. . . Has a history
Medicinal chemistry is the application of chemical
research techniques to the synthesis of pharmaceuticals.
During the early stages of medicinal chemistry
development, scientists were primarily concerned
with the isolation of medicinal agents found in
plants. Today, scientists in this field are also
equally concerned with the creation of new synthetic
drug compounds. Medicinal chemistry is almost
always geared toward drug discovery and development.
. . . Is carrying out basic research
Medicinal chemistry research is an important area
of research that is performed in many university
labs. As an assistant professor at the University
of Maryland School of Pharmacy, Alex Mackerell,
Jr. has done research on cocaine and cocaine analogs
to develop drugs for the treatment of cocaine
addiction. His research, however, was not solely
focused on just getting a product, but also on
understanding basic chemical reactions and their
properties. "We were interested in the physical
properties and in the underlying mechanisms of
cocaine," he says. The purpose of the research
was to develop a cocaine antagonist that would
cause ill effects when cocaine is ingested. This
type of research characterizes the research being
conducted in academic environments.
. . . Can lead to treatment of diseases
Grace Lee is using her bachelor's degree in pharmaceutical
chemistry for a different kind of drug development.
She is a part of a team of analytical chemists
at the National Institute of Health (NIH) who
formulate drugs that could be used to treat patients
with very rare diseases. These formulations are
called orphan drugs because they are used to treat
diseases found in only small portions of the population.
"We try to develop a treatment either from
scratch or from research that has already been
done in other countries," she says. "My
job is challenging because it requires working
with several different compounds at one time."
Everyday she relies on her knowledge from her
undergraduate courses in analytical and organic
chemistry. She uses this basic chemistry training
when testing and retesting compounds for safety
and efficacy, which is the measure of how well
a drug product works in the human body.
. . . Is developing guidelines
Chemists as the U.S. Food and Drug Administration
(FDA) review new drug applications from pharmaceutical
companies and are also responsible for reviewing
the processes by which the substances are made.
These chemists do not work in a laboratory, but
their role in medicinal chemistry is important.
Charles Kumkumian is the assistant director of
the Office of Drug Evaluation for the FDA which,
he says, is the largest regulatory group in the
world, employing more than 9,000 people. He says
that there are about 900 chemists employed in
various functions throughout FDA. Ten percent
of these are chemists who review new drug applications
for entirely new therapeutic entities. An equal
number of chemists review additional new drug
applications that are generic formulas or over-the-counter
dosages.
. . . Links many scientific disciplines
The focus on development of new synthetic drug
compounds has resulted in the incorporation of
many other disciplines, such as biochemistry and
molecular biology, into medicinal chemistry. "Medicinal
chemistry involves working in teams with scientists
from a variety of other disciplines," says
James Kaminski, a senior principal scientist at
Schering Plough. "There is a lot of collaboration
between chemists and biologists while searching
for a lead on a new drug or doing research on
a preclinical drug candidate. Then, when you look
into the drug safety profile, you work with toxicologists
and pharmacologists."
Joel Barrish, group/project leader in pharmaceutical
and drug discovery research at Bristol-Myers Squibb,
says that most of his time is spent coordinating
the synthetic chemistry efforts of chemists in
his group with other members of the project working
group outside of chemistry, including areas such
as biology, computer-aided design, x-ray crystallography,
metabolism and pharmacokinetics, legal and regulatory
affairs, clinical, franchise management, pharmaceutics,
and process research chemistry. Barrish says,
"Working in teams is essential to discovering
drugs because many different aspects of a molecule
must be defined to identify a candidate for clinical
studies." He adds, "Medicinal chemistry
is the drug discovery engine that provides the
tools for the rest of the organization so they
can determine the importance of particular biological
targets. Kaminski also believes that understanding
and interacting with other scientists is key to
being successful in this area. Most medicinal
chemists find that the opportunity to do research
with other scientists while helping to new drugs
is an exciting part of their work. Barrish says,
"Drug discovery research is a highly creative
and stimulating work environment where people
are driven to succeed by personal and scientific
objectives, and the desire to contribute to society's
well-being.

WORK DESCRIPTION
Medicinal chemists apply their chemistry training
to the process of synthesizing new pharmaceuticals.
They also work on improving the process by which
other pharmaceuticals are made. Most chemists
work with a team of scientists from different
disciplines, including biologists, toxicologists,
pharmacologists, theoretical chemists, microbiologists,
and biopharmacists. Together this team uses sophisticated
analytical techniques to synthesize and test new
drug products and to develop the most cost-effective
and environmentally friendly means of production.
WORKING CONDITIONS
Medicinal chemistry offers a variety of lab opportunities.
Most chemists use their research skills to formulate,
produce, and analyze new compounds. However, each
lab environment is unique-daily activities and
career opportunities differ with each one. In
academia, chemists explore a compound's different
mechanisms in basic research as well as teach
at least one full course. In government, laboratory
work is not always required, especially at the
FDA where they review drug applications. Industry,
on other hand, offers chemists a choice of moving
into management or staying in the lab.
PLACES OF EMPLOYMENT
Though a wide array of positions exist for chemists
in medicinal chemistry, the availability of these
jobs is dependent upon the economy, shifting government
regulations, and research grants. Employment prospects
include the academic environment, pharmaceutical
companies, and government. Biotechnology organizations
also employ chemists in this area. Industry provides
the opportunity to choose between a traditional
laboratory career or a non laboratory chemistry
career in management. Government also offers a
choice between a laboratory position and a non
laboratory chemistry position, such as drug application
review.
PERSONAL CHARACTERISTICS
Medicinal chemists must enjoy varied activities
and must be receptive to exploring the unknown.
A good imagination and persistence are also two
important qualities to have when considering a
career in medicinal chemistry. Being a team player
with good writing and verbal communication skills
are invaluable assets when interacting with scientists
from other disciplines.
EDUCATION AND TRAINING
Generally, pharmaceutical companies hire only
people with research experience, advanced degrees
especially in organic chemistry, and at least
two years of post-doctoral experience. Most chemists
in traditional research careers are Ph.D. chemists
while chemists with B.S. degrees generally serve
as research technicians. You can place yourself
in a competitive position by getting as much experience
as possible with a strong background in organic
chemistry and biochemistry. A number of universities
have formed medicinal chemistry programs in the
past 20 years.
JOB OUTLOOK
Because of the ever-changing economy and government
health care reform regulations, the job outlook
for medicinal chemists in today's market is mixed.
Many changes are taking place within the pharmaceutical
industry. Companies have been decreasing the size
of their research labs or merging with other companies.
Therefore, the job outlook is somewhat uncertain
for medicinal chemists. While industry is downsizing,
some government agencies are looking for chemists
to fill non laboratory chemistry positions. An
excess of jobs is not available in academia either.
Some chemists are optimistic that this downturn
is only cyclical as much research remains to be
done.
SALARY
The starting salary for a B.S. chemist ranges
from the high $20,000 to the low $30,000-per-year
range. Master's degree holders earn salaries in
the mid to high $30,000s. Salary range for Ph.D.
chemists fall in the mid $40,000 to mid $50,000-per-year
range.

WHAT YOU CAN DO NOW
Undergraduate students should maintain a high
degree of scholarship and get as much experience
as possible. Internships provide valuable experience
and are the best way to see if a career in medicinal
chemistry in a pharmaceutical lab appeals to you.
Undergraduate research in university laboratories
is another way to gain experience and as well
as become familiar with the day-to-day activities
in academia. Chemists advise undergraduate students
to get a strong background in the basic chemistry
courses and, if a research position in this areas
is desired, continue on to get an advanced degree.
