And the patent contained the following:
1H-pyrazolo[4,3-g]isoquinoline and 1H-pyrazolo[4,3-g]quinoline derivatives(I) as alpha-1-antitrypsin modulators for treating alpha-1-antitrypsin deficiency (AATD). Compounds I wherein Z1-Z3 each independently -N, -NH, or -CH; V1 and V2 are each selected from C and N; W1 and W2 are each selected from -C=O, -CR2, N, etc.; etc., are claimed. The example compound II was prepared via 4-steps synthesis using (4-chlorophenyl)boronic acid as starting material reacting with intermediate (also prepared)(procedure given). Compounds I were evaluated for alpha-1-antitrypsin modulating activity (data given). Compounds I can be used for the treatment of α1-antitrypsin deficiency. The experimental process involved the reaction of 2-Fluoro-4-hydroxybenzamide(cas: 1133122-96-9).Quality Control of 2-Fluoro-4-hydroxybenzamide
