An objective of the present invention is to provide compounds of formula (I) or their pharmacologically acceptable salts or solvates wherein A represents aryl while R
1
represents a five- or six-membered monocyclic heterocyclic group, or A represents a four- to six-membered monocyclic heterocyclic group while R
1
represents aryl or a five- or six-membered monocyclic heterocyclic group; R
2
represents a hydrogen atom or C
1-6
alkyl; R
3
represents C
1-6
alkyl or C
3-6
cycloalkyl-C
1-4
alkyl; R
4
, R
5
, and R
6
represent a hydrogen atom; R
7
represents C
1-6
alkyl; and m is 1 to 3. The compounds are novel lincosamide derivatives that have a potent activity against resistant
