THE MOST COMMON ORGANIC CHEMICAL ELEMENTS• Medicine in pre-scientific times• Synthetic organic chemistry and medicine• Alkaloids• glycosides• Foxglove (digoxin)• Willow bark (aspirin)• quinine• Ephidrine
Herbals•Many herbals, illustrated books describing plants andtheir uses, were published. Practical uses together witha lot of mysticism, superstition, and what we nowconsider pseudoscience: astrology for example.•Doctors and other healers had gardens where theygrew useful plants. Others were harvested from thewild.
Systems of Medicine• Our present system, scientific medicine, is only 200 years old or so. There have been many other concepts in medicine, and there continue to be alternative systems of medicine. These other systems often contain concepts that are specifically denied or disproved by science.• Hippocrates and the Four Humors: blood, phlegm, black bile, and yellow bile. The humors have properties of hot, cold, wet and dry. In disease, the humors get out of balance. The theory formed the basis of Western medicine until the 1850’s or so. – We get words for personality traits like sanguine, phlegmatic, choleric, and bilious from this theory. – This theory also encompasses the idea of the four elements: earth, air, fire, and water.• Traditional Chinese medicine and Ayurveda (traditional Indian medicine) are also alternative theories of medicine that remain popular.• Francis Bacon, an early scientific philosopher, said. ‘This is the foundation of all. We are not to imagine or suppose, but to discover, what nature does or may be made to do”.
Scientific Testing• The essence of the scientific method is the controlled experiment: the subjects are divided into two groups, with one group given the experimental treatment and the other given a control treatment. – The control treatment should be as similar to the experimental as possible, just missing the one element being tested. – A useful refinement: double-blind experiments, where neither the patients nor the doctor knows who is getting the experimental treatment and who is getting the control. This avoids the placebo effect, where patients often get better even with a control treatment.• Statistical analysis of the results is necessary, because random factors influence the results. An important feature of statistics: using enough subjects to get statistically significant results.• Animal models for the disease are very useful: you can do more experiments without upsetting patients and their families. – More recently, tissue culture cells and even simpler model
Active Principles• A big idea from the early 1800’s: The reason that certain plants are effective against particular diseases is because they contain specific chemical compounds (the active principles) , with the rest of the plant material irrelevant. – If you isolate (or synthesize) the active principle, you can control the dosage people are given and avoid giving them other plant compounds that might have bad side effects. – In contrast, the amount a plant contains can vary with environmental conditions, age of the plant, the plant’s genetics, and many other factors. – Also, it is possible to determine whether a given plant is actually effective, or which parts of mixtures are important.• This concept led to people trying to extract the active principles from plants. For instance: which works better, soaking the plant material in cold water, hot water, alcohol, etc.? Which part of the plant produces the most active principle? – Lots of help from alchemy, the precursor to modern chemistry.
Medicinal Chemistry• The effect of organic chemistry and the scientific method: useful compounds are still isolated from plants: taxol is a recent example. However, once isolated, attempts are made to synthesize them and modify them. – This helps avoid the supply of the plant from being cut off due to disease or political or economic reasons. – The Germans pioneered this philosophy of self-sufficiency in the 1800’s because they had poor access to the ocean trade routes and very few overseas colonies. – Also, synthesizing an active principle from scratch proves that you really do understand its structure.• It is worth considering whether the healing effect of a plant is due solely to a single active compound, with all others irrelevant. There are many cases where several compounds acted synergistically. And, healing is also helped by the placebo effect and also by careful individual attention from a healer. We are not just biological machines that respond uniformly to impersonal treatment.
Active Principles in Plants• The value of plants as medicine come from specific chemical compounds they contain. These compounds are secondary metabolites: not directly related to the plant’s ability to grow or reproduce.• Secondary metabolites are probably present as a defense against infection by bacteria or fungi, or to prevent insects and other animals from eating them. – Some secondary metabolites inhibit other plant species: they poison the soil. – Also, some are used to attract animals to help with pollination and seed dispersal: the scents of fruits and flowers, for example.• Different species produce different secondary metabolites. Within plant families, the secondary metabolites are similar. For instance, the carrot family and mustard family.• A 2001 study counted 122 compounds used in medicine that were derived from traditional herbal medicine. Of these, 80% were used for the purpose the herbalists said they were good for. Traditional herbal medicine is a very useful starting point for drug discovery. – It is thought that about 10,000 different plants have been used in herbal medicine at some point in human history.
Major Groups of Secondary Metabolites • Alkaloids. Many different compounds, found in many plants. They all contain nitrogen atoms, are alkaline (basic), and taste bitter. Structures vary widely. – Often affect the nervous system. Whether this is good or bad depends on dosage and your point of view. For example, morphine. • Glycosides. A sugar is attached to the active component. This makes them non-toxic until an enzyme removes the sugar, which happens in the digestive system. – Cyanogenic. Very simple: cyanide attached to a sugar. Remove the sugar and release the poison: it stops the ability to make ATP. – Steroid. Steroids have a particular ring structure and are used to make hormones in animals. Two main types: • cardioactive (meaning that they affect your heart). • Saponins are soapy and very toxic: they work especially well as fish poisons because they dissolve easily in water. The steroid found in yams (Dioscorea) is a saponin.

Aspirin• Today, aspirin is probably the most widely used synthetic drug. However, it originated in the plant world.• The inner bark of willow trees, made into a tea, has been used for relief of pain, fever, and inflammation since ancient times.• The active ingredient in willow bark is salicylic acid. It is a plant hormone: it is released when the plant is wounded, and stimulates the cells to strengthen their cell walls and produce enzymes and other compounds to fight the infection. – It also gets converted to a volatile form, methyl salicylate (which is Oil of Wintergreen). This compound induces pathogen defense mechanisms in nearby plants.• Salicylic acid was extracted from willow bark in the early 1800’s.
Vinca Alkaloids• The Madagascar periwinkle Catharanthus roseus (used to be Vinca rosea) was used as a traditional Chinese remedy for diabetes. In the 1950’s it was tested scientifically, and it had little effect on diabetes. However, the scientists noticed that it suppressed bone marrow activity. This led to the finding that the lifespan of mice with leukemia was significantly prolonged by Vinca extracts. Vinca contains over 70 different alkaloids, but purification work isolated vincristine and vinblastine as the active agents.• These drugs prevent cell division by binding to the mitotic spindle, the apparatus that pulls the chromosomes apart. It binds to the spindle proteins, preventing them from joining together.• They are very useful in treating leukemia, which is cancer of the bone marrow cells that produce blood cells. It also helps with several other cancers.

OLIVE OIL AND ITS BENEFITSBENECOLA large number of scientific studies have investigated the effect of plant sterols on blood cholesterol levels. It is apparent from these studies that plant stanols lower total and LDL cholesterol, but beneficially do not lower good HDL cholesterol or have any adverse effects on triglyceride levels. Plant stanol ester reduces serum sterols by inhibiting their absorption from the small intestine. Reducing serum cholesterol through dietary changes often only provides short-term benefits due to the difficulty of making the changes permanent. Benecol® products maintain its effectiveness in long-term use, when the product is consumed on a daily basis. In a 12-month trial, serum cholesterol was reduced by 10% and LDL by 15%.These significant cholesterol lowering results have been proven on:-People with normal and increased cholesterolemia-Men, women and children-Patients suffering from coronary disease-Patients with diabetes type 1 and 2-In combination with a healthy, balanced diet, rich in fruit and vegetables-In combination with a strict lipid lowering diet-In combination with medical treatment with statins to lower cholesterol
