Diversity and Multi-Target Potential of Pyrazole, Imidazole or Triazole Derivatives in Modern Anticancer Therapy

Cancers are intricate and multifactorial diseases. Despite progress in medicine, there are still some obstacles in their treatment due to drug resistance, the toxicity of combination therapy and lack of drug selectivity toward cancer cells. The solution to this may be multi-target directed ligands (MTDLs), which have gained more and more popularity over the years. This review presents a comprehensive overview of novel potential multi-targeted derivatives of nitrogen-containing heterocycles, as imidazole, pyrazole, 1,2,3-triazole and 1,2,4-triazole. The review gathers the selected literature from 2006 to 2026. The analysis focuses on the potency of the inhibitory activity of selected molecules against a variety of molecular targets, as well as on their interactions with protein binding sites. Additionally, the structure-activity relationship (SAR) studies within the collected series are included. The discussion may contribute to the development of new multi-target anticancer agents.
