Imidazo[1,2-a]pyridine—an example of imidazopyridine and a core structure of zolpidem and some compounds described below. An imidazopyridine is a nitrogen containing heterocycle that is also a class of drugs that contain this same chemical substructure.
Omeprazole was first made in 1979 by Swedish AB Hässle, part of Astra AB. It was the first of the proton pump inhibitors (PPI). [62] [63] Astra AB, now AstraZeneca, launched it as an ulcer medicine under the name Losec in Sweden. It was first sold in the United States in 1989 under the brand name Losec.
Proton-pump inhibitors have largely superseded the H 2-receptor antagonists, a group of medications with similar effects but a different mode of action, and heavy use of antacids. [3] A potassium-competitive acid blocker (PCAB) revaprazan was marketed in Korea as an alternative to a PPI.
Pantoprazole is a proton pump inhibitor that decreases gastric acid secretion. [5] It works by inactivating (H+/K+)-ATPase function in the stomach. [9] [5] The study of pantoprazole began in 1985, and it came into medical use in Germany in 1994. [10] It is available as a generic medication.

A derivative of timoprazole, omeprazole, was discovered in 1979, and was the first of a new class of drug that control acid secretion in the stomach, a proton pump inhibitor (PPI). [11] [12] Addition of 5-methoxy-substitution to the benzimidazole moiety of omeprazole was also made and gave the compound much more stability at neutral pH. [6]

Benzimidazole is a base: . C 6 H 4 N(NH)CH + H + → [C 6 H 4 (NH) 2 CH] +. It can also be deprotonated with stronger bases: . C 6 H 4 N(NH)CH + LiH → Li [C 6 H 4 N 2 CH] + H 2. The imine can be alkylated and also serves as a ligand in coordination chemistry.
