产品描述
渥曼青霉素(Wortmannin),分离自丝状真菌-绳状青霉(Penicillium funiculosum),是一种有效、不可逆且特异的磷脂酰肌醇3-激酶(PI3K)抑制剂(IC50=2~4nM)。具有良好的细胞膜渗透性,与PI3K的催化亚基结合,进而抑制酶的体内外活性。也能阻断自吞噬形成,有效抑制Polo样激酶1(PLK1)(IC50=5.8nM)。
在成纤维细胞中,渥曼青霉素废止PDGF介导的肌醇(3,4,5)P3的生成(IC50=5nM)。在豚鼠中性粒细胞中,抑制fMLP诱导的PIP3和超氧阴离子生成(IC50=50nM),以及磷脂酶D激活。在NGF处理的PC12细胞中,阻断轴突延伸。在大鼠嗜碱粒细胞性白血病细胞(RBL-2H3)中抑制IgE介导的组胺分泌。渥曼青霉素在更高的浓度下能抑制其他激酶,比如肌球蛋白轻链激酶MLCK(IC50=200 nM)和血小板活化因子诱导的MAP激酶活化(IC50=200~300nM)。
我司提供两种形式的渥曼青霉素(Wortmannin),一种以溶于DMSO的储存液形式提供,浓度为25mM,使用更方便;一种以冻干粉的形式提供,更经济实惠;

文献1,Ng SS et al. Wortmannin inhibits pkb/akt phosphorylation and promotes gemcitabine antitumor activity in orthotopic human pancreatic cancer xenografts in immunodeficient mice. Clin Cancer Res. 2001 Oct;7(10):3269-75. MKBio PMID: 11595724
体内研究(动物模型):
动物模型(Animal Model):Tumor-bearing SCID mice (both s.c. and orthotopically implanted with human pancreatic adenocarcinoma cells PK1)
药物配制(Preparation):Wortmannin was dissolved at 0.4 mg/ml in DMSO, and diluted with 0.9% NaCl before use.
实验方法(Assay):A) In the first set of experiments, groups of tumor-bearing SCID mice (n = 4 each) were given single bolus injections of 0.7 mg/kg wortmannin via the tail vein and killed at various time points. B) In a second series of experiments, groups of animals (n = 4 each) were injected i.v. with increasing doses of wortmannin (0.175, 0.35, and 0.7 mg/kg) and killed at 4 h. C) In a third series of experiments, tumor-bearing SCID mice were randomly assigned to four groups (n = 4 each). Each group was given i.v. bolus injections of either the drug vehicle (≤1% DMSO), 80 mg/kg of gemcitabine for 48 h, 0.7 mg/kg of wortmannin for 4 h, or 80 mg/kg of gemcitabine for 48 h and then 0.7 mg/kg wortmannin for 4 h.

体外研究(细胞实验):
动物模型(Animal Model):Hepatocytes from Wistar rats
药物配制(Preparation):Wortmannin was dissolved in DMSO at 2mM, and stored at -20℃ in the dark. Dilutions in 0.9% NaCl were prepared just before the start of each experiment. The final DMSO concentration in the incubation medium did not exceed 0.25 % (by vol.). This concentration of DMSO did not affect the processes that were tested.
实验方法(Assay):Electron micrographs of isolated rat hepatocytes that were incubated for 60 min (5 mg dry cells/ml) with 50μM vinblastin alone (A, B) or in the presence of 50μM vinblastin plus 100 nM wortmannin.
结果(Results):Autophagosomes could hardly be detected in cells that were incubated in the presence of 100 nM wortmannin (Fig. 3 C) compared to cells incubated under maximal autophagic conditions (Fig. 3 A and B).
