Context paragraphs:
Robert Burns Woodward: Robert Burns Woodward (April 10, 1917 – July 8, 1979) was an American organic chemist.  He is considered by many to be the preeminent organic chemist of the twentieth century, having made many key contributions to the subject, especially in the synthesis of complex natural products and the determination of their molecular structure.  He also worked closely with Roald Hoffmann on theoretical studies of chemical reactions.  He was awarded the Nobel Prize in Chemistry in 1965.

Chester John Cavallito: Chester J. Cavallito (May 7, 1915 – March 28, 2010) was an American organic chemist.  He was particularly known for his work on the chemistry of garlic.  Beginning in 1944, with his colleagues, he reported on the isolation from crushed garlic, synthesis (from diallyl disulfide) and antibiotic activity of a compound he named allicin.  Cavallito established that allicin was a member of a class of organosulfur compounds known as thiosulfinates.  He also synthesized and reported on the chemical and biological properties of a series of thiosulfinates related to allicin.

Nariman Mehta: Nariman Bomanshaw Mehta (April 8, 1920 – August 22, 2014) was an Indian-born American organic chemist and pharmacologist who designed, synthesized, and patented the organic compound Bupropion, marketed under the name Wellbutrin as an antidepressant and smoking cessation aid.

Tobacco-Free Pharmacies: Tobacco-Free Pharmacies is a term used to refer to retail pharmacies where the sale of tobacco products is not available.  Outside the United States, it is rare for pharmacy stores to sell cigarettes and similar products on the same premises as over-the-counter drugs and prescription medication.  Anti-tobacco campaigners advocate the removal of tobacco from pharmacies due to the health risks associated with smoking and the apparent contradiction of selling cigarettes alongside smoking cessation products and asthma medication.  Some pharmaceutical retailers counter this argument by reasoning that by selling tobacco, they are more readily able to offer to customers advice and products for quitting smoking.

Cytisine: Cytisine, also known as baptitoxine and sophorine, is an alkaloid that occurs naturally in several plant genera, such as "Laburnum" and "Cytisus" of the family Fabaceae.  It has been used medically to help with smoking cessation.  Its molecular structure has some similarity to that of nicotine and it has similar pharmacological effects.  Like varenicline, cytisine is a partial agonist of nicotinic acetylcholine receptors (nAChRs).  Cytisine has a short half-life of 4.8 hours, and is rapidly eliminated from the body.  The use of cytisine for smoking cessation remains relatively unknown outside Eastern Europe.

List of phenyltropanes: Phenyltropanes (PTs) are a family of chemical compounds originally derived from structural modification of cocaine.  The main feature differentiating phenyltropanes from cocaine is that they lack the ester functionality at the 3-position terminating in the benzene; and thusly the phenyl is attached direct to the tropane skeleton with no further spacer (therefore the name ""phenyl""-tropane) that the cocaine benzoyloxy provided.  The original purpose of which was to extirpate the cardiotoxicity inherent in the local anesthetic "numbing" capability of cocaine (since the methylated benzoate ester is essential to cocaine's blockage of sodium channels which cause topical anesthesia) while retaining stimulant function.  These compounds present many different avenues of research into therapeutic applications, particularly in addiction treatment.  Uses vary depending on their construction and structure-activity relationship ranging from the treating of cocaine dependency to understanding the dopamine reward system in the human brain to treating Alzheimer's & Parkinson's diseases.  (Since 2008 there have been continual additions to the list and enumerations of the plethora of types of chemicals that fall into the category of this substance profile.)  Certain phenyltropanes can even be used as a smoking cessation aid ("c.f." RTI-29).  Many of the compounds were first elucidated in published material by the Research Triangle Institute and are thus named with "RTI" serial-numbers (in this case the long form is either RTI-COC-"n", for 'cocaine' "analog", or specifically RTI-4229-"n" of the subsequent numbers given below in this article) Similarly, a number of others are named for Sterling-Winthrop pharmaceuticals ("WIN" serial-numbers) and Wake Forest University ("WF" serial-numbers).  The following includes many of the phenyltropane class of drugs that have been made and studied.

Klaus Schmiegel: Klaus Schmiegel (born June 28, 1939) is most famous for his work in organic chemistry, which led to the invention of Prozac, a widely used antidepressant.  Born in Chemitz, Germany, he moved to the U.S. in 1951 to continue his education.  After he finished his schooling, Schmiegel joined Eli Lilly as a senior organic chemist; he worked there from 1968 until his retirement in 1993.  There, he collaborated with Bryan Molloy to create a new group of compounds.  One of them, fluoxetine hydrochloride, became the selective serotonin reuptake inhibitor (SSRI) used in the antidepressant medication, Prozac.  The drug, approved by the U.S. Food and Drug Administration (FDA) in 1988, has revolutionized treatment for depression.  In 1999, Schmiegel and Molloy were inducted into the National Inventors Hall of Fame and given the American Innovator Award.  Throughout his career, Schmiegel garnered eighteen patents related to the synthesis of compounds.

W. Clark Still: W. Clark Still (born 1946) is an American organic chemist.  As a distinguished professor at Columbia University, Clark Still made significant contributions to the field of organic chemistry, particularly in the areas of natural product synthesis, reaction development, conformational analysis, macrocyclic stereocontrol, and computational chemistry.  Still and coworkers also developed the purification technique known as flash column chromatography which is widely used for the purification of organic compounds.

Amfepramone: Amfepramone (INN) is a stimulant drug of the phenethylamine, amphetamine, and cathinone classes that is used as an appetite suppressant.  It is used in the short-term management of obesity, along with dietary and lifestyle changes.  Amfepramone is most closely chemically related to the antidepressant and smoking cessation aid bupropion (previously called amfebutamone), which has also been developed as a weight-loss medicine when in a combination product with naltrexone.

Bupropion: Bupropion is a medication primarily used as an antidepressant and smoking cessation aid.  It is marketed as Wellbutrin and Zyban among other trade names.  It is one of the most frequently prescribed antidepressants in the United States and Canada, although in many countries this is an off-label use.  It is an effective antidepressant on its own, but is also popular as an add-on medication in cases of incomplete response to first-line SSRI antidepressants.  Bupropion is taken in tablet form and is available only by prescription in most countries.
