Abstract: The infectious diseases caused by bacterial resistance to antibiotics constitute an increasing
threat to human health on a global scale. An increasing number of infections, including tuberculosis,
pneumonia, salmonellosis and gonorrhea, are becoming progressively challenging to cure owing
to the ineffectiveness of current clinically used antibiotics and presents a serious health threat
worldwide in medical community. The major concern of this global health threat is the ability of
microorganisms to develop one or several mechanisms of resistance to antibiotics, making them inefficient
to therapeutic treatment. The quest for discovering novel scaffold with antimicrobial property
is particularly in great need to face future challenges in hospital and healthcare settings. Hence,
the development of benzothiazoles is of considerable interest to medicinal chemists. Benzothiazole,
being part of an important class of heterocyclic scaffold retains a wide spectrum of various attractive
pharmacological activities. Antibiotic resistance represents an increasing burden comprising
medical cost, hospital stay and mortality. Several derivatives containing a benzothiazole scaffold,
reported in the literature, were found to display remarkable potencies towards diverse Grampositive
and Gram-negative bacterial pathogens. The principal focus concerns the antibacterial potential
of benzothiazole-based derivatives as antimicrobial agents interacting with targets in bacterial
pathogens. In this review, we also disclose the significance of the benzothiazole moiety in the
discovery of new antibacterial compounds, the potential of benzothiazole-based derivatives in the
case of resistant bacterial strains, optimization of their antibacterial activity, and their future perspectives.
The structure-activity relationship study and the mode of action of the title derivatives are
highlighted too.
