Hepatocellular carcinoma (HCC) is rapidly spreading around the world with a high mortality rate. In the low- and middle-income nations most impacted by HCV and HBV infections, HCC places a significant strain on the healthcare system and leaches productive capability. An extensive study on HCC to create novel therapeutic approaches was motivated by the lack of adequate preventive or curative therapy methods. Several medications have been put forward and some drug molecules are under investigation by the Food and Drug Administration (FDA) for the treatment of HCC. However, these therapeutic choices fall short of the ideal due to toxicity and the rapid rise in drug resistance which decreases the efficacy of these therapeutics and leads to the severity of hepatocellular carcinoma. Therefore, concerning these problems, there is a critical need for novel systemic combination therapies as well as novel molecular entities that target various signalling pathways, reducing the likelihood that cancer cells may develop treatment resistance. In this review, we discuss the conclusions of several studies suggesting that the N-heterocyclic ring system is a key structural component of many synthetic drugs with a diverse range of biological activities. Following nuclei, such as pyridazine, pyridine, and pyrimidines, along with benzimidazole, indole, acridine, oxadiazole, imidazole, isoxazole, pyrazole, quinolines, and quinazolines, have been included to provide a general overview of the link between structure and activity between heterocyclics and their derivatives against hepatocellular carcinoma. A comprehensive investigation of the structure-activity relationship between the series may be done by the direct comparison of anticancer activities with the reference.
