    Abstract: 6-Substituted ketolides of e.g. formula (II) or (III), and their salts, esters and prodrugs are new: Y + Z = X; X = OH, =NOR1 or =NOC(R5)(R6)OR1; or one of Y and Z = H; and the other = H, OH, protected OH or NR7R8; R1 = 1-12C alkyl (optionally substituted), 3-12C cycloalkyl or SiR2R3R4; R2-R4 = 1-12C alkyl or aryl; R5, R6 = H or 1-12C alkyl (optionally substituted), or R5 + R6 = 3-12C cycloalkyl; R7, R8 = H or 1-6C alkyl; or NR7R8 = 3-7 membered ring which, when the ring is 5-7 membered may optionally contain O, NH, N(1-6C alkyl), N(aryl), N(aryl-1-6C alkyl), N (substituted aryl-1-6C alkyl), N(heteroaryl), N(heteroaryl-1-6C alkyl), N(substituted heteroaryl-1-6C alkyl), S or S(O)n; n = 1 or 2; Ra = H or OH; Rc = H or hydroxy protecting group; R9 = 1-6C alkyl (optionally substituted), 3-7C cycloalkyl or optionally substituted aryl or heteroaryl; M = CONH, NHCO, NH, N=, NMe, NHCOO, NHCONH, OCONHY, OCOO, O, S(O)n, COO, OCO or CO; R = methyl (substituted by CN, F, CO2R10, S(O)nR10, NHCOR10, NHCONR11R12, aryl, substituted aryl, heteroaryl or substituted heteroaryl); 2-10C alkyl (optionally substituted), 3C alkenyl (substituted by halo, CHO, CO2R10, COR9, CONR11R12, CN, optionally substituted aryl or heteroaryl, 3-7C cycloalkyl or 1-12C alkyl substituted by heteroaryl); 4-10C alkenyl (optionally substituted), or 3-10C alkynyl optionally substituted); R10 = 1-3C alkyl (optionally aryl substituted), or heteroaryl substituted 1-3C alkyl; R11, R12 = H or 1-3C alkyl (optionally substituted); A, B, D, E = H, 1-6C alkyl (optionally substituted by optionally substituted), 3-7C cycloalkyl, optionally substituted aryl or heteroaryl, heterocycloalkyl or 1-6C alkyl substituted by MR9; provided that \- 2 of A, B, D and E = H; or any one pair of substituents, consisting of AB, AD, AE, BD, BE or DE taken with the atoms to which they are attached, form a 3- to 7-membered ring optionally containing O, NH, N(1-6C alkyl), N(aryl-1-6C alkyl), N(substituted aryl-1-6C alkyl), N(heteroaryl-1-6C alkyl), N(substituted heteroaryl-1-6C alkyl), S, S(O)n, CONH, CONR12, NHCO, NR12CO or C(=NH)NH.
