Molecules with benzimidazole derivatives serve important functions as therapeutic agents and have shown excellent results in clinical and biological research. In this comprehensive review, we summarize marketed medications that include the benzimidazole moiety. Here, we discuss two topics: PPIs and H1 receptor antagonists. Benzimidazole derivatives are important in all fields because they have the same isostructural pharmacophore as that of naturally occurring active biomolecules. While PPIs and H1 receptor antagonists are generally safe in the short term, accumulating data suggest that their long-term use may pose concerns. This systematic review aimed to assess global PPI use in the general population. This will help researchers, medicinal chemists, and pharmaceutical scientists to create breakthrough benzimidazole-based drugs. This review can help identify novel lead compounds and optimize existing benzimidazole derivatives to improve medicinal efficacy.

There are multiple driving forces, and increasing attention has been gained over the past two decades regarding chronic inflammation, which represents a pivotal factor owing to its ability to establish or maintain an environment that is permissive for tumor initiation, growth, and progression. This review details the interplay between inflammation and cancer by highlighting how chronic inflammation fuels oncogenesis by promoting genetic instability, immune evasion, and a setting rich in pro-tumorigenic signaling. This review explains how various inflammatory mediators, including cytokines and transcription factors, can potentially create tumor microenvironments by drawing on case studies and recent research data. Furthermore, this article provides insights into the molecular mechanisms of Nuclear Factor Kappa B (NF-κB)-regulated pathways and inflammasomes and provides essential molecular links between inflammation and tumorigenesis. Furthermore, novel therapeutic approaches using nanotechnology and immunotherapy are also discussed. Nanotechnology offers precise drug delivery with increased targeting to tumor sites, whereas immunotherapy, including immune checkpoint inhibitors, attempts to restore the functionality of the immune system to recognize and destroy cancer cells. Thus, a combination of these approaches represents a promising new frontier in cancer treatment that addresses both the inflammatory and immune dimensions of oncogenesis.

Hypoxia drastically decreased OxPhos flux by 2-3 times in 2D models, similar to what occurs in mature multicellular tumor spheroids (MCTS), a representative 3D cancer cell model. However, mitochondrial protein contents and enzyme activities were significantly different between both models. Moreover, glycolytic fluxes were also significantly different between 2D and MCTS. The glycolytic flux range in 2D models is 1-34 nmol lactate/min/mg cellular protein, whereas in MCTS the range of glycolysis fluxes is 60-80 nmol lactate/min/mg cellular. In addition, sensitivity to anticancer canonical and metabolic drugs was greater in MCTS than in 2D.
