synthesised and evaluated as inhibitors of the DNArepair nuclease SNM1A. The series included oxyamides, hydroxamic acids, hydroxamates, a hydrazide, a squarate ester and a squaramide. A hydroxamic acid-derived nucleoside inhibited the enzyme, offering a novel approach for potential therapeutic development through the use of rationally designed nucleoside derived inhibitors.

approach for the synthesis of the 5′-carba analogs of nucleoside 5′-phosphates from 2′-deoxy-5′-O-phthalimidonucleosides by a visible-light-mediated deformylative 1,4-addition was developed. This method enabled rapid and facile generation of 4′-carbon radicals of nucleosides. Moreover, this synthetic strategy was applicable to the 5′-carba analogs of nucleoside 5′-phosphates as well as other 5′-carba nucleosides
