The initial SAR studies indicated:(1) the presence of a linker of methene at the N-1 may be beneficial to anti-HIV activity, while longer chain could enhance toxicity;(2) substituted phenyl at the C-2 could reduce toxicity;(3) 6-substituted benzimidazoles generally showed higher anti-HIV activity than 5-substuted ones;(4) the presence of a halogenated benzyl ring at the N-l would enhance anti-HIV potency and decrease cytotoxicity.
