Purpose of the Study:

• To review the types and consequences of reactive metabolite formation.
• To discuss current methods for evaluating the bioactivation potential of new drug compounds.
• To explore reasons behind the safety of certain bioactivatable drugs and guide future development.

Main Methods:

• Literature review of reactive metabolite formation and toxicity.
• Analysis of current bioactivation assessment strategies, including their pros and cons.
• Exploration of case studies and factors contributing to drug safety.

Main Results:

• Reactive metabolites are a significant cause of drug-induced toxicity.
• Various methods exist to assess bioactivation potential, each with limitations.
• Certain factors can mitigate the risks associated with bioactivatable drugs.

Conclusions:

• Proactive assessment of reactive metabolite formation is essential for drug development.
• Guidance from understanding safe bioactivatable drugs can improve candidate selection.
• This approach aims to enhance the safety profile of new drugs entering the market.
