A compound of formula (I) wherein R and R 2 and the attached nitrogen atom form pyrrolidinyl or piperidinyl. R 1 is a group of formula (II). R 3 and R′ 3 are hydrogen, deuterium or halogen. R 4 , R 5 and R 10 are independently of each other hydrogen or alkyl. R 6 , R 7 and R 8 are hydrogen or deuterium. R 9 is amino, alkyl, aryl, heterocyclyl or mercapto. If X is oxygen, R 9 is additionally hydrogen; R′ 10 is alkyl, X is sulphur, oxygen, NR 10 , or N+(R′ 10 ) 2 ; Y is sulphur or oxygen, and m is 0,1 or 2, with the proviso that, when R and R 2 and the attached nitrogen atom form piperidinyl, m is O, Y is S and Y is attached in position 3 of the 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 the (R)-configuration, preferably in the (S)-configuration which is useful as antimicrobial, antibacterial. |
