‘Medicinal Chemistry III – Theory’ is a course offered in the sixth semester of B. Pharm program at School of Pharmacy, Health Sciences campus, Amrita Vishwa Vidyapeetham.

Course Duration: 45 Hours

Scope:

This subject is designed to impart fundamental knowledge on the structure, chemistry and thera- peutic value of drugs. The subject emphasis on modern techniques of rational drug design like quantitative structure activity relationship (QSAR), Prodrug concept, combinatorial chemistry and Computer aided drug design (CADD). The subject also emphasizes on the chemistry, mechanism of action, metabolism, adverse effects, Structure Activity Relationships (SAR), therapeutic uses and synthesis of important drugs.

Objectives:

Upon completion of the course student shall be able to

1. Understand the importance of drug design and different techniques of drug design.
2. Understand the chemistry of drugs with respect to their biological activity.
3. Know the metabolism, adverse effects and therapeutic value of drugs.
4. Know the importance of SAR of drugs.
