Unit 1 Production of DrugsAbout 5000 antibiotics have already been isolated from microorganisms，but of these only somewhat fewer than 100 are in therapeutic use. It must be remembered，however，that many derivatives have been modified by partial synthesis for therapeutic use;some 50，000 agents have been semisynthetically obtained from户lactams alone in the last decade. Fermentations are carried out in stainless steel fermentors with volumes up to 400 m3. To avoid contamination of the microorganisms with phages etc. the whole process has to be performed under sterile conditions. Since the more important fermentations occur exclusively under aerobic conditions a good supply of oxygen or air(sterile)is needed. Carbon dioxide sources include carbohydrates，e. g. molasses，saccharides，and glucose. Additionally the microorganisms must be supplied in the growth medium with nitrogen-containing compounds such as ammonium sulfate，ammonia，or urea，as well as with inorganic phosphates. Furthermore，constant optimal pH and temperature are required. In the case of penicillin G，the fermentation is finished after 200 hours，and the cell mass is separated by filtration. The desired active agents are isolated from the filtrate by absorption or extraction processes. The cell mass，if not the desired product，can be further used as an animal feedstuff owing to its high protein content.关于5000抗生素已经分离出的微生物，但其中只有不到100有些治疗使用。

PART 3 INDUSTRIAL PHARMACYUnit 11 Tablets (The Pharmaceutical Tablets Dosage Form)Role in TherapyThe oral route of drug administration is the most important method of administering drugs for systemic effects. Except in cases of Insulin therapy，the parenteral route is not routinely used for self-administration of medications. The topical route of administration has only recently been employed to deliver drugs to the body for systemic effects，with two classes of marketed products: Nitroglycerin硝酸甘油酯for the treatment of angina心绞痛and scopolamine莨菪胺for the treatment of motion sickness晕动病，指晕车、晕船等. Other drugs are certain to follow，but the topical route of administration is limited in its ability to allow effective drug absorption for systemic drug action. The parenteral route of administration is important in treating medical emergencies in which a subject is comatose昏迷的or cannot swallow，and in providing various types of maintenance therapy for hospitalized patients. Nevertheless，it is probable that at least 90 % of all drugs used to produce systemic effects are administered投药，给药by the oral route. When a new drug is discovered，one of the first questions a pharmaceutical company asks is whether or not drug can be effectively administered for its intended effect by the oral route. If it cannot，the drug is primarily relegated to被降级到administration in a hospital setting or physician's office. If patient self- administration cannot be achieved，the sales of the drug constitute only a small fraction of what the market would be otherwise. Of drugs that are administered orally，solid oral dosage forms represent the preferred class of product. The reasons for this preference are as follows. Tablets and capsules represent unit dosage forms in which one usual dose of the drug has been accurately placed. By comparison相比之下，liquid oral dosage forms，such as syrups，suspensions，emulsions，solutions，and elixirs，are usually designed to contain one dose of medication in 5 to 30 ml. The patient is then asked to measure his or her own medication using a teaspoon，第三部分工业药剂学第11单元药片(医药的片剂剂型)在治疗中的作用口服给药途径是通过给药获得全身作用效果中最重要的方法。

Unit 13 Sterile ProductsSterile ProductsSterile products are dosage forms of therapeutic agents that are free of viable microorganisms. Principally，these include parenteral，ophthalmic，irrigating preparations. Of these, and parenteral products are unique among dosage forms of drugs because they are injected through the skin or mucous membranes into internal body compartment. Thus，because they have circumvented the highly efficient first line of body defense，the skin and mucous membranes，they must be free from microbial contamination and from toxic components as well as possess an exceptionally high level of purity. All components and processes involved in the preparation of these products must be selected and designed to eliminate，as much as possible，contamination of all types，whether of physical，chemical，or microbiologic origin.Preparations for the eye, though not introduced into internal body cavities，are placed in contact with tissues that are very sensitive to contamination. Therefore，similar standards are required for ophthalmic preparations).Irrigating solutions are now also required to meet the same standards as parenteral solutions because during an irrigation procedure，substantial amounts of these solutions can enter the bloodstream directly through open blood vessels of wounds or abraded mucous membranes. Therefore，the characteristics and standards presented in this chapter for the production of large-volume parenteral solutions apply equally to irrigating solutions. Sterile products are most frequently solutions or suspensions，but may even be solid pellets for tissue implantation. The control of a process to minimize contamination for a small quantity of such a product can be achieved with relative ease. As the quantity of product increases，the problems of controlling the process to prevent contamination multiply. Therefore，the preparation of sterile products has become a highly specialized area in pharmaceutical processing.

