- Novel urate anion transporter 1 (URAT1) inhibitors and application thereof in medicines
-
The invention discloses novel urate anion transporter 1 (URAT1) inhibitors and application thereof in medicines. The novel URAT1 inhibitors are compounds shown in a formula (I) and pharmacologically acceptable salts of the compounds, wherein Y or Z is respectively and independently selected from N or CH; R1 or R2 is respectively and independently selected from H, D, halogen, cyano, hydroxyl, carboxyl, C1-4 alkyl, substituted C1-4 alkyl, C3-4 cycloalkyl, C1-4 alkoxy, substituted C1-4 alkoxy, phenyl, substituted phenyl, heterocyclic aryl or substituted heterocyclic aryl; R3 or R4 is respectively and independently selected from H or C1-3 alkyl, or R3 and R4 form 3-6-membered cycloalkyl together; R5 is H, C1-4 alkyl or substituted C1-4 alkyl. The compounds provided by the invention can be applied to preparation of uric acid excretion promoting medicines, and are especially used for medicines for treating or preventing hyperuricemia or gout. The formula (I) is described in the description.

- New method for the general synthesis of [1,2,4]triazolo[1,5-a]pyridines
-
[1,2,4]Triazolo[1,5-a]pyridines without substituants on the 2-position have been prepared from 2-aminopyridines by cyclization of N-(pyrid-2-yl) formamidoximes with trifluoroacetic anhydride. Triazoles substituted at any position on the pyridine ring may be prepared in good yields and under mild reaction conditions. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
