Novel cyclohexyl-amides as potent antibacterials targeting bacterial type IIA topoisomerases
摘要:
As part of our wider efforts to exploit novel mode of action antibacterials, we have discovered a series of cyclohexyl-amide compounds that has good Gram positive and Gram negative potency. The mechanism of action is via inhibition of bacterial topoisomerases II and IV. We have investigated various subunits in this series and report advanced studies on compound 7 which demonstrates good PK and in vivo efficacy properties. (C) 2011 Elsevier Ltd. All rights reserved.
Cyclohexane and cyclohexene derivatives and pharmaceutically acceptable derivatives thereof useful in methods of treatment of bacterial infections in mammals, particularly man. A compound of formula (I) or a pharmaceutically acceptable derivative thereof: (I) RA is an optionally substituted bicyclic carbocyclic or heterocyclic ring system of structure: containing 0-3 heteroatmoms in each ring in which: at least one of the rings (x) and (y) is aromatic; one of Z4 and Z5 is C or N and the other is C; Z3 is N, NR13, O, S(O)x, CO, CR1 or CR1R1a; Z1 and Z2 are indendently a 2 or 3 atom linker group each atom of which is independently selected from N, NR13, O, S(O)x, CO, CR1, and CR1R1a; such that each ring is independently substituted with 0-3 groups R1 and/or R1a. R4 is a group -CH2-R51in which R51 is selected from: (C4-8) alkyl; hydroxy (C4-8) alkyl; (C1-4)alkoxy (C4-8)alkyl; (C1-4) alkanoyloxy (C4-8) alkyl; (C3-8)cycloalkyl (C 4-8)alkyl;hydroxy-, (C1-6) alkoxy- or (C1-6) alkanoyloxy-(C3-8)cycloalkyl (C4-8)alkyl; cyano(C4-8)alkyl; (C4-8)alkenyl; (C4-8)alkynyl; tetrahydrofuryl; mono- or di-(C1-6)alkylamino (C4-8)alkyl; acylamino (C4-8)alkyl; C(1-6)alkyl- or acyl-aminocarbonyl (C4-8) alkyl; mono- or di- (C1-6)alkylamino(hydroxy) (C4-8)alkyl; or R4 is a group-U-R52 where R52 is an optionally substituted bicyclic carbocyclic or heterocyclic ring system (A): containing up to four heteroatoms in each ring in which at least one of rings (a) and (b) is aromatic; X1 is C or N when part of an aromatic ring or CR14 when part of a non-aromatic ring.
