Background: Imidazo[2,1-b]thiazole, a well-known fused five-membered hetrocycle is
one of the most promising and versatile moieties in the area of medicinal chemistry. Derivatives of
imidazo[2,1-b]thiazole have been investigated for the development of new derivatives that exhibit
diverse pharmacological activities. This fused heterocycle is also a part of a number of therapeutic
Objective: To review the extensive pharmacological activities of imidazo[2,1-b]thiazole derivatives
and the new molecules developed between 2000-2018 and their usefulness.
Method: Thorough literature review of all relevant papers and patents was conducted.
Conclusion: The present review, covering a number of aspects, is expected to provide useful insights
in the design of imidazo[2,1-b]thiazole-based compounds and would inspire the medicinal
chemists for a comprehensive and target-oriented information to achieve a major breakthrough in
the development of clinically viable candidates.
