Puromycin aminonucleoside
CAS No. : 58-60-6
MCE 国际站:Puromycin aminonucleoside
产品活性:Puromycin aminonucleoside (NSC 3056) 是一种氨基核苷类抗生素,为嘌呤霉素类似物。Puromycin aminonucleoside 诱导细胞凋亡 (apoptosis)。Puromycin aminonucleoside 可逆抑制二肽基肽酶 (dipeptidyl peptidase II) 和胞浆丙氨酸氨基肽酶。Puromycin aminonucleoside 诱导细胞迁移小体的分泌。
研究领域:Anti-infection | Apoptosis | Metabolic Enzyme/Protease
作用靶点:Bacterial | Apoptosis | Dipeptidyl Peptidase | Aminopeptidase | Antibiotic
In Vitro: Puromycin aminonucleoside (NSC 3056) (30 μg/mL) markedly increases p53 protein levels in podocytes. Puromycin aminonucleoside (NSC 3056)-induced podocyte apoptosis is p53 dependent. Puromycin aminonucleoside (NSC 3056) induces podocyte apoptosis in a time-dependent manner. The IC50 values for PMAT-expressing and vector-transfected cells are 48.9 and 122.1 μM, respectively, suggesting expression of PMAT-enhanced cell sensitivity to Puromycin aminonucleoside. Puromycin aminonucleoside (NSC 3056) (250 μM) is toxic to both PMAT-expressing and vector-transfected cells. Puromycin aminonucleoside (NSC 3056) uptake in PMAT-expressing cells is fourfold higher at pH 6.6 than that at pH 7.4.
In Vivo: The number of podocytes per glomerulus is 95.5±17.6 in the control rats, 90.7 on Day 4 in Puromycin aminonucleoside (NSC 3056) (8 mg/100 g, i.v.)-treated nephrosis rats. The amount of nephrin per glomerulus in control rats is 1.02±0.11 fmol and those in Puromycin aminonucleoside (NSC 3056) nephrosis rats are reduced to 0.46±0.06 fmol and 0.35±0.04 fmol on Day 4 and Day 7. The nephrin amount per podocyte is significantly decreased association with the development of proteinuria in Puromycin aminonucleoside (NSC 3056) nephrosis rats. Rats given Puromycin aminonucleoside (NSC 3056) (100 mg/kg, s.c.) gain less weight and their serum creatinine levels are higher than the control rats.

文献和实验由白黑链霉菌( Streptomyces alboniger)的培养滤液中获得的抗菌素,除对所有细菌具抗性外,还具有抗肿瘤活性。由于其结构与 tRNA的末端结构类似,故能抑制细菌及真核细胞的蛋白质合成。常作为实验用药。它作用于结合在核糖核蛋白体上相应部位的肽酰 tRNA,可使肽酰嘌呤霉素从核糖核蛋白体上游离出来。
嘌呤霉素是一种蛋白质合成抑制剂,它具有与tRNA分子末端类似的结构, 能够同氨基酸结合,代替氨酰化的tRNA同核糖体的A位点结合,并掺入到生长的肽链中。虽然嘌呤霉素能够同A位点结合,但是不能参与随后的任何反应, 因而导致蛋白质合成的终止并释放出C-末端含有嘌呤霉素的不成熟的多肽。
【求助】反复搜寻puromycin resistance protein的分子量大小,仍未果
天心令 本虾米急需知道puromycin resistance protein (puroR)的KDa量是多少 在google上,pubmed上,搜了好些天,都没有搜到 请高手们指点指点 在pubmed的protein上搜索,它有氨基酸数目的显示,但没有分子量的显示。 谢谢各位先 woxingwosu 最好把你的搜索到结果的网页发出来,或者是pubmed的地址,这样才好给你分析。
