anesthetic effects of carbamates along with
stimulating the breathing have been confirmed.
―This effect can be associated with the
carbamate NH2 group, so that the character of
the effects of this compound is preserved,‖
Schmiedeberg wrote [33]. This work by
Schmiedeberg is noteworthy for three reasons.
First, it shows that the pharmacological
principles and the biological effects of drugs
depend on their chemical structure. Second,
this work described a completely new
anesthetic which is still used on animals. Third,
the discovery led to a number of significant
discoveries of sleeping pills and sedatives such
as bromisoval, barbiturates, and
benzodiazepines.
Synthesis of urea. Schmiedeberg is
considered the founder of the synthetic theory
of the formation of urea from ammonium
carbonate. According to this theory, urea is
formed by the dehydration of carbamide-acid
ammonium, which can be considered as an
intermediate stage of dehydration from
ammonium carbonate. When working in
Dorpat, Schmiedeberg suggested that
ammonium was part of urea. His further
experiments in Strasbourg confirmed this
suggestion, and his student Waldemar von
Schroeder demonstrated that the synthesis of
urea from ammonium carbonate took place in
the liver [34]. This knowledge was important
for understanding the process of reducing the
acid-base balance in the formation of urea in
the liver in favor of increasing the formation of
ammonia in the kidneys in acidosis. The
synthetic theory of urea formation in the form
in which it was developed and substantiated by
the works of scientists of the 19th century,
existed with no change until the 30s of the 20th
century. In 1932, there appeared a new theory
of Krebs and Henseleit (1900-1981), which
revealed the participation of new compounds in
the synthesis of urea. This theory was followed
by a further discovery of the Krebs cycle, for
which Krebs was awarded the Nobel Prize in
Physiology and Medicine in 1953.
Schmiedeberg also gave the first chemical
definition of the protein structure free from
other impurities, by examining cartilage tissue.
He managed to identify the structure of
chondroitin [21].
Schmiedeberg Research School
Oswald Schmiedeberg began his research
under the supervision of Rudolf Richard
Buchheim in Dorpat in the world‘s first
pharmacological research institute. At the
beginning of his scientific career, Buchheim
turned his own apartment into a research lab.
Besides Schmiedeberg, Buchheim supervised
about 90 post-graduate students and stated his
thoughts in essays and books. However, none
of Buchheim‘s initiatives and ideas would have
ever been further developed, if pharmacologist
Oswald Schmiedeberg had not become one of
his doctoral students. Thanks to
Schmiedeberg‘s own research and the fact that
he had approximately 120 disciples from 20
countries – pharmacology and the
pharmacological school of Strasbourg got in
vanguard and was studied worldwide, and the
majority of well-known pharmacologists in the
first half of the 20th century were his students
(Fig. 7, 8). Schmeideberg‘s research activity
was largely aimed at finding the correlation
between the chemical structure of substances
and their effectiveness as drugs. During his life,
O. Schmiedeberg wrote over 200 scientific
books and articles, and his research is
sometimes considered a major factor
determining the success of the German
pharmaceutical industry prior to World War II
[5, 24, 35, 36].
