Abstract
A number of 2'-deoxyribonucleosides of halogenated pyridazine derivatives were prepared by glycosylation of their respective potassium or DBU salts in acetone. The reaction yielded predominatly β-anomers that could be purified by simple crystallization or column chromatography. Of the studied pyridazines and deoxynucleosides, only 4-bromo-6-chloropyridazin-3-one and 6-chloro-2-(2'-deoxyribofuranosyl)pyridazin-3-one showed modest inhibition of CK2 kinase.
