Question

The most useful classification of drugs for medical chemist is _____________
A) On the basis of chemical structure
B) On the basis of drug action
C) On the basis of molecular targets
D) On the basis of pharmaceutical effect

Answer 1

As we know that in the modern world, medical chemistry plays a vital role in our daily life. In medicinal chemistry choosing a drug for the specific disease is the most challenging job. Host and guest like a way to design the drug for disease in medical chemistry.

Complete step by step answer:
We have to know that during the design of drugs which have various classification in medical chemistry. There are,
1.Based on the chemical structure of the drug
2.Based on the drug action in our body
3.Based on the solubility of the drug
4.Based on the molecular target
5.Based on the pharmaceutical effect of the drug.
We have to know the chemical structure of the drug, various drugs able to design and prepare in drug. The some functional groups and substitution groups in the structure. This sometimes affects the reactivity of the drug in another environment. So, the drug design based on the structure is sometimes not applicable.
Therefore, option A is not the correct answer.
As we know that the drug design is based on the action, it also gives some problems oxidation and reduction of the drug. For example, one drug is designed based on the functional group of an amine compound, but it is oxidised to form nitro compound means, that affect the entire reactivity of the drug.
Therefore, option B is not the correct answer.
We need to know that the pharmaceutical effect of the drug is various from one person to another person. The amount of drugs is mainly in medicinal chemistry. Over intake of drugs leads to some problems or death also. So, the pharmaceutical effect of the drug is a suitable way for design of drugs.
Therefore, option D is not the correct answer.
We must remember that the one drug designed for the guest and host method is the correct way. In this way design of drug like lock and key method. Drug to attack over target like a key to affect the target. This classification of designing only able to give best result. One drug to attack the target and destroy them. This is ultimate aim for drug designing in medical chemistry.
Therefore, the most useful classification of drugs for medical chemists is on the basis of molecular targets.
Therefore, option C is correct.

Note:
We have to remember that in drug designing level of test to reach the human. One drug passes a three phase test only able to intake humans. Medicinal chemistry gives a solution to various problems in our life. Drug design based on the target is the easiest way to cure that disease. Design of drugs today is started by software through computational studies and comes from laboratory reaction.
