Selective virus inhibitors

Area of Science:

• Virology
• Medicinal Chemistry
• Drug Discovery

Background:

• Viral infections pose significant global health challenges.
• Development of broad-spectrum antiviral agents remains a critical need.
• Targeting essential viral enzymes and processes is a key strategy in antiviral drug design.

Purpose of the Study:

• To develop selective inhibitors against various classes of viruses.
• To identify novel molecular targets for antiviral drug development.
• To synthesize and evaluate new chemical entities with antiviral activity.

Main Methods:

• Design and synthesis of novel nucleoside and non-nucleoside analogs.
• Identification of molecular targets including viral DNA polymerase, SAH hydrolase, and reverse transcriptase.
• Evaluation of antiviral activity against DNA viruses (adeno, pox, herpesviruses), RNA viruses ((+/-)RNA, (-)RNA), and retroviruses (HIV).
• Investigation of inhibitors targeting virus adsorption to cell membranes.

Main Results:

• Several new compounds demonstrated potent antiviral activity.
• Bromovinyldeoxyuridine (BVDU) derivatives and acyclovir derivatives showed efficacy against herpesviruses.
• (S)-HPMPA, PMEA, and other phosphonylmethoxyalkylpurines/pyrimidines inhibited DNA viruses and retroviruses.
• Adenosine analogs and 2',3'-dideoxynucleoside analogs were effective against RNA and retroviruses, respectively.
• Sulfated polysaccharides and polymers inhibited enveloped viruses.

Conclusions:

• Novel antiviral compounds targeting diverse viral mechanisms have been successfully developed.
• The identified compounds represent promising candidates for the treatment of various viral infections.
• Further research and clinical trials are warranted to explore the therapeutic potential of these antiviral agents.
