Thiophene

Thiophene a five member heterocycles had been found with enormous biological activities with the suitable modifications in the structure. The present review is an attempt made to direct the attention of the researchers towards the thiopene ring for the development of newer chemical entities which are quite useful in the treatment of various life threatening diseases and disorders This review article covers the most active thiopene derivatives that have shown considerable biological actions such as antimicrobial, anti-inflammatory. This review also discusses the structure-activity relationship of the most potent compounds. It can act as an important tool for medicinal chemists to develop newer compounds possessing thiopene moiety that could be better agents in terms of efficacy and safety

  A series of thiophene and aryl substituted compounds 1a-f; 2a-b and 3a-c were synthesized by Erlenmeyer azolactone synthesis. These compounds were screened for antimicrobial activity method in vitro. Among the tested compounds 3c showed significant activity and some of the other compounds showed promising activity. The structure of new compounds synthesized during present investigation have been authentically established by their IR,1H NMR and Mass spectra and some QSAR studies. Key words: Thiophene; antimicrobial; antibacterial; antifungal.