《制药工程专业英语》Unit9,P96-98
所选译文位置：《制药工程专业英语》Unit9，P96-98外文文献原稿和译文原稿Throughout recorded history ，bacterial infections have periodically exacted heavy tolls on the human population .During “Black Death”bubonic plague episode of 1347-1351.Yersinia pestis killed an estimated 25 million in Asia and Europe .US PublicHeath Service statistics for 1910 and 1920 show that early in this century tuberculosis killed one in every 1000 US residents . Even today ,mainly in developing countries ,Mycobacterium tuberculosis remains the leading cause of death attributable to a single infectious agent, killing over three million people worldwide every year.Within just a few decades, the availability of an anti-infective pharmacopoeia suddenly provided humans with the potential to circumvent Nature's time-tested, live-or-die evolutionary paradigm for enhancing their survival prospects under constant microbial barrage. Those members that previously would have succumbed could now survive longer with the help of vaccines and antibiotics - auxiliary agents which work alongside the immune system to fight infection. In effect, humans' employment of these auxiliaries can be looked upon as exemplifying a self-contrived evolution in their immunological defense system.Once the usefulness of Sir Alexander Fleming's penicillin discovery had been demonstrated, a flurry of other antibiotics unearthed from natural sources followed. Some of these proved suitable for treating disease, usually after chemical modification to improve the natural compound's potency, safety or pharmacokinetic profiles.For most of the past 50 years, it seemed that medical science had gained a strong upper hand over bacterial disease. Some pharmaceutical houses and funding agencies decided to cut back on antibiotic discovery efforts, as it appeared that the physician's antibacterial arsenal was well stocked. But the nature of the diseases has proved otherwise.The rapid escalation in the incidence of multiple-antibiotic-resistant pathogens is now raising very serious concerns worldwide.This development underscores thepowerful evolutionary capabilities of bacterial populations under the selective pressure imposed by antibiotic therapy .Antibiotic resistance Resistance problems are seen with both Gram-negative(for example Escherichia coli) and Gram-positive bacteria (such as Staphylococcus aureus), but most of the concerns are with the latter group of pathogens.Streptococcus is a respiratory Gram-positive pathogen responsible for 40,000 deaths a year in the US alone. A rapidly rising prevalence of penicillin-resistant S. pneumoniae infections is now problematic in many countries. One of the worst situations is in Hungary, where 70%of the S. from children tested in 1988-1989 were resistant to penicillin.Bacteria have evolved numerous ploys for defeatng antibiotic action——they inactivate the antibiotic by hydrolysis, acylation , phosphorylation or nucleotidylation reactions; aitre the antibiotic’s target site; or reduce the intracellular drug concentration by decreasing membrane permeability and/or actively pumping the drug out of the cell . With improved understanding of these mechanisms of resistance through molecular biology and biochemical techniques, medicinal chenmists have been provided with the targets for attempting to circumvent some of the resistance problems.A predominant resistance mechanism against the B-lactam drugs (such as Penicillin) involves enzymatic cleavage of the B-lactam ring. While the drug Methicillin was developed because it could withstand such action, strains of Methicillin-resistance S.ayreus (MRSA) emerged in 1961 , jusr two years after the drug first went into wide use . MRSA strains evolved so that they had an additional drug-target protein involved with cell wall biosynthesis, and this altered protein has a very low affinity for virtually all B-lactams. To make matters worse, mose MRSA strains are also resistant to many other classes of antibiotics,with the exception of the glycopeptide Vancomycin. Now seen around the globe, MRSA strains are very problematic in Japan ( where in some hospitials 60% of S. Aureus isolates are MRSA ), as well as in Spain , France , Italy and the US , each with a greater than 30% incidence.A particularly disturbing milestone was the 1988 emergence of Vancomycin-resistant enterococci (VRE). Some VRE now don’t respond to any available antibiotics. The enterococci have become the second mose frequently encountered hospital acquired pathogne in the US, where the incidence of VRE strains is now about15% of all clinical enterococcal isolates . Resistance to Vancomycin arises because a D-alanine-D-lactate residue ( which vancomycin binds to only poorly) has been substituted for the D-alanine-D-alanine residue normally found at the rerminus of a pentapeptide precursor involved in the bacteria’s cell wall biosynthesis.There is now a great concern that the genes conferring resistance in VRE to glycopeptides like Vancomycin will be naturally transferred to S.aureus, has been experimentally demonstrated feasible by William Noble at St Thomas' Hospital, London. As Vancomycin is the drug of last resort for treating MRSA infections, the anticipated natural acquisition of Vancomycin resistance in this virulent pathogen would result in the sobering return to pre-antibiotic era therapeutic failures, should no alternate effective therapy become available.ConclusionsMan's use of antibiotics has rapidly accelerated the dynamic evolutionary interplay between humans and bacteria. The recent rapid rise in multidrug-resistant Gram-positive bacterial infections worldwide has sounded a loud claxon for the need of new, effective therapies. The newer agents described here may provide physicians with a refurbished arsenal.The discovery of new bacterial drug targets through genomic research, as well as improvements in our understanding of bacterial resistant mechanisms, hold promise for the discovery of new means of treating multidrug-resistant bacterial infections. Given enough time, bacteria will eventually be able to develop resistance to any new antibacterial agent. Those drugs that can attack the pathogen through a novel mechanism may have reduced propensities to rapid resistance development.译文纵观历史记载，细菌感染的人口定期付出沉重的收费。

