The invention provides a compound of the formula (I): for use in medicine: or salts or tautomers or N-oxides or solvates thereof; wherein R1 is an optionally substituted heterocyclic group having from 3 to 12 ring members provided that the cyclic group joined to the pyrazole contains at least one heteroatom selected from N, O or S; A is a bond or -Y-(B)n-; B is C=O, NRg(C=O) or O(C=O) wherein Rg is hydrogen or C1-4 hydrocarbyl optionally substituted by hydroxy or C1-4 alkoxy; n is 0 or 1; Y is a bond or an alkylene chain of 1,2 or 3 carbon atoms in length; R2 is hydrogen; halogen; C1-4 alkoxy (e.g. methoxy); or a C1-4 hydrocarbyl group optionally substituted by halogen (e.g. fluorine), hydroxyl or C1-4 alkoxy (e.g. methoxy); R3 is selected from optionally substituted carbocyclic and heterocyclic groups having from 3 to 12 ring members or an optionally substituted C1-8 hydrocarbyl group; with the proviso that R1 is not formula (II): where X, R3’ and R4’ are defined in the claims.

Oxazolidinone derivatives containing pyridine substituted with heteroaromatic ring were synthesized and exhibited potent in vitro and in vivo antibacterial activities against many antibiotic-resistant microbial strains. A series of oxazolidinone derivatives, which morpholino group of linezolid was replaced with heteroaromatic ring substituted pyridine moiety, were newly synthesized, and their substituted effects on in vitro and in vivo antibacterial activities were evaluated against four problematic gram-positive strains including drug resistant strains and two gram-negative strains. Most compounds exhibited the enhanced in vitro activities with 4-16-fold and three compounds exerted more than 2-fold increased in vivo efficacies than linezolid.
