药学英语一、Physiology and Pathology（P9）生理学与病理学（一）概念1、Physiology is the scientific study of function in living systems.（ppt）the study of how living organisms work.(书里)2、Pathology is a significant component of the causal study of disease and a major field in modern medical practice and diagnosis.(ppt)the science of disease,which deal with the studies of etiology, pathogenesis, morphologic structures, changes in functions and metabolism in the living organisms by means of natural science.(书里) 3、Pathophysiology is the study of functional changes in the body which occur in response to disease or injury.a convergence of Pathology with Physiology4、etiology is the study of causation,or the origination of diseases.5、the pathogenesis of a disease is the mechanism that causes the disease.6、inflammation is a response of body tissues to injury or irritation; (刺激）characterized by pain and swelling and redness and heat. （红热胀痛）(二)思考题1.How do you understand pathology and pathophysiology?Pathology is the science of diseasePathophysiology is the study of functional changes in the body which occur in response to disease or injury.2. what is the difference between etiology and pathogenesis?Etiology is the study of causation, or the origination of diseases.the pathogenesis of a disease is the mechanism that causes the disease 3. Could you explain the symptoms and signs of a disease?symptoms of a disease(“症”): as certain biologic processes are encroached on(侵害) ,the patient begins to feel subjectively that something is wrong., These subjective feelings are called symptoms of disease.Symptoms are subjective and can be reported only by the patient to an observer.signs of a disease（“征”）：when manifestations of the disease can be objectively identified by an observer, these are terms signs of the disease.4、what is the pathogenesis of tuberculosis?the pathogenesis of tuberculosis would include the mechanisms whereby the invasion of the body by tubercle bacillus ultimately leads to the observed abnormalitiesBiochemistry is the study of chemical processes in living organisms.二、Medicinal Chemistry药物化学(一)概念1、Medicinal chemistry(药物化学)is the science that deal with the discovery or design of new therapeutic chemicals and the development of these chemicals into useful medicine.2、Medicine（药品drug, pharmaceutics) is a compound that interacts with a biological system, and produces a biological response (ideally desired and positive)3、Therapeutic index（治疗指数）sure of the ratio of undesirable to desirable drug effects. Therapeutic index=LD50/ED50The larger the Therapeutic index, the greater the margin of safety of drug!4、LD50（半数致死量）:the lethal dose for 50% of the test animals5、ED50（半数有效量）:the effective dose that produces the maximum therapeutic effect in 50% of the test animals.6、Log P（脂水分配系数）is the base-ten logarithm of the partition coefficients (分配系数)7、Chirality（手征性）: a molecule is considered chiral if there exists another molecule that is of identical composition ,but which is arranged in a non-superposable mirror image.8、Bioisosteres(生物电子等排体): are substituents or groups that havechemical or physical similarities ,and which produce broadly similar biological properties.9、Bioisosterism(生物电子等排性) is a lead modification approach that has been shown to be useful to attenuate toxicity （降低毒性）,modify the activity of a lead （修饰活性）and may have a significant role in the alteration of metabolism of the lead.10、Prodrug（前药）is drug which is given (taken) in an inactive form. Once administered ,the prodrug is metabolized by the body into the biologically active compound.（二）知识点1、The difference of “good” and “bad” drugs:Depend on dosage and chronic exposure. and therapeutic index can be the measure of safety of drugs2、classification of drugsFour main groups:（1）B y biological effect---varied assortment of drugsanalgesics（止痛剂）,anti-asthmatics（平喘药）,antipsychotics（抗精神病药）etc.（2）B y chemical structure---common skeletonPenicillin （青霉素类）,opiates(阿片类药物) etc.（3）B y target system（靶向系统）----affect a target system(synthesis, release, receptor)antihistamine (抗组胺药)etc.