Sodium Dichloroacetate (DCA) stands as a compound with substantial research interest, spanning its potential in cancer therapy and neurological health. However, its journey towards widespread clinical adoption involves navigating complex research landscapes and understanding its safety profile.

Clinical Research and Applications:

DCA's primary mechanism of action, targeting cellular metabolism by inhibiting pyruvate dehydrogenase kinase (PDK), has positioned it as a candidate for both cancer treatment and the management of metabolic disorders. In oncology, research focuses on DCA's ability to reverse the Warburg effect in cancer cells, promote apoptosis, and potentially synergize with conventional therapies. Clinical trials are exploring its efficacy in various cancer types, often as an adjunct therapy. Beyond cancer, DCA is being investigated for its neuroprotective effects in conditions like lactic acidosis, stroke, and neurodegenerative diseases, where metabolic dysfunction plays a key role.

Safety Considerations and Peripheral Neuropathy:

A significant aspect of DCA's clinical profile is the potential for adverse effects, most notably peripheral neuropathy. This side effect is dose-dependent and can be influenced by individual metabolic differences, particularly related to the enzyme glutathione transferase zeta 1 (GSTZ1). Research into pharmacogenetics and personalized dosing strategies, based on GSTZ1 genotypes, is crucial for managing this risk. Understanding the drug's metabolism and identifying strategies to mitigate toxicity, such as co-administration with thiamine or the use of targeted drug delivery systems, are active areas of investigation.

Future Prospects and Conclusion:

The continued exploration of DCA involves refining its therapeutic applications, optimizing dosages, and ensuring patient safety. The development of nanocarrier-based drug delivery systems offers a promising avenue to improve DCA's targeted delivery and reduce systemic exposure, potentially minimizing side effects. As research progresses, DCA represents a key example of how metabolic modulation can be harnessed for therapeutic benefit. While further robust clinical trials are essential to solidify its place in therapeutic protocols, the ongoing scientific inquiry into DCA highlights its significant potential for addressing challenging diseases.
