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 ?M (HIV-1, A018 isolate). 3-Deazaadenosine (hydrochloride) is an inhibitor of S-adenosylhomocysteine hydrolase, with a Ki of 3.9 ?M. |
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 ?M) 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 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 after balloon injury the intima/media ratio in the c3Ado-treated group was reduced by 67% and luminal stenosis by 50%. Neointimal cellular density was decreased by 25% and the induction of c-Jun and ki67 was markedly lower. |
产品描述 | 3-Deazaadenosine (hydrochloride) is an inhibitor of S-adenosylhomocysteine hydrolase, with a Ki of 3.9 µM[1]. 3-Deazaadenosine dose-dependently prevented the proliferation and migration of human coronary VSMCs in vitro. This was accompanied by an increased expression of the cyclin-dependent kinase inhibitors p21(WAF1/Cip1), p27(Kip1), a decreased expression of G(1)/S phase cyclins, and a lack of retinoblastoma protein hyperphosphorylation. [3]. In the mouse macrophage cell line, RAW264. S-Adenosylhomocysteine accumulated in cells incubated with 3-deazaaristeromycin while S-3-deazaadenosylhomocysteine was the major product in cells incubated with 3-Deazaadenosine and homocysteine thiolactone[4].200 microM 3-Deazaadenosine (c3Ado) prevented this TNF-induced increase in HEC adhesiveness. This effect resulted from interactions of 3-Deazaadenosine with HEC and not with polymorphonuclear neutrophils[5]. 3-Deazaadenosine (DZA), an adenosine analogue, prevented high methionine-induced ICAM-1 and VCAM-1 expression and collagen type-1 synthesis.in vitro 3-Deazaadenosine and CBS gene therapy successfully treated the HHcy-induced inflammatory reaction in the methionine metabolism pathway[6]. 3-Deazaadenosine (c3Ado) inhibits atherogenesis in mice. Sprague Dawley rats underwent balloon angioplasty. 3-Deazaadenosine was administered orally, starting 5 days prior to the balloon injury and continued for 2 weeks. Fourteen days after balloon injury the intima/media ratio in the c3Ado-treated group was reduced by 67% and luminal stenosis by 50%. Neointimal cellular density was decreased by 25% and the induction of c-Jun and ki67 was markedly lower. Short-term administration of C3Ado inhibits neointima-formation in rats for at least 3 months after injury[7]. References: |
