A compound of formula (I) wherein R and R2 together with the nitrogen atom t o which they are attached form pyrrolidinyl or piperidinyl, R1 is a group of formula (II) R3 and R'3 are hydrogen, deuterium or halogen, R4, R5 and R10 a re independently of each other hydrogen or alkyl, R6, R7 and R8 are hydrogen or deuterium; R9 is amino, alkyl, aryl, heterocyclyl or mercapto; and, if X is oxygen, R9 is additionally hydrogen; R'10 is alkyl, X is sulphur, oxygen, NR10, or N+(R'10)2; Y is sulphur or oxygen, and m is 0, 1 or 2; with the proviso that, when R and R2 together with the nitrogen atom to which they ar e attached form piperidinyl, m is O, Y is S and Y is attached in position 3 of said piperidine ring, that group of formula (I) which is attached to the piperidine ring via the residue Y is either in the (S)-configuration or in t he (R)-configuration, preferably in the (S) -configuration which is e.g. useful as antimicrobial, antibacterial.