P61 Unit 5 药物研发药物代谢作用和药代动力学药物代谢和制药学研究需要建立一套关于化合物代谢和方式的知识，化合物水平及其代谢产物根据药物给予量和施用时间长度变化的方式（决定）。
在早期药物临床发展临床阶段,很少有代谢数据权威性的管理要求。
然而，新陈代谢研究有助于解释毒理学结果和研究设计，以及有助于将动物安全性效率数据进行外插。
在生物学流体或组织中需要开发测定法测量药物和主要代谢产物水平。
目的是快速开发可重现性方法。
高效液相色谱通常用于分离，但其他技术如气相色谱在试用时也可以使用。
例如检测法可以是紫外光，荧光测定法，电化学方法，质谱法。
当化合物的活性很高时，体液和组织液中仅存痕量物质，检测可能出现问题。
放射免疫测定法可以提供更高的灵敏度，以及在给定时间内有可能分析出更多的化合物。
然而，放射免疫测定法有可能花很长时间来显影，并且缺少特异性将是一个问题。
需要关于化合物/代谢物血浆浓度的信息来支持毒理学研究，以及帮助选择剂量水平。
有最初需要建立药代动力学的线性区域，即其中剂量对AUC可被认为是一个线性的范围。
对非线性原因的确定例如代谢饱和的吸收/消除将有助于理解毒理学或药理学现象。
临床学一旦已经完成并分析充分的动物试验，药物公司将决定是否将药物投入人体研究阶段。
这一步通常包括公司专家，临床研究者和临床委员会的批准，并且在某些国家，例如在美国，还需要政府机构如FDA（美国食品和药品监督管理局）的审查。
当出资公司向FDA提出一种新药的调查申请时，这种新药就首先被FDA 审查。
FDA必须在30天内让出资者知道以他们的判断这个临床研究是否足够安全。
如果足够安全，实际上IND可考虑在其中并且临床可以继续进行。
如果不安全，FDA会将这个临床研究暂停直到他们的担忧成功解决。
规划这个临床方案时，很重要的是参考目标性质并且探究药物的潜在临床效益，尽可能早地参考这些，以便去除掉未能达到预期效果的候选药物。
新候选药物最初在人体内试用应遵循以下主要原则：确定药物在人体内的安全性和耐受性。

Over the last few years fermentation - i. e. microbiological processes has become extremely important. Through modern technology and results from genetic selection leading to the creation of high performance mutants of microorganisms，fermentation has already become the method of choice for a wide range of substances. Both Eukaryonts (yeasts and moulds)and Prokaryonts(single bacterial cells，and actinomycetes)are used microorganisms. The following product types can be obtained:
在过去的几年里发酵-岛大肠杆菌微生物过程变得极其重要。通过现代技术和基因选择的结果导致了突变体的微生物创造高性能，发酵，已成为首选方法各种各样的物质。这两个Eukaryonts（酵母菌和霉菌）和Prokaryonts（单细胞细菌，放线菌和）用于微生物。下列产品类型可以得到：
1。细胞的物质（单细胞蛋白），
e.g. 11-hydroxylation; also insulin, interferon, antibodies, peptide
hormones，enzymes，vaccines
Ⅱ.Natural products，and
Ⅲ .Products from partial syntheses (semi-synthetic products).
The emphasis of the present book is on the most important compounds of groups I and Ⅲ一thus Drug synthesis. This does not mean，however，that natural products or other agents are less important. They can serve as valuable lead structures，and they are frequently needed as starting materials or as intermediates for important synthetic products.
本书的重点是团体的最重要的化合物Ⅰ和Ⅲ一所以药物合成。这并不意味着，但是，天然产品或其他代理人并不太重要。它们可以作为有价值的领导结构，他们常常为原料，或作为重要的合成中间体产品的需要。

Several therapeutically significant natural products which were originally obtained from natural sources are today more effectively -i. e. more economically -prepared.. by total synthesis. Such examples include L-amino acids，Chloramphenicol，Caffeine, Dopamine， Epinephrine，Levodopa, peptide hormones，Prostaglandins，D-Penicillamine，Vincamine， and practically all vitamins.

3。主要降解产物（主要代谢物），
4。二级降解产物（次生代谢物）。
Disregarding the production of dextran from the mucous membranes of certain microorganisms，e. g. Leuconostoc mesenteroides，classes 2 and 3 are the relevant ones for the preparation of drugs. Dextran itself，with a molecular weight of 50,000 ~ 100,000，is used as a blood plasma substitute. Among the primary metabolites the L-amino acids from mutants of Corynebacterium glutamicum and Brevibacterium flavum are especially interesting. From these organisms some 350，000 tones of monosodium L-glutamate (food additive)and some 70，000 tones of L-lysine(supplement for vegetable proteins)are produced. Further important primary metabolites are the purina nucleotides，organic acids， lactic acid，citric acid，and vitamins，for example vitamin B,2 from Propionibacterium shermanii.
