Ex. 2. Some of the following sentences can be incorrect. Find the mistakes and correct them.
In early times schools of pharmacy trained people how to prepare medicinal remedies only from natural organic products.
Knowing structural characteristics of compounds with medicinal activity, chemists are able to design new drugs with better properties and fewer adverse side effects.
To develop a drug to target a specific disease, researchers try to understand the possible adverse effects of this drug that can be responsible for that condition.
Every chemical that is synthesized must be tested in vitro and in vivo.
Most entry-level workers in pharmaceutical chemistry shouldn’t have any training and have no necessary pharmaceutical and pharmacologic background after employment.
Ex. 3. Complete the following passage using the words from the box.

How do chemists "discover" drugs? Often there is an existing (1) … for a condition, and scientists will evaluate how that drug exerts its actions. Once the drug's structure is known, the drug can serve as a prototype or "lead compound" for designing more effective (2) … of similar chemical structure. (3) … compounds are molecules that have some (4) … with respect to the condition under investigation. However, the lead compound may not be effective in (5) … the disease, or it may produce undesirable (6) …. Lead optimization involves chemical modifications to the lead compound to produce a more (7) … drug, or one with fewer or decreased (8) … effects. Compounds used as medicines are most often organic (9) … , which are often divided into the broad classes of small organic molecules (e.g., atorvastatin, clopidogrel) and "biologics” (erythropoietin, insulin, glargine), the latter of which are most often medicinal (10) … of proteins (natural and recombinant antibodies, hormones, etc.). Inorganic and organometallic compounds are also useful as drugs (e.g., lithium and platinum-based agents such as lithium carbonate).
