DYRK1A ATP site with very high efficiency, although with limited selectivity. Structure-guided optimization cycles enabled us to convert this fragment hit into potent and selective DYRK1A inhibitors. Exploiting the structural differences in DYRK1A and its close homologue DYRK2, we were able to fine-tune the selectivity of our inhibitors. Our best compounds potently inhibited DYRK1A in the cell culture

The N-oxide 2 of furo[3,2-b]pyridine (1) was cyanated by the Reissert-Henze reaction with potassium cyanide and benzoyl chloride to give 5-cyano derivative 3, which was converted to the carboxamide 4, carboxylicacid 5, ethyl ester 6 and ethyl imidate 8. Chlorination of 2 with phosphorus oxychloride yielded 2-9a, 3- 9b, 5- 9c and 7-chloro derivative 9d. Reaction of 9d with sodium methoxide, pyrrolidine
通过氰化钾和苯甲酰氯的Reissert-Henze反应使呋喃[3,2- b ]吡啶(1)的N-氧化物2氰化,得到5-氰基衍生物3,将其转化为羧酰胺4羧酸5,乙酯6和亚胺乙酯8。的氯化2用三氯氧化磷,得到2-9A,3- 9B,5- 9C和7-氯衍生物9D。的反应9D与甲醇钠,吡咯烷,N,N-二甲基甲酰胺和氰基乙酸乙酯,得到7-甲氧基- 10,7-(1-吡咯烷基) - 11和7- dimethylaminofuro并[3,2- b ]吡啶(14)和7-(1-氰基-1-乙氧基羰基)亚甲基-4,7-二氢呋喃[3,2- b ]吡啶(12)。用发烟硝酸和硫酸的混合物硝化2,得到2-硝基呋喃并[3,2- b ]吡啶N-氧化物(15)。
