Benzoxazole, benzothiazole or indole oxime derivatives (I) (including analogs with the benzo ring replaced by pyridine, pyrazine, pyrimidine or pyridazine) are new. Benzoxazole, benzothiazole or indole oxime derivatives of formula (I) (including analogs with the benzo ring replaced by pyridine, pyrazine, pyrimidine or pyridazine), and their enantiomers, diastereomers and salts are new.

Independent claims are included for: (1) preparation method of (I); and (2) new ketone intermediates of formula (V). [Image] ACTIVITY : Antidiabetic; Antilipemic; Cardiant; Nephrotropic; Ophthalmological; Antipsoriatic; Gynecological; Nootropic; Osteopathic; Antiinflammatory; Antiarteriosclerotic; Anorectic; Cytostatic. In tests in ob/ob mice, oral administration of 10 mg/kg of methyl 3-(4-(2-(6-((methoxyimino)-(phenyl)-methyl)-2-oxo-1,3-benzothiazol-3(2H)-yl)-ethoxy)-phenyl)-2-(2,2,2-trifluoroethoxy)-propanoate (Ia) twice per day for 4 days reduced blood sugar levels by 51% and reduced the weight gain by 80% in comparison with controls, whereas analogous administration of rosiglitazone reduced blood sugar levels by 61% but increased the weight gain by 33% in comparison with controls. MECHANISM OF ACTION : Aldose Reductase Inhibitor; Angiogenesis Inhibitor.
