基本信息
什么是埃替非巴肽？
埃替非巴肽（Integrilin，Millennium Pharmaceuticals，也由Schering-Plough / Essex共同推广）是糖蛋白IIb / IIIa抑制剂类的抗血小板药物。'Eptifibatide是一种衍生自在毒液中发现的蛋白质的环状七肽东南侏儒响尾蛇（Sistrurus miliarius barbouri）。它属于所谓的精氨酸 - 甘氨酸 - 天冬氨酸仿真模型，并可逆地结合血小板。
器具
埃替非巴肽用于降低不稳定性心绞痛或非ST段抬高患者（如非Q波）心肌梗死患者的急性心肌缺血事件（死亡和/或心肌梗塞）的风险（即非ST段） （冠状动脉介入治疗） - 接受非手术（保守）治疗的患者和接受经皮冠状动脉介入治疗（PCI）的患者。
该药物通常与阿司匹林或氯吡格雷和（低分子量或未分级）肝素一起使用。另外，应按照指示使用由硝酸盐，β-阻断剂，阿片类镇痛药和/或苯二氮卓类药物应用组成的通常的支持治疗。在开始使用埃替非巴肽治疗之前，血管造影评估和其他强化诊断程序可能被认为是第一线任务。
什么是肽？
肽是通过肽（酰胺）键桥接的氨基酸单体的生物学显示短链。
当一个氨基酸的羧基家族与另一个氨基酸的胺族一起进行时，构建共价化学键。最短的肽是二肽，包含通过单个肽键连接的2个氨基酸，然后是三肽，四肽等。多肽是长的，一致的和无支链的肽链。因此，肽属于生物低聚物和聚合物的广泛化学系列，以及核酸，寡糖和多糖等。
肽基于大小从蛋白质中分离出来，并且任意基准可被理解为具有约50个或更少的氨基酸。蛋白质由以生物功能方式组织的一种或多种多肽组成，通常与配体例如辅酶和辅因子结合，或与另一种蛋白质或其他大分子（DNA，RNA等）结合，或复杂的大分子组装。最后，尽管用于肽与多肽和蛋白质潜水员（例如，电泳，色谱等的特异性）的实验室技术的各个方面，区分肽与多肽和蛋白质的大小边界不是绝对的：长肽如淀粉样β已经被称为蛋白质，较小的蛋白质如胰岛素被认为是肽。
由于在形成每个酰胺键期间释放水分子时，由于从胺末端释放氢离子或从羧基末端释放羟基离子或两者，所以已掺入肽中的氨基酸被称为“残基” 。除肽之外的所有肽在肽末端具有N-末端和C末端杂质（如图中四肽所示）。图片）。
肽鉴定
肽根据以下的生产方法与几种身份分离：
牛奶多肽
当消化酶破裂时，乳蛋白酪蛋白形成两种天然出现的乳肽;它们也可以在牛奶发酵期间由乳杆菌形成的蛋白酶生长。
核糖体多肽
通过mRNA的翻译形成核糖体肽。它们通常经历蛋白水解以产生成熟的形式。这些功能通常在高等生物体中作为激素和信号分子。一些生物体产生肽作为抗生素，如微生物。由于它们被解释，所连接的氨基酸残基被阻止到由核糖体使用的氨基酸残基。
然而，这些肽通常具有翻译后修饰，例如磷酸化，羟基化，磺化，棕榈酰化，糖基化和二硫键形成。一般来说，它们是线性的，虽然已经观察到了套索结构。确实发生更奇特的操作，例如鸭嘴兽毒液中L-氨基酸与D-氨基酸的外消旋化。
非核糖体多肽
非核糖体肽通过对每个肽而不是由核糖体特异的酶组装。最常见的非核糖体肽是谷胱甘肽，其是大多数需氧生物的抗氧化防御的组分。其他非核糖体肽在单细胞生物，植物和真菌中最常见，并且由称为非核糖体肽合成酶的模块化酶复合物合成。
这些并发症通常以类似的方式布置，并且它们可以覆盖许多不同的模块以对显影产品执行各种化学操作。这些肽通常是环状的，并且可以具有高度复杂的环状结构，尽管线性非核糖体肽也是常见的。由于系统与建立脂肪酸和聚酮化合物的机械密切相关，常常会发现杂化化合物。恶唑或噻唑的存在通常表明该化合物是以这种方式合成的。
蛋白胨
另见Tryptone
Peptones是从动物乳或蛋白水解消化的肉中提取出来的。除了含有小肽之外，所得到的喷雾干燥材料需要“澄清”包括脂肪，金属，盐，维生素和许多其他生物化合物。 Peptones应用于培养细菌和真菌的营养培养基上。
肽片段
肽片段是指应用于鉴定或定量来源蛋白质的蛋白质片段。通常这些是在实验室中在受控样品上进行的酶降解的产物，但也可以是由自然效应降解的法医或古生物样品。
体育应用
术语肽已用于体育兴奋剂中的促分泌肽和肽激素：促分泌肽在世界反兴奋剂机构（WADA）禁用名录中被区分为附表2（S2）限制物质，因此被限制使用专业运动员进出竞争。自2008年以来，这种促分泌素多肽已被列入世界反兴奋剂机构禁用物质清单。澳大利亚犯罪委员会引用了澳大利亚体育运动中滥用促分泌素肽，包括生长激素释放肽CJC-1295，GHRP-6和GHSR（基因）hexarelin。关于在运动中使用促分泌素肽的合法性存在持续的争论。

Basic Information
What is Eptifibatide?
