Dihydropyrimidines were produced synthetically by multicomponent reactions such as the Biginelli reaction. Because of their remarkable biological characteristics, dihydropyrimidinones (DHPMs) have drawn considerable attention in recent years. In this chapter, we have described the synthetic and pharmacological properties of DHPMs employing multicomponent synthesis. It emphasizes also widespread pharmaceutical applications of DHPMs, including antitubercular, antifilarial, antihypertensive, antiinflammatory, anticancer, antifungal, antibacterial, anti-HIV, antihyperglycemic, anti-SARS, analgesic, antioxidant, anticonvulsant, anti-Alzheimer�s and antihepatitis properties. This chapter will be of immense importance for the scientists working in this area. � 2023 Elsevier Inc.