（4）B y target site of action(作用靶点)—target enzyme or receptor Anti-cholinesterase (抗胆碱酯酶)3、Medicinal chemistry involves:(1)synthesis (2)structure-activity relationships(SAR)(3)receptor interactions(4)absorption, distribution, metabolism and excretion (ADME)4、Medicinal chemistry cover 3 critical steps:● A discovery step●An optimization step● A development step5、important functional groups on drugs:(1)Alkanes&alkenes(烷烃和烯烃) (2)alcohol 醇（3）phenols 酚（4）ethers 醚（5）aromatic hydrocarbons 芳香化合物6、a drug usually has 3 names:（1）chemical (化学名)Mostly following rules by chemical abstracts service(CAS)One compound can only have one name（2）international non-proprietary names(INN,通用名)Convenient to remember ,needed when apply for registration, cannot be trade marked（商标）or patented(取得专利权)One compound can only have one name（3）commercial (商品名)Named by manufactures ,can be trade marked to protect the brand. One compound can have many different names7、prodrug strategies are used to overcome a variety of problems by:(1)Altering solubility 改变溶解度(2)Improving membrane permeability 提高细胞膜通透性(3)Slow release of the active agent 缓慢释放活性(4)Masking drug toxicity or side effects 掩蔽药物毒副作用三、Phytochemistry and Natural Products 天然药物化学和天然产物(一)概念1、Phytochemistry（天然药物化学）is in the strict sense of the study of phytochemicals, which are derived from plants. In a narrower sense the terms are often used to describe the large number of secondary metabolic compounds found in plants.2、Primary metabolites(初级代谢产物): compounds that are common to many types of organisms, that fulfill basic biologicalfunctions(e.g.respiration 呼吸,photosynthesis光合作用,DNA replication ＤＮＡ复制)3、Secondary metabolites（次级代谢产物）：compounds that are not essential to daily ,common metabolism of cells and individual organisms. Instead, these compounds are unique to certain taxa and fulfill secondary functions ,often involved in signaling between organisms (e.g.mate recognition配偶识别, chemical defense化学防御, chemotaxis 趋化作用)4、natural products: a natural product is a chemical compound or substance produced by a living organism found in nature.（Primary metabolites & Secondary metabolites）（二）知识点1、summary:●natural products are compounds synthesized by living organisms,usually organic molecules with 5-100 carbons●natural products can be primary or secondary metabolites●secondary metabolites are produced via enzymatic pathways fromprimary metabolic building-blocks2、how to get natural products?/the process to purify natural products?(1)Plant collection植物采集(2)Extraction萃取(3)Fractionation分馏(4)Isolation分离(5)Structural determination 结构测定（UV，IR，MS,NMR）3、Journals in Phytochemistry and Natural Products Chemistry:●Journal of Natural Products 天然产物杂志●Phytochemistry●Journal of Ethnopharmacology 民族药物学杂志●Planta Medica 天然药物学会志（欧洲）●Phytochemical Analysis 植物化学分析●Chemical &Pharmaceutical Bulletin 化学与药学通报（日本）Review journals 综述期刊●Natural Product Reports 天然产物报告●Phytochemistry Review四、biochemistry 生物化学1、What is the goal of biochemistry？The basic goal of the science of biochemistry is to determine how the collections of inanimate molecules （无生命的分子）that constitute living organisms interact with each other to maintain and perpetuate life.（延长生命）2、Macromolecules（生物大分子）that constitute living organisms include proteins, nucleic acid (DNA and RNA), and polysaccharides.3、20种氨基酸：1、丙氨酸Alanine/Ala/A2、半胱氨酸Cysteine/Cys/C3、天冬氨酸Asparticacid/ Asp /D4、谷氨酸Glutamic acid/Glu/E5、苯基丙氨酸Phenylalanine/Phe/F6、甘氨酸glycine/Gly/G7、组氨酸Histidine/His/H 8、异亮氨酸Isoleucine/Ile/I9、赖氨酸Lysine/Lys/K 10、亮氨酸Leucine/leu/L11、蛋氨酸Methionine/Met/M 12、天冬酰胺Asparagine/Asn/N 13、脯氨酸Procine/pro/P 14、谷氨酰胺Glutamine/Gln/Q 15、精氨酸Arginine/Arg/R 16、丝氨酸Serine/Ser/S17、苏氨酸Threonine/Thr/T 18、缬氨酸Valine/Val/V19、色氨酸Tryptophan/Try/W 20、酪氨酸Tyrosine/Tyr/Y五、Microbiology 微生物学1、Microbiology is the study of microscopic organisms such as bacteria, fungi, protozoa,virus and some types of algae, which encompass various sub-disciplines including virology, mycology, parasitology, bacteriology, and other branches.2、几位科学家的成就Bacteriology was found in the 19th century by Ferdinand CohnCohn was also the first to formulate the scheme for the taxonomic classification of bacterial and discover spores费迪南德∙科恩, Ferdinand Cohn德国博物学家和植物学家，以研究藻类、细菌和蕈类著称，被视为细菌学的创始者之一。
