3-Deazaadenosine (hydrochloride) is an inhibitor of S-adenosylhomocysteine hydrolase, with a Ki of 3.9 µM. 

Cell experiment [2]: 

Cell lines Mouse macrophage RAW 264.7 

Preparation Method RAW 264.7 cells were pretreated with or without 3-Deazaadenosine (100 μMM) for 1 h, and stimulated by the addition of LPS (1 μg/ml). After incubation for 1 h, the cells were washed, and p65 was recovered by immunoprecipitation with anti-p65 and protein A-Sepharose. 

Reaction Conditions 0-100 μM 3-Deazaadenosine for 1 hour 

Applications 3-Deazaadenosine (1-100 ?M) inhibits LPS-induced expression of TNF-α mRNA, increases DNA binding activity of NF-κB, and causes proteolytic degradation of IκBα, but Not IκBβ in RAW 264.7 cells. 3-Deazaadenosine (100 µM) enhances nuclear translocation of NF-κB, but blocks LPS-induced NF-κB transcriptional activity, and such inhibition is augmented by the addition of homocysteine. 

Animal experiment [3]: 

Animal models Male, healthy Sprague–Dawley rats (300‿50 g) 

Preparation Method Animals and balloon injury: rats were fed for 5 days prior and 14 days after the balloon injury with standard chow containing c3Ado at a concentration of 10 mg/kg 3-Deazaadenosine body weight. 

Dosage form 10 mg/kg 3-Deazaadenosine for 5 days prior and 14 days after the balloon injury 

Applications 3-deazaadenosine (c3Ado) inhibits atherogenesis in mice. Sprague Dawley rats underwent balloon angioplasty. C3Ado was administered orally, starting 5 days prior to the balloon injury and continued for 2 weeks. Fourteen days afte
