- Design and synthesis of brain penetrant selective JNK inhibitors with improved pharmacokinetic properties for the prevention of neurodegeneration
-
The SAR of a series of brain penetrant, trisubstituted thiophene based JNK inhibitors with improved pharmacokinetic properties is described. These compounds were designed based on information derived from metabolite identification studies which led to compounds such as 42 with lower clearance, greater brain exposure and longer half life compared to earlier analogs.

- 2-hydroxy-1,5-naphthyridine preparation method
-
The invention relates to the field of chemistry, in particular to a medicinal and chemical intermediate 2-hydroxy-1,5-naphthyridine preparation method. The preparation method includes steps: (1) adding 2-chloro-5-aminopyridine into a sulfuric acid solution, adding an oxidizing agent and a buffering agent under a condition of stirring to obtain a reaction liquid A; (2) dropwise adding glycerin into the reaction liquid A obtained at the step (1), keeping the temperature for 2h, cooling to the room temperature, and adding a solvent to perform dispersion to obtain a reaction liquid B; (3) adding alkaline substances into the reaction liquid B to realize neutralization, and leaching to obtain filter residues; (4) adding a solvent into the filter residues obtained at the step (3), stirring, and leaching to obtain an organic phase; (5) concentrating the organic phase obtained at the step (4), cooling, and leaching to obtain 2-hydroxy-1,5-naphthyridine.
