Compounds of the formula ##STR1## wherein: R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, are selected from the group consisting of hydrogen, alkyl of 1-6 carbons, cycloalkyl of 3 to 6 carbons, alkenyl of 2-6 carbons, or together represent methylene groups --(CH.sub.2).sub.n --where n is a whole number from 1 to 6, provided that R.sub.1 and R.sub.2 or R.sub.3 and R.sub.4 are not both hydrogen; R.sub.5 and R.sub.6, which may be the same or different, are selected from the group consisting of hydrogen, halogen, nitro or --S(O).sub.n R.sub.7 where n is 0, 1 or 2 and R.sub.7 is an optionally substituted alkyl of 1-12 carbons atoms; and both Ar substituents are optionally substituted heteroaromatic rings or one Ar is such heteroaromatic ring and the other is optionally substituted phenyl, the optional substitution for Ar being halogen, nitro or --S(O).sub.n R.sub.7 where n and R.sub.7 have the value given above. The compounds are useful as inhibitors of human neutrophil elastase.

A novel method of treating and preventing viral infection is provided. In particular a method of blocking viral infection facilitated by a serine proteolytic (SP) activity is disclosed, which consists of administering to a subject suffering or about to suffer from viral infection a therapeutically effective amount of a compound having a serine protease inhibitory or serpin activity. Among compounds are α

-antitrypsin (AAT), peptide derivatives from the carboxyterminal end of AAT, and man-made, synthetic compounds mimicking the action of such compounds. The preferred viral infections include retroviral infection such as human immunodeficiency virus (HIV) infection.
