This course provides a comprehensive introduction to the principles and applications of Computer-Aided Drug Design (CADD) in modern drug discovery. It covers key stages of the drug discovery pipeline, emphasizing how computational tools accelerate target identification, lead optimization, and virtual screening. Topics include ligand-based and structure-based drug design, QSAR modeling, molecular docking, pharmacophore modeling, and ADMET prediction. Through real-world case studies, participants will explore practical applications of CADD in designing therapies for important diseases such as HIV, cancer, and malaria.
