Summary
Selective antiviral chemotherapy has improved viral infection outcomes. New research continues to seek more effective and less toxic antiviral drugs to combat viral diseases and overcome drug resistance.
Area of Science:
- Virology
- Medicinal Chemistry
- Pharmacology
Context:
- Antiviral chemotherapy has significantly improved outcomes for many viral infections.
- Early antiviral compounds often exhibited host cell toxicity, limiting their use.
- The development of antivirals accelerated with the HIV-1 epidemic.
Purpose:
- To review the historical development and current status of antiviral chemotherapy.
- To highlight the mechanisms of action of key antiviral agents.
- To discuss the challenges and future directions in antiviral drug discovery.
Summary:
- Selective antiviral agents, like acyclovir (ACV) for herpes viruses and zidovudine for HIV-1, target virus-specific enzymes.
- Effective antivirals are now available for various viral infections, often with systemic administration and minimal side effects.
- Challenges remain, including delayed toxicity and the emergence of drug resistance, particularly in HIV-1 treatment.
Impact:
- Antiviral chemotherapy has transformed the prognosis of numerous viral diseases.
- Targeting virus-specific enzymes has led to safer and more effective treatments.
- Continued research is essential to develop novel antiviral compounds with improved efficacy and reduced toxicity to address ongoing and emerging viral threats.
