27 Chemistry in Everyday Life
ˆ Drugs
ˆ Up to 19th century, plant based natural drugs were used in crude form e.g. powder or boiled
drink of bark, roots and leaves of tree etc.
ˆ The bark of Cinchona tree and quinine obtained from it, were used for Maleria.
ˆ Treatment of diseases in which parasites live (virus, fungi, yeast, bacteria, protozoa worm) are
killed and their growth is inhibited by chemical in body is called chemotherapy.
ˆ German chemist Paul Ehrlich is known as father of chemotherapy.
ˆ Ehrlich synthesized arsenic containing compounds (salvarsan and neo salvarsan) for skin
diseases like syphilis and for sleeping sickness.
ˆ Classification of Drugs
ˆ On the basis of pharmacological effect :
– useful for doctors.
– body pain relieving drugs can be classified as analgesic drugs.
– Drugs, killing or inhibiting the growth of micro organisms that cause harmful effect on
wound or injury can be classified as antiseptic drugs.
ˆ On the basis of drug action :
– Some problems occur in body due to release of histamine such as common cold, acidity,
swelling, redness of skin and itching. Therefore, the drugs used to stop the release of
histamine are classified as separated as of antihistamines.
ˆ On the basis of chemical structure of drugs :
– Drugs containing similar chemical structure are included in same class.
– eg. sulphonamides have common structure as follows :

H2N SO2NHR where R = aromatic or heterocyclic group

ˆ On the basis of molecular targets of drugs :
– Biomolecules such as carbohydrates, lipids, proteins and nucleic acids. These biomolecules
are called target molecules of drugs.
ˆ Working Mechanism of Drugs
ˆ Some proteins perform the role of biological catalysts in the body which is known as enzymes.
ˆ Some proteins are crucial to communication system in the body which is known as acceptors.
ˆ Nucleic acid have coded genetic information for the cell.
ˆ Lipid and carbohydrates are structural parts of the cell membrane.
Drug-Enzyme Interaction :
ˆ Generally substrate is bound with active site of enzyme. Drugs stop this reaction of enzymes
for this drugs stop the substrate from binding with active site of enzyme. This drugs are called
enzyme inhibitors.
ˆ Drugs, stop the substrate to bind with active site of enzymes in two ways.

688

ˆ Competitive inhibitors :
– Drugs compete with natural substrate for their attachment on the active site of enzymes.
Such durgs are called competitive inhibitors.

Drug Drug
Active size

Enzyme

Substrate Enzyme Substrate

ˆ Allosteric site :
– Some drugs do not bind to the active site of enzyme but bind to a different site. This site
is called ‘allosteric site’.
– This type of binding of drug with enzyme results in the change in shape of active site
therefore substrate cannot bind with it.

Active site with changed
Active site place

Allosteric site
Enzyme Inhibiror
(Inhibitor occupying)
allisteric site

ˆ Drug-Receptor Interaction
ˆ In the body, message between two neurons to muscles is communicated through certain chemicals.
These chemicals are called chemical messengers.

ˆ Drugs bind to receptor site and stop communication process of cell. These drugs are called
antagonists.

ˆ If the messenger shaped drug is used, then receptor accept it and under the impression of
natural messenger the communication process occurs. These drugs are called agonists.

ˆ Antagonists is competitor and Agonists is contender.
