The shaded area highlights the hydroxamic acid core of

hydroxyurea. Hydroxamic acids avidly bind heavy metals

and inactivate a variety of enzymes. Hydroxyurea

inhibits the iron-containing enzyme ribonucleotide reductase,

thereby killing cycling cells. Hydroxyurea also

produces nitric oxide and stimulates the heme-iron–

containing enzyme guanylate cyclase. Both activities

have the potential to increase F-cell production.
