摘要:
One-pot benzimidazole syntheses have been used to prepare an extended series of novel analogues which were evaluated against HIV-1 infectivity, the most active having an EC(50) of 0.5 mu M. There is a correlation between the length of saturated alkyl groups at O1 and C2 with antiviral selectivity. Replacing vinyl by the 2,2-dimethyl vinyl group increases antiviral selectivity.
