The invention concerns compounds of formula (I) which modulate, especially agonize alpha kinase 1 (ALPK1) and are useful for treating a condition, disease or disorder in which a decrease or increase in ALPK1 activity contributes to the pathology or symptoms or progression of the condition, disease or disorder such as cancer, immune or inflammatory related diseases.
electrophilic activation of 5′-phosphorothioate nucleotides. The treatment of phosphorothioate with 2,4-dinitrochlorobenzene (DNCB) efficiently afforded the key activated species, electrophilic thioester nucleotides (EPT-Ns), which were coupled with various phosphate reagents to afford the target nucleoside oligophosphates, including an mRNA cap analog.
We describe a general method for the elongation of nucleoside oligophosphate chains by means of cyanoethyl (CE) phosphorimidazolides. Though the method requires a phosphorylation and subsequent deprotection reaction, both steps could be achieved in one pot without isolation/purification of the initial phosphorylation product. We have also found that pyrophosphate bond formation by this method is significantly accelerated by microwave irradiation.
