Searching for reaction in organic synthesis has been made much easier in the current age of computer databases. However, the dilemma now is which procedure one selects among the ocean of choices. Especially for novices in the laboratory, it becomes a daunting task to decide what reaction conditions to experiment with first in order to have the best chance of success. This collection intends to serve as an "older and wiser lab-mate" one could have by compiling many of the most commonly used experimental procedures in organic synthesis. With chapters that cover such topics as functional group manipulations, oxidation, reduction, and carbon-carbon bond formation, Modern Organic Synthesis in the Laboratory will be useful for both graduate students and professors in organic chemistry and medicinal chemists in the pharmaceutical and agrochemical industries.

The stories behind drug discovery are fascinating, full of human and scientific interest. This is a book on the history of drug discovery that highlights the intellectual splendor of discoverers as well as the human frailty associated with them. History is replete with examples of breakthrough medicines that have saved millions of lives. Ether as an anesthetic by Morton; penicillin as an antibiotic by Fleming; and insulin as an anti-diabetic by Banting are just a few examples. The discoverers of these medicines are doubtlessly benefactors to mankind - for instance, without penicillin, 75% of us probably would not be alive because some of our parents or grandparents would have succumbed to infections.Dr. Jack Li, a medicinal chemist who is intimately involved with drug discovery, has assembled an astounding amount of facts and information behind important drugs through extensive literature research and interviews with many inventors of the drugs including Viagra and Lipitor. There have been many myths and inaccuracies associated with those legendary drugs. The inventors perspectives afforded this book an invaluable accuracy and insight because history is not history unless it is true.The text is supplemented by many anecdotes, pictures and postage stamps. Both specialist and layman will find Laughing Gas, Viagra, and Lipitor informative and entertaining. Students in chemistry, pharmacy, and medicine, workers in healthcare and high school science teachers will find this book most useful.

Over 25 million people in the U.S. alone have benefited from statins--such drugs as Lipitor, Zocor, Crestor, Pravachol, and other cholesterol-lowering medicines--in preventing stroke, heart attack, and other forms of coronary heart disease. But how did these remarkable, life-saving drugs come into being? In Triumph of the Heart, Dr. Jie Jack Li, a medicinal chemist and expert on drug discovery, tells for the first time the fascinating story of statins. Drawn from interviews with many scientists involved in the discovery and development of these drugs, the book illuminates the human side of science by revealing the role played by persistence, luck, and sudden insight that characterize major discoveries. For scientists in the drug industry, health care professionals, students of medicine, and all those intrigued by the basic human drive to explore and discover, Triumph of the Heart offers a compelling view of one of the most important drug discoveries of our time.

It's time to examine the human history of viruses, vaccines, and antiviral drugs...Public response to the COVID-19 pandemic has demonstrated that misinformation about viruses is widespread. Vaccine skepticism is rampant, and many people have been quick to accept bogus claims unsupported by science. In his latest book, Jie Jack Li sets the record straight by revealing the science and history behind antiviral drugs. Conquest of Invisible Enemies: A Human History of Antiviral Drugs guides readers through the history of viruses, vaccinations, and treatments. Readers learn about the discovery of viruses and diseases, such as HIV/AIDS, hepatitis, influenza, and SARS-CoV-2 (COVID-19). The first chapter takes an expansive look at how viruses have shaped human history. Subsequent chapters narrow in on specific viruses, diseases, and drug treatments. For example, chapter four, on influenza, looks at the 1918 Spanish flu pandemic, the history of vaccination efforts, and influenza drugs and vaccines today. Chapter five, on coronaviruses, considers drug treatments for SARS, MERS, and SARS-CoV-2. It also discusses the development of COVID-19 vaccines and drugs. Conquest of Invisible Enemies: A Human History of Antiviral Drugs focuses on the human drama behind drug discovery. Written in an engaging and accessible style, Li's timely book dispels common misconceptions about viruses and treatments and places the COVID-19 pandemic in historical context.

Drugs like Lipitor, Plavix, Taxol, and Zoloft are integral in today's medicinal world. These widely used products save lives and improve the quality of lives, playing a crucial role in everything from cholesterol management to cancer treatment. These advances in medicine were brought into existence after nuanced process of creation, featuring a wide range of chemical and pharmacological experimentation and discovery.Top Drugs: Their History, Pharmacology, and Synthesis provides an in-depth study on ten prominent drugs, outlining the chemistry behind each one's creation. Jie Jack Li, a medicinal chemist and an expert on drug discovery, offers a thorough analysis of the landscape of current drug development. The comprehensive text is divided by health issues, including cardiovascular, cancer, metabolic diseases, and infectious diseases. Each section features individual chapters on significant drugs, outlining the chemistry and history of the drug's discovery. Li begins each chapter with the product's history, providing necessary context. Li then proceeds to describe the mechanism of action, structure-activity relationship (SAR), bioavailability, metabolism, toxicology, the discovery route, and the process route. Top Drugs: Their History, Pharmacology, and Synthesis will acclimate students, scientists, and interested laypersons to the world of chemistry and drug discovery.

Blockbuster drugs-each of which generates more than a billion dollars a year in revenue-have revolutionized the industry since the early 1980s, when sales of Tagamet alone transformed a minor Philadelphia-based firm into the world's ninth-largest pharmaceutical company. In Blockbuster Drugs, Jie Jack Li tells the fascinating stories behind the discovery and development of these highly lucrative medicines, while also exploring the tumult the industry now faces as the "patent cliff" nears. Having spent most of his career in drug research and development, Li brings an insider's eye to the narrative as he recounts the tales of discovery behind such drugs as Tagamet, Zantac, Claritin, Prilosec, Nexium, Serouquel, Plavix, and Ambien. As he discusses each breakthrough, Li also shows that scientific research is filled with human drama-serendipitous discoveries, sudden insights, tense confrontations. For instance, the author tells of James Black, who persisted in the research that led to Tagamet-and that would ultimately win him a Nobel Prize-despite pressure from top executives to pursue "more profitable" work. The book shows how research behind Prilosec combined creativity, international cooperation, and luck-the turning point being a chance encounter of American and Swedish scientists at a conference in Uppsala. There are also tales of fabulous rewards--George Rieveschl, the chemist who invented Benadryl, made a fortune on royalties-and of unjust desserts. Finally, Li shows that for the world's largest prescription drug manufacturers, recent years have been harrowing, as many popular drugs have come off patent in the U.S. market, meaning hundreds of billions of dollars in lost revenue. Anyone who enjoys tales of scientific discovery, or is curious about the history behind the prescriptions they take, or wants a revealing inside look at the pharmaceutical industry will find this book well worth reading.
