Dermaseptin TFA 产品活性：Dermaseptin TFA 是从青蛙皮肤中分离出来的一种肽，在微摩尔浓度下表现出对细菌、真菌和原生动物强有力的抗菌 (antimicrobial) 活性。 产品来源： https://www.medchemexpress.cn/dermaseptin-tfa.html 研究领域：Anti-infection 作用靶点：Bacterial | Fungal In Vitro: Dermaseptin TFA is a water-soluble, thermostable, and nonhemolytic peptide endowed with highly potent antimicrobial activity against pathogenic fungi at micromolar concentration. Circular dichroism spectra of Dermaseptin TFA in hydrophobic media indicated 80% alpha-helical conformation, and predictions of secondary structure suggested that Dermaseptin TFA can be configured as an amphiphatic alpha-helix spanning over residues 1-27, a structure that perturbs membrane functions regulating water flux. Dermaseptin TFA exerts a lytic action upon bacteria, protozoa, yeasts, and filamentous fungi at micromolar concentrations. Molecular elements responsible for the exceptional antimicrobial potency of Dermaseptin TFA are to be traced to the NH2-terminal alpha-helical amphipathic segment spanning residues 1-18 of the molecule. Dermaseptin TFA (5-100 μg/ml; 48 hours) inhibits by 100% the proliferation of most microorganisms tested, including Gram-positive or Gram-negative bacteria, parasites, yeasts, and filamentous fungi, at micromolar concentrations. Dermaseptin TFA (5-100 μg/ml; 48 hours) does not inhibit the proliferation of human KJ3 cells after a 48 h incubation, and Dermaseptin TFA treatment for 1 h does not permeate guinea pig lymphocytes up to the highest concentration assayed (200 μg/ml). Hemolysis of rabbit erythrocytes occurrs after 1 h of treatment at doses above 200 μg/ml, with 50% hemolysis at 350 μg/ml. Dermaseptin TFA has antimicrobial activities and is against Aeromonas cauiae, Pseudomonas aeroginusa, Escherichia coli, Enterococcus faecalis, L. mezicana (NF α strain) and Microsporum canis (IP1194) with MIC values of 50 μg/ml; 100 μg/ml; 25 μg/ml; 15 μg/ml; and 50 μg/ml, respectively. 相关产品：Bioactive Compound Library Plus | Peptide Library | 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。
