Discovery and Optimization of Selective Nav1.8 Modulator Series That Demonstrate Efficacy in Preclinical Models of Pain
摘要:
Voltage-gated sodium channels, in particular Na(v)1.8, can be targeted for the treatment of neuropathic and inflammatory pain. Herein, we described the optimization of Na(v)1.8 modulator series to deliver subtype selective, state, and use-dependent chemical matter that is efficacious in preclinical models of neuropathic and inflammatory pain.

We report the late-stage functionalization of multisubstituted pyridines and diazines at the position α to nitrogen. By this process, a series of functional groups and substituents bound to the ring through nitrogen, oxygen, sulfur, or carbon are installed. This functionalization is accomplished by a combination of fluorination and nucleophilicaromaticsubstitution of the installed fluoride. A diverse

The present invention relates to compounds of Formula I that function as inhibitors of RET (rearranged during transfection) kinase enzyme activity: wherein HET, bonds a, b, c and d, X1, X2, X3, X4, R2, and R3 are each as defined herein. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of proliferative disorders, such as cancer, as well as other diseases or conditions in which RET kinase activity is implicated.
The present invention relates to compounds of the formula (I) and pharmaceutically acceptable salts and solvates thereof, to processes for the preparation of, intermediates used in the preparation of, and compositions containing such compounds and the uses of such compounds for the treatment of pain.

The present invention provides compositions and methods for the selective C—H fluorination of nitrogen-containing heteroarenes with AgF
2
, which has previously been considered too reactive for practical, selective C—H fluorination. Fluorinated heteroarenes are prevalent in numerous pharmaceuticals, agrochemicals and materials. However, the reactions used to introduce fluorine into these molecules require pre-functionalized substrates or the use of F
2
gas. The present invention provides a mild and general method for the C—H fluorination of nitrogen-containing heteroarene compounds to 2-fluoro-heteroarenes with commercially available AgF
2
. In various embodiments, these reactions occur at ambient temperature within one hour and occur with exclusive selectivity for fluorination at the 2-position. Exemplary reaction conditions are effective for fluorinating diazine heteroarenes to form a single fluorinated isomer.
