ABSTRACT The invention relates to novel dipeptide derivatives of the general formula Image (I) wherein R is phenyl, substituted-phenyl, lower cycloalkyl or n-(C4-C6)-alkyl group; R1 and R2 each are hydrogen or methyl, with the proviso that R1 and R2 are not simultaneously a hydrogen, or R1 and R2 together are trimethylene; R3 is acyl derived from a carboxylic acid, a sulphonic acid or a sulphinic acid; and the asterisk denotes that the configuration at the carbon atom so-marked is L when R1 is other than hydrogen. The novel dipeptides can be prepared by methods known per se in peptide chemistry and are useful as elastase inhibitors.