Eptifibatide (Integrilin, Millennium Pharmaceuticals, also co-promoted by Schering-Plough/Essex), is an antiplatelet drug of the glycoprotein IIb/IIIa inhibitor class.[1] Eptifibatide is a cyclic heptapeptide derived from a protein found in the venom of the southeastern pygmy rattlesnake (Sistrurus miliarius barbouri). It belongs to the class of the so-called arginin-glycin-aspartat-mimetics and reversibly binds to platelets.
Appliance
Eptifibatide is used to reduce the risk of acute cardiac ischemic events (death and/or myocardial infarction) in patients with unstable angina or non-ST-segment-elevation (e.g., non-Q-wave) myocardial infarction (i.e., non-ST-segment elevation acute coronary syndromes) both in patients who are to receive non surgery (conservative) medical treatment and those undergoing percutaneous coronary intervention (PCI).
The drug is usually applied together with aspirin or clopidogrel and (low molecular weight or unfractionated) heparin. Additionally, the usual supportive treatment consisting of applications of nitrates, beta-blockers, opioid analgesics and/or benzodiazepines should be employed as indicated. Angiographic evaluation and other intensive diagnostic procedures may be considered a first line task before initiating therapy with eptifibatide.
What are Peptides?
Peptides are biologically appearing short chains of amino acid monomers bridged by peptide (amide) bonds.
The covalent chemical bonds are constructed when the carboxyl family of one amino acid performs with the amine family of another. The shortest peptides are dipeptides, inculding 2 amino acids joined by a single peptide bond, followed by tripeptides, tetrapeptides, etc. Polypeptides are long, consistent, and unbranched peptide chains. Thus, peptides fall under the broad chemical series of biological oligomers and polymers, along with nucleic acids, oligosaccharides and polysaccharides, etc.
Peptides are diffrentiated from proteins on the basis of size, and as an arbitrary benchmark can be understood to have approximately 50 or fewer amino acids. Proteins consist of one or more polypeptides organized in a biologically functional way, often bound to ligands such as coenzymes and cofactors, or to another protein or other macromolecule (DNA, RNA, etc.), or to complicated macromolecular assemblies. Finally, while aspects of the lab techniques utilized to peptides versus polypeptides and proteins divers (e.g., the specifics of electrophoresis, chromatography, etc.), the size boundaries that distinguish peptides from polypeptides and proteins are not absolute: long peptides such as amyloid beta have been referred to as proteins, and smaller proteins like insulin have been regarded as peptides.
Amino acids that have been incorporated into peptides are called 'residues' due to the release of either a hydrogen ion from the amine end or a hydroxyl ion from the carboxyl end, or both, as a water molecule is released during formation of each amide bond. All peptides except cyclic peptides have an N-terminal and C-terminal impurity at the end of the peptide (as shown for the tetrapeptide in the image). the image).
Peptide Identification
Peptides are seperated from several identities, depending on the production method as following:
Milk Peptides
Two naturally appearing milk peptides are shaped from the milk protein casein when digestive enzymes break this down; they can also grow from the proteinases formed by lactobacilli during the fermentation of milk.
Ribosomal Peptides
Ribosomal peptides are formed by translation of mRNA. They are often subjected to proteolysis to create the mature form. These function, typically in higher organisms, as hormones and signaling molecules. Some organisms produce peptides as antibiotics, such as microcins. Since they are interpreted, the amino acid residues joined are prevented to those utilized by the ribosome.
However, these peptides frequently have posttranslational modifications... such as phosphorylation, hydroxylation, sulfonation, palmitoylation, glycosylation and disulfide formation. Generally, they are linear, although lariat structures have been observed. More exotic manipulations do occur, such as racemization of L-amino acids to D-amino acids in platypus venom.
Nonribosomal Peptides
Nonribosomal peptides are assembled by enzymes that are specific to each peptide, rather than by the ribosome. The most common non-ribosomal peptide is glutathione, which is a component of the antioxidant defenses of most aerobic organisms. Other nonribosomal peptides are most common in unicellular organisms, plants, and fungi and are synthesized by modular enzyme complexes called nonribosomal peptide synthetases.
These complications are often laid out in a similar fashion, and they can cover many different modules to perform a various set of chemical manipulations on the developing product. These peptides are often cyclic and can have highly complex cyclic structures, although linear nonribosomal peptides are also common. Since the system is closely related to the machinery for building fatty acids and polyketides, hybrid compounds are often found. The presence of oxazoles or thiazoles often indicates that the compound was synthesized in this fashion.
Peptones
See also Tryptone
Peptones are extracted from animal milk or meat digested by proteolysis. In addition to containing small peptides, the resulting spray-dried material [clarification needed] includes fats, metals, salts, vitamins and many other biological compounds. Peptones are applied on nutrient media for growing bacteria and fungi.
Peptide Fragments
Peptide fragments refer to fragments of proteins that are applied to identify or quantify the source protein. Usually these are the products of enzymatic degradation performed in the laboratory on a controlled sample, but can also be forensic or paleontological samples that have been degraded by natural effects.
Applications in Sports
The term peptide has been applied to mean secretagogue peptides and peptide hormones in sports doping matters: secretagogue peptides are distinguished as Schedule 2 (S2) stricted substances on the World Anti-Doping Agency (WADA) Prohibited List, and are therefore stricted for use by professional athletes both in and out of competition. Such secretagogue peptides have been on the WADA prohibited substances list since at least 2008. The Australian Crime Commission cited the alleged misuse of secretagogue peptides in Australian sport including growth hormone releasing peptides CJC-1295, GHRP-6, and GHSR (gene) hexarelin. There is ongoing argument on the legality of utilizing secretagogue peptides in sports.
