Proanthocyanidins 产品活性：Proanthocyanidin (Procyanidin) 是一类在高等植物中广泛分布的多酚化合物，由亲电子黄烷酰基单元组成。Proanthocyanidin 可用作抗氧化剂和抗癌剂。Proanthocyanidin 还显示出抗炎，保护心脏，抗菌和抗真菌的特性，可用于研究慢性静脉功能不全、毛细血管脆弱、晒伤和视网膜病变。 产品来源： https://www.medchemexpress.cn/Proanthocyanidins.html 研究领域：Anti-infection 作用靶点：Bacterial | Fungal 来源：植物 | 其他科 结构分类：黄酮类 | 双黄酮 | 酚类 | 多酚类 | 结构分类 In Vitro: Proanthocyanidin are present in plants as complex mixtures of polymers. Predominant food sources are red wine, tea, chocolate and fruits like grapes, apples, pears, and cranberries.? The most interesting antibacterial activity of Proanthocyanidin is related to their presence in cranberries (Vaccinium macrocarpon Ait.). A number of clinical trials have demonstrated the effectiveness of cranberry consumption in preventing urinary tract infections (UTIs). Although UTIs can be caused by many microorganisms, more than 85% are caused by Escherichia coli. The presence of P-fimbriae on E. coli, which are proteinaceous fibers on the bacterial cell wall, has been clearly established as a virulence factor, since they are responsible by producing adhesions for adherence to uroepithelial cells. Recently, it is demonstrated that cranberry Proanthocyanidin might inhibit P-fimbriated E. coli from adhering to uroepithelial cells. The antiadhesion activity of cranberry juice appears to be related to the presence of Proanthocyanidin with at least one A-type linkage. In Vivo: The effects of cacao liquor Proanthocyanidin on 2- amino-1-methyl-6-phenylimidazo [4,5-b] pyridine-induced mutagenesis in vivo carcinogenesis in female Sprague-Dawley rats are investigated. In the Ames assay, Proanthocyanidin shows strong antimutagenic effects when assayed in the presence of S-9 mixture. They also inhibit significantly rat pancreatic carcinogenesis in the initiation stage, but not mammary carcinogenesis. 相关产品：Natural Product Library Plus | Drug Repurposing Compound Library Plus | Clinical Compound Library Plus | Bioactive Compound Library Plus | Rapamycin | Ferrostatin-1 | Cycloheximide | Doxorubicin hydrochloride | Bafilomycin A1 | Dimethyl sulfoxide | Dexamethasone | Puromycin dihydrochloride | Staurosporine | Actinomycin D | Etoposide | G-418 disulfate | Nigericin sodium salt | 5-Azacytidine | Brefeldin A | CCCP | Estradiol | Ionomycin | Hygromycin B | Mitomycin C | Resveratrol | Tunicamycin | Everolimus | Doxycycline hyclate | Tacrolimus | Oligomycin | Methotrexate | Streptozotocin | Lactate sodium 品牌介绍: MCE (MedChemExpress) 拥有数百种全球独家化合物，我们致力于为全球科研客户提供最新最全的高品质小分子活性化合物；10,000 多种高选择性抑制剂、激动剂涉及各热门信号通路及疾病领域；设有专业的实验中心和严格的质控、验证体系；提供 LC/MS、NMR、HPLC、手性分析、元素分析等各项质检报告，确保产品的高纯度、高品质；产品的生物活性多经各国客户实验验证；Nature, Cell, Science 等多种顶级期刊及制药专利收录了MCE客户的科研成果；专业团队跟踪最新的制药及生命科学研究进展，为您提供全球最新的活性化合物；与世界各大制药公司及知名科研机构建立了长期的合作。
