Abstract

This chapter is a comprehensive account of the medicinal chemistry of antihistamines, H2 receptor (H2R) blockers, H3 receptor (H3R) blockers, and proton pump inhibitors (PPIs). It provides the mechanism of drug action and detailed structure-activity relationship (SAR) of the drugs in these classes to give the knowledge base for pharmacists. After studying this chapter, students will be able to:

 • Describe the physiochemical properties of histamine and histamine receptors.

• Identify chemical classifications and describe the SAR of antihistamines, H2R and H3R antagonists.

• Differentiate receptor binding patterns and structural features between histamine receptor agonists and antagonists.

• Distinguish between sedating and non-sedating antihistamines, as well as the first-, second- and third-generation antihistamines.

• Describe the structural features of cromolyn and related mast cell stabilizers and their therapeutic applications.

• Discuss the proton pump inhibitors, including their development, mechanism of action, and structural and physicochemical features.

• Apply the medicinal chemistry principles to the clinically relevant case studies.

• Explain the drug discovery story of representative drugs of different classes.
