Heterocycle compounds with antimicrobial activity

BACKGROUND: Bacterial infections are a growing problem worldwide causing morbidity and mortality mainly in developing countries. On the other hand, the increased number of microorganisms, developing multiple resistances to known drugs, due to abuse of antibiotics, is another serious problem. This problem becomes more serious for immunocompromised patients and those who are often disposed to opportunistic fungal infections. OBJECTIVE: The objective of this manuscript is to give an overview of new findings in the field of antimicrobial agents among five-membered heterocyclic compounds. These hetrocyclic compounds especially five-membered attracted the interest of scientific community not only their occurrence in nature but also due to their wide range of biological activities. METHOD: To reach our goal a literature survey that covers the last decade was performed. RESULTS: As a result, recent data on biological activity of thiazole, thiazolidinone, benzothiazole and thiadiazole derivatives are mentioned. CONCLUSION: It should be mentioned that despite the progress in the development of new antimicrobial agents there is still room for new findings. Thus, research still continues.
