The main goal of this article is to present selected syntheses, structures and a various biological activity of imidazo[4,5-b]pyridine derivatives. During the past 20 years the biological activity of imidazo[4,5-b]pyridine have been intensively studied. Based on the review of the chemical literature, it was shown that derivatives of imidazole[4,5-b]pyridine showed a multipharmacological effects such as antibacterial effect [20–22] and antituberculotic activity [25–33], nonsteroidal antiinflammatory activity [35–43] and analgesic [44, 45] effect. Among compounds of this class antagonists of angiotensin II receptors that exhibit hypotensive activity are also known [9–11]. Compounds containing imidazo[4,5-b]pyridine moiety can be synthesized from different substrates. The most useful starting compounds for the synthesis of imidazo[4,5-b]pyridine are derivatives of 2,3-diaminopyridine [1–3].

This review presents most of the literature data about imidazo[4,5-b]pyridine derivatives and their biological activity. The main goal of this paper is to present various methods for the preparation of imidazo[4,5-b]pyridine analogues. There are some drugs, imidazo[4,5-b]pyridine derivatives, registered in the world, which exhibit diverse pharmacological activities. Noberastine [4] represent antihistaminic II generation drug with selective activity to H1 receptors. Tenatoprazole [5] is a novel proton pump inhibitor with a prolonged plasma half-life which possesses antiulcer activity. Sulmazole [3] is a new cardiotonic agent, an A1 adenosine receptor antagonist. Based on the review of the chemical literature, derivatives of imidazole[4,5-b] pyridine showed a multipharmacological effects. Presented compounds exhibit anticancer [14, 17, 19], antidepressant [44, 45], cardiotonic, anticoagulant [37] activities. Some of them can be used in the treatment of heart diseases [3]. There were also described derivatives of imidazo[4,5-b]pyridine with the potential use in the treatment of diabetes [48], hypertension and hyperlipidemia. Some chemical compounds which contain in their structure the imidazo[4,5-b]pyridine system inhibit neurodegeneration [34, 38] and can be used in the treatment of neurodegenerative disorders eg. Parkinson’s disease, Alzheimer’s disease or multiple sclerosis. In addition, some of the imidazo[4,5-b]pyridine possess antivirial [40–42], antimicrobial and cytotoxic activities.
