• Structure-activity relationships (SAR) and molecular targets are also discussed.

Key Points:

• Benzothiazole derivatives are prevalent in naturally occurring compounds and marketed drugs.
• The formation of benzothiazole-hydrazone derivatives offers a route to novel pharmacologically active agents.
• Understanding SAR is critical for optimizing drug candidates based on these scaffolds.

Conclusions:

• This review provides medicinal chemists with extensive information on benzothiazole and benzothiazole-hydrazone derivatives.
• It serves as a valuable resource for future drug discovery and development efforts.
• The study underscores the therapeutic versatility of nitrogen- and sulfur-containing heterocycles.
