Hantzsch Dihydropyridine (Pyridine) Synthesis

But this is only the first step; a promising drug lead must then be intensely studied to make sure that it can actually be turned into a practical drug. Its molecular structure can often be modified in order to optimize properties such as solubility, toxicity, and potency. This process can take years, and failure rates are very high; the cost of bringing a new drug to market is often as much as $100 million.

Once a drug candidate has been found, its molecular structure can often be modified in order to ohydrate structure. Computer-modeling is an essential tool in this work.

Virtually all chemical changes involve the uptake or release of energy, usually in the form of heat. It turns out that these energy changes, which are the province of , serve as a powerful means of predicting whether or not a given reaction can proceed, and to what extent. Moreover, all we need in order to make this prediction is information about the energetic properties of the reactants and products; there is no need to study the reaction itself. Because these are bulk properties of matter, chemical thermodynamics is entirely macroscopic in its outlook.

In its most general meaning, the term can describe kind of particle (even a single atom) having a unique chemical identity. Even at the end of the 19th century, when compounds and their formulas had long been in use, some prominent chemists doubted that molecules (or atoms) were any more than a convenient model.

What is Chemistry all about? - Steve Lower's Web pages

In the preceding section we looked at chemistry from a conceptual standpoint. If this can be considered a "macroscopic" view of chemistry, what is the "microscopic" view? It would likely be what chemists actually do. Because a thorough exploration of this would lead us into far more detail than we can accommodate here, we will mention only a few of the areas that have emerged as being especially important in modern chemistry.

The , by contrast, is a microscopic concept which in modern chemistry relates the unique character of every chemical element to an actual physical particle.

"In the early 1900's a chemist could analyze about 200 samples per year for the major rock-forming elements. Today, using modern tools, two chemists can perform the same type of analyses on 7,000 samples per year."

begins by identifying the particular protein or other target that must be attacked or modified in order to alleviate a disease. By means of computerized molecular modeling, a candidate drug molecule is developed that can bind to the target and, in so doing, modify its behavior.
