  • Caracemide (NSC-253272) is a novel anticancer agent derived from a hydroxamic acid. Caracemide inactivates R1 by covalent modification at the substrate-binding site and inhibits the enzyme ribonucleotide reductase of Escherichia coli. Caracemide has demonstrated to produce severe central nervous system (CNS) toxicity. Caracemide has a toxic metabolite, methylisocyanate (MIC), in vivo[1][2].
