Abstract

Quinoline-5,8-diones, also referred to as 5,8-quinolinediones or quinolinequinones, have been researched extensively for their antiproliferative effects, where they displayed great results. Other than anticancer, they exhibit multiple activities such as antimalarial, antiviral, antibacterial, and antifungal activities. Natural quinolinequinones have also been known for their significant activities. The review highlights the diverse biological activities exhibited by synthetic quinoline- 5,8-diones over the past two decades. Continued research in this field is warranted to fully exploit the therapeutic potential of these intriguing compounds and their derivatives for future drug development. By comprehensively evaluating the therapeutic applications and biological activities of quinoline-5,8-dione derivatives, this review endeavors to provide researchers and practitioners with a valuable resource that will foster informed decision-making and inspire further investigations into harnessing the immense potential of this intriguing scaffold for the benefit of human health.

Keywords: Quinoline-5, 8-dione, biological activity, anticancer, heterocycle, natural antibiotics, quinolinequinones.
