Pyrimidines for treatment of bacterial infections

A pyrimidine having the structure of formula (I):

• wherein R1 represents alkyl having 1-10 carbon atoms, aryl having one or two 6-membered aromatic rings, or heteroaryl having one or two 6-membered aromatic rings with at least one nitrogen (N) as the heteroatom;
• R2 represents an aryl or heteroaryl group;
• and
• R3 represents
• or —N(R8)—[CH2]m—N(R9)(R10), wherein
• R6 is selected from the group consisting of alkyl having 1-10 carbon atoms, optionally substituted benzyl, optionally substituted phenyl, pyridylmethyl, optionally substituted benzoyl, optionally substituted phenethyl, piperonyl, 3-phenyl-2-propen-1-yl, optionally substituted cinnamoyl, alkyl sulphonyl, aryl sulphonyl and heteroaryl sulphonyl;
• R7 is selected from the group consisting of alkyl having 1-10 carbon atoms, optionally substituted benzyl, optionally substituted phenyl, pyridylmethyl, optionally substituted benzoyl, optionally substituted phenethyl, piperonyl, 3-phenyl-2-propen-1-yl, optionally substituted cinnamoyl, alkyl sulphonyl, aryl sulphonyl and heteroaryl sulphonyl;
• each of R8, R9 and R10 is independently selected from the group consisting of alkyl having 1-5 carbon atoms, and optionally substituted benzyl;
• and
• m is an integer selected from 2, 3, 4 and 5.
