Urazole is a five-membered heterocyclic compound which is isosteric with uracil's hydrogen-bonding segment. Urazole reacts spontaneoulsy with ribose (and other aldoses) to give a mixture of four ribosides: alpha and beta pyranosides and furanosides. This reaction occurs in aqueous solution

Chlamydiae are obligate intracellular bacteria that are dependent on eukaryotic host cells for ribonucleoside triphosphates but not deoxyribonucleotide triphosphates. Ribonucleotide reductase is the only enzyme known to catalyze the direct conversion of a ribonucleotide to a deoxyribonucleotide. Hydroxyurea inhibits ribonucleotide
