2,6-Di(arylamino)-3-fluoropyridine Derivatives as HIV Non-Nucleoside Reverse Transcriptase Inhibitors

Area of Science:

• Medicinal Chemistry
• Organic Synthesis
• Virology

Background:

• Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are crucial in HIV therapy.
• Previous NNRTIs include di(arylamino)pyrimidines.
• Development of novel NNRTIs with improved activity is ongoing.

Purpose of the Study:

• To synthesize and evaluate novel fluorinated NNRTIs.
• To investigate the impact of fluorine incorporation on anti-HIV activity.
• To explore new synthetic routes for NNRTIs.

Main Methods:

• Synthesis of novel 2,6-di(arylamino)-3-fluoropyridine, 2,4-di(arylamino)-5-fluoropyrimidine, and 1,3-di(arylamino)-4-fluorobenzene derivatives.
• Utilized two sequential palladium-catalyzed amination reactions for synthesis.
• Evaluated in vitro anti-HIV activity against wild-type and drug-resistant strains.

Main Results:

• Successfully synthesized novel fluorinated pyridine, pyrimidine, and benzene derivatives.
• Demonstrated that the presence of fluorine significantly enhances in vitro anti-HIV activity.
• Achieved potent activity against both wild-type and mutant HIV strains.

Conclusions:

• Fluorinated NNRTIs represent a promising class of antiviral agents.
• The synthetic strategy provides a practical route to these novel compounds.
• Fluorine incorporation is a valuable approach for improving NNRTI efficacy.
