The invention relates to Imidazolo-heteroaryl derivatives of formula (I)
The compounds inhibit the activity of the Dlta enzyme of Gram-positive bacteria and are useful to treat Gram-positive bacterial infections.
Furthermore the application discloses method for assessing the Dlta inhibitory activity of tested molecules and a method for measuring the efficacy of molecules in inhibiting bacteria proliferation in vitro.
The present invention relates to a compound represented by Formula (I):
(wherein Ar
1
represents an imidazolyl group which may be substituted with 1 to 3 substituents; Ar
2
represents a pyridinyl group, a pyrimidinyl group, or a phenyl group which may be substituted with 1 to 3 substituents; X
1
represents (1) —C≡C— or (2) a double bond etc. which may be substituted; R
1
and R
2
represent, for example, a C1-6 alkyl group or C3-8 cycloalkyl group which may be substituted)
or a pharmacologically acceptable salt thereof and to the use thereof as pharmaceutical agents. The object of the present invention is to find a therapeutic or preventive agent for diseases caused by Aβ. According to the present invention, a therapeutic or preventive agents for diseases caused by Aβ can be provided.
