| Abstract |
Efficient synthetic routes of 2-amino-4-(omega-hydroxyalkylamino)pyrimidine derivatives were investigated in relation to the anti-influenza virus activity of these compounds. The derivatives in which cyclobutyl and cyclopentyl groups were introduced to the beta-position of the aminoalkyl group (especially the cyclobutyl group substituted by a phenylalkyl group at the 3'-position) resulted in improved antiviral potency: i.e. an average 50% effective concentration for inhibition of plaque formation (EC50, microM) of 0.1-0.01 microM for both types A and B influenza virus. The antiviral efficacies were in the order of amino group > hydroxyiminomethyl group > halogen substitution at the 5-position, and chlorine or methoxy group > hydrogen at the 6-position of the pyrimidine ring. The antiviral indices of these compounds were 2-6 with respect to the 50% inhibitory concentration for cell proliferation (IC50, microM) for growing cells, but > 500 to > 10(4) with respect to the IC50 for stationary cells, indicating that these compounds may be efficacious for the topical treatment of influenza virus infection.
