It was not until the early 1800s that scientists began extracting chemicals from plants with purported therapeutic properties to isolate the active components and identify them.By discovering and structurally characterizing compounds with medicinal activity, chemists are able to design new drugs with enhanced potency and decreased adverse side effects.New technologies have made it possible to assay large numbers of compounds in a short period.High-throughput drug screening allows pharmaceutical chemists to test between 1,000 and 100,000 chemicals in a single day!Thinkwell Chemistry is available 24/7 for one fixed price, instead of by the hour, so it's better than a tutor, too. Gordon Yee is an associate professor of chemistry at Virginia Tech in Blacksburg, VA. A widely published author, Professor Yee studies molecule-based magnetism. from Yale University and carried out postdoctoral research at Harvard University.If you're preparing for the Chemistry AP test, check out Thinkwell's AP Chemistry, which includes diagnostic assessments geared towards AP exam preparation. Tarek Sammakia is a Professor of Chemistry at the University of Colorado at Boulder where he teaches organic chemistry to undergraduate and graduate students. He has received several national awards for his work in synthetic and mechanistic organic chemistry.
Herbal medications and folk remedies dating back to ancient Egyptian, Greek, Roman, and Asian societies were administered without any knowledge of their biological mechanism of action.

It's taught by top professors from prestigious universities, so you'll have help from our nation's best chemistry teachers whenever you need it.
To develop a drug to target a specific disease, researchers try to understand the biological mechanism responsible for that condition.
If the biochemical pathways leading up to the disease are understood, scientists attempt to design drugs that will block one or several of the steps of the disease's progress.Chemists can vary the atoms or groups within the model and predict the effect the transformation has on the molecular properties of the drug. Advances in technology have made it possible for medicinal chemists to synthesize a vast number of compounds in a relatively short time, a process referred to as combinatorial chemistry.
